MasterLife ® WP 707 (Formerly known as Rheomac 707)

Low dosage, liquid, integral waterproofer DESCRIPTION

A liquid admixture for concrete to give high water resistance, based upon a blend of surface active agents and refined lignosulphonate. Waterproof concrete is the result of good concrete practice coupled with the lowest w/c ratio compatible with achieving full compaction. The use of MasterLife WP 707 enables all these criteria to be met due to its strong plasticising and water reducing properties. PRIMARY USES

MasterLife WP 707 should be used in all structural concrete that is constantly or intermittently in contact with water such as sea walls, tunnels, basements, structural and pre-cast concrete in exposed superstructures. ADVANTAGES

• Concrete containing MasterLife WP 707 is resistant to water penetration either under conditions of hydrostatic pressure or capillary absorption.

• Durability is increased due to a significant reduction in w/c ratio.

• Sulphate attack is reduced due to the sulphate bearing ground water being resisted.

• The cohesive properties of the concrete are improved thus reducing segregation and bleeding.

• Concrete of similar workability to a control mix produced with MasterLife WP 707 , is easier to place.

• Pumpability of concrete is greatly improved. • The surface finish of the concrete is

improved. PACKAGING

MasterLife WP 707 is available in bulk or 210 litre drums.

ACTION MasterLife WP 707 assists in the production of water resistant concrete by its two fold action: I. It significantly reduces water demand to

enable production of good workability concrete with a minimum water/cement ratio.

II. It disrupts the cellular network within the concrete mass (capillaries), that are normally inter-connected thereby reducing the concrete permeability. Test results using Initial Surface Absorption Tests (ISAT) in accordance with BS 1881: Part 5: 1970, on concrete with MasterLife WP 707 show a decrease in surface absorption of between 60-80% over a similar concrete without MasterLife WP 707 .

COMPOSITION

A blend of specially selected surface active agents and refined lignosulphonates. * TYPICAL PROPERTIES

Colour: Brown liquid. Specific gravity: 1.185 At 25°C. Air entrainment: 2 ± 1% according to grading

of sand and water content. Chloride content: Nil to BS 5075. Nitrate content: Nil. Freezing point:: 0°C. Can be reconstituted if

stirred after thawing. STANDARDS

EN 934-2 Table 2 ASTM C494: Types A & D.


DIRECTIONS FOR USE

MasterLife WP 707 should be added with the mixing water preferably via a dispenser. It should never be added to the dry cement. No extensions to mixing times are required. Points to remember when producing waterproof concrete: • Ensure specified water / cement ratio is not

exceeded; work within the range of 0.4 to 0.6.

• Keep water content as low as possible compatible with achieving full compaction.

• Place concrete quickly and ensure it is thoroughly compacted.

• Protect new concrete against rapid drying out and ensure adequate and complete curing with BASF's MasterKure curing compounds.

DOSAGE 320ml per 100kg of cement. Field trials should be conducted to determine the effect of MasterLife WP 707 on the workability of the concrete.

EFFECTS OF OVER DOSAGE • Slight set retardation. (No effect on striking

times). • Slight increase in air content. • Increase in workability.

SPECIAL FEATURES Advantage of MasterLife WP 707 strong plasticising action must be taken to reduce water contents to a minimum. A reduction in w/c ratio in the region of 10 to 15% can generally be achieved.

DISPENSING MasterLife WP 707 should be dispensed through a proprietary dispenser such as those available from BASF. Details upon request.

MasterSeal ® 345

Spray applied waterproofing membrane for tunnel con crete composite shell linings DESCRIPTION

MasterSeal 345 is an EVA polymer based, sprayable membrane for the waterproofing of underground concrete structures. It is spray applied in a sandwich structure between two sprayed concrete / cast concrete layers, creating a double bonded composite shell lining. It is flexible and has very high bond strength properties on both sides of the membrane. It is an effective alternative to conventional waterproofing sheet membranes. As a double bonded system, this provides excellent water tightness, preventing the development of water migration on both sides of the membrane. As with all spray applied membranes, it is not possible to seal against water ingress through the substrate. In such cases a drainage system or local water management using drainage pipes should be used in combination with MasterSeal 345. However, it can be applied to damp substrate (as long as there is no running water). FIELDS OF APPLICATION

• Suitable for all types of tunnel designs • Particularly well suited for underground

structures with complex profiles and geometry such as stations, escape and access tunnels, utility caverns, cross passages and tunnel intersections

• Enables tunnel design with composite shell lining to reduce excavation cross section and lining thickness, and is especially suited to tunnel rehabilitations

FEATURES AND BENEFITS • Fast curing • Easy to use, only addition of water

needed • Application by spraying with simple

equipment • Elasticity 80% to 140% between -20 0C

and +20 0C • No toxic components • No classification needed for transport PACKAGING

JOINT PREPARATION

1. The number of joints and the joint width should be designed for a maximum of ±25% movement.

2. The width to depth ratio of the sealant should be 1:1 to 1.5:1 subject to a minimum 10mm depth.

3. In deep joints use closed cell backer-rod or soft backer-rod. Where the joint depth does not permit the use of backer-rod, a bondbreaker (polyethylene strip) must be used to prevent three-point bonding.


4. To maintain the recommended sealant depth,

compress and roll backer-rod into the joint channel without stretching it lengthwise. Backer-Rod should be about 3mm larger in diameter than the width of the joint. Soft backer-rod should be approximately 25% larger in diameter than the joint width. Do not prime or puncture Backer-Rod.

SURFACE PREPARATION:

1. Joint faces must be structurally sound, clean, dry, and free of all loose aggregate, paint, oil, grease, wax, mastic compounds, waterproofing compounds, form release agents and other contamination.

2. New concrete: Remove all loose material by wire brushing. Sandblast surfaces that have been in contact with form release agents. Fresh concrete must be fully cured at least 28 days. Laitance must be removed by abrading.

3. Old concrete previously caulked: Remove old joint sealing material by mechanical means. If joint sides have absorbed oils, cut away sufficient concrete to ensure a clean surface.

PRIMING:

1. Concrete surfaces to receive MasterSeal 475 should be primed with MasterSeal P 175 .

2. Prime steel in contact with MasterSeal 475 with MasterSeal P 175 after cleaning to bright metal.

3. Apply primer in a thin, uniform film; avoid build-up of excess primer.

4. Allow approximately 30 to 120 minutes drying time; before applying sealant.

5. Where MasterSeal 475 is to be used in contact with asphalt please contact BASF Technical Department for advice regarding the use of MasterEmaco P 102 as primer.

APPLICATION:

1. MasterSeal 475 can be poured from a can or applied by gun. Fill joint from bottom to prevent formation of air voids.

2. Avoid application at extremely low temperatures to prevent moisture condensation and excessive thickening of the sealant.

CLEAN UP

Immediately after use, wash tools with MasterTop THN 2 . (Observe all precautions when handling solvents). FOR BEST PERFORMANCE

• Protect MasterSeal 475 from traffic until fully cured.

• Do not use on surfaces having a high crown or marked degree of slope.

• Do not paint MasterSeal 475 . • Do not apply over asphalt damp-proofing or

asphalt-impregnated joint fillers. • Do not apply sealant if bed beneath deck or

substrate has become saturated with water. • Do not allow MasterSeal 475 to come in

contact with alcohol-based material or solvents.

• Make certain the most current version of this data guide is being used.

• Proper storage and application is the responsibility of the user.

MasterSeal® 501

Surface applied capillary waterproofing system for concrete and block work DESCRIPTION

The MasterSeal 501 waterproofing system ensures a total and permanent solution to water leakage, ingress, or seepage in concrete structures or any cementitious substrate. The formation and development of insoluble crystals into water bearing capillaries and interstices effectively blocks the further passage of water. Supplied as a powder and mixed to a slurry consistency with potable water. MasterSeal 501 is applied directly to concrete, blockwork or cement renders in areas where general waterproofing is required. In powder form, the product may be used as a dry shake on horizontal construction joints. ADVANTAGES

Provides total and permanent waterproofing properties by becoming an integral part of the structure to which it is applied. Active ingredients will not delaminate, peel off or wear away.

Protects concrete and reinforcement against corrosive waterborne substances.

Crystalline action is reactivated by contact with water providing permanent and continuous protection.

Effective against both positive and negative water pressure.

TYPICAL APPLICATIONS

WATER RETAINING WATER EXCLUDING Water tanks / towers Basements Reservoirs Tunnels Water treatment work Inspection pits Dams Foundations Canals Retaining walls Harbours Lift shafts Concrete pipes Construction joints Sea defence walls Bridge decks Jetties Pontoons

PACKAGING MasterSeal 501 is supplied in 25kg bags.

COMPOSITION MasterSeal 501 consists of a blend of moisture activated chemicals, high grade silica aggregates and selected cements.

ACTION Moisture and free lime present in the substrate react with the active chemicals in MasterSeal 501 to create a continuous barrier of insoluble crystals. The crystal formation will penetrate deep into the capillary structure of the concrete, blocking capillaries and interstices from the passage of water, whilst permitting the transmission of air and water vapour, enabling the structure to breathe. Rate and penetration of crystalline development varies with the density and surface absorption of the concrete, but the crystals will penetrate to the depth to which water is present. MasterSeal 501 is equally effective against both negative and positive water or osmotic pressure and can be applied to the internal or external surface. Wherever possible however, MasterSeal 501 should be applied to the surface with which the water is in direct contact. This will result in an accelerated rate of penetration and crystallisation into the concrete structure. After the crystallisation process has successfully waterproofed the structure, the MasterSeal 501 active chemicals remain dormant in the concrete. Any later contact with water will reactivate the sealing process. DIRECTION FOR USE

New Construction: The vast majority of leaking water retaining (or excluding) structures constructed of sound dense concrete, leak only at construction or day work joints. Costly remedial work can be avoided by the use of MasterSeal 501 as a dry shake onto the horizontal surfaces of joints or as a slurry application on vertical surfaces.

MasterSeal® 501

In conditions of high water table MasterSeal 501 may be applied as a slurry or dry shake over blinding concrete immediately prior to casting the slab. This sandwich system will prevent ingress of ground water preventing deterioration, and dampness or flooding. Foundations should be treated on the external face wherever possible, as should the face of construction joints. MasterSeal 501 can be applied immediately after the formwork has been removed, as the water curing process required for MasterSeal 501 will also ensure full hydration of the concrete. If the treatment is to be exposed and an aesthetically pleasing finish is required, the MasterSeal 501 after curing, should receive a sand/cement render on which to apply the desired finish. Existing structures Structures subject to water leakage or ingress, must be carefully inspected to determine the cause. Any water present should be cleared away so that a thorough survey can be conducted. Static cracks over 1mm must be chased out, dampened down and repaired with MasterSeal 590. Dynamic cracks should be sealed by injection with MasterSeal 901 or MasterInject 1320. SURFACE PREPARATION

In common with all surface treatments to concrete, the quality of substrate preparation directly affects the performance system. Surfaces to be treated must be free from dust, oil, grease, paint, residual curing compound, mould oil or any previous surface treatment that will impair adhesion of the MasterSeal 501 treatment, or inhibit penetration of the chemicals or water into the surface. These include polymer modified renders and those substrates treated with silicon or silane water repellents. Remove any laitance and provide an open pored, slightly rough surface sufficient to act as a mechanical key, essential for adequate adhesion of the MasterSeal 501 treatment. Light sand / grit blasting of the concrete surface is the preferred method of surface preparation. Areas of weak or honeycombed concrete must be repaired. Hollow, debonding renders must be removed and made good.

Surfaces to be treated if not already wet, should be saturated for a period of 24 hours before first applications. MasterSeal 501 system technology requires the presence of water for the active chemicals to migrate into the concrete. Crystalline development will usually extend to the depth of water penetration. MIXING

Always add water to MasterSeal 501 – not in reverse order. Mix 1 part of water to 2.25 – 2.5 parts of MasterSeal powder by volume. Mix only sufficient MasterSeal that can be used in 20 minutes. APPLICATION

MasterSeal 501 mixes are applied by brush or spray onto the dampened substrate. Apply the material in 2 coats at right angles, the second coat whilst the first is firm, but ‘green’ – usually 3-4 hours after first coat (dependant on temperature). PLUGGING LEAKS

Leaks and holes drilled to relieve water pressure may be sealed permanently using MasterSeal 590. To plug leaks under pressure, chase out the area of the leak until water flow is free and insert a length of plastic hose. Seal around the plastic hose with plugging compound as above. Clean the cavity with mortar and allow to cure. When surrounding waterproofing is complete, withdraw the hose and plug the hole with plugging compound as above, using a gloved thumb to hold it in place until set (approximately 1 minute). When the mortar has set, complete the waterproofing, lapping slurry coats of MasterSeal 501 onto the concrete surrounding the hole. Holes under low pressure can be similarly sealed, but pipe insertion and MasterSeal 590 technical datasheet prior to use. CURING

The MasterSeal 501 must be prevented from drying out too rapidly and should be kept continuously damp for 5-7 days. Mist spraying with water and covering with polythene is effective when drying out would otherwise take place. Curing compounds are unsuitable for use with MasterSeal 501 system technology.

MasterSeal ® 550

Acrylic reinforced cementitious, flexible waterproo f coating

DESCRIPTION MasterSeal 550 is a two component acrylic modified cementitious coating that requires only on site mixing to form the ideal product to waterproof and resurface concrete, masonry, and most other construction materials. Simply applied by stiff brush, roller, or trowel, it forms a waterproof, flexible coating. MasterSeal 550 provides an effective barrier to waterborne salts and atmospheric gases. Fluid applied, MasterSeal 550 provides a hard wearing, seamless, waterproof membrane for roofs and foundation protection. TYPICAL APPLICATIONS

• To reface and even out variations in concrete surfaces.

• As a waterproof lining for water retaining structures.

• For coating seawater channels. • Sealing and coating tie bar holes to ensure

watertightness. • For waterproofing and protection against

brackish water. • To provide foundation protection. • As a waterproof coating for roofs. • As a backing to marble and granite to prevent

water ingress and thus alleviate surface staining.

• To provide protection to concrete surfaces from carbonation and chloride attack.

• For use on pedestrian walkways in marine areas.

PACKAGING

MasterSeal 550 is available in 20kg double pack. MasterSeal 550 is available in three standard colours : Light Grey, White and Dark Grey.

ADVANTAGES • Waterproof • Excellent adhesion. Bonds to porous and non-

porous surfaces. • Flexible. • Non toxic suitable for contact with potable

water. • Suitable for light pedestrian traffic. • Breathable - whilst repelling water, allows

substrate to breathe. • High resistance to chloride ion diffusion. • Unlike conventional coatings which require a 7-

28 day cure of concrete, MasterSeal 550 can be applied to 24 hour-old concrete thereby giving immediate protection.

COMPOSITION

MasterSeal 550 is composed of specially selected cements, silica sand and reactive fillers supplied in powder form together with a liquid component of blended acrylic copolymers and wetting agents. TYPICAL PROPERTIES*

Density: 1826kg/m³ Toxicity: Non toxic - Suitable for

use in contact with potable water

MasterSeal ® 550

CHLORIDE ION DIFFUSIVITY

MasterSeal 550 provides an effective barrier to waterborne salts such as chlorides and sulphates. *lndependent assessment has shown that even after 12 months constant immersion the chloride ion diffusion co-efficient could not be measured for MasterSeal 550 . CHEMICAL RESISTANCE

MasterSeal 550 has outstanding wear and weather resistance and good resistance to gasoline, diesel oil, sodium hydroxide, calcium chloride, de-icing salts. MasterSeal 550 coated surfaces exhibit good resistance to mild acids. ANTI CARBONATION COATING

MasterSeal 550 is an extremely effective barrier to atmospheric acidic gases which cause carbonation in concrete structures. MasterSeal 550 at an applied rate of 1.8 kg/m² gives an equivalent air layer thickness for carbon dioxide diffusion (R) of 92 metres. The accepted minimum value for R is 50m. Testing to confirm this was carried out independently by Taywood Engineering 2005. A report is available on request. APPLICATION PROCEDURE

Surface preparation: As with all coating systems, surface preparation is of prime importance. Remove all grease, oil, dust, residual curing compound, mould release agent or other contaminant that could impair adhesion. Laitance should preferably be removed by light sweep blasting or hydro-jetting. Mechanical wire brushing may be appropriate for small areas. Spalled concrete should be cut back to sound concrete and made good with a suitable cementitious repair mortar such as MasterEmaco S 488 . Conventional concrete curing compounds should be removed before application. The exception to this is when MasterKure 181 has been used. Roofing tiles should be firmly bedded and grouted before application.

MIXING

MasterSeal 550 is supplied in premeasured units and should be mixed on site utilising clean containers. Slowly add the powder to the liquid and mix, using a slow speed drill fitted with a suitable paddle. MIX AND USE. Do not mix more material than can be used in one hour. NOTE: Although MasterSeal 550 is supplied in premeasured packs, part packs can be used by mixing 2 volumes of powder to 1 volume of liquid. Mix thoroughly and keep mixed during application. DO NOT RE-TEMPER WITH WATER. APPLICATION

Do not apply to dry concrete Saturate concrete surfaces with clean water whilst still visibly damp, but free of standing water, apply, using a short, stiff bristle brush or roller. Trowel application can be undertaken as necessary. For heavy 6-10mm depressions, honeycombs etc. use less gauging liquid and mix to the desired consistency. Where more than one coat is found necessary to achieve the desired thickness, apply the second or subsequent coats after the previous coat has dried. It is recommended, for general resurfacing, that each coat should be a minimum of 1mm thick. Spray application is recommended for large areas, details of suitable equipment can be provided by BASF’s Technical Service Dept. COVERAGE

APPLICATION

Substrate preparation: The surface to be coated must be clean and sound. Remove all traces of formwork, release agents, previous coatings, laitance, organic growth and any other contaminants that may affect the bond adversely. Suitable cleaning methods include ultra high-pressure water treatment and grit


blasting. Aggressive percussive methods such as scabbling or scaryifying are not recommended unless followed by grit blasting, wire bushing or high pressure water jetting. After the above treatment, surfaces must be thoroughly rinsed with clean potable water to remove all dust and loose particles. Cracks and bolt holes must be cut out and filled solid with MasterSeal 590 . Blowholes in the concrete should be filled with a thixotropic mix of MasterSeal 588 .

MIXING

Pot life 60 minutes Drying time 360 minutes

MIXING LIQUID BRUSH OR ROLLER APPLICATION

±10.0 litres MasterSeal 588 Liquid / 25 kg powder.

SPRAY APPLICATION Max. 10.8 litres of MasterSeal 588 Liquid / 25 kg powder can be used. MasterSeal 588 should be power mixed only, using a suitable double helix mixer attachment in a slow-speed drill (400 - 600 rpm). DO NOT use free fall type mortar mixers. Blend 25 kilograms of powder into a approximately 10.0 litres of liquid. The quantity of liquid will vary slightly depending upon the application method and ambient conditions. Mix maximum for a maximum of 3 minutes and until a lump-free consistency is achieved. Allow a slake time of 5 minutes and remix for maximum 2 minutes adding powder or liquid when necessary to obtain the correct consistency. Do not exceed the maximum liquid demand. Do not overmix. For colour uniformity always mix with the same amount of liquid.

Provide adequate ventilation when mixing and applying MasterSeal 588 .

APPLICATION Do not apply MasterSeal 588 to frozen substrates or if the ambient temperature is below 5ºC or expected to fall below 5ºC within 24 hours. Avoid application in direct sunlight. Always apply the mix to a pre-dampened surface. High suction substrates require more dampening then dense substrates. However, make sure there is no free-standing water. Mixed material must be used within 60 minutes, or less under hot weather conditions. First coat: Brush, broom or spray the mix onto the pre-dampened, prepared surface, brushing well into the surface. Strike off with the brush or broom in one direction for a neat appearance. Care must be taken not to spread the material too thinly. Typical layer thickness is approximately 1.0 mm. When the material begins to drag or “ball”, do not add more liquid, but dampen the surface again. Spray through a 3 - 4 mm nozzle at a pressure of 3.6 – 5.0 bar. Reinforcing with BASF approved mesh: BASF Approved Mesh is embedded in a thin base layer of approximately 0.5 mm thick, covered with the first coat of MasterSeal 588 at 1.2 kg/m² whilst still wet. Ensure that the mesh is a minimum of 200 mm wide when treating existing cracks or joints. Second coat: Allow to cure at least 6 hours at 20°C before applying subsequent coats. Low temperatures and high humidity will delay setting and curing. Humidification of the previous coat is only allowed in extremely dry conditions. Remove eventual condensation. Brush, roll or spray the mix onto the surface in a similar thickness as above, finishing in one direction, preferably at 90° to the previous layer to ensure good coverage.

CURING

Under hot or excessive drying conditions adequate protective shielding should be foreseen. In cold, humid or unventilated areas it may be necessary to leave the application for a longer curing period. MasterSeal 588 needs to cure under air-dry circumstances. Additional heating and/or ventilation can assist proper curing. NEVER use dehumidifiers during curing periods. COVERAGE

Each square metre will require a minimum of 1.20 kg of powder per layer. The coverage rate for each layer will be strongly influenced by the roughness of the substrate. An additional 0.5 kg/m² is required when embedding BASF Approved Mesh. STORAGE

Both components should be stored under cover, clear of the ground and stacked not more than 2 pails and cans or 6 sacks high. Protect the materials from all sources of moisture and frost (+5°C). If possible store cool. Rotate stock in order not to exceed the shelf life of 12 months for pails and MasterSeal 588 Liquid and 6 months for sacks. Rolls of mesh should be stood on end. Never use solvent based paints.

CLEAN UP AND SPILLAGES

Non hardened material may be removed with water using water. OVERPAINTING

Do not overpaint MasterSeal 588 in basements or other structures where the membrane is subject to negative water pressures. HEALTH AND SAFETY

MasterSeal 588 Powder is cement based and may be irritating to the skin and eyes. Gloves and eye protection should be worn. The use of dust masks is recommended. MasterSeal 588 Liquid should not be ingested, accidental splashes of the material to the skin or eyes should be immediately washed off with clean water. In the event of prolonged irritation, seek medical advice.

Colour: Dark brown Density: Appox. 1kg/litre at 25°C Coverage: 1 - 4.5m² / litre Flashpoint: Non flammable Service temperature: -30°C to +100°C Application temperature: +5°C to 55°C Rubber content: Min 10% in the dried film VOC Nil

STANDARDS

• THE Building Regulations 1972. • DOE 23 - Damp proof courses. • DOE 77 - Adhesives used in buildings. • BRE Digest 54 - Damp proofing solid floors.

APPLICATION PROCEDURE MasterSeal 621 may be applied by brush or squeegee. All surfaces to which MasterSeal 621 is applied must be sound, stable with an even finish and free from dirt, dust, loose debris, grease etc. It may be applied to damp but not waterlogged surfaces. Hot, very dry or porous surfaces should be dampened with a priming coat before MasterSeal 621 is applied. Where subsequent coats are to be applied, the first coat must be dry. BELOW GROUND PROTECTION:

MasterSeal 621 may be applied to green concrete immediately after shuttering has been removed. Blind the first coat with clean sharp sand to afford higher dry film thickness and aid monitoring layer applications. SANDWICH MEMBRANE

Two coats to be applied at right angles, blind second coat with clean sharp sand to provide a mechanical key for top screed (minimum thickness 50mm). MasterSeal 621 membrane should marry up with D.P.C. (where applicable). WALLS WITH DAMPNESS

Remove any coatings and plaster back to the blockwork. Apply three coats MasterSeal 621 blinding the final layer with clean sharp sand whilst still tacky. Replaster using a render modified with MasterCast 141 .


CURING / DRYING

a. MasterSeal 621 will take longer to dry sufficiently for over-coating in low temperatures and high humidity.

b. Provisions of good ventilation will significantly reduce drying time.

c. When testing for watertightness by means of ponding water on the internal face, the MasterSeal 621 should be allowed to dry for 7 days.

d. Where MasterSeal 621 is not pond tested, it should be allowed to dry for 3-5 days before backfilling.

SPECIFICATION CLAUSE

MasterSeal 621: All areas indicated shall receive 2 or 3 coats as recommended of a high build rubber/ bitumen emulsion such as MasterSeal 621 as manufactured by BASF, or similar approved. EQUIPMENT CARE

Before MasterSeal 621 has dried, clean tools using soapy water. If dried, remove by scraping and with paraffin or white spirit.

STORAGE

Store under cover out of direct sunlight and protect from extremes of temperature. In tropical climates the product must be stored in an air conditioned environment. As with all bituminous emulsions, some settlement will occur with prolonged storage. It is, therefore, necessary to invert the drums every other week to disperse the settlement. Shelf life is up to 1 year in unopened containers, when stored as above. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult BASF's Technical Services Department. NOTE

Vinyl Ester Methacrylate resin for crack injection via injection hoses and packers DESCRIPTION

MasterSeal 901 is based on vinyl ester methacrylate technology. TYPICAL USES

• Injection into MasterSeal 909 hose system or directly into concrete and rock. Due to its low viscosity microcracks and capillaries can easily be filled by injection.

• In contact with water it increases its volume. This enables sealing to take place even when the crack moves. No other materials have the same characteristics.

• The expansion is dependent on the amount of water available.

• Works in a saline environment ADVANTAGES

• Good bond to damp surfaces. In contact with water no extraneous reactions take place, therefore no gas bubbles or foam layer are formed, both of which would hinder the bonding process.

• In wet and humid conditions, there is a balance between the water content of the adjacent medium and MasterSeal 901 .

• Remains expanded when concrete has a moisture content.

• The expansion of MasterSeal 901 is reversible and is unaffected by ageing or electrolytic water.

• Suitable for injection with one component or two component pumps.

PACKAGING

MasterSeal 901 is supplied in three component packages of 22.066kg and 5.522kg.

Re-injectable hose waterstop system for constructio n and cold joints in concrete DESCRIPTION

MasterSeal 909 is a blue flexible PVC hose which comprises a solid core and lateral openings covered by neoprene strips, all banded by an open webbed nylon mesh. PRIMARY USES

MasterSeal 909 is designed to replace waterbar for use in concrete structures which contain joints other than expansion joints and subject to hydrostatic pressure on one or both faces of the structure. Its use prevents passage of water through concrete joints in the following typical applications. • Water reservoirs / tanks • Canals • Dams • Sewage treatment plants • Liquid storage vessels • Any sub base concrete construction • Water excluding or retaining structures ADVANTAGES

• Eliminates costly design, welding and installation of waterbar.

• Water cannot penetrate treated joint and rebar, unlike traditional installation where water is in contact with the reinforcement up to the waterbar.

• The installed system assures a watertight structure.

• Fast easy installation procedures even to complicated design detail.

• Proven and predictable performance. • Joints can be tested for watertightness before

backfilling or membrane tanking operations. • System enables retro-injection, to stop leaks

caused subsequently by settlement or structural movement at the construction joint.

• Completely maintenance free. • Possible to retro-fit when new construction is

built against existing structures.

PACKAGING Two boxes comprising the following: Box 1 100 meters blue re-injectable hose Box 2 a) 20 meters green vent hose b) 20 meters transparent vent hose c) 2 meters shrink on sleeve d) 2 meters connecting nozzle e) 30 closure plugs f) 500 anchor clips TYPICAL PROPERTIES

MasterSeal 909 re-injectable hose is a specially formulated PVC compound. The material is tough, flexible, resilient, chemically inert, is not affected by weathering, low temperatures, or constant immersion in water. It will withstand rough treatment during installation and is easy to install. MasterSeal 909 re-injectable hose is unaffected by alkalis, sewerage, most water solutions of organic chemicals, aliphatic hydrocarbons (fuel), mineral oils, acids and alcohols. Outside diameter 19mm, longitudinal internal injection hole diameter 6mm, discharge openings diameter 3mm. Installation within all types of concrete joints. INSTALLATION

PREPARATORY WORK:

All MasterSeal 909 re-injectable hoses should be protected from oil, dirt, concrete spatter and damage and should be left clean to receive concrete. The surface where the MasterSeal 909 re-injectable hose will be installed has to be smooth. The surface generated by an internal vibrator while compacting the concrete will usually be suitable.


METHOD:

The MasterSeal 909 re-injectable hose consists of the injection hose itself and the vent ends. These are specially fabricated PVC hoses to withstand injection pressure, in green and transparent colours. The vent ends allow the fixing of injection equipment at a later stage and generally project 20 cms out of the concrete surface. After pouring the concrete, only the vent ends are visible. The different colours make the identification of the start and end of the hose after concreting. The injection hose and vent ends must be encased in at least 5cm of concrete. The MasterSeal 909 re-injectable hose is installed in lengths up to a maximum length of 12m. For upto 600 mm wall thickness the MasterSeal 909 hose should be installed at the centre of the wall thickness. The hose is clamped into position with MasterSeal 909 clips spaced about 200-250mm apart. The hose must not be fastened to the reinforcement bars in the wall. It is essential that there is a direct contact between the hose and the concrete. If aggregate or debris lie on the concrete, these must be removed, to prevent floating of the hose in the freshly poured concrete. GUIDELINES

Installation, injection, reinjection, and selection of materials should be entrusted to an experienced and certified MasterSeal 909 applicator. The injecting of the hose may be carried out at any time either before switching off the dewatering as a precautionary measure or afterwards if leaks are noticed. The hose may be injected with water under pressure to test the integrity of the joint. Injection of the MasterSeal 909 hose with MasterSeal 901 permits reinjection. Use of any other resins will render the hose unusable.

Injection always starts at one end adopting the following procedure: • Fill the hose with injection material by means

of an injection pump until it flows out at the other end.

• Plug that end with the end cap. • Pressurise the MasterSeal 909 hose. Continue to inject until the moment that no material flows into the joint (there is no or only slight pressure drop at the gauge); resin is seen flowing out of the joint or a predetermined quantity has been injected. Sealing is achieved by moderate pressure and a longer injection time, as opposed to high pressure over a brief injection period. • If required the same procedure may be

adopted from the other end of the MasterSeal 909 hose, this is to ensure even pressure distribution over the whole length.

• Within the gel time, pressurise the hose again briefly.

NOTE

Normally one injection is enough to completely seal the joint, however this depends on the quality of the concrete and/or the water pressure.

COMPONENTS OF THE MasterSeal 909 HOSE

1. Injection diameter 6mm. 2. Solid hose core for resisting concrete pressure. 3. The lateral openings with a diameter of 3mm,

each staggered by 1cm, ensure a uniform discharge of the injection material.

4. The three neoprene strips in the longitudinal grooves act as non return valves.

Water swelling waterbar for joints DESCRIPTION

MasterSeal 910 Waterbar is suitable for all construction joints subject to hydrostatic pressure, on one or both sides. MasterSeal 910 provide simple but efficient waterproofing of construction joints. Movements in the joint, e.g. by shrinkage or settlement in the substrate, are taken up by the elastic profile of the MasterSeal 910 Waterbar. MasterSeal 910 has been successfully employed to waterproof joints where an opening of up to 5mm was deliberately created. Water pressure of up to 5 bar was sealed. MasterSeal 910 is a component of the BASF pile-cap waterproofing and watertight jointing systems. Consult your representative for details.

MasterSeal 910 is based on a newly developed polymer technology providing flexible polymer composites which have high chemical resistance capable of storing water in their molecular structure by increasing their volume. Where previously MasterSeal 910 was available in different grades for various exposure conditions. A single version of MasterSeal 910 now resists deterioration in the following conditions: In fresh water and where the water has a high salt content (sea water, brackish water), in construction with high chemical exposure and/or exposure of solvents, including oils and fuels. FUNCTIONAL BEHAVIOUR

When in contact with water the MasterSeal 910 Waterbars will slowly increase in volume (swell) without changing the homogeneous structure of the polymer matrix. The increase in volume by the swelling action can be up to 200% (depending on type of water). The pressure of the swelling action will cause the MasterSeal 910 Waterbar to profile itself exactly into the joint filling all cavities and effectively stopping water seepage, even at high external water pressure. The MasterSeal 910 Waterbars will not transport water through their polymer matrix and thus not act as a capillary duct. The swelling action is limited to the sides exposed to water.

PACKAGING 20 x 10mm (± 5%) 30 linear metres per carton. INSTALLATION PROCEDURE

PREPARATION:

All joints to be waterproofed with MasterSeal 910 Waterbars must first be cleaned. Free standing water and sharp protrusions must be avoided. MasterSeal 910 Waterbars can be installed on moist or frozen surfaces. MasterSeal 910 Waterbars are resistant to most ordinary mould release agents, but if in doubt the installed waterbar should always be protected from accidental exposure to form release agents. PLACING:

For normal joint widths of 200-400mm, MasterSeal 910 is placed in the middle of the joint. For added safety thicker walls can be fitted with 2 waterbars. MasterSeal 910 Waterbars are glued into the joint with a special adhesive for MasterSeal 910 Waterbars. On vertical surfaces the MasterSeal 910 is temporarily fixed to the construction joint with a nail until the adhesive dries. MasterSeal 910 Waterbar MUST always be secured so that the waterbar is in close contact with the surface of the substrate otherwise the full waterproofing effect will not be obtained. After placing the MasterSeal 910 Waterbar the joint area should be kept clean and free of loose dirt and stones before concreting. The minimum concrete cover of MasterSeal 910 Waterbar is 80mm.

CHEMICAL RESISTANCE

MasterSeal 914 resists non-oxidising mineral acids and salts, caustics, dilute oxidising acids and salts, plus some organic acids and solvents. For more specific information contact your BASF Representative. CURE TIME VS. TEMPERATURE

Cure time of the mortar will depend upon the temperature of the base and foundation rather than the ambient air temperature. Unless the ambient air temperature has been constant for several days the base / foundation temperature will generally be lower than air temperature. A surface thermometer and field judgement should be used to a determine actual cure rates. Cured grout should have solid, almost metallic ring when struck lightly with a hammer, checking as close to the base as possible. APPLICATION THICKNESS

MasterSeal 914 can be used for thick section applications. The following procedures briefly describe the installation of MasterSeal 914:


CONCRETE PREPARATION & SEALING


As with all epoxy resin applications the quality of surface preparation has a direct effect on the performance and durability of the system. Concrete surfaces should be sound, dimensionally stable, clean, free from laitance, paint, oil, grease, mould release agent and residual curing compound. The concrete surface must be scabbled so that large aggregate is exposed to ensure removal of all laitance and weak surface material. New concrete should have a compressive strength of at least 25 MPa; greater strength is preferred. THE CONCRETE SURFACE MUST BE CLEAN AND DRY WHEN THE GROUT IS POURED. The concrete areas to be grouted should not be primed or sealed. Do not apply MasterSeal 914 when the contact surfaces are less than 10°C. If the ambient temperature is less than 10°C then artificial heating may be used. In summer weather shade host concrete from direct sunlight. MIXING

Do not split packs or alter the ratio of resin components in any way. Mix with a slow speed drill and paddle. Add the contents of the reactor container to the base component in a suitable mixing vessel, ensuring complete transfer of both resin components. Mix for one minute before slowly adding the aggregate and continue mixing until a pourable consistency is achieved. Do not overmix as this may entrain air. METAL PREPARATION AND PRIMING

Metal surfaces or components to be bedded, should be free from any rust or scaling. Base plates or rails and other metal surfaces to be grouted should be cleaned to obtain proper adhesion. This is preferably done just prior to grouting. Primer should be used ONLY when a long delay between cleaning and grouting will allow rusting or contamination. Surfaces where a bond is not desired should be protected with heavy coats of wax.

FORMING

MasterSeal 914 requires forms. Forms are generally wood, the same as used for forming concrete. They should be of sufficient strength, anchored or braced to withstand pressure from the grout and must be liquid tight. Wrapping forms in polyethelene will ensure clean release. PLACING

Place immediately after mixing, into the prepared area and use a steel trowel to level. 90-180 min at 10°C Allow the grout to set prior to removal of formwork (normally after 6 hours). WORKING TIME

The following chart is a guide for the working time of a fresh grout mix at various ambient temperatures. The working time of a MasterSeal 914 mix begins when the hardener is added to the liquid. 40-60 min at 35°C 50-100 min at 20°C STORAGE

Store under cover, out of direct sunlight, and protect from extremes of temperature. In tropical climates the product must be stored in an air conditioned environment. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult BASF's Technical Services Department.

As with all epoxy resin applications the quality of surface preparation has a direct effect on the performance and durability of the system. Concrete surfaces should be sound, dimensionally stable, clean, free from laitance, paint, oil, grease, mould release agent and residual curing compound. The concrete surface must be chipped so that large aggregate is exposed to ensure removal of all laitance and weak surface material. New concrete should have a compressive strength of at least 25 MPa; greater strength is preferred. THE CONCRETE SURFACE MUST BE CLEAN AND DRY WHEN THE GROUT IS POURED. The concrete areas to be grouted should not be primed or sealed.

MIXING

Do not split packs or alter the ratio of resin components in any way. Mix with a slow speed drill and paddle. Add the contents of the reactor container to the base component in a suitable mixing vessel, ensuring complete transfer of both resin components. Mix for one minute before slowly adding the aggregate and continue mixing until a flowing, pourable consistency is achieved. Do not overmix as this may entrain air. Ungrouted exposed concrete surfaces may be sealed to prevent oil penetration. METAL PREPARATION AND PRIMING

Metal surfaces or components to be bedded, should be free from any rust or scaling. Base plates or rails and other metal surfaces to be grouted should be cleaned to obtain proper adhesion. This is preferably done just prior to grouting. Primer should be used ONLY when a long delay between cleaning and grouting will allow rusting or contamination. Surfaces where a bond is not desired should be protected with heavy coats of wax. FORMING

MasterSeal 915 is fluid and requires forms. Forms are generally wood, the same as used for forming concrete. They should be of sufficient strength, anchored or braced to withstand pressure from the grout and must be liquid tight. Wrapping forms in polyethelene will ensure clean release. PLACING

Place immediately after mixing, into the prepared area in such a manner that it has the shortest distance to flow. For longer pours a suitable head of pressure may be required. Ensure the area to be grouted is not completely sealed, and any displaced air can be expelled. Pour continuously from one end only. Allow the grout to set prior to removal of formwork (normally after 6 hours).

FINISHING AND CLEAN UP

A smooth finish may be obtained by spraying or brushing the surface with MasterTop THN 2 approximately 1 hour after the grout is poured. Best results can be obtained by smoothing the surface several times just prior to the hardening of the grout surface. Clean tools and mixer with MasterTop THN 2. Do not apply MasterSeal 915 when the contact surfaces are less than 10°C. If the ambient temperature is less than 10°C then artificial heating may be used. WORKING TIME

Sealing tape for irregular and unconventional joint s

DESCRIPTION MasterSeal joint sealing system consists of two products MasterSeal 930 and MasterBrace ADH 2200 epoxy. The MasterSeal 930 is a highly elastic, rot-proof and chemically resistant sealing membrane. MasterBrace ADH 2200 is a two part epoxy compound which establishes a strong bond to various types of substrate.

FIELDS OF APPLICATION Sealing of construction joints, expansion joints, connecting joints, cracks and crevices, etc. Adheres to many types of substrate such as concrete, mortar, plaster work, steel iron, aluminum, stoneware, glass and epoxy. Typical uses are for concrete tanks, cast and cement-pipe connections, bridge decks, tunnels, water towers and reservoirs, ponds, silos, containers, secondary tanks. MasterSeal 930 can be applied on dry or slightly humid substrates. It is ideal for joints with very large expansion or irregular, broken joint flanks. MasterSeal 930 , is Grey coloured, weather and waterproof.

BENEFITS • Durable

• Long lasting elasticity, even at high temperatures

• Root resistant

• Resistant to a wide range of chemicals

• Cost effective

• Approved for use with potable water

• Easy to apply

• User friendly heat welding of tape overlaps

• Can be applied horizontally, vertically and even overhead.

APPLICATION

SURFACE PREPARATION Contact surfaces must be clean and free from dust, grease, water, oil, and other contaminants impairing adhesion. Concrete should be at least 4 weeks old. In order to provide maximum adhesion, concrete surfaces should be mechanically abraded.

APPLICATION Mix MasterBrace ADH 2200 adhesive thoroughly, following the guidelines of the manufacturer. Apply the well-mixed MasterBrace ADH 2200 on both sides along the joint or crack on the prepared substrate, preferably with a notched trowel or spatula. Layer thickness should be about 1-2 mm. When sealing cracks, or narrow joints the MasterSeal 930 should not be bonded along the centre line of the tape. A minimum unbonded width of 20mm is recommended to allow for expansion and contraction. Wipe the edges of the tape with MasterTop THN 2 , then place the clean and well-aired tape immediately into the adhesive layer and press well in with a roller. For very wide joints draw the tape suitably into the joint so that a hollow is formed. Holes punched at the edges provide added anchorage. By warming up the membrane, it can be stretched over slight irregularities of the substrate. The same method can be used in case of corners, cavities, pipe crossing. If individual tapes have to be connected into longer pieces (also T-pieces, etc.) they can easily be welded using a hot air blower. In case of negative water pressure (more than 0.3 bar) back up the membrane with an adequate support, e.g. steel sheet, etc., in particular if joints are subject to large movement.

MasterSeal ® 940 (Formerly known as Masterflex Aquastop)

Centrally and externally placed PVC Waterstops DESCRIPTION

MasterSeal 940 is a range of centrally placed and externally placed PVC Waterstops extruded from high grade PVC compound. PRIMARY USES

MasterSeal 940 is designed to provide a complete sealing network for expansion and contraction/ construction joints in water retaining and water excluding in-situ concrete structures. The profiles are supplied in straight lengths to be butt jointed on site. Factory made intersections are available for complex junctions. The use of MasterSeal 940 prevents the passage of water through expansion/ contraction/ construction joints in the following typical structures: • Canals/ culverts • Water tanks • Reservoirs • Dams • Sewerage Treatment Plants • Liquid retaining vessels • All cast in-situ concrete structures to retain

or exclude water ADVANTAGES

• Complete range of profiles and sizes to suit all construction requirements.

• Reinforced eyeleted fixing flanges on centrally placed profiles for positive location in joints prevents collapse of profile during concrete placing.

• Simple on-site butt welding. • Four valve sealing system on all profiles. • Premoulded intersection/ junction pieces

available. DESIGN CONSIDERATIONS

PVC Waterstops were originally designed as simple dumbbell profiles which worked on the valve sealing action of the opening joint putting the waterstop in tension, thus sealing the water path. Later designs included multi ribs and fins, in what is known as the tortuous path principal of an extended potential water track created by the ribs and fins.

MasterSeal 940 combines all the accepted and proven principals of PVC Waterstop in four valve and tortuous path design, together with reinforced eyeleted fixing flanges on all centrally placed profiles plus grout check fins on all construction/ contraction joint profiles. TYPICAL PROPERTIES*

Shear) PROFILES

Centrally placed MasterSeal 940 profiles provide a barrier across all joints in-situ concrete structures by casting the section centrally into the edges of adjacent concrete components. Used in most water retaining and water excluding structures, they are capable of withstanding water pressure from either the internal or external face.


MasterSeal 940 IEJ

(Internal Expansion Joints): Expansion bulb sections principally for expansion joints but can be used for construction/ contraction joints. With reinforced eyeleted fixing flanges for wiring the waterstop to surrounding rebar.

MasterSeal 940 ICJ

(Internal Construction/ Contraction Joints): Plain web sections for construction/ contraction joints, also with reinforced eyeleted flanges and grout check fins to prevent grout loss from formwork.

Externally placed MasterSeal 940 profiles are principally designed for basement, foundation and floor slab applications in both vertical and horizontal joints.

Each externally placed section incorporates a reinforced railing flange for fixing to the formwork or blinding concrete. The four valves allow good concrete compaction and very secure anchorage into the concrete. MasterSeal 940 EEJ

(External Expansion Joints): Sections have a flat top, wedged expansion box for positive anchorage and good seating of joint fillers. EEJ sections can also be used in construction/ contraction joints. The bottom web in the expansion box is thinned to cater for excessive subsidence or seismic movement should it occur.

MasterSeal 940 ECJ

(External Construction / Contraction Joints): Sections are plain web incorporating grout check fins to prevent grout loss at formwork.


SPECIAL PROFILES

MasterSeal 940 200M ICJ/E is an economic construction/ contraction joint profile specifically for use in kicker and contraction joints in small structures such as water tanks cast in-situ manholes, channels etc where there are no expansion joints and wall or slab thicknesses do not exceed 200mm.Includes an eyeleted flange.

MasterSeal 940 250 ICJ/X & 250IEJ/X

Are10mm thick web profiles for applications where there is high water pressure or head of water in excess of 70meters. Both profiles include reinforced eyeleted fixing flanges and are compatible with 250 ECJ/ EEJ profiles in an integral network.

WATERSTOP SELECTION

MasterSeal 940 PVC Waterstops are designed for use within the performance parameters indicated under the headings Technical Data and Typical Properties. Centrally placed profiles (ICJ & IEJ) are usually located midway in the slab or wall thickness across the joints in concrete structures. They will equally prevent the passage of water through the joint from either face. They are particularly suited to water retaining structures and in walls and slabs where pressure differential may occur such as in reservoir walls. They are equally appropriate for joints in suspended slabs, vertical wall joints and lift joints.

Externally placed profiles (ECJ & EEJ) are of particular advantage for their ease of installation in basement and foundation applications in situations where they are firmly supported against back pressure, i.e. in water retaining structures (base slab) where they are placed on the blinding concrete. SIZE OF WATERSTOP

The choice of width of profile is mainly governed by slab/ wall thickness, position of reinforcing steel and aggregate size. As a general rule, the 250mm width profiles are appropriate for slab/ wall thickness over 250mm, allowing good compaction and width of barrier to water penetration. For concrete members less than 250 mm the use of a smaller profile approximating to the actual slab or wall thickness will be appropriate. INSTALLATION

MasterSeal 940 ICJ & IEJ profiles must be installed so they are securely held in the correct position whilst the concrete is poured. The concrete must be fully and properly compacted around the waterstops (the use of BASF’s Rheodynamic admixtures to produce self compacting concrete is of great advantage to avoid voids or porous areas after concrete placing). Where reinforcement is present, an adequate clearance must be left between this and all waterstops to permit proper compaction of the concrete.


The eyelets in the reinforced flanges of the ICJ and IEJ profiles allow them to be wired to the surrounding reinforcing steel. The eyelets are an integral part of the profiles and being placed outside the outer valves cannot create a water path around the profile or impair the efficiency in performance in any way. See typical detail below.

MasterSeal 940 ECJ & EEJ profiles when used on ground slab blinding concrete where a permanent, firm and stable support is given usually require no fixing. The profile is simply laid centrally over the line of the joint to be formed. Fixing to vertical shuttering is simplified by nailing with double headed nails through the outer reinforced flange to provide a firm fixing as shown below.

EQUIPMENT

Heat welding equipment is required to enable site jointing to be carried out efficiently. Jointing jigs ensure that the mating surfaces of the waterstop are accurately aligned while the heater blade heats the waterstop to the necessary temperature for jointing. 220 Volt Electric Heater Blades are recommended for use with all jigs. SITE JOINTING INSTRUCTIONS

Reliable jointing of MASTERRLEX AQUASTOP waterstops can be carried out rapidly onsite with appropriate heat welding equipment. HEAT WELDING OF WATERSTOPS

Make sure that the heater blade is clean, plug it into the correct voltage electricity supply and leave in a safe position to warm up. Ensure that the ends of the waterstop to be jointed are of the same width and profile; clean them with water or MasterTop THN 2 and dry them. Clamp them in the correct profile slots of the jig provided and cut both ends off square with a sharp knife, flush with the faces of the jig. Note: An allowance must be made for waste and for the 5 to 10mm that will be taken up by melting when calculating the length of waterstop required. Loosen the jig and slide them back so that approximately 10mm of each waterstop end projects and then clamp the jig tightly in position. Position the heater blade on the bars between the jigs and slide them together until the waterstop ends are pressed firmly against the sides of the blade. The PVC should melt without burning or charring. Hold the jig firmly in position until a bead of molten PVC approximately 3mm in diameter appears along either side of the heater blade.


Slide the jig apart a little and remove the heater blade with an upward movement. This will ensure that it takes as little PVC as possible with it. Quickly joint the molten ends by sliding the jig together and exerting pressure. Approximately 20 seconds to allow the molten PVC to fuse completely. Switch off the heater blade. While it is still hot, clean thoroughly with emery paper or a wire brush ready for the next joint. Unclamp the jig and carefully remove the waterstop. Do not flex the joint until it has cooled. The joint is now complete. When cold, test it by flexing the waterstop several times. INERSECTION PIECES

All tests carried out at 20°C; samples cured for 28 days at 20°C APPLICATION

Substrate quality: All substrates must be clean and free from dust and loose particles. Concrete and other cementitious substrates must be dry (maximum moisture content 4% by CM test method). All traces of contaminants, such as oils, fats, greases, paint residues, chemicals, algae and laitance, should be removed. Steel and iron substrates must be free of rust and mill scale. Preparation of substrate: As with all surface coatings, proper surface preparation is vital to ensure the successful application and performance of MasterSeal CR 460. For practical reasons, surface preparation methods will be limited to sand blasting or grinding. Wire brushing can be used but only where other methods are impracticable. Remove all dust by vacuum. Ensure free movement of the joint by installing a joint backing rod or debonding tape. These are normally closed-cell expanded polyethylene rods.


MIXING MasterSeal P 460 Mix the two components at the supplied ratio using a slow speed stirrer (approximately 400rpm). Care should be taken to mix in any material sticking to the walls of the container. MasterSeal CR 460 Use complete units only. Using a slow speed stirrer (approximately 400rpm) mix the contents of the Part 1 pail for 30 seconds to re-disperse any separated material. Add the contents of the Part 2 can and mix for a further 1 to 2 minutes. Do not mix excessively as this traps air within the mix. Ensure that no undispersed Part 1 is left on the side of the pail. Application: The application temperature must be between 5°C and 40°C. The substrate temperature should be at least 3°C above the dew point. Do not apply if condensation is likely to occur before full cure occurs. Failure to observe these conditions will result in failure or a poor quality job. • Apply MasterSeal P 460 to the substrate

using a brush. A thin layer (± 100µm) should be applied to the joint edges.

• While the MasterSeal P 460 is still tacky (30 minutes to 2 hours, depending on the temperature) pour in the mixed MasterSeal CR 460 to fill the joint flush to the surface. Use a spatula to remove trapped air. MASTERFLEX 460 can be applied on angled surfaces up to 2% without slumping.

If the MasterSeal P 460 has become tack-free, a second coat should be applied before pouring the MasterSeal CR 460 to ensure proper bonding. CURING

MasterSeal CR 460 has limited resistance to concentrated mineral and organic acids and alkalis. It is also attacked by aggressive organic solvents such as xylene and acetone but in practice many such solvents evaporate rapidly and cause little damage. Extensive chemical resistance tables are available on request. For detailed information please contact your local BASF Construction Chemicals office for guidance. CLEANING

Cleaning of plant and equipment should be undertaken well away from the application area. Xylene may be used to clean equipment, tools and spillages. In the case of spillages, excess material must first be absorbed onto sawdust or other disposable absorbent medium. Use correct handling procedures with solvents and take care to avoid any accidental spillage or splashes onto coated surfaces. Part 2 containers may contain small amounts of unreacted diisocyanates (MDI). Therefore they must be decontaminated with a 5% solution of soda ash (sodium carbonate or washing soda) prior to disposal as building waste. MAINTENANCE

Regular cleaning and prompt clean up chemical spillages will prolong the life of all joint sealants. Specialised floor cleaning equipment and chemicals are widely available and the suppliers are able to offer advice on appropriate cleaning regimes. Consult them or your local BASF office for details. STORAGE

MasterSeal CR 460 and MasterSeal P 460 should be stored under cover and clear off the ground. Storage conditions should be dry, above 5°C and below 30°C. Upon storage some sedimentation of the Part 1 component may occur; this will be readily dispersed during mixing and has no effect on the product’s performance.

SHELF LIFE Minimum 12 months when stored as recommended in unopened containers. HEALTH AND SAFETY

Appropriate health and safety advice can be found in the Material Safety Data Sheets. Users are advised to wear gloves and eye protection when mixing and applying MasterSeal P 460 and MasterSeal CR 460 . SAFETY PRECAUTIONS

As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapour until products is fully cured or dried). Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Reseal containers after use and dispose off empty containers correctly. NOTE

surfaces. 10mm for all porous surfaces. 20mm for joints exposed to hydrostatic

pressures. 5mm below flush for joints exposed to traffic. APPLICATION PROCEDURE

JOINT PREPARATION SURFACE TREATMENT

Concrete & Masonry

Surfaces must be clean and dry. Wire brush thoroughly and remove dust and all contaminants.

Metals Remove any corrosion or millscale by grit or shotblast, wirebrush, grinder or chemical remover. De-grease the surfaces with clean cloths soaked in oil-free cleansing solvent.

Wood (bare) Wood surfaces must be clean and dry, cut back or abrade where necessary to sound timber.

Glass and glazed materials

Thoroughly clean the surfaces with clean cloths soaked in oil-free cleansing solvent.

Coating surfaces

Coating should be removed and the surfaces treated as above.

Where required, a bond breaking tape should be applied before priming.


PRIMING

The correct primer must always be used. SURFACE APPLICATION

MasterSeal P 101 Porous surfaces (such as concrete and masonry) Non-porous surfaces (such as metals, glass and glazed surfaces). Application of primer should not be carried out

below 4°C. A single coat of primer should be applied by

brush in accordance with the instructions on the primer tins. The primer must be allowed to dry to a tack free state before applying MasterSeal GG 470.

MasterSeal GG 470 should be applied within 3 hours of primer, otherwise repriming will be necessary.

APPLICATION TEMPERATURE

MasterSeal GG 470 should be applied when the ambient temperature is between 4°C and 50°C. When the temperature is below 10°C storage at room temperature for several hours will ease mixing and application. APPLICATION TEMPERATURE

MIXING:

Mix and use one complete unit at a time. Do

not sub-divide. Gun grade is supplied in base & catalyst in

separate units. Mix for 5 - 10 minutes using a suitable paddle

fitted to a 500 rpm electric drill moving the paddle completely through the mass of the material.

Add the complete contents of the catalyst from its container and mix thoroughly, into the base using a palette knife.

Failure to completely disperse catalyst throughout the base compound will result in uncured sealant. Once mixed MasterSeal GG 470 should be used immediately.

APPLICATION

MasterSeal GG 470 is formulated to be applied using a sealant gun but may be applied by trowel if required.

Sealant guns are fitted with conical nozzles which can be cut to suit the joint width.

The sealant should be gunned into the joint using an even trigger pressure, cleaning the nozzle occasionally to avoid contamination. Deep joints should be filled in two or more runs, to prevent air entrapment.

Once the sealant has been applied, a small timber spatula, soaked in soapy water, should be used to compact the sealant into the joints and to achieve a smooth polished finish. Any masking tape which has been applied should be removed before the sealant cures.

Mixing and application equipment should be cleaned immediately. COVERAGE

How to apply: JOINT PREPARATION

1. The product may be used in sealant joints designed in accordance with SWR Institute's Sealants - The Professional's Guide.

2. In optimal conditions, the depth of the sealant should be ½ the width of the joint. The sealant joint depth (measured at the center) should always fall between the maximum depth of 12mm and the minimum depth of 6mm. Maximum recommended joint width is 75mm. Refer to Table 1.

Joint Width, (mm) Sealant depth at midpoint, (mm) 6-13 6 13-19 6-10 19-25 10-13 25-75 13


3. In deep joints, the sealant depth must be controlled by closed cell backer rod or soft backer rod. Where the joint depth does not permit the use of backer rod, a bond breaker (polyethylene strip) must be used to prevent three-point bonding. 4. To maintain the recommended sealant depth, install backer rod by compressing and rolling it into the joint channel without stretching it lengthwise. Closed cell backer rod should be about 3mm larger in diameter than the width of the joint to allow for compression. Soft backer rod should be approximately 25% larger in diameter than the joint width. The sealant does not adhere to it, and no separate bond breaker is required. Do not prime or puncture the backer rod. SURFACE PREPARATION

Substrates must be structurally sound, fully cured, dry and clean. Substrates should always be free of the following: dirt, loose particles, oil, grease, asphalt, tar, paint, wax, rust, waterproofing or curing and parting compounds, membrane materials and sealant residue. CONCRETE, STONE, AND OTHER MASONRY Clean by grinding, sandblasting or wire brushing to expose a sound surface free of contamination and laitance. WOOD New and weathered wood must be clean, dry and sound. Scrape away loose paint to bare wood. Any coatings on wood must be tested to verify adhesion of sealant or to determine an appropriate primer. METAL Remove scale, rust and loose coatings from metal to expose a bright white surface. Any coatings on metal must be tested to verify adhesion of sealant or to determine an appropriate primer. PRIMING

1. MasterSeal NP 2 is generally considered a non-priming sealant, but special circumstances or substrates (e.g., certain protective coatings on aluminium) may require a primer. It is the user’s responsibility to check the adhesion of the cured

sealant on typical test joints at the project site before and during application. Refer to Technical Data Guide on MasterSeal P 173, and consult BASF Technical Services for additional information. 2. Apply primer at full strength with a brush or clean cloth. A light, uniform coating is sufficient for most surfaces. Porous surfaces require more primer, however, do not over-apply. 3. Allow primer to dry before applying MasterSeal NP 2. 4. Depending on temperature and humidity, primer will be tack free in 15 to 120 minutes. Priming and sealing must be done on the same work day. MIXING

1. MasterSeal NP 2 is a multi-component system with a configuration of Part A, Part B and a color pack. 2. Transfer entire contents of Part B to Part A container using a spatula or margin trowel. 3. Part B must be mixed thoroughly with Part A. Before adding pigment, scrape sides of container to ensure complete mixing of Parts A and B. With a slow-speed drill and a sealant mixing paddle, mix 4–6 minutes. Keep the paddle blade below the surface of the sealant to avoid whipping air into the sealant. 4. Transfer the entire contents of one MasterSeal 900 pigment can into the mixed Part A and B. Use a spatula or knife to remove all the pigment from the container. Continue mixing with a slow-speed drill and slotted paddle until color is uniform. During the process, scrape the sides and bottom of the mixing container several times to obtain a complete mix. APPLICATION

Except when unusual job conditions dictate the use of knife or spatula, apply MasterSeal NP 2 by professional bulk gun loaded at the jobsite. Fill joints from the bottom up to the exterior face by holding a properly sized nozzle against the joint bottom. Dry tooling is recommended. Proper tooling results in the correct bead shape, neat joints, and optimal adhesion. Best practices dictate that all caulking and sealing be done when temperatures are above 40°F (4°C) to avoid application to moisture-laden


surfaces. Moisture on substrates will adversely affect adhesion. Application may proceed as low as 40°F (4°C) if there is certainty that substrates are completely dry, free of moisture and clean as described under Surface Preparation. CURING

The cure of MasterSeal NP 2 varies with temperature and humidity. The following times assume 75°F (24°C), 50% relative humidity, and a joint 13mm in width by 6mm in depth. – Skins: within 3–4 hours – Full cure: approximately 1 week See Table 2 for use of MasterSeal 905 accelerator. CLEAN UP

Immediately after use and before sealant has cured, clean equipment with MasterTop THN 2. Cured sealant may be removed by cutting with a sharp-edged tool. Remove thin films by abrading. FOR BEST PERFORMANCE

Pursuant to accepted industry standards and practices, using rigid paints and/or coatings over flexible sealants can result in a loss of adhesion of the applied paint and/or coating, due to the potential movement of the sealant. However, should painting and/or coating be desired, it is required that the applicator of the paint and/or coating conduct on-site testing to determine compatibility and adhesion.

Do not allow uncured MasterSeal NP 2 to come into contact with alcohol-based materials or solvents.

Do not use as a cap, heel or toe bead for exterior glazing.

Do not apply polyurethane sealants in the vicinity of uncured silicone sealants or uncured MasterSeal NP 150.

MasterSeal NP 2 should not come in contact with oil-based caulking, silicone sealants, polysulfides or fillers impregnated with oil, asphalt or tar.

Do not apply epoxy-based coatings in the vicinity of uncured MasterSeal NP 2.

Do not apply to freshly treated wood; treated wood must have weathered for at least 6 months.

Do not open containers until ready for use. Units are premeasured; do not use partial

units. MasterSeal NP 2 may yellow in the

presence of unvented artificial heat; this is a surface phenomenon that does not affect sealant performance.

When MasterSeal NP 2 is used in areas subject to continuous water immersion, cure for 14 days at 70°F (23°C). Allow longer cure times at lower temperatures. Always use Master Seal P 173.

Do not use in swimming pools, or on other submerged conditions where the sealant will be exposed to strong oxidizers. Avoid submerged conditions where water temperatures will exceed 120°F (50°C).

Horizontal joints subject to traffic or intermittent ponding of water require the use of primer. Call Technical Service for details.

Substrates such as copper, stainless and galvanized steel typically require the use of a primer; MasterSeal P 173 or MasterSeal P 176 are acceptable. For Kynar coatings, use MasterSeal P 173 only. An adhesion test is recommended for any other questionable substrate.

Use only MasterSeal 900 color packs designed for use with MasterSeal NP 2.

Proper application is the responsibility of the user. Field visits by BASF personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the jobsite.

How to apply:

JOINT PREPARATION 1. The product may be used in sealant joints designed in accordance with SWR Institute's Sealants - The Professional's Guide. 2. In optimal conditions, the depth of the sealant should be ½ the width of the joint. The sealant joint depth (measured at the center) should always fall between the maximum depth of 12mm and the minimum depth of 6mm. Maximum recommended joint width is 75mm. Refer to Table 1. 3. In deep joints, the sealant depth must be controlled by closed cell backer rod or soft

backer rod. Where the joint depth does not permit the use of backer rod, a bond breaker (polyethylene strip) must be used to prevent three-point bonding. 4. To maintain the recommended sealant depth, install backer rod by compressing and rolling it into the joint channel without stretching it lengthwise. Closed cell backer rod should be about 3mm larger in diameter than the width of the joint to allow for compression. Soft backer rod should be approximately 25% larger in diameter than the joint width. The sealant does not adhere to it, and no separate bond breaker is


required. Do not prime or puncture the backer rod. SURFACE PREPARATION

Substrates must be structurally sound, fully cured, dry and clean. Substrates should always be free of the following: dirt, loose particles, oil, grease, asphalt, tar, paint, wax, rust, waterproofing or curing and parting compounds, membrane materials and sealant residue. EIFS 1. MasterSeal NP 150 should be applied to the system base coat for best adhesion and to avoid delamination of EIFS finish applied in the joint. 2. Base coat must be sound, well bonded, properly cured and of sufficient depth to comply with manufacturer’s specifications. 3. Certain EIFS systems require the use of a primer. Refer to the EIFS manufacturer for recommendations. CONCRETE, STONE, AND OTHER MASONRY Clean by grinding, sandblasting or wire brushing to expose a sound surface free of contamination and laitance. WOOD New and weathered wood must be clean, dry and sound. Scrape away loose paint to bare wood. Any coatings on wood must be tested to verify adhesion of sealant or to determine an appropriate primer. METAL Remove scale, rust and loose coatings from metal to expose a bright white surface. Any coatings on metal must be tested to verify adhesion of sealant or to determine an appropriate primer.

PRIMING

1. MasterSeal NP 150 is generally a non-priming sealant, but special circumstances or substrates may require a primer. Porous materials subject to intermittent

water immersion require priming. Use MasterSeal P 179.

Certain architectural metal finishes may require priming with MasterSeal P 173.

It is the user’s responsibility to check the adhesion of the cured sealant on typical test joints at the project site before and during application. Refer to the technical data guides for MasterSeal P 179 and MasterSeal P 173.

2. Apply primer full strength with a brush or clean cloth. A light, uniform coating is sufficient for most surfaces. Very porous surfaces may require a second coat of MasterSeal P 179; however, do not over apply. 3. Allow primer to dry before applying MasterSeal NP 150. Depending on temperature and humidity, primer will be tack-free in 15–30 minutes. Priming and sealing must be done on the same day. APPLICATION

1. MasterSeal NP 150 comes ready to use. Apply using professional grade caulking gun. Do not open cartridges, ProPaks or pails until preparatory work has been completed. 2. Fill joints from the deepest point to the surface by holding an appropriately sized nozzle against the back of the joint. 3. Dry tooling is recommended. Proper tooling results in the correct bead shape, neat joints, and optimal adhesion. – Skins: within 3–4 hours – Full cure: approximately 1 week See Table 2 for use of MasterSeal 905 accelerator.

CLEAN UP 1. Immediately after use, clean equipment with MasterTop THN 2. Use proper precautions when handling solvents. 2. Remove cured sealant by cutting with a sharp-edged tool. 3. Remove thin films by abrading. FOR BEST PERFORMANCE

In cold weather, store container at room temperature for at least 24 hours before using.

Not for use in glazing applications. Do not apply on glass and plastic glazing panels.

For proper sealing of joint edges, all window covers must be removed prior to application or sealant.

Do not allow uncured MasterSeal NP 150 to come into contact with alcohol-based materials or solvents.

MasterSeal NP 150 should not be applied adjacent to other uncured sealants and certain petroleum based products.

MasterSeal NP 150 can adhere to other residual sealants in restoration applications. For best results, always clean the joint as advised in the Surface Preparation section of this data guide.

A product field adhesion test for MasterSeal NP 150 within the specific application is always recommended to confirm adhesion and suitability of the application.

MasterSeal NP 150 should not be used for continuous immersion in water. Contact Technical Service for recommendations.

Do not apply over freshly treated wood. Allow six months for weathering.

Do not use MasterSeal P 179 on nonporous surfaces such as aluminum, steel, vinyl or Kynar 500 based paints. Use MasterSeal P 173 on coated metals when testing dictates.

Lower temperatures and humidity will extend curing times.

MasterSeal NP 150 can be painted over after a thin film or skin forms on the surface.

Pursuant to accepted industry standards and practices, using rigid paints and/or coatings over flexible sealants can result in a loss of adhesion of the applied paint and/or coating, due to the potential movement of the sealant.

However, should painting and/or coating be desired it is required that the applicator of the paint and/or coating conduct on-site testing to determine compatibility and adhesion.

surfaces. • 10mm for all porous surfaces. • 20mm for joints exposed to hydrostatic

pressures. • 5mm below flush for joints exposed to traffic. APPLICATION PROCEDURE

JOINT PREPARATION SURFACE TREATMENT:

Concrete & Masonry

Surfaces must be clean and dry. Wire brush thoroughly and remove dust and all contaminants.

Metals Remove any corrosion or millscale by grit or shotblast, wirebrush, grinder or chemical remover. De-grease the surfaces with clean cloths soaked in oil-free cleansing solvent.

Wood (bare) Wood surfaces must be clean and dry, cut back or abrade where necessary to sound timber.

Glass and glazed materials

Thoroughly clean the surfaces with clean cloths soaked in oil-free cleansing solvent.

Coating surfaces

Coating should be removed and the surfaces treated as above.

Where required, a bond breaking tape should be applied before priming. PRIMING:

The correct primer must always be used.


SURFACE APPLICATION:

MasterSeal P 101 Porous surfaces (such as concrete and masonry) Non-porous surfaces (such as metals, glass and glazed surfaces). • Application of primer should not be carried out

below 4°C. • A single coat of primer should be applied by

brush in accordance with the instructions on the primer tins. The primer must be allowed to dry to a tack free state before applying MasterSeal PG 470.

• MasterSeal PG 470 should be applied within 3 hours of primer, otherwise repriming will be necessary.

APPLICATION TEMPERATURE:

MasterSeal PG 470 should be applied when the ambient temperature is between 4°C and 50°C. When the temperature is below 10°C storage at room temperature for several hours will ease mixing and application.

Mixing MasterSeal PG 470: • Mix and use one complete unit at a time. Do

not sub-divide. • Pouring grade is supplied in separate base &

catalyst units. • Sometimes slight settlement may occur in the

catalyst, mix well, before adding to the base component.

• Mix for 5 - 10 minutes using a suitable paddle fitted to a 500 rpm electric drill moving the paddle completely through the mass of the material. The sides and base of the container should be periodically scraped down with a palette knife to ensure all of the catalyst is completely blended with the base compound.

• Failure to completely disperse catalyst throughout the base compound will result in uncured sealant. Once mixed MasterSeal PG 470 should be used immediately.

APPLICATION:

• MasterSeal PG 470 is formulated to be applied using a sealant gun but may be applied by trowel if required.

• Sealant guns are fitted with conical nozzles which can be cut to suit the joint width. The sealant should be gunned into the joint using an even trigger pressure, cleaning the nozzle occasionally to avoid contamination. Deep joints should be filled in two or more runs, to prevent air entrapment.

• Once the sealant has been applied, a small timber spatula, soaked in soapy water, should be used to compact the sealant into the joints and to achieve a smooth polished finish. Any masking tape which has been applied should be removed before the sealant cures.

• Mixing and application equipment should be cleaned immediately.

How to apply: JOINT PREPARATION

1. The product may be used in sealant joints designed in accordance with SWR Institute's Sealants - The Professional's Guide. 2. In optimal conditions, the depth of the sealant should be ½ the width of the joint. The sealant joint depth (measured at the center) should always fall between the maximum depth of

12mm and the minimum depth of 6mm. Refer to Table 1. 3. In deep joints, the sealant depth must be controlled by closed cell backer rod or soft backer rod. Where the joint depth does not permit the use of backer rod, a bond breaker (polyethylene strip) must be used to prevent three-point bonding. 4. To maintain the recommended sealant depth, install backer rod by compressing and rolling it into the joint channel without stretching it


lengthwise. Closed cell backer rod should be about 3mm larger in diameter than the width of the joint to allow for compression. Soft backer rod should be approximately 25% larger in diameter than the joint width. The sealant does not adhere to it, and no separate bond breaker is required. Do not prime or puncture the backer rod. SURFACE PREPARATION

It is essential that joints be clean and dry. Joint surfaces must be structurally sound, fully cured, and free of all loose aggregate, paint, oil, grease, asphalt, wax, mastic compounds, waterproofing compounds, form-release materials, curing compounds or any other contaminants. NEW CONCRETE Remove all loose material from joints by wire brushing. Sandblast surfaces in contact with form-release agents. Fresh concrete must be fully cured. Laitance must be removed by abrading. OLD CONCRETE For previously sealed joints, remove all old material by mechanical means. If joint surfaces have absorbed oils, remove sufficient concrete to ensure a clean surface. PRIMING

1. Joint surfaces must be primed with MasterSeal P 101 before sealing. If the surfaces are other than masonry or concrete, test first to determine adhesion. Technical assistance is available from BASF. 2. Apply primer in a thin, uniform film. Avoid build-up of film. 3. Allow approximately 15–30 minutes drying time before applying sealant. (Primer should be tack free.) Sealant must be applied same day as primer. 4. To minimize contamination of adjacent surfaces, apply masking tape and remove before sealant has begun to thicken and set.

MIXING 1.MasterSeal SL 2 is a multi-component system with a configuration of Part A, Part B and sometimes a color pack. 2. Transfer entire contents of Part B to Part A container using a spatula or margin trowel. 3. Part B must be mixed thoroughly with Part A. Before adding pigment, scrape sides of container to ensure complete mixing of Parts A and B. With a slow-speed drill and a sealant mixing paddle, mix 4–6 minutes. Keep the paddle blade below the surface of the sealant to avoid whipping air into the sealant. 4. Transfer the entire contents of one MasterSeal 900 pigment can into the mixed Part A and B. Use a spatula or knife to remove all the pigment from the container. Continue mixing with a slow-speed drill and slotted paddle until color is uniform. During the process, scrape the sides and bottom of the mixing container several times to obtain a complete mix. 5. The pot life of mixed MasterSeal SL2 is influenced by temperature. See Table 2 for specific data. MasterSeal 905 accelerator may be added to adjust the initial cure rate. APPLICATION

1. All caulking and sealing should be performed when temperatures are above 40°F (4°C); any moisture or frost on surfaces will adversely affect adhesion. 2. Fill joints from the bottom; avoid bridging of the joint, which may form air voids. 3. For large joints, the self-leveling grade may be poured directly from the can. 4. For smaller joints and for all slope-grade applications, fill the joint by flowing the sealant from a bulk-loading gun. 5. Light tooling of the slope-grade sealant is recommended to smooth out ripples. On sloped surfaces, tool from the lowest point to the highest. Do not use soap or solvent. CURING

Cure time will vary with humidity and temperature. Initial cure is within 24 hours and complete cure takes approximately 7 days. Allow 14 day cure at 23°C prior to water immersion. Cure rates are dependent on temperature and humidity. Protect joint from dirt and traffic until cured. See Table 2 for use of MasterSeal 905 accelerator.


CLEAN UP

Immediately after use and before sealant has cured, clean equipment with MasterTop THN 2. Cured sealant may be removed by cutting with a sharp-edged tool. Remove thin films by abrading. STORAGE

Store in unopened containers in cool, clean, dry area out of direct sunlight. Elevated temperatures will shorten shelf life.

VOC CONTENT When mixed, product contains less than 64.4 g/L less water and exempt solvents. FOR BEST PERFORMANCE

Do not allow MasterSeal SL 2 sealants to come into contact with alcohol-based materials or solvents.

• Do not apply polyurethane sealants in the vicinity of uncured silicone sealants or uncured MasterSeal NP 150.

When MasterSeal SL 2 is to be used in areas subject to continuous water immersion, cure for 14 days at 70°F (23°C). Allow longer cure time at lower temperatures. Always use MasterSeal P 173.

Do not use in swimming pools, or other submerged conditions where the sealant will be exposed to strong oxidizers. Avoid submerged conditions where water temperatures will exceed 120˚ F (58°C).

For slopes up to 12% use MasterSeal SL 2 Slope Grade. For slopes over 12% use MasterSeal NP 2 sealant.

Backer rods, joint fillers or bond breakers must be tight to the sides of the joint to prevent loss of sealant through the bottom.

For joints subject to puncture by high heels or umbrella points, a stiffer or higher density backup material is required. Cork or rigid non-impregnated cane-fiber joint fillers are suitable.

Separate materials from the sealant by a non-adhering bond breaker (polyethylene tape).

Do not use other caulks or sand as a bottom bed in a joint.

Do not install when rain is expected before the sealant reaches initial cure (about 12 hours).

Units of MasterSeal SL 2 are premeasured; do not use partial units.

MasterSeal SL 2 may yellow in the presence of unvented artificial heat; this is a surface phenomenon that does not affect sealant performance.

Use only MasterSeal 900 color packs intended for use with MasterSeal SL 2.

APPLICATION TEMPERATURE:

The quality of the final coating is dependent on the substrate and the material temperatures, we recommend a substrate temperature of min. +12°C and max. +35°C. SURFACE PREPARATION AND PRIMING

The surface to be coated must be clean, dry free of laitance, oil, grease or any substance that may impair adhesion. The preferred methods of surface preparation are captive blasting, surface grinding or similar. Weak or damaged concrete must be removed, and replaced with a suitable repair compound from the MasterEmaco or MasterProtect range of products. Surface defects should be repaired using MasterTop 2200 or other suitable repair compounds from the MasterProtect or MasterEmaco range. PRIMING

Mix and apply MasterTop P 650 surface conditioner to the prepared dust free surface at approximately 0.15-0.30kg/m². Into the wet primer, scatter 0.6kg/m² MasterTop SR 3. MIXING AND APPLICATION

Mixing for MasterSeal M 866: Mix the A and B components of the MasterSeal M 866 together using a slow speed (400 rpm) drill with a spiral mixing head. Work the mixer round the mixing pail to ensure it scrapes the side and bottom of the pail. Pour mixed material into a clean pail and mix for a further 30 seconds. Pour the mixed material onto the floor and spread at the required coverage (minimum 0.5kg/m²) using pin screed or trowel. Into the wet MasterSeal M 866, broadcast aggregate MasterTop SR 3 to excess (from 1.0kg/m²). Allow to cure for 24 hours at 25°C. Remove excess aggregate by sweeping or vacuuming.
