Features & Benefits

• High build application
• Can be applied directly to mild steel and concrete
• Smooth, glossy, easy to clean surface
• Corrosion, chemical and abrasion resistant
• Can be applied to damp surfaces
• Waterproof
• Ground gas and water vapour barrier
• BS 6920:2014 Effect on Water Quality
• Water Regulations Advisory Scheme Approved
• Compliant with the permeability requirements of BS 8485: 2015 Table 7 (Unjointed)

Uses

• Suitable for application to below ground retaining wall and foundation structures - including construction joints to maintain waterproofing and ground gas protection continuity - as part of a waterproofing and ground gas protection solution, conforming to BS8102:2009 and BS8485:2015
• Enables continuity of waterproofing and ground gas protection to be achieved in locations where the use of sheet membrane products is not feasible
• Compatible for use with the Proofex range of sheet membranes
• As a protective coating, suitable for lining and waterproofing potable water retaining structures and surfaces subject to contact with foodstuffs
• Corrosion, chemical and abrasion resistant and suitable for application to basements, tunnels, tanks, silos, reservoirs, water treatment works, breweries, dairies and meat and food processing plants
• Cured film is non toxic and meets the requirements of BS 6920

Application Notes

• It is recommended that mechanical mixing be employed, using a Fosroc Sealant Mixing Paddle on a heavy duty, slow speed electric drill
• The thoroughly mixed material should be applied with a suitably stiff brush or squeegee working the coating well into the surface particularly where uneven / textured substrates are present
• When touch dry carefully inspect the coated surface for pinholes and voids and fill in where required to ensure a completely unbroken coating is achieved
• For ease of overcoating, it is recommended that the first coat be white and the second coat blue, or vice-versa
• For cold weather working, it is recommended that the product be stored in a heated building and removed immediately before use, as workability deteriorates and curing times increase at lower temperature
• Where there is a requirement for a non-slip finish or additional shear resistance within a concrete construction joint an appropriate grade of aggregate should be broadcast into the finish coat as soon as applied. The use of Nitoflor Anti-Slip Grains (2-3mm) is recommended for construction joints

Limitations

• Should not be applied over existing coatings
• Application should not be undertaken if the temperature is below 5°C, or is 5°C and falling, nor when the prevailing relative humidity exceeds 90%
• Although the product may be applied to damp concrete, there must be no standing or running water
• Not colour stable when exposed to direct sunlight nor when in contact with some chemicals. On curing, the final colour can vary with curing conditions, and in adverse conditions such as low temperature and/or high humidity, a white bloom may appear on the surface. However, this does not affect the performance of the coating
• Before commencing application it is important to ensure that the product meets all current compliance requirements. The product meets the requirements of BS 6920 the United Kingdom Water Regulations Advisory Scheme but not Regulation 31 of the Water Supply (Water Quality) Regulations 2000
• In accordance with WRAS listing, when the product is used in contact with potable water, curing conditions are 21 days at 7°C
