RocCrete F20 is a liquid applied two component highly flexible acrylic modified cementitious coating system which requires only simple on-site mixing to provide an excellent adhesion, flexibility crack bridging ability and durability. Hard wearing, waterproof membrane for roof and foundation protection. In exposed areas It is highly recommended an over coat of Rocshield or RocShield HR
RocCrete F20 is a blend of specially selected cements, precisely graded silica, dolomite fillers and chemical admixtures with a liquid component of pure acrylic copolymer and wetting agents.
Thoroughly dampen down the concrete surface with clean water prior to application. Ideal conditions are saturated surface dry (SSD). Do not apply to dry concrete. Whilst damp, apply RocCrete C40 with a bristle brush or roller at the rate of 1.8 kg/m2. This is achievable in one coat on horizontal surfaces although two coats will ensure even coverage and remove pin holing. On vertical or overhead surfaces 2 or 3 coats may be required. Where more than 1 coat is required, the previous coat should be allowed to dry prior to subsequent applications.
