Bostik Integral Waterproofer | 5 Litre

Bostik Integral Waterproofer 5 Litre (formerly Cementone Integral Waterproofer) is an alkaline soap of mixed fatty acids which react chemically with cement to form hydrophobic salts that reduce water penetration. Helping to reduce efflorescence and lime bloom by restricting moisture movement. It aids the reduction of crazing in rich mixtures by controlling the rate of evaporation.
