Bostik Integral Waterproofer reacts chemically with cement to form hydrophobic salts that reduces water penetration. It reduces efflorescence and lime bloom by restricting moisture movement whilst aiding the reduction of crazing in rich mixtures by controlling the rate of evaporation. It waterproofs and plasticises mortar for external or basement renderings and in swimming pools, sewers and tank linings as part of the overall waterproofing system specification.
