Bostik Cementone Integral Waterproofing Liquid 5 Litre

Bostik Integral Waterproofer is a liquid additive that provides long-term water protection to mortar, non-structural concrete and rendering. It is an alkaline soap of mixed fatty acids, which reacts chemically with cement to form hydrophobic salts, which reduce water penetration.
Bostik Integral Waterproofer helps reduce efflorescence and lime bloom by restricting moisture movement and helps reduce crazing in rich mixtures by controlling the rate of evaporation.
It waterproofs and plasticises mortar for external or basement renderings, pointing and in swimming pools, sewers and tank linings as part of the overall waterproofing system specification. It will not corrode reinforcing metalwork, but is not suitable for use in structural concrete.
