High-performance water repellent for the backs of porous stones.
ImperGuard® BC is a high-performance water-repellent that protects against damp on the underside of stones before they are laid.

ImperGuard® BC penetrates deeply into the pores of materials in order to make them impermeable and therefore limit absorption by the capillary action of the water in the mortar which causes visible stains after laying.

ImperGuard® BC is a non-film forming impregnation product, the material remains permeable to air and water vapour. Completely colourless after application, it does not change the appearance or the nature of the treated material.
