ImperGuard® is a high performance water-repellent product for protecting porous walls, facades and roofs from humidity. ImperGuard® penetrates deeply into the pores of the material to make it impermeable and so prevent the harmful effects of humidity: infiltrations, acid rain, erosion, freeze/thaw cycle, moss and lichen growth, efflorescence, saltpetre, etc.
The chemical composition of the solution also enables it to perform as well as a solvent-phase product. The water-repellent properties of ImperGuard® are therefore developed very quickly (within a few hours to 3 days).
ImperGuard® also has an anti-dusting action and hardens the surface of materials.
ImperGuard® is a penetrating, non-film-forming product. The substrate remains permeable to air and water vapour. Completely colourless after application, it modifies neither the appearance nor the nature of the treated material. In addition, it is completely resistant to UV light and does not yellow with age.
