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 to water and so prevent the harmful eﬀects of humidity: infiltration’s, 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. Water will bead off treated surfaces, but moisture in the substrate can still escape as 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.
