ImperGuard SR (special roofing) is one of the best high performance waterrepellent sealers for protecting porous roofings from humidity.
ImperGuard SR penetrates deeply into the pores of the material to make it impermeable and so prevents 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 properties of water repellent sealer ImperGuard SR, are therefore developed very quickly (within a few hours to 3 days).
ImperGuard SR is a deep penetrating sealer and is a 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.
ImperGuard SR can be used outdoors on porous roofings in terracotta or cement. ImperGuard SR is used for new and renovated constructions.
