ImperGuard SF (special facades) is one of the best high performance waterrepellent sealers for protecting porous walls and facades from humidity.
-
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 properties of water repellent sealer ImperGuard SF, are therefore developed very quickly (within a few hours to 3 days).
-
ImperGuard SF also has an anti-dusting action and hardens the surface of materials.
-
ImperGuard SF 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 SF can be used indoors and out on vertical surfaces. It is ideal for the water-repellent treatment of porous materials such as natural stone, concrete, rendering, brick... ImperGuard SF is used for new works or refurbishment.
