ImperGuard is a high performance water repellent intended for the protection of porous walls and facades against humidity. It penetrates deep into the pores of materials to make them impermeable and thus limits the damaging effects of humidity: infiltration, acid rain, erosion, freeze/thaw cycle, formation of moss and lichen, appearance of efflorescence or saltpetre.

The product's water-repellent properties are acquired very quickly (from a few hours to 3 days). ImperGuard is a non-film-forming impregnation product, so the support remains permeable to air and water vapour. Completely colorless after application, it does not modify the appearance or the nature of the treated material. In addition, it is perfectly resistant to UV and does not yellow over time.
