Imperguard SR Oil Water Repellent

One of the finest high performance water resistant sealers for porous roofing is Imperguard SR (special roofing). This sealer deeply penetrates the pores of the surface to render them impenetrable, preventing the negative effects of humidity such as infiltrations, acid rain, erosion, freeze/thaw cycles, the growth of moss and lichen, efflorescence, saltpetre, etc. Deep penetrating sealer Imperguard SR is a non-film-forming product. The substrate continues to be air and water vapour impenetrable. Buildings that are both new and renovated can use it on their roofs.
