EAMIGARD SNW is water-thinnable emulsion of an alkyltrialkoxy sealer for use as water repellent for concentrate, masonry, stone, and clay tile and brick surface. When applied to clean, prepared surfaces, the sealer penetrates below the surfaces where it reacts and forms a solid tack-free drying polysiloxane which acts as a highly water repellent surface and provides protection against water penetration, chlorides and air born pollutants. It exhibits excellent resistance to alkalis, carbonation and acid rain.
