SW-244-40 VOC™ Silane

SW-244-40 VOC is a DOT grade (Type I), 40% alkylalkoxysilane water repellent treatment designed for the protection of exterior above-grade concrete, brick masonry.  It penetrates the surface and bonds chemically to the substrate, resulting in permanent attachment of the water repellent molecule.
