SW-244-20 C is a spec grade clear, penetrating 20% alkylalkoxysilane water repellent 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.
SW-244-20 C can be used on most exterior horizontal and vertical above-grade surfaces. Coverage rates vary from 150-250 sq. ft. per gallon, depending on surface porosity and texture.
Does not leave residue on non-porous surfaces e.g. glass or windows
