SW-244 is a heavy duty, DOT grade, Type II siloxane, concrete surface treatment. It penetrates the surface and bonds chemically to the substrate, resulting in permanent attachment of the water repellent molecule. SW-244 is not a coating and as a result will not discolor or change the surface appearance in any way.
SW-244 can be used on most vertical or horizontal, exterior, above-grade surfaces. Coverage rates vary from 100-250 sq. ft. per gallon, depending on surface porosity and texture.
