SW-244™ Siloxane

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.
