WATER REPELLENTS: SW-244-20 C Penetrating Silane Water Repellent

Product Data Sheet    Material Safety Data Sheet    Architectural Specification

PRODUCT DESCRIPTION

SW-244-20 C is a clear penetrating, breathable silane water repellent designed for the protection of exterior above-grade concrete, brick masonry, and some natural stones from the damage caused by water intrusion.  It penetrates the surface and bonds chemically to the substrate, resulting in permanent attachment of the water repellent molecule. SW-244-20 C is not a coating and as a result will not discolor or change the surface appearance in any way.

USAGE

For use on concrete to protect reinforcing steel from corrosion due to the effects of water, deicing salts and other water borne chemicals.

For use on brick masonry to protect against the entrance of wind-driven rain.

For use on concrete pavement on highways, and airport runways to reduce scaling due to deicer chemicals.

To reduce the effects of mildew, efflorescence, and stains on vertical concrete and masonry buildings.
