SilaneSeal 40

Water Repellent & Penetrating Sealer

SilaneSeal 40 is a clear, penetrating, breathable water repellent for use on exterior above-grade concrete, brick masonry, concrete masonry units and some natural stones. SilaneSeal 40 will penetrate into the surface and will bond chemically to the substrate, resulting in permanent attachment of the water repellent molecule. SilaneSeal 40 is not a coating and as a result will not discolor or change the surface appearance in any way. By reducing the amount of water entering the substrate, SilaneSeal 40 will reduce the intrusion of waterborne contaminants such as deicing chemicals, salt, and dirt and will reduce the deteriorating effects of these contaminants, such as rebar corrosion, spalling, scaling, efflorescence, leaching and staining.
