Protectosil® CHEM-TRETE® 40 VOC

Protectosil® CHEM-TRETE® 40 VOC is a clear, penetrating, breathable water repellent for use on exterior above-grade concrete, brick masonry, concrete masonry units and some natural stones. The product penetrates the surface and bonds chemically to the substrate, resulting in permanent attachment of the water repellent molecule. It is not a coating and as a result will not discolor or change the surface appearance in anyway.

By reducing the amount of water entering the substrate, Protectosil® CHEM-TRETE® 40 VOC decreases the intrusion of water-borne contaminants such as salt and dirt, and reduces the deteriorating effects of these contaminants, such as rebar corrosion, spalling, scaling, efflorescence, leaching and staining.
