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. This product penetrates the surface to chemically bond to the substrate, resulting in a permanent attachment of the water repellent molecule. Protectosil® CHEM-TRETE® 40 VOC 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, Protectosil® CHEM-TRETE® 40 VOC reduces the intrusion of waterborne contaminants such as salt and dirt, and reduces the deteriorating effects of these contaminants, such as rebar corrosion, spalling, scaling, efflorescence, leaching and staining.
