The product penetrates the surface and bonds chemically to the substrate, resulting in permanent attachment of the water repellent molecule. Protectosil® CHEM-TRETE® 40 D is not a coating and as a result will not change the surface appearance of the substrate. By reducing the amount of water that enters the substrate, Protectosil® CHEM-TRETE® 40 D reduces the intrusion of water-borne contaminants such as acid rain, dirt and pollutants. It also reduces the deteriorating effects of these contaminants, such as spalling, deicer scaling, efflorescence, subflorescence, leaching and staining.
