Protectosil® CHEM-TRETE® BSM 400
FOR BRICK, CONCRETE AND CONCRETE MASONRY BUILDINGS for unsurpassed performance
Protectosil® CHEM-TRETE® BSM 400 brings you the next generation in silane technology. Our chemists have developed a pure silane that yields a water repellent with the longest service life available, unsurpassed performance on brick masonry and the lowest possible levels of volatile organic compounds. Protectosil® CHEM-TRETE® BSM 400 can be applied in the most extreme temperature conditions without changing the surface appearance of the substrate.
By penetrating the surface and creating a chemical bond, Protectosil® CHEM-TRETE® BSM 400 permanently attaches to the substrate. It is ideal for use on exterior above-grade brick masonry, concrete and most natural stones. By reducing the amount of water entering the substrate, Protectosil® CHEM-TRETE® BSM 400 reduces the intrusion of water-borne contaminants such as acid rain, salt and dirt, and reduces the deteriorating effects of these contaminants, including spalling, scaling, efflorescence, leaching and staining.
