Protectosil® CHEM TRETE 40 D

Protectosil® CHEM-TRETE® 40 D is a clear, penetrating, breathable water repellent and consolidant for use on exterior above-grade calcareous stone such as limestone and marble, brick masonry and natural stone. This product penetrates the surface to chemically body to the substrate, resulting in a 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 waterborne contaminants such as acid rain, dirt and pollutants. This decreases the deteriorating effects of these contaminants, such as spalling, deicer scaling, efflorescence, subflorescence, leaching and staining.

Typical Applications

Makes limestone and marble water repellent, and acts as a surface consolidant. For use on brick masonry, to protect against the ingress of wind-driven rain and to harden soft bricks. For use on concrete that has a high percentage of limestone or coral aggregate, to consolidate and make water repellent. Reduces the damage that salt burst has on natural stone, and the effects of mildew, efflorescence and stains on vertical concrete and masonry buildings.

Benefits at a glance

Protectosil® CHEM-TRETE® 40 D is a mixture of isobutyltrialkoxysilane and ethyl silicate in an alcohol carrier. The silane/silicate mixture is designed to penetrate deep into the substrate and impart a high degree of water repellency. The silicate allows the silane to chemically bond to substrates that have little or no natural silica. This provides the substrate with long-lasting water repellent protection. Protectosil® CHEM-TRETE® 40 D also acts as a surface consolidant for binding loose or powdery surfaces. The ethyl silicate encapsulates the calcium carbonate in limestone and marble to form a denser material. Sandstone also is hardened when the silicate bonds with the quartz grains. By incorporating Protectosil® CHEM-TRETE® 40 D into your integrated design, you can earn vital Leadership in Energy & Environmental Design (LEED) credits for both new and existing construction projects.
The main benefits of the product are:
• High resistance to wind-driven rain
• Excellent resistance to chloride ion ingress
• Excellent resistance to acid rain
• Consolidates
• Reduced efflorescence
• Breathable system
• Deep penetration into substrate
• High resistance to alkali attack
• Keeps substrates cleaner
