| Product Description: A clear, penetrating, breathable water repellent for use on concrete, brick, concrete masonry units and some natural stones. Prevents water and waterborne contaminats from entering the substrate and causing premature deteroration. Penetrates into the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. Protectosil CHEM-TRETE PB VOC is especially suited for making porous substrates such as split-face block water repellent. This water repellent effect stands up against wind-driven rain. By preventing water and waterborne contaminants from entering the substrate, Protectosil CHEM-TRETE PB VOC reduces problems such as efflorescence, leaching, acid rain deterioration, scaling, dirt buildup, staining, corrosion of reinforcing steel and mildew. Protectosil CHEM-TRETE PB VOC will not cause adverse surface appearance of the substrate. Treated surfaces are fully breathable because the natural moisture vapor transmission is not affected. This will eliminate problems caused by entrapped moisture, including blushing of the sealer and freeze-thaw damage to the masonry. Applications: Materials such as concrete masonry units (split-face, fluted or ground-faced blocks) can be protected from the ingress of wind-driven rain. Brick masonry, especially single with wall construction, can be treated to prevent moisture from entering and damaging interior walls. Provides resistance against water and waterborne contaminants to reduce staining. Other substrates that can be protected include sandstone, terra-cotta, hand-molded bricks and natural stones. Advantages: Protectosil CHEM-TRETE PB VOC is a proprietary mixture of alkyltrialkoxysilanes. The Protectosil CHEM-TRETE PB VOC is designed to provide a high level of surface beading with penetration, to protect against wind-driven rain. The silane components are unique because they chemically bond to the silica in the substrate and set up a hydrophobic layer of protection. Because of the silane’s unique chemistry, a long service life is possible. By incorporating Protectosil CHEM-TRETE PB VOC into your integrated design, you can earn vital Leadership and 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
- Reduced efflorescence
- Breathable system
- Deep penetration into substrate
- Long service life
- Substrates already treated with Protectosil CHEM-TRETE PB VOC can be painted over
- Keeps substrates cleaner
