| Product Description: A clear, penetrating, waterborne, breathable water repellent for use on concrete and masonry. Ready-to-use, low-VOC, silane emulsion. Reduces the ingress of water an waterborne contaminates that cause premature deterioration of the substrate. Penetrates the substrate and chemically bonds with silica to form a permanent attachment of the water repellent molecule. Protectosil AQUA-TRETE 20 water repellent is especially suited for application when solvent-borne products are not acceptable, as in states that have VOC regulations for AIM coatings. Protectosil AQUA-TRETE 20 meets all national and state VOC regulations. By preventing water and waterborne contaminates from entering the substrate, Protectosil AQUA-TRETE 20 reduces such problems are efflorescence, leaching, acid rain deterioration, scaling, dirt buildup, staining, corrosion of reinforcing steel mildew. Treated surfaces are fully breathable because their natural moisture vapor transmission is not affected. This will reduce problems that entrapped moisture can cause, including blushing of the sealer and freeze-thaw damage. Applications: For use on concrete to protect the reinforcing steel from corrosion due to the effects of water, deicing salts and other waterborne chemicals. Protects precast concrete (including GFRC) from the damaging effects of acid rain and freeze-thaw cycles. Keeps concrete clean by reducing the amount of dirt and other pollutants that it may absorb. Some denser concrete masonry units (split-face, fluted or ground-face blocks) and pavers can also be protected from water absorption. Other suitable substrates include brick masonry, sandstone, terra-cotta, hand molded bricks and some natural stones. Advantages: Protectosil AQUA-TRETE 20 is a silane/siloxane blend in a proprietary emulsion system. Unlike other silane or siloxane emulsion systems. Protectosil AQUA-TRETE 20 is ready to use and is suitable for concrete and brick masonry, without the need to blend oils, silicones, sterates or acrylates into the system. Protectosil AQUA-TRETE 20 is designed to provide a high level of repellency with penetration. The active components are unique because they chemically bond to the silica in the substrate and set up a hydrophobic layer of protection. By incorporating Protectosil AQUA-TRETE 20 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: - Non flammable
- Excellent resistance to chloride ion ingress
- Reduced efflorescence
- Breathable system
- Good penetration into substrate
- No change in surface appearance
- High resistance to alkali attack
- Long service life
- Substrates already treated with Protectosil AQUA-TRETE 20 can be painted over
- Keeps substrates cleaner
