| Product Description: A penetrating, waterborne, vapor-permeable water repellent for use on concrete, brick, concrete masonry units and some natural stones. A ready-to-use, low-VOC, silane/siloxan emulsion. Reduces the ingress of water and waterborne contaminants into the substrate and thereby prevents premature deterioration. Penetrates the substrate and chemically bonds with silica to form a permanent attachment of water repellent is especially suited for applications where solvent-borne products are not acceptable, such as states that have VOC regulations for AIM coatings. Protectosil AQUA-TRETE EM is VOC compliant in all 50 states, including California’s SCAQMD. By reducing the ingress of water and waterborne contaminants into the substrate, Protecosil AQUA-TRETE EM reduces such problems as efflorescence, leaching, acid rain deterioration, scaling, dirt buildup, staining, corrosion of reinforcing steel and 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 to the masonry. Applications: Brick masonry, especially single with wall construction, can be treated to prevent moisture absorption. Concrete masonry units (medium-to normal-weight split-face, fluted or ground-faced blocks) can be protected from the ingress of wind-driven rain. From use on concrete to protect from the effect of water, deicing slats and other waterborne chemicals. Keeps the substrate clean by reducing the amount of dirt and other pollutants that may be absorbed. Other substrates that can be protected include stucco, sand-stone, terra-cotta, hand molded bricks and some natural stones. Advantages: Protecosil AQUA-TRETE EM is a silane/siloxane moisture in a proprietary emulsion system. Unlike some other silane or siloxane emulsion systems, Protecosil AQUA-TRETE EM is ready to use and is suitable for brick and concrete, without the need to blend oils, silicones, stearates or acrylates into the system. Protecosil AQUA-TRETE EM is designed to provide a high level of surface beading with penetration to protect against wind-driven rain. The active components are unique because they chemically bond to the silica in the substrate and set up a hydrophobic layer of protection. Because of this unique chemistry, Protecosil AQUA-TRETE EM has a long service life. By incorporating Protecosil AQUA-TRETE EM into your integrated design, you can earn vital Leadership Energy & Environmental Design (LEED) credits for both new and existing construction projects. The main benefits of the product are: - Non flammable
- High resistance to wind-driven rain
- Reduced efflorescence
- Breathable system
- Good penetration into substrate
- High resistance to alkali attack
- Keeps substrates cleaner
