- Long-lasting protection of concrete and masonry against the damaging effects of water and deicing salts
- Does not form a surface film or gloss
- Treated surfaces “breathe” – does not trap moisture
- Reduces efflorescence, mildew and atmospheric staining
- Forms an effective chloride screen that reduces corrosion of rebar in reinforced concrete caused by water and water-carried salts
- Safe for use on surfaces subjected to vehicle traffic
- Leaves little or no residue on clean window glass. Always test
- Safe for use on surfaces subjected to vehicle traffic
- Resists water penetration when applied over existing shrinkage cracks of 0.02 inches or less

SL40 Water Repellent
40% silane water repellent
Description
PROSOCO SL40 Water Repellent is a clear, penetrating silane water repellent containing a solution of silane reduced in solvents. SL40 protects horizontal and vertical concrete and masonry surfaces against water and waterborne contaminants. The product’s low viscosity and small molecular size allows maximum penetration into the concrete or masonry surfaces.
PROSOCO SL40 Water Repellent chemically reacts with the substrate to produce a long-lasting water repellent effect. Surfaces treated with SL40 maintain their natural appearance, vapor permeability, slip resistance and other surface characteristics. Depth of penetration is controlled by the application rate (loading rate).
