OVERVIEW

PROSOCO® SL40 Water Repellent chemically reacts with the substrate to produce a long-lasting water repellent effect. The product’s low viscosity and small molecular size allows maximum penetration into the concrete or masonry surfaces. Surfaces treated with SL40 maintain their natural appearance, vapor permeability, slip resistance and other surface characteristics.
