OVERVIEW
SL40 <600 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 <600 maintain their natural appearance, vapor permeability, slip resistance and other surface characteristics.
