Concretal® W is a high-performance mineral sol silicate opaque finish specifically engineered for new and old concrete, where added protection against the weather, or a long-lasting color finish is required. Using only mineral and sol silicate binders, coupled with mineral pigments and fillers, Concretal W is absolutely lightfast and will not fade, no matter how harsh the environment. The finish is highly water repellent and resists wind-driven rain meeting the requirements of ASTM G 154.
