Selectseal W sealer is a water-based acrylic-modified polyurethane. Unlike many sealers, the one-component system provides UV protection to surface finishes such as dyes or other color applications that may be UV sensitive. Selectseal W also has good abrasive-resistant characteristics, and good stain and acid resistance. Selectseal W can be placed inside or outside and is moisture tolerant. L M Scofield Co. 800-800-9900.
