Use Selectseal-W highly durable, waterborne, low-VOC, one-compound, clear acrylic-polyurethane sealer on new or existing concrete or cementitious toppings to improve resistance to staining, abrasion, and the effects of UV radiation. Sealed surfaces vary in appearance from matte to semi-gloss, depending on substrate porosity and the number of coats applied. L.M. Scofield Co.
