210™ is a premium, calcium aluminate-based, interior, self- leveling underlayment that can be used to create a smooth, flat or level surface prior to the installation of floor coverings. Its long working time, low shrinkage and superior leveling properties make it the ideal product for demanding applications on, above, or below grade. Sealed with a suitable coating, 210 is also the perfect decorative topping when a natural concrete look is desired. Topical stains, dyes and surface treatments further expand the decorative possibilities.
