Exposed decks are continually subjected to intense UV rays and harsh weather. The most challenging areas of MLCP, these decks need a durable, abrasion resistant, and anti-skid flooring, with additional features like crack-bridging ability and light stability. Dr. Cipy recommends a multipolymer system consisting of epoxy primer, crack-bridging PU membrane, silica broadcast, aromatic PU intermediate coat, and aliphatic PU topcoat.
