Bridge Deck Membrane Top Coat is a slow setting, 100% solids, two-component polymer product. Bridge Deck Membrane Top Coat is used as a waterproof membrane for protection against typical corrosion conditions that exist on many rail and DOT structures. Bridge Deck Membrane Top Coat is also used on applications requiring an aggregated topcoat. The slower setting membrane allows aggregate to be broadcast into the membrane before initial set. Bridge Deck Membrane Top Coat can be applied in temperatures down to -20˚F without effect on setup time or curing, and can be applied at specified thickness in one continuous application.
