KEY EPOCON SL is a 90-125 mils thick self-leveling moisture vapor control system utilizing Key Epocoat technology, a unique water-based epoxy which allows the contractor to install polymer resin floor systems and other moisture sensitive floor coverings on new concrete (5 days old) or any concrete substrate emitting excessive moisture vapor without fear of moisture related blistering or delamination. Key Epocon SL is applied in a two coat application. Key Epocoat is the primer/basecoat used in the Key Epocon SL System. Key Epocon SL reduces the passage of water vapor and moisture through slabs on, above or below grade, thus eliminating delamination and blistering of adhesives, floor coverings, resin floor systems, epoxy terrazzo and coatings.

KEY EPOCON SL controls water vapor transmission levels for the installation of most floor covering systems, including VCT, sheet vinyl, carpets, wood, laminates, epoxy resin flooring and epoxy terrazzo.
