    ARDEX Liquid Backer Board - Self-Leveling Underlayment for Interior Wood and Concrete Subfloors

    ARDEX Liquid BackerBoard® Self-Leveling Underlayment for Interior Wood and Concrete Subfloors is a pourable blend of Portland cement and other hydraulic cements that replaces traditional backerboards for a faster, easier, seamless installation of tile and stone over wooden subfloors, concrete, terrazzo, ceramic tile and epoxy, eliminating the need to cut, fit, glue and fasten. ARDEX Liquid BackerBoard DOES NOT REQUIRE LATH MESH, even when used to smooth and level wood subfloors. Tile and stone can be installed in as little as 6 hours. ARDEX Liquid BackerBoard is also suitable for the installation of engineered wood plank and laminate floor coverings and for encapsulating in-floor electrical heating systems.
