Application

▪ Residential (homes, apartments and condominiums) and commercial (office buildings, restaurants, galleries and malls) floors, both interior and exterior

▪ Use as a replacement for cement backer board on plywood or oriented strand board (OSB) floors.

▪ Use for renovating older floors to address existing in-plane cracks in the subfloor.

▪ Use to isolate stresses beneath the flooring associated with expansion and contraction of substrate materials.

▪ Use to protect lateral stresses in industry-approved plywood or OSB floors from transferring to the finished tile floor.

▪ Offers an installation solution when the construction timeline requires installing tile over green or young concrete slabs before the full 28-day cure

Description

Mapeguard UM is a premium-performance, lightweight, waterproofing and vapor-pressure-equalizing underlayment membrane that provides crack suppression for use under ceramic tile and stone installations, for both residential and commercial applications. It is designed to perform over challenging substrates, such as young concrete and single-layer 3/4" (19 mm) plywood subfloors with joist spacing of up to 19.2" (49 cm) on center or up to 24" (61 cm) on center with double-layer plywood subfloors. The unique engineered tri-layered design of Mapeguard UM absorbs lateral stress from the substrate without transferring this force to the tile or stone, which maintains exceptional bonds.
