Description
Underlayment Membrane for Ceramic Tile and StoneMapeguard 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.
Specifications
- Prevents transmission of in-plane substrate cracks up to 1/8" and FastTrack Ready approved for use over young green concrete and mortar beds for faster project timelines
- Unique engineered tri-layered design absorbs lateral stress from substrate without transferring force to tile or stone, maintaining exceptional bonds with time-saving embed-then-tile installation
- Waterproofing and vapor-pressure-equalizing membrane with engineered cavity design allowing easy single-pass filling with less mortar for efficient installation on challenging substrates
