Description
xUnderlayment membrane for ceramic tile and stone. 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 in plywood subfloors with joist spacing of up to 19.2 in on center. 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.
Prevents transmission of in-plane substrate cracks up to 1/8 in
Recommended for use with polymer-modified mortars
Fast Track Ready™ approved for use over young (green) concrete and mortar beds
Time-saving: embed membrane then install tile immediately
Engineered cavity design allows easy single-pass filling of surface core with less mortar
Uncoupling, waterproofing and water vapor membrane up to 25 lb MVER and 100% relative humidity
Compression resistance to support rolling loads
Approved for radiant-heating applications
Light green, translucent color shows mortar coverage under membrane
