MAPEI Mapeguard UM 35 Underlayment Membrane for Ceramic Tile and Stone 30 sqm- 323 sqft Blue rolls (Volume pricing available)

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.
