Mapei - Mapeguard UM Superior performance underlayment membrane for waterproofing and vapor pressure balancing 39" x 98' 4"

Mapeguard UM is a premium performance, lightweight waterproofing and vapor pressure balancing underlayment membrane that provides crack suppression and is suitable for use under ceramic tile and stone installations in residential and commercial applications. It is designed to perform on demanding substrates, such as young concrete and single-ply 19 mm (3/4") plywood subfloors with joists spaced up to 49 cm (19.2") on center. The unique technical three-layer design of Mapeguard UM absorbs lateral stresses from the substrate without transferring this force to the tile or stone, thus maintaining exceptional adhesion.

• Prevents the transfer of horizontal cracks in the plane up to 3 mm (1/8")
• FastTrack Ready MC – Approved for use on young (fresh) concrete and mortar screeds
• Saves time: place the membrane, then lay the tiles immediately
• Hollow technical design makes it easy to fill the surface in one go with a lower quantity of mortar
