Mapei Mapeguard UM is a thin, lightweight, and highly flexible premium flooring underlayment polypropylene membrane (floor mat), engineered for neutralizing tension, uncoupling membrane for tile, crack isolation, waterproofing characteristics, and vapor management solutions in ceramic tile and stone installations.
Designed for both commercial and residential flooring applications, this advanced underlayment solution provides enhanced durability and flexibility, effectively preventing tile cracking, delamination, and lateral stress from transferring to tile covering surfaces in bathrooms, kitchens, shower floors, steam rooms, laundry rooms, basements, living rooms, dining rooms, entryways, hallways, and other high-moisture areas. It is also ideal for commercial spaces such as hotels, restaurants, retail stores, office buildings, shopping malls, healthcare facilities, and industrial kitchens, providing long-lasting protection in high-traffic environments.
The tri-layered design of Mapeguard UM features a textured foil layer, backing fleece, and fiber reinforcement mesh, allowing it to absorb substrate movement and shear stress without transferring this force to the tile or stone flooring. This innovative premium infloor uncoupling layer compensates for differential movement in all directions, ensuring a strong and stable tile installation over plywood, OSB, wood, concrete, cement backer board, gypsum, and properly prepared tiled subfloors. The translucent structure allows for easy verification of adhesive thin-set mortar coverage, ensuring even bonding and a secure floor system.
Mapei uncoupling waterproofing and crack prevention membrane (underfloor mat) is ideal for use in your shower, bathroom tile, kitchen tile, hot tub surround and bathtub surround, laundry room, and living room floors.

Choosing The Right Thin-set Mortar for Mapeguard Membrane Installation:
For bonding Mapeguard UM to the substrate, Mapei recommends using polymer-modified mortars such as Ultraflex 1 and Ultraflex 2. These mortars provide excellent adhesion between the membrane and substrate, ensuring proper bonding.
When installing tile over the Mapeguard UM membrane, large-and-heavy-tile mortars are ideal. Products like Ultraflex LHT, Ultraflex LFT, Ultraflex LFT Rapid, and Ultraflex LHT SG are recommended. These mortars are specifically formulated to support the weight of large-format tiles and prevent sagging during installation.
A highly versatile, nonsag/nonslump, large-and-heavy-tile mortar suitable for tile and stone installations on floors, walls, and countertops. It offers excellent adhesion and can be used over uncoupling membranes.
A premium, extra smooth, large-and-heavy-tile mortar with polymer, ideal for installations on floors, walls, and countertops. It provides enhanced adhesion and flexibility.
A premium unmodified thin-set mortar specifically formulated for use with Schluter® membranes and boards. It is suitable for use with ceramic, porcelain, and stone tile, including large and heavy tile.
A premium, cement-based mortar designed for the installation of ceramic tile and stone over uncoupling membranes. It meets the requirements of ANSI A118.1 for non-modified thin-set mortars.
Ensure that the substrate is clean, dry, and free from contaminants that could affect adhesion. Proper surface preparation is essential for optimal performance.
