Mapei Mapeguard UM Underlayment Membrane

Mapeguard UM is a premium-performance, lightweight, waterproofing and vaporpressure-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.

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.

Features & Benefits
  • Prevents transmission of in-plane substrate cracks up to 1/8" (3 mm)
  • 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 lbs. (11,3 kg) 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
  • Reduced “roll memory” and unique tri-layer construction keep membrane flat.
  • Lightweight for easy handling and fast installation Easy to cut with standard utility knife
  • Chalk and laser lines easily visible on surface
  • Mesh-fabric top layer makes it easy to fill cavities with mortar.

Where to Use
  • Residential (homes, apartments and condominiums) and commercial (office buildings, restaurants, galleries and malls) floors, both interior and exterior
  • Use for renovating older floors to address existing in-plane cracks in the subfloor.
  • Use to isolate stresses beneath the flooring associated with expansion and contraction of substrate materials.
  • Use to protect lateral stresses in industry-approved plywood or oriented strand board (OSB) floors from transferring to the finished tile floor.
  • Offers an installation solution when the construction timeline requires installing tile over green or young concrete slabs before the full 28-day cure

Suitable Substrates
  • Concrete
  • Cement mortar beds, self-leveling underlayment and leveling coats
  • Young concrete
  • Industry-approved exterior-grade plywood and APA Sturd-I-Floor, Exposure 1 OSB (interior, dry areas only)
  • Approved backer units – see manufacturer’s installation guidelines
  • Cement terrazzo (properly prepared interior only)
  • Existing ceramic tile or stone (properly prepared interior only)
  • Radiant-heat systems
  • Existing, properly prepared vinyl flooring – vinyl
  • composition tile (VCT), non-cushioned paper-backed/ felt-backed sheet vinyl, luxury vinyl tile/plank (LVT/LVP)
  • Epoxy terrazzo (with appropriate bond testing – interior only)
  • Gypsum underlayment or lightweight concrete*
* Follow gypsum or lightweight concrete manufacturer’s recommendation regarding priming and/or special surface preparation before installing underlayment membrane. Reference MAPEI’s Technical Bulletin #010313-TB, “GypsumBased Floors and Walls: Which MAPEI Products Can Be Applied?”
