Mapeguard™ 2

Premium Crack-Isolation and Sound-Reduction Sheet Membrane


Mapeguard 2 is a next-generation, flexible thin, 40-mil lightweight, load-bearing, fabric-reinforced “peel-and-stick” crack-isolation membrane. After application, ceramic tile or stone can be installed immediately with any polymer-modified cement-based mortar (ANSI A118.4 or better) or epoxy mortar (ANSI A118.3). Glue-down wood flooring can also be installed with any MAPEI urethane adhesive.
Mapeguard 2 helps prevent existing or future in-plane floor cracks (with movement up to 3/8" [10 mm] wide) from transmitting through grout, ceramic tile or natural stone. It also reduces impact sound (footsteps, dropped objects, etc.) and airborne sound (voice, TV, etc.) transmission through floors when installed under ceramic tile, stone or wood floor coverings.
