Mapeguard™ 2 - Crack Isolation and Sound Ctrl Membrane

Mapeguard 2 is a next-generation, flexible, thin, 40-mil (1-mm) lightweight, load-bearing, fabric-reinforced “peel-and-stick” crack-isolation, waterproofing and vapor-control membrane. Mapeguard 2 helps to prevent existing or future in-plane floor cracks (with movement up to 3/8" [10 mm] wide) from transmitting through grout, ceramic tile and natural stone. It also reduces the transmission of impact sound (footsteps, dropped objects, etc.) and airborne sound (voice, TV, etc.) through floors when installed under ceramic tile, stone or wood floor coverings.

• ASTM C627 (Robinson): See the “Product Performance Properties” section below for Mapeguard 2.

• ASTM E492-04 (Impact Sound), E90-04 (Airborne Sound), E2179 (Impact Sound): See the “Product Performance Properties” section below for Mapeguard 2.

• ANSI A118.12 (Crack Isolation For Tile & Stone): See the “Product Performance Properties” section below for Mapeguard 2. Mapeguard 2 exceeds the high-performance standard for crack isolation.

• Exceeds ANSI A118.13 industry standards for bonded thin-set ceramic sound-reduction membranes

• ANSI A118.10 (specifications for load-bearing, bonded, waterproof membranes for thin-set ceramic tile and dimension stone installations): See the “Product Performance Properties” section below for Mapeguard 2 (when used with Mapetape ™ BB sealing tape).

• ASTM E96 (standard test method for water vapor transmission of materials): See the “Product Performance Properties” section below for Mapeguard 2 (when used with Mapetape BB sealing tape)
