Mapei - Mapeguard 2 - Crack Isolation, Waterproofing and Sound Reduction Membrane - 39-3/8" x 68-5/8' - 1 mm (225 sqft)

Mapeguard 2 is a self-adhesive, fabric-reinforced, load-bearing, flexible, thin, lightweight, 1 mm (40 mil) thick, technologically advanced crack-isolation, waterproofing, and vapor control membrane. Mapeguard 2 also helps prevent the transfer of existing or potential in-plane cracks (with movement up to 10 mm [3/8"] wide) through grout, ceramic tile, and natural stone. It also reduces the transmission of impact sound (footsteps, falling objects, etc.) and airborne sound (voices, TV, etc.) through the floor when installed under ceramic tile, stone, and wood flooring.

• Dual Protection: Provides crack bridging and sound attenuation
• ASTM C627 (Robinson) Service Requirements: Rated "Very Severe"
• Lightweight: 35% lighter than similar membranes of previous generations
• Semi-rigid sheet membrane: Easy to cut and position on the floor ground
