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.

• Dual protection: Provides crack isolation and sound reduction
• ASTM C627 service rating (Robinson): Rated “Extra Heavy”
• Lightweight: 35% lighter than previous generations of comparable membranes
• Semi-rigid sheet: Easy to position on floor and cut to size
• Split-back release film: Installs faster than membranes with 1-piece liners
• White surface: Easy to view under lower-light conditions
• Thin-film adhesive backing: Bonds to a variety of substrates
• Time-saving: Prime, peel, stick and then install tile or wood immediately
• Low-odor: Great for confined spaces
• Contains 5% post-consumer recycled material
