All-in-One Membrane for Crack Isolation, Sound Reduction, Waterproofing and Vapor Management Mapesonic 2 is a patented, next-generation, flexible, 76-mil thin, lightweight, load-bearing, fabric-reinforced, “peel-and-stick” membrane for sound reduction, crack isolation, waterproofing and vapor management. Application of Mapesonic 2 can be immediately followed by installation of finished flooring. Mapesonic 2 reduces transmission of impact sound (such as footsteps and dropped objects) and airborne sound (such as voice and TV) through floors when installed under ceramic tile, stone, vinyl and wood floorings. It also helps to prevent existing or future in-plane floor cracks (with movement up to 3/8" or 10 mm wide) from transmitting through grout, ceramic tile and natural-stone assemblies.

• Patented design: Sound-reduction performance with less weight and thickness
• ASTM C627 Service Rating (Robinson): Extra Heavy
• Dual protection: Provides sound reduction and crack isolation
• Semi-rigid sheet: Easy to position on floor and cut to size
• Split-back release film: Installs faster than membranes with one-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, vinyl or wood immediately
• No odor: Great for confined spaces
• Contains post-industrial, recycled material
