Mapei Mapesonic-2 Peel and Stick Membrane is a next-generation, peel-and-stick membrane designed for sound reduction, crack isolation, waterproofing, and vapor management in flooring installations. At just 76 mil thick, this lightweight, load-bearing, fabric-reinforced membrane offers exceptional performance without adding bulk. Its patented design allows for quick installation—simply prime, peel, stick, and immediately install tile, vinyl, or wood flooring.
Mapei Mapesonic-2 Peel and Stick Membrane significantly reduces the transmission of impact sounds like footsteps and airborne sounds such as voices and TV through floors, making it ideal for multi-family or multi-story buildings. It also helps prevent existing or future in-plane cracks (up to 3/8" wide) from transferring through grout, ceramic tile, or natural stone assemblies. Certified for indoor air quality and made with recycled materials, Mapei Mapesonic-2 Peel and Stick Membrane is a sustainable solution for high-performance flooring systems.
