Mapeguard 2 is a high-quality, fabric-reinforced, flexible, thin, lightweight, 1mm (40mil) thick, high-tech crack-bridging and sound attenuation membrane. It allows the for immediate installation of tiles using a polymer-modified mortar. Wood glue coatings can also be used with Mapei urethane adhesive. Mapeguard 2 also helps prevent the transfer of existing or potential cracks (with a movement up to 10mm wide). It reduces the transmission of impact noises and airborne sounds through the ground when installed under tile or wood cladding.
