Covering 323 sq ft per roll, it enables immediate tile installation, making it ideal for residential and commercial wet areas like bathrooms and steam rooms. Lightweight and easy to handle, it ensures durable, professional-grade protection for ceramic and stone tile floors with a 10-year warranty. ## Description Mapeguard WP 200 is a thin, flexible polyethylene sheet premium underlayment membrane with a nonwoven polypropylene fabric on both sides. It provides superior flooring protection, crack isolation and waterproofing for ceramic tile and stone installations. Mapei Mapeguard WP provides an effective waterproofing solution for modern bathrooms, residential living areas and commercial spaces such as restaurants, galleries and malls (food courts, lobbies, foyers). The Mapeguard WP's laminated fabric webbing binds the membrane to the substrate and the upper layer (bathroom tiles). It is installed using the uncoupling membrane mortar (thin-set mortar adhesive). Mapeguard membrane has a low permeability rating for vapor protection in showers and steam rooms to make your underlayment for tile waterproof. Mapeguard tile membrane underlayment can also be used when renovating older floors, including DIY projects. It addresses the existing in-plane cracks in the bathroom tile subfloor and prevents lateral stresses in plywood floors from being transferred to the finished tile floor or stone tiles. Moreover, it allows for immediate tiling after installation, making it perfect for time-sensitive bathroom floor tile construction. A modern residential house often has a combination of water sources such as bathtubs, showers, hot tubs and steam rooms. Mapei Mapeguard WP waterproofing membrane is uniquely engineered to deliver waterproofing, crack-isolation and vapor-control home solutions. With its low perm rating, the WP 200 system is approved for residential and commercial use, with critical demand for vapor and water protection. Please be advised that ceramic, porcelain, travertine, limestone, marble, agglomerates, glass tile, or stone set over Mapeguard WP 200 may require the use of a self-leveling underlayment or a cured mud-bed application. Careful handling and correct installation help maximize its performance and service life. ## Features - Waterproof crack isolation: Mapeguard WP 200 is a waterproofing and vapor control flooring underlayment with high-performance crack isolation up to 1/8 Inch (3 mm). - It has a uniform thickness with a thin profile.
