Waterproof Membrane for Showers, 3.3 Ft X 98.5 Ft (323 Sq Ft), Schluter Membrane Roll Suitable for Shower Waterproofing, Tile Underlayment, and Waterproofing of Roof Tiles

1. Dimensions & Convenience Roll Size: 3.3 ft (1 m) wide x 98.5 ft (30 m) long. Total Coverage: 323 square feet (30 square meters) per roll. Key Advantage: The generous width minimizes seams in standard-sized rooms, streamlining installation and enhancing overall water containment reliability. The roll is engineered for easy handling and lies flat during application. 2. Advanced Material & Build Quality Composite Structure: Manufactured using a continuous lamination process that fuses a flexible, waterproof core with double-sided non-woven reinforcement. This creates a dimensionally stable sheet resistant to stretching and tearing. Installation-Ready Surface: The textured finish on both sides is optimized for mortar adhesion and is treated to resist static dust pickup during installation, keeping the work area cleaner. 3. Primary Performance Benefits Reliable Water Barrier: Creates an impermeable layer that protects floor and wall assemblies from water intrusion, helping to prevent structural damage. Crack Isolation: Helps to dissipate stress from minor substrate movement, reducing the risk of cracks being transmitted through to the finished tile surface. Surface Preparation: Bridges minor imperfections in the subfloor to create a uniform, solid surface ideal for tile installation. 4. Recommended Applications Residential: Full bathroom waterproofing (shower floors/walls, tub surrounds), kitchen backsplashes, laundry rooms, balcony decks, and basement moisture protection. Commercial: Waterproofing for hotel bathrooms, gym locker rooms, restaurant prep areas, and spa facilities. Specialized Uses: As an underlayment over radiant heated floors, a crack isolation membrane in remodeling projects, or a temporary protective cover for floors during construction

• 【Large Coverage for Seamless Installation】 Each roll measures 3.3 ft x 98.5 ft (323 sq ft), designed to cover large areas like bathrooms or kitchens with minimal seams. This reduces installation time, material waste, and potential weak points for water management.
• 【Tear-Resistant Triple-Layer Armor Construction】 Features a reinforced composite core laminated between two non-woven fabric layers. This “sandwich” structure provides exceptional puncture and tear resistance, preventing wrinkles and delamination for a stable, long-lasting underlayment.
• 【Textured Surface for Superior Tile Bonding】 Both sides feature a specially designed velvety texture that creates a strong mechanical bond with standard thin-set mortar. This significantly enhances tile adhesion, prevents slippage, and ensures a perfectly flat, durable tiling surface
• 【Versatile Waterproofing for High-Moisture Areas】 Ideal as a waterproof barrier in showers, bathrooms, saunas, kitchens, balconies, and basements. Compatible with various substrates including concrete, cement board, plywood, and existing tile, effectively protecting structural surfaces from water exposure
• 【Flexible & User-Friendly for DIY or Pro】 The material is highly flexible and easy to cut. It conforms easily to corners, curves, and complex shapes. Simple to install without special tools, saving on labor costs for both DIY enthusiasts and professional contractors.
