View MAXKOSKO Tile Crack Prevention Underlayment Mat Uncoupling Protection Helps absorb stresses caused by substrate movement, reducing the risk of tile and grout cracks. Double-Fleece Bonding Nonwoven fleece layers provide strong mechanical bonding with thin-set mortar for secure tile installation. Waterproof Core The waterproof membrane layer helps protect moisture-sensitive substrates when properly installed and sealed. Vapor Management Integrated channels allow residual moisture vapor to escape and improve installation reliability. Load Distribution Mortar-filled cavities help distribute loads evenly and provide stable support beneath tile surfaces. High Tensile Strength Three-layer construction provides improved tear resistance and long-lasting durability. Important Before Ordering Before Installation Compatible Applications: Designed for ceramic, porcelain, and natural stone tile installations. Required Substrate: The substrate must be flat, stable, clean, and free from dust, grease, or loose materials. Waterproofing Requirements: For waterproof installations, seams, corners, and transitions must be properly sealed. Professional Installation: Always follow local building codes, tile manufacturer recommendations, and thin-set mortar instructions. Applications MAXKOSKO Uncoupling Membrane is suitable for tile projects requiring movement protection, waterproofing, and improved installation reliability. Residential bathroom, kitchen, and floor tile installations Commercial tile flooring applications Ceramic, porcelain, and natural stone tile systems Tile installations over concrete, plywood, OSB, and approved substrates Projects requiring additional crack prevention and moisture protection Specifications Product Type Double-Fleece Uncoupling Membrane Structure PP Nonwoven + PVC Core + PP Nonwoven Main Functions Uncoupling, Waterproofing, Vapor Management, Load Distribution Applications Ceramic Tile, Porcelain Tile, Natural Stone Tile Installations Installation Temperature 41°F to 95°F (5°C to 35°C) Compatible Substrates Plywood, OSB, Concrete, Gypsum Underlayment, Radiant Heated Floors Tensile Strength Up to 50.8 lbf/in (89 N/cm) Installation MAXKOSKO Uncoupling Membrane is installed between the substrate and tile covering using suitable thin-set mortar. Proper substrate preparation and installation procedures are essential for long-term performance. Step 1: Prepare the Substrate Clean and inspect the installation surface. The substrate should be flat, stable, and free of dust, grease, or loose materials. Step 2: Apply Thin-Set Mortar Spread suitable thin-set mortar evenly over the prepared substrate using an appropriate notched trowel. Step 3: Install the Membrane Place the membrane onto fresh mortar and press firmly to achieve full contact. Ensure proper alignment before tile installation. Step 4: Install Tile Apply thin-set mortar over the membrane and install ceramic, porcelain, or stone tiles according to tile manufacturer requirements. Installation Notes Reverse-Wound Design: The membrane can be unrolled directly onto the mortar bed without flipping or repositioning, helping improve installation efficiency. Movement Joints: Required movement joints should be maintained at edges, transitions, and large tiled areas according to industry practices. Installation Temperature: Recommended installation temperature range is 41°F to 95°F (5°C to 35°C). Professional Installation: Always follow local building codes, tile manufacturer recommendations, and thin-set mortar manufacturer instructions. Frequently Asked Questions What is an uncoupling membrane used for? An uncoupling membrane helps separate the tile layer from substrate movement. It reduces stress transfer between the substrate and tile covering, helping prevent tile and grout cracking. How is this different from the MAXKOSKO Crack Prevention Underlayment Mat? The Double-Fleece Uncoupling Membrane is an upgraded solution featuring a three-layer structure with fleece bonding layers on both sides. Compared with the standard crack prevention mat, it provides additional uncoupling protection, waterproofing support, vapor management, and load distribution performance. For basic crack prevention applications, you can also view our Tile Crack Prevention Underlayment Mat . Can this membrane be used for waterproof tile installations? Yes. The waterproof core helps provide moisture protection when seams, corners, and transitions are properly sealed according to installation requirements. What types of tiles can be installed over this membrane? It is designed for ceramic tile, porcelain tile, and natural stone tile installations when used with suitable thin-set mortar. Can this membrane be installed over plywood or concrete floors? Yes. It can be used over approved substrates including plywood, OSB, concrete, gypsum underlayment, and radiant heated floors when properly prepared. Does this membrane replace proper substrate preparation? No. The substrate must still be structurally sound, flat, and properly prepared before installation. The membrane helps manage movement but does not correct structural issues. Guides & Resources Need Help Choosing the Right Tile Protection Solution?
