Key Components
Schluter-KERDI Waterproof Membrane
Ultra-thin polyethylene membrane with fleece webbingBonds directly to substrates using unmodified thin-set mortarCreates 100% waterproof barrierVapor-permeable to prevent moisture buildupSchluter-KERDI-DRAIN
Integrated drain assembly designed to work with KERDI membraneAvailable in various outlet configurationsIncludes hair strainer and odor trapCreates seamless waterproof connectionSchluter-KERDI-BOARD
Lightweight, waterproof construction panelReplaces traditional cement backer boardCan be cut with standard toolsProvides stable, flat surface for tile installationSchluter-KERDI-BAND
Waterproof strip for sealing joints and connectionsUsed at changes of plane (wall to floor, inside corners)Self-adhering for easy installationEnsures continuous waterproof barrierInstallation Process
Surface Preparation
Clean substrate: Remove all debris, oil, and loose materialCheck for level: Ensure surfaces are plumb and levelPrime if necessary: Some substrates require primer applicationInstall drainage slope: Create proper slope to drain (1/4" per foot minimum)KERDI Membrane Installation
Apply thin-set mortar: Use unmodified thin-set in smooth, even layerInstall membrane: Press KERDI into mortar using flat side of trowelRemove air bubbles: Ensure full contact with no voidsOverlap seams: Minimum 2" overlap at all seamsSeal penetrations: Use KERDI-SEAL or KERDI-BAND around fixturesDrain Installation
Position drain: Center drain in proper location with correct slopeCut membrane: Create opening slightly smaller than drain flangeApply sealant: Use KERDI-CAULK around drain connectionInstall drain assembly: Follow manufacturer's torque specificationsTest system: Flood test for 24 hours before proceedingFinal Steps
Install tile: Use appropriate thin-set mortar for tile typeGrout joints: Allow proper cure time before groutingApply sealers: Seal grout and any natural stone surfacesInstall fixtures: Complete plumbing and accessory installationBenefits of Schluter Systems
