WATERpROOFING MEMBRANE - Centura

WATERPROOFING MEMBRANEINNOVATIVE SOLUTIONS FOR CERAMIC AND STONE TILEBonded Waterproof Membrane and Vapor RetarderCeramic and stone tiles are durable, easyto maintain, and hygienic, representingideal surface coverings in wet areas.However, since tiles and grout are notinherently waterproof, it is essential toprotect the substrate from moisturepenetration.Application and Function8.1 Schluter ® -KERDI is a pliable, sheetapplied,bonded waterproof membrane andvapor retarder with limited crack-bridgingcapabilities. It is made of soft polyethylene,which is covered on both sides with a specialfleece webbing to anchor the membrane inthe thin-set mortar.Schluter ® -KERDI was developed as awaterproofing membrane to be used inconjunction with ceramic and stone tilecoverings. Tiles can be installed directlyon Schluter ® -KERDI using the thin-bedmethod. Other trowel-applied coveringmaterials, such as plaster, can also beused.Pre-formed sections of Schluter ® -KERDIare available for inside and outside corners,pipe protrusions and mixing valve openings.Use Schluter ® -KERDI-BAND, in widths of 5"(12.5 cm), 7-1/4" (18.5 cm), or 10" (25 cm)to seal butt joints or corner joints. Schluter ® -KERDI-FLEX, in 5" (12.5 cm) or 10" (25 cm)widths, is used to seal expansion joints orflexible edge joints.Material Properties andAreas of ApplicationSchluter ® -KERDI is a polyethylene waterproofingmembrane with a very lowvapor permeance of 0.75 perms. Thematerial is physiologically safe. Schluter ® -8.1 Schluter ® -KERDIKERDI has been independently tested andfound to emit zero VOCs per CaliforniaSpecification 01350: “Standard Practice forthe Testing of Volatile Organic Emissionsfrom Various Sources Using Small-ScaleEnvironmental Chambers”. Thus, Schluter ® -KERDI can contribute towards achievingthe following green building credits:• LEED, IEQ Credit 4.3: Low-EmittingMaterials - Flooring Systems• ICC 700-2008, 901.6: Pollutant SourceControl - Hard-Surface Flooring• CHPS, EQ2.2: Low-Emitting MaterialsSchluter ® -KERDI requires no specialdisposal.Schluter ® -KERDI is waterproof and resistantto most chemicals commonly encounteredin tiled environments. It is resistant toaging and will not rot. Schluter ® -KERDI isH = 8 milhighly resistant to saline solutions, acid andalkaline solutions, many organic solvents,alcohols, and oils. Information regardingits resistance to specific substances can beprovided if concentration, temperature, andduration of exposure are known. For acidresistantcoverings, use an epoxy adhesiveto set and grout the tile.Schluter ® -KERDI is suitable for wall andfloor surfaces where protection against thepenetration of moisture or other harmfulsubstances is necessary. Applicationsinclude showers, steam showers, tubsurrounds, and areas surroundingswimming pools. Industrial applications

WATERPROOFING MEMBRANESchluter ® -KERDI-DRAIN assembly withSchluter ® -KERDI waterproofing membrane.include the food industry, breweries, anddairies. Before placing the Schluter ®-KERDI, verify that the substrate is clean,even, load bearing, and free from moisture.Surfaces that inhibit proper adhesion mustbe removed or appropriately treated.Schluter ® -KERDI meets the AmericanNational Standard for Load Bearing,Bonded, Waterproof Membranes forThin-Set Ceramic Tile and Dimension StoneInstallations (ANSI A118.10). The membraneis listed by cUPC® and evaluatedby ICC-ES (Report No. ESR-2467). Forcopies of these documents, please contactSchluter ® -Systems at (800) 472-4588 (USA)or (800) 667-8746 (CAN) or by e-mail atinfo@schluter.com. Links to the documentscan also be accessed at www.schluter.com.Installation1. The substrate must be clean, even, andload bearing. The thin-set mortar usedfor bonding Schluter ® -KERDI must beappropriate for the substrate, and itmust penetrate and engage the KERDIfleece. Generally, an unmodified thinsetmortar is used. Cut Schluter ®-KERDI to size prior to application.2. Apply thin-set mortar to the substrateusing a 1/4" x 3/16" (6 mm x 4 mm)V-notched trowel or the Schluter ® -KERDI2trowel, which features a 1/8" x 1/8"(3 mm x 3 mm) square-notched design(Note the open time of the mortar). PressSchluter ® -KERDI fully into the bond coat.Work the KERDI into the mortar byapplying pressure to the membrane withthe flat side of the trowel (held at anangle) in smooth, diagonal sweeps. Airbubbles must be avoided.3. Seams can be constructed byoverlapping the edges of the KERDI2" (5 cm) using unmodified thin-setmortar, or by abutting the edgesand covering the joint with Schluter ®-KERDI-BAND using an unmodifiedthin-set mortar.4. For inside and outside corners,adhere pre-formed Schluter ® -KERDI-KERECK-F corners. For floor/wallconnections, use the Schluter ® -KERDI-BAND. Install KERDI-SEAL-PS pipeseals at showerhead, body sprays,etc. and KERDI-SEAL-MV at themixing valve. As an alternative toKERDI-SEAL-PS/-MV, KERDI-FIX orequivalent sealant can be used to sealpipe protrusions and protect moisturesensitivesolid backing panels at themixing valve.5. Connections to fixed building elementscan be achieved by using Schluter ®-KERDI, KERDI-BAND, or KERDI-FLEXin conjunction with: Schluter ® -KERDI-FIX; suitable trowel-applied waterproofingmaterials (such as urethaneor similar), which require atmosphericmoisture to cure; or other suitablesealing compounds.6. Schluter ® -KERDI shall be separatedat existing expansion, structural, andflexible edge joints. Cover the jointswith Schluter ® -KERDI-FLEX. To allowfor greater movement, the centersection of the Schluter ® -KERDI-FLEXcan be tucked into the cavity of theexpansion joint prior to bonding.7. Once the entire membrane—withseams, corners, and connections—has been completely bonded, andtherefore waterproofed, the coveringmay be applied.Note: Water testing of the assemblyPrior to setting tile, wait 24 hoursto allow for final set of the mortarbefore testing to ensure waterproofperformance of the assembly at seamsand connections.8. For tile installations using the thinbedmethod, apply unmodified thinsetmortar directly to the exposedSchluter ® -KERDI surface and installthe tiles, ensuring full coverage. Foracid-resistant coverings, use an epoxyadhesive to set and grout the tile.Connection to Schluter ® -KERDI-DRAINSchluter ® -KERDI-DRAIN is a floor drainspecifically designed to allow connectionsto Schluter ® -KERDI or other bondedwaterproof membranes, typically in showerapplications. When adhering Schluter ®-KERDI to Schluter ® -KERDI-DRAIN, themembrane must be held back to thestep in the fleeced bonding flange. Applyunmodified thin-set mortar to the bondingflange using a 1/4" x 3/16" (6 mm x 4 mm)V-notched trowel or the Schluter ® -KERDItrowel, which features a 1/8" x 1/8" (3 mmx 3 mm) square-notched design. Firmlypress Schluter ® -KERDI into the mortar withthe flat side of the trowel to ensure 100%coverage and a watertight seal. When usingthe stainless steel KERDI-DRAIN bondingflange, KERDI is adhered to the flange withKERDI-FIX. The flange must be clean andfree of grease or other contaminants prior toKERDI-FIX application.Relevant industry standard guidelines forfloor drains with integrated bonding flangeinclude method B422 in the Tile Councilof North America’s (TCNA) Handbookfor Ceramic Tile Installation and Method326DR in the Terrazzo, Tile and MarbleAssociation of Canada (TTMAC) SpecificationGuide 09300 Tile Installation Manual.Please contact Schluter ® -Systems for theSchluter ® Shower System installation videoand KERDI-DRAIN data sheet.Notes:1) For complete installation guidelines andwarranty criteria for Schluter ® -KERDI inshowers, steam showers, and bathtubsurrounds, please contact Schluter ® -Systems for a copy of the Schluter ® -Shower System Installation Handbook(USA: 800-472-4588; Canada: 800-667-8746), or download it from ourwebsite at www.schluter.com.2) Various configurations of the Schluter ® -KERDI-DRAIN are listed by UPC® (IGC195-2004), CSA (B79-94), and NSF(SE AD 130-007 and SE AD 130-0011).
