Schluter®-Shower System Installation Handbook 2019 Bonded Waterproofing System for Tiled Showers, Steam Showers, Steam Rooms, and Bathtub Surrounds Schluter -Shower System ® Bonded Waterproofing System for Tiled Showers, Steam Showers, Steam Rooms, and Bathtub Surrounds Ceramic and stone tiles are durable, easy to maintain, and hygienic, representing the ideal surface coverings, particularly in wet areas such as showers and bathtub surrounds. These coverings are not inherently waterproof, however, and must be installed in conjunction with a waterproofing system that effectively manages moisture to protect moisture-sensitive building materials and control mold growth. The Traditional Tiled Shower System The traditional method for installing tiled showers is time and labor intensive and creates a “water in/water out” system. First, a mortar bed is sloped to the weep holes in the drain. The waterproofing membrane, called a pan liner, is placed over this “pre-slope” and clamped into the drain. Pan liners do not allow for the direct application of ceramic or stone tile. Thus, another mortar bed must be installed to provide load distribution and a bonding surface for the floor tile. Finally, a moisture barrier typically must be included behind the solid backing on the walls (e.g., mortar, cement backerboard, etc.) and lapped over the pan liner to protect the wall cavities from moisture penetration and divert that moisture into the pan. 4 3 1 2 Contrary to popular belief, the tile covering itself is not waterproof. Moisture will infiltrate the mortar bed and solid backing on the walls. This moisture must percolate through the mortar bed to the sloped pan liner and exit through the weep holes in the drain. With regular use of the shower the mortar bed can remain saturated, particularly if pre-slope installation is ignored or the weep holes become clogged, thus increasing the potential for efflorescence and mold growth within the system. 1 Pre-slope 2 Weep holes 3 Pan liner 4 Mortar bed Schluter®-Shower System 3 1 2 1 Schluter®-KERDI-DRAIN 2 Sloped mortar bed or Schluter®-KERDI-SHOWER-T/TS/-TT prefabricated foam tray 3 Schluter®-KERDI waterproofing membrane The Schluter®-Shower System is an integrated family of products that creates a “sealed” system. First, the Schluter®-KERDI-DRAIN is installed in conjunction with either a sloped mortar bed or the Schluter®-KERDI-SHOWER-T/-TS/-TT prefabricated foam trays. The KERDI-DRAIN provides a simple and secure connection to the Schluter®-KERDI waterproofing membrane at the top of the assembly via the unique integrated bonding flange. Unlike shower pan liners in traditional assemblies, KERDI is a bonded waterproofing membrane that allows for the direct application of tile with thin-set mortar. KERDI is bonded to the mortar bed or tray and the surface of the KERDI-DRAIN’s integrated bonding flange. In addition, KERDI is installed over the solid backing (e.g., gypsum board, cement backerboard, etc.) on walls, creating a fully waterproof and vaportight enclosure. The resulting assembly provides superior moisture management as it does not permit moisture to penetrate into the mortar bed or solid backing, allowing the assembly to dry completely between uses. The integrated Schluter®-Shower System eliminates leaks, reduces the potential for efflorescence and mold growth in the system, and dramatically reduces total installation time to ensure success and make shower installation easier than ever. Schluter®-Systems’ written installation instructions shall have precedence over referenced industry standard guidelines and installation procedures insofar as referenced information may contain overlapping or conflicting requirements. Type, thickness, and format of the tile or stone surface covering must be suitable for the intended application.

Do not use sawn lumber curbs on concrete subfloors subject to moisture migration. ® ® Requirements Plywood, OSB, or concrete subfloor must be clean, even, and load bearing. For wood substrates, subfloor/underlayment configuration according to detail DH-W16-T, DH-W19-T, DH-W24-T, or DH-W-S. For curbless applications: Recessing the floor of a bathroom must be done in a way that preserves the structural integrity and safety of the construction. This may require the services of a qualified design professional (e.g., architect, engineer, etc.). Solid backing – gypsum wallboard, cementitious backer unit, fiber-cement underlayment, fiber-reinforced water-resistant gypsum backerboard/underlayment, coated glass mat water-resistant gypsum backerboard, Portland cement mortar bed, concrete, or masonry. Minimum KERDI-BOARD thickness – 1/2" (12.5 mm) for studs spaced at 16" (40.6 cm) o.c. and 3/4" (19 mm) for studs spaced at 24" (61.0 cm) o.c. KERDI-BOARD shall be fastened to wood or metal framing with appropriate screws (i.e., coarse thread wood screw for wood studs and self-tapping for metal studs) and corresponding KERDI-BOARD-ZT washers. Screws must reach a depth of at least 3/4" (20 mm) in wood studs and 3/8" (10 mm) in metal studs. Maximum allowable on-center fastener spacing is 12" (30 cm) for walls and 6" (15 cm) for ceilings. KERDI or KERDI-BOARD shall be installed up to the height of the showerhead at minimum. In enclosed shower areas, install KERDI waterproofing membrane on all surfaces, including the ceiling, door jambs and the door header. Any protrusions through the KERDI or KERDI-BOARD (e.g., showerhead, mixing valve, etc.) must be treated with KERDI-SEAL-PS/-MV seals, KERDI-FIX or suitable sealant. Base – KERDI-SHOWER--T/-TS/-TT/-LT/-LTS or Portland cement mortar bed. Ramp – KERDI-SHOWER-SR or Portland cement mortar bed. Curb – KERDI-SHOWER-SC, KERDI-BOARD-SC, KERDI-BOARD, concrete, masonry block, or sawn lumber sheathed with solid backing (see above). Bench – KERDI-BOARD-SB, KERDI-SHOWER-SB, KERDI-BOARD, concrete, masonry block, or sawn lumber sheathed with solid backing (see above). All horizontal surfaces (e.g., benches, curbs, window sills, shelves, etc.) must be sloped toward the shower drain. This can be done by sloping the substrate or the tile. KERDI-DRAIN/-LINE shall be properly supported. Additional thin-set mortar may be needed to bed the KERDI-DRAIN for this detail. KERDI-DRAIN/-LINE shall be connected to the waste line; use ABS cement for ABS drains, PVC cement for PVC drains, a no-hub coupling for stainless steel drains with no-hub outlets, and thread sealing compound or tape for stainless steel drains with threaded outlets. When using the stainless steel KERDI-DRAIN bonding flange, use KERDI-FIX to bond KERDI to the drain. DITRA-HEAT heating cables must be installed in the DITRA-HEAT or DITRA-HEATDUO membrane. KERDI must be installed over the heating cables and DITRA-HEAT/DUO in the shower. Due to the installation of the DITRA-HEAT membrane on top of the shower tray, it is necessary to raise the height of the KERDI-DRAIN/LINE. Installation of DITRA-HEAT membrane on the substrate under the detachable center section for KERDI-DRAIN or under the KERDI-LINE channel body support will provide the proper height adjustment. When a curb is used, the heating cables must be installed over the curb in a 3/4" wide x 1/4" deep routed section and encased in thin-set mortar. DO NOT install the heating cable under the curb or go through the curb, as this could cause damage to the heating cable and curb. After the heating cable is installed, apply KERDI over the routed section of the KERDI-BOARD-SC curb. A dedicated heating cable is recommended in the shower area to allow for simple disconnection without an impact on the bathroom floor heating in the event that the shower heating cable is damaged. Multiple heating cables may be installed on a single thermostat, up to the 15 amp limit. Heating cables must be installed 3 studs from the edge of the KERDI-LINE flange and 2 studs from the edge of the KERDI-DRAIN flange. Safety Repairs to the DITRA-HEAT heating cable in the shower may not be approved. Verify with the local inspector or authority having jurisdiction (AHJ). Flood testing the shower is recommended before re-tiling. Heating cable factory splice (i.e., cold lead splice) must not be installed in the shower area. Substrate Preparation Verify that subfloor panels and solid backing are properly fastened to framing members. Any leveling of the subfloor must be done prior to installing KERDI-SHOWER-T/TS/-TT/-LT/-LTS/-SC/-SB/-SR, KERDI-BOARD-SC/-SB, DITRA-HEAT, and DITRAHEAT-DUO membranes. Solid Backing Materials Gypsum wallboard – ASTM C1396/C1396M Cementitious backer unit – ANSI A118.9 or ASTM C1325 Fiber-cement underlayment – ASTM C1288 Fiber-reinforced water-resistant gypsum backerboard/underlayment – ASTM C1278 Coated glass mat water-resistant gypsum backerboard – ASTM C1178 Portland cement mortar – ANSI A108.1B Concrete Masonry Setting and Grouting Materials Unmodified thin-set mortar – ANSI A118.1 Grout – ANSI A118.3, A118.6, A118.7 Installation Specifications Solid backing panels – follow manufacturer’s instructions Portland cement mortar bed – ANSI A108.1B Tile – ANSI A108.5 Grout – ANSI A108.6, A108.10 Other Considerations Acceptance of electric floor warming in a shower and this detail must be verified by the local inspector or authority having jurisdiction (AHJ). KERDI is required on top of DITRA-HEAT installations in the shower. Schluter Systems chooses to be conservative and to ensure everything is protected. Note: DITRA-HEAT-E-HK heating cables are rated for wet applications per CAN/CSAC22.2 No.130-03.DITRA-HEAT membranes have been found to meet or exceed the requirements of ANSI A118.10. Curbless tiled showers rely on the slope of the floor to effectively contain water in the immediate shower area and direct water to the drain. Given the wide range of potential configurations, it isn’t possible to address them all in this Handbook. For curbless applications: waterproofing must be installed in all areas subject to water exposure. Schluter -SHOWERPROFILE-WS/-WSK system profiles can be used to form a splashguard at the entrance of curbless showers. Various building codes and other sources, such as the Americans with Disabilities Act, include specific requirements for disabled access in public buildings and must be consulted when applicable. Areas of interest may include degree of slope, clearance, and supporting structures such as grab bars. Shower grab bars must be anchored in the structure or solid blocking behind KERDIBOARD. When KERDI-SHOWER-T/-TS/-TT/-LT/-LTS tray dimensions do not match the dimensions of the shower compartment, the tray may be cut or extended with dry pack mortar. When KERDI or KERDI-BOARD and tile are installed on the ceiling, the solid backing and fasteners must be able to support the load of the tile and setting and grouting materials. A water test is strongly recommended before setting tile to verify a successful installation. Wait 24 hours minimum after the membrane installation is complete to allow for final set of thin-set mortar and ensure waterproof performance at seams and connections. Refer to local plumbing codes for any specific requirements in your area. For curbless showers a temporary dam (e.g., a 2x4 and silicone sealant, plastic sheeting and sand, etc.) must be provided at the threshold to perform the water test. Schluter -Systems profiles may be used to finish and protect outside corners and eliminate the use of sealant at inside corners.

Recessing the floor of a bathroom must be done in a way that preserves the structural integrity and safety of the construction. This may require the services of a qualified design professional (e.g., architect, engineer, etc.). Solid backing – gypsum wallboard, cementitious backer unit, fiber-cement underlayment, fiber-reinforced water-resistant gypsum backerboard/ underlayment, coated glass mat water-resistant gypsum backerboard, Portland cement mortar bed, concrete, or masonry. Base – KERDI-SHOWER-T/-TS/-TT/-LT/-LTS or Portland cement mortar bed. Ramp – KERDI-SHOWER-SR or Portland cement mortar bed. Bench –KERDI-BOARD-SB, KERDI-SHOWER-SB, KERDI-BOARD, concrete, masonry block, or sawn lumber sheathed with solid backing (see above). KERDI-DRAIN/-LINE shall be properly supported. KERDI-DRAIN/-LINE shall be connected to the waste line; use ABS cement for ABS drains, PVC cement for PVC drains, a no-hub coupling for stainless steel drains with no-hub outlets, and thread sealing compound or tape for stainless steel drains with threaded outlets. Minimum KERDI-BOARD thickness – 1/2" (12.5 mm) for studs spaced at 16" (40.6 cm) o.c. and 3/4" (19 mm) for studs spaced at 24" (61.0 cm) o.c. KERDI-BOARD shall be fastened to wood or metal framing with appropriate screws (i.e., coarse thread wood screw for wood studs and self-tapping for metal studs) and corresponding KERDI-BOARD-ZT washers. Screws must reach a depth of at least 3/4" (20 mm) in wood studs and 3/8" (10 mm) in metal studs. Maximum allowable on-center fastener spacing is 12" (30 cm) for walls and 6" (15 cm) for ceilings. KERDI or KERDI-BOARD shall be installed up to the height of the showerhead at minimum. In enclosed shower areas, install KERDI or KERDI-BOARD on all surfaces, including the ceiling, door jambs and the door header. KERDI, DITRA or DITRA-HEAT shall be installed in all floor areas subject to water exposure (i.e., wet area and drying area). Floor/wall connections shall be sealed with KERDI-BAND. Any protrusions through the KERDI or KERDI-BOARD (e.g., showerhead, mixing valve, etc.) must be treated with KERDI-SEAL-PS/-MV seals, KERDIFIX or suitable sealant. When using the stainless steel KERDI-DRAIN bonding flange, use KERDI-FIX to bond KERDI to the drain. All horizontal surfaces (e.g. benches, window sills, shelves, etc.) must be sloped toward the shower drain. This can be done by sloping the substrate or the tile. Substrate Preparation Verify that subfloor panels and solid backing are properly fastened to framing members. Any leveling of the subfloor must be done prior to installing KERDI-SHOWER-T/-TS/-TT/-LT/-LTS/-SB/-SR and KERDI-BOARD-SB prefabricated substrates. Installation Specifications Solid backing panels – follow manufacturer’s directions Portland cement mortar bed – ANSI A108.1B Tile – ANSI A108.5 Grout – ANSI A108.6, A108.10 Other Considerations If installing the KERDI-SHOWER-TT thin tray, the installation of a 5/8" or 3/4" plywood/OSB on top of a wood subfloor and Schluter -DITRA-HEAT or Schluter -DITRA-XL is suggested to create a curbless shower application. Due to the additional height, be sure to check the transition height at the bathroom doorway. Curbless tiled showers rely on the slope of the floor to effectively contain water in the immediate shower area and direct water to the drain. Given the wide range of potential configurations, it isn’t possible to address them all in this Handbook. Waterproofing must be installed in all areas subject to water exposure. Install KERDI over mortar beds and Schluter prefabricated EPS foam substrates. Use the DITRA or DITRA-HEAT uncoupling membrane over plywood/OSB or concrete subfloors. All seams are sealed using KERDI-BAND. Please refer to the Schluter -DITRA or Schluter -DITRA-HEAT Installation Handbooks for complete details and warranty criteria. If KERDI-LINE is placed at shower entrance, it is recommended that grate assembly A, Pure, or the covering support (D) is chosen and that the drainage openings span the maximum width of the entrance to limit potential overflow; secondary drainage (e.g., KERDI-DRAIN) may be required in the drying area. Schluter -SHOWERPROFILE-WS/-WSK system profiles can be used to form a splashguard at the entrance of curbless showers. See page 35. Various building codes and other sources, such as the Americans with Disabilities Act, include specific requirements for disabled access in public buildings and must be consulted when applicable. Areas of interest may include degree of slope, clearance, and supporting structures such as grab bars. Shower grab bars must be anchored in the structure or solid blocking behind KERDI-BOARD. When KERDI-SHOWER-T/-TS/-TT/-LT/-LTS tray dimensions do not match the dimensions of the shower compartment, the tray may be cut or extended with dry pack mortar. When KERDI or KERDI-BOARD and tile are installed on the ceiling, the solid backing and fasteners must be able to support the load of the tile and setting and grouting materials. A water test is strongly recommended before setting tile to verify a successful installation. Wait 24 hours minimum after the membrane installation is complete to allow for final set of thin-set mortar and ensure waterproof performance at seams and connections. Refer to local plumbing codes for any specific requirements in your area. For curbless showers a temporary dam (e.g., a 2x4 and silicone sealant, plastic sheeting and sand, etc.) must be provided at the threshold to perform the water test. Schluter -Systems profiles may be used to finish and protect outside corners and eliminate the use of sealant at inside corners; see page 37.

CURBLESS SHOWERS Accessibility and style As our population ages, there is increasing demand for accessible living spaces. Tiled showers typically feature curbs to retain water in the stall, which can make entry difficult for those with limited mobility, including individuals who need the assistance of wheelchairs. Curbless tiled showers eliminate the use of a curb and rely on the slope of the floor to keep water inside the stall, thus improving accessibility. These showers have also become increasingly popular for their aesthetic benefits, as they can integrate seamlessly with surrounding tiled surfaces to enhance an already luxurious environment. DESIGN AND INSTALLATION CONSIDERATIONS The Schluter®-Shower System provides a simple and effective means of waterproofing curbless installations. The key to this is that the KERDI waterproofing membrane is topically applied. Once the slope to the drain is established, KERDI and tile are installed, thus minimizing the thickness of the assembly. Curbless tiled showers rely on the slope of the floor to effectively contain water in the immediate shower area and direct water to the drain. Given the wide range of potential configurations, it isn’t possible to address them all in this Handbook. However, the following guidelines will assist in planning any curbless installation. Ideally, the floor will be recessed before installing a sloped mortar bed or the KERDI-SHOWER prefabricated shower trays to allow an even transition at the door threshold. This can be relatively straightforward in new construction and can also be accomplished in renovations. When recessing the floor is not an option, it is necessary to provide a ramp up into the shower area. The KERDI-SHOWER prefabricated trays and ramp can be useful tools in such applications as well. Please note that recessing the floor of a bathroom must be done in a way that preserves the structural integrity and safety of the construction. This may require the services of a qualified design professional (e.g., architect, engineer, etc.). Waterproofing must be installed in all areas subject to water exposure. Ideally, the entire floor is protected. Install KERDI over mortar beds and Schluter -Systems prefabricated EPS foam substrates. Use the DITRA or DITRA-HEAT uncoupling membrane over plywood/OSB or concrete subfloors. All seams are sealed using KERDI-BAND. The SHOWERPROFILE-WS/-WSK splash guard profiles may be used at the entrance of curbless showers. Secondary drainage may be required in the drying area for any overflow. Please see detail K-SHBF on page 12 for further discussion. ® Note on Accessibility Guidelines: Various building codes and other sources, such as the Americans with Disabilities Act, include specific requirements for disabled access in public buildings and should be consulted when applicable. Areas of interest may include degree of slope, clearance, and supporting structures such as grab bars. CURBLESS SHOWERS — Accessibility and style 35 THE WATERPROOF BATHROOM Security and utility Bathrooms are a primary focus of today’s building and remodeling projects and are becoming more and more luxurious, complete with steam showers, oversized bathtubs, and the latest in fixtures and lighting. As such, tiled showers, bathtub surrounds, floors, walls, and vanities are in high demand. Tile and stone are beautiful, durable, and available in a wide range of formats, colors, and textures, allowing limitless design options. Tile and stone offer unmatched utility and high-end appeal, making them the ideal surface coverings for bathrooms. Given the substantial investments made in these projects and nature of use, long-term durability is a high priority. KERDI Waterproofing is the foundation of successful tiled bathrooms. Moisturesensitive construction materials (e.g., wood framing, plywood and OSB sheathing, gypsum wallboard, etc.) are common in the North American building environment and must be protected in wet areas. Wet areas also bring the potential for mold growth if effective moisture management is not provided. The key to mold control is moisture control. In addition to showers and tub surrounds, bathroom floors surrounding these fixtures are routinely subjected to water exposure during use. Bathroom floors may also, through unexpected circumstances, become exposed to significant amounts of water; for example, an overflowed toilet or ruptured sink supply, which can result in flooding. Waterproofing these floors can save an owner from replacing the tile assembly and substructure in the event of a leak. Schluter -Systems offers simple and effective solutions to protect moisture-sensitive substrates, prevent mold growth, and preserve the integrity of the tiled surface throughout the bathroom. The Schluter®-Shower System is an integrated family of products that together form a fully bonded, watertight assembly for tiled showers and bathtub surrounds. DITRA is an uncoupling membrane that protects the tiled floors from damage by neutralizing differential movement stresses between the substrate and tile and provides reliable waterproofing. Since both of these systems are based on topically-applied, bonded waterproof membranes, they can be combined simply and easily to provide waterproofing throughout the bathroom. ® DITRA Floors can be made fully waterproof with DITRA. Since the membrane is made of waterproof polyethylene, the only extra step necessary is to seal the seams and floor/wall connections with KERDI-BAND. The same practice is used to integrate the DITRA with the KERDI used to waterproof the shower or tub surround. The result is a comprehensive waterproofing system that protects against moisture penetration. For added luxury, the DITRA-HEAT electric floor warming system with integrated uncoupling technology ensures that floors are both comfortable, and resistant to cracked tiles and grout. Cables can be placed wherever heat is desired for customized heating zones, and no leveling compounds are required, making for a quick and easy installation.

Exposed tile edges, however, are unsightly and prone to cracking and chipping. While ceramic trim pieces such as bullnose or quarter round have traditionally been used to finish and protect tile edges at the outside corners and perimeters of an installation, ceramic trim availability can be limited, particularly in imported tile lines, which can in turn limit overall tile selection. Ceramic cove base represents a neat, hygienic method for treating transitions at inside corners by providing a curved surface that prevents the collection of dirt and is easy to clean. However, the limited availability of ceramic trim pieces has resulted in the use of sealant and caulk to treat such transitions. These joints must be continually maintained throughout the life of the installation. This may include replacing the joints, which requires cutting the sealant out and possibly compromising the waterproofing membrane. Finishing and edge protection Maintenance-free inside corners Schluter -Systems offers various finishing and edge-protection profiles for outside corners and other tiled edges that can be used with any field tile, thus reducing dependence on ceramic trim and increasing design options. These profiles are available in a wide range of materials and finishes such as stainless steel, anodized aluminum, brass, and colored PVC to produce a variety of looks, including bold contrasts, discreet color matches to the grout, and complements to plumbing fixtures. Schluter -Systems offers various cove-shaped profiles to address the need to finish inside corners. These profiles can be used with any field tile to produce permanent, easy to clean, and maintenance-free floor/wall transitions and inside wall corners. ® Schluter -QUADEC Provides a symmetrically rounded edge for a smooth design.

PROFILES — Details make the difference 37 TILE SELECTION CONSIDERATIONS Discussion of different tile types in shower applications The Schluter -Shower System is an integrated family of products that creates a sealed system for showers, steam showers, steam rooms, and bathtub surrounds. The Schluter -KERDI/-KERDI-DS membranes and Schluter -KERDI-BOARD substrates are waterproof and provide a bonding surface for tile coverings. Typical covering materials include ceramic, porcelain, and natural stone tiles. The following information is intended to be used as input for tile selection in shower applications. ® ® ® Ceramic and Porcelain In general, ceramic and porcelain tiles are excellent choices for shower applications. They are not adversely affected by moisture and are easily cleaned. Furthermore, they can be installed using unmodified thin-set mortar within the Schluter -Shower System. However, some specific categories of these materials require special consideration. ® Mounted Mosaic Tiles Schluter Systems does not specify a minimum tile format for use over the KERDI-SHOWER series of prefabricated foam trays, but when using small tiles with heavy loads a mortar base is recommended. Mosaic tile are typically mounted and sold as sheets for ease of handling and installation. There are various methods used to mount the tiles, some of which can present installation or application challenges. Back-mounted and edge-mounted tile assemblies may have paper, mesh, resin, polyurethane, or other bonding material on the back or edges of each tile, which becomes part of the tile assembly. In some cases, the adhesive used to mount the tiles is moisture sensitive and may lead to debonding once the shower is put into service. According to the TCNA Handbook for Ceramic, Glass, and Stone Tile Installation, mounted tile assemblies must feature sufficient exposure of the bonding surface of the tile to allow for 95% contact with the setting material in wet areas. Confirm with the tile manufacturer that the back- or edge-mounted tile is suitable for use in wet areas and never use paper back-mounted mosaics in shower applications. Face-mounted tiles may use a clear film that is removed after final set or paper that is removed during the installation process before adjustments are made and final set is reached. In general, this approach is superior because the back of the tile is in full contact with the bond coat. Pebbles Pebble tiles have been used on shower floors for years, but due to their irregular shape there are some items to address with installation. For example, rounded pebble tiles can create barriers to drainage in showers since the grout is typically not flush with the surface of the pebbles. Maintaining sufficient slope for drainage is essential, perhaps even in excess of the typical 1/4" per foot. Rounded pebble tiles may also require a relatively thick bond coat to ensure proper coverage and bond to the shower base. Pebble tiles with flat surfaces can be easier to install with respect to the issues described above. Grout joints in pebble tile applications are typically wider than those in square or rectangular tile applications. Follow the tile and setting material manufacturer’s instructions for grout selection. Large Porcelain Tile Panels Large porcelain tile panels are growing in availability and interest in North America. Some of these tile panels feature resin or urethane backings, which require special setting materials, such as modified thin-set mortars or epoxy adhesives. Panel manufacturers may require modified thin-set mortars to install panels without backings as well. Often, these manufacturers have tested and recommend specific mortars to install the panels, not just any mortar within a category or meeting an ANSI specification. Contact the panel manufacturer and setting material manufacturer to obtain a recommendation for a specific setting material to install the panel over a bonded waterproofing system. 38 TILE SELECTION CONSIDERATIONS — Discussion of different tile types in shower applications Natural Stone Natural stone tiles are a product of nature and have various characteristics that provide beauty and features not found in manufactured tile products. According to the Dimension Stone Design Manual published by the Marble Institute of America (MIA), selection of stone for a shower is critical since the impact of water on certain stones (e.g. polished marble, limestone, etc.) may cause deterioration (e.g., surface dulling, warpage, etc.) over time. Selection of a dense, moistureresistant stone will provide the best results in a shower. Moisture-Sensitive Stone According to the TCNA Handbook for Ceramic, Glass, and Stone Tile Installation, many greencolored marbles and serpentines warp when exposed to water, including the water mixed in cement-based setting materials. Such stones may not be suitable for use in shower applications and/or may require special setting materials. Schluter Systems recommends consulting with the stone supplier to help determine if a particular material is suitable for use in wet areas and that a 100% solids epoxy tile adhesive is used to install the stone. Fiberglass Mesh Reinforced Stone According to the TCNA Handbook for Ceramic, Glass, and Stone Tile Installation, many stone products have mesh reinforcement attached to the back surface of the tile, typically using an epoxy or polyester-based adhesive. Cement-based setting materials will not bond to these backings and Schluter Systems recommends using a 100% solids epoxy tile adhesive to install the stone. Mounted Mosaic Stone Tiles Similar challenges as ceramic and porcelain mounted mosaic tiles. See mounted mosaic tiles section under ceramic and porcelain tile. Glass Glass tile is available in a wide variety of types (e.g., cast, fused, sintered, etc.) and formats. Entire tiles may be imbued with color, while in other cases layers of clear glass are combined with different backings of different color that show through. Some backings are dusted with quartz (sand) to provide texture to improve bonding characteristics. However, other backings are smooth and glossy, making it difficult to achieve a bond. Furthermore, some glass tile manufacturers do not recommend use of their clear glass tile directly over bonded waterproofing membranes. They want the substrate to be able to wick water away from the bond coat (e.g., CBU or mortar walls) to help maintain a uniform bond coat appearance. Confirm with the glass tile manufacturer that the glass tile is suitable for use in wet areas and can be installed directly over a bonded waterproofing membrane such as KERDI. Check with the glass tile manufacturer and setting materials manufacturer for setting materials recommendations. Mounted Mosaic Glass Tiles Similar challenges as ceramic and porcelain mounted mosaic tiles. See mounted mosaic tiles section under ceramic and porcelain tile. TILE SELECTION CONSIDERATIONS — Discussion of different tile types in shower applications 39 THIN-SET FACTS Discussion on thin-set mortars and Schluter®-KERDI installations Schluter -Systems offers thin-set mortars designed for use with Schluter membranes and boards. All Schluter -Systems’ thin-set mortars, including the ALL-SET and FAST-SET modified varieties, can be used to set tile over Schluter -DITRA, DITRA-HEAT, KERDI, KERDI-BOARD non absorptive substrates. If Schluter thin-set mortars are not used, we require unmodified thin-set mortar when setting ceramic or porcelain tile over KERDI. ® ® ® TM TM ® ® QUESTION: Should a latex-modified thin-set mortar or an unmodified thin-set mortar be used to install Schluter®-KERDI? ANSWER: The type of bonding mortar used to apply KERDI must be suitable for the substrate and mechanically anchor the fleece on the KERDI. For all the substrates listed in this Handbook (e.g., gypsum board, cement backerboard, etc.), Schluter SET , ALL-SET , FAST-SET or an unmodified thin-set mortar is recommended. When installing KERDI with unmodified thin-set mortar over particularly dry and porous substrates, it is recommended to wet the substrate first, in order to help prevent premature drying or skinning of the thin-set mortar. Schluter SET , ALL-SET , FAST-SET or an unmodified thin-set mortar must be used to construct all KERDI seams to ensure watertight performance of the system. Learn more below. TM TM TM TM TM TM QUESTION: Can ceramic tile, including porcelain tile, be set on Schluter®-KERDI with unmodified thin-set mortar? ANSWER: YES. In general, we recommend it. Here’s why: Portland cement-based unmodified thin-set mortars are dependent on the presence of moisture for hydration in order to gain strength. Since KERDI is impervious, it does not deprive the mortar of its moisture. This allows the cement to properly hydrate, resulting in a strong, dense bond coat. In fact, after the mortar has reached final set (usually within 24 hours), unmodified thin-set mortars achieve higher strengths when cured in continually moist conditions. QUESTION: Can ceramic tile, including porcelain tile, be set on Schluter®-KERDI with latexmodified thin-set mortar? ANSWER: In general, We DON’T recommend it. Here’s why: Latex-modified mortars must dry for the polymers to coalesce and form a hard film in order to gain strength. When sandwiched between two impervious materials such as KERDI and ceramic tile, including porcelain tile, drying takes place very slowly through the open joints in the tile covering. [According to the Tile Council of North America's Handbook for Ceramic, Glass, and Stone Tile Installation, this drying period can fluctuate from 14 days to over 60 days, depending on the geographic location, the climatic conditions, and whether the installation is interior or exterior]. Therefore, extended cure times could be required before grouting if using modified thin-set mortars between KERDI and ceramic tile, including porcelain tile. If extended cure times were not observed, the results could be unpredictable. This is even more important to consider in wet areas such as showers, as there is the additional concern of latex leaching. QUESTION: How do I know if the thin-set mortar is modified or unmodified? ANSWER: In general, unmodified thin-set mortar is a blend of Portland cement, sand, and water retention agents that is mixed with water by the user. The applicable product standard for unmodified thin-set mortars is ANSI A118.1. Look for this standard on the packaging (e.g., product meets ANSI A118.1 when mixed with water). Unmodified thin-set mortar may also be referred to as dry-set mortar by the manufacturer. Modified thin-set mortars are similar to unmodified thin-set mortars, but include additional polymers such as latex. The additional polymers are introduced in either liquid or powder form. In the first case, the user mixes an unmodified or dry-set mortar powder with a liquid polymer additive instead of water. In the second case, the polymers are added by the manufacturer to the dry blend in powder form. The user then mixes the powder with water. The applicable product standards for modified thin-set mortars include ANSI A118.4 and ANSI A118.11. 40 THIN-SET FACTS — Discussion on thin-set mortars and Schluter®-KERDI installations QUESTION: Can Schluter ALL-SET and FAST-SET modified thin-set mortars be used to set tile over Schluter boards and membranes? TM TM ANSWER: Yes. All Schluter thin-set mortars, including the ALL-SET and FAST-SET DITRA-HEAT, KERDI, KERDI-BOARD non absorptive substrates. ® TM TM modified varieties can be used to set tile over DITRA, QUESTION: How is this possible? ANSWER: The key is predictability. Schluter Systems’ modified thin-set mortars have been specifically formulated to set and gain strength in a timeframe that fits typical installation practice, even when sandwiched between Schluter membranes or boards and porcelain tile. The proportions of cement, waterretention agents, polymers, and other components in the mixtures were balanced to ensure that extended dry times are not required. This was validated through both laboratory and practical testing. Now, the installer can select from either unmodified or modified thin-set mortar to install tiles within our systems according to his or her preference. ® QUESTION: Why did Schluter Systems change its position on thin-set mortar? ANSWER: We haven’t changed our position on thin-set mortar use within our systems. Developing our own setting materials has given us the ability to guarantee consistently positive results. And since we control the formulas, we can be sure no changes will be made that have a negative impact on setting times and strength gain in these environments. QUESTION: Does this mean I can use other manufacturers’ modified thin-set mortars to install tile over Schluter boards and membranes? ANSWER: No. Our position on thin-set mortar use within our systems in general has not changed. We have no control over the formulation of other manufacturers’ products and therefore cannot guarantee consistently positive results with their modified thin-set mortars. QUESTION: Can I still use other manufacturers’ unmodified thin-set mortars to install tile over Schluter boards and membranes? ANSWER: Yes. We still warrant the use of unmodified thin-set mortar meeting ANSI A118.1 to install tile within our systems because we have confidence in the performance of this product category. This is based on the science of cement hydration and years of positive testing and field experience. Please note, if Schluter thin-set mortars are used with Schluter membranes an extended system warranty is available. For full warranty details, please visit schluter.com/warranty. ® ® ADDITIONAL NOTES • Remember, all thin-set mortars have an acceptable temperature range that must be observed during application and curing. • Pre-mixed thin-set mortars and mastics are not suitable for use in conjunction with the Schluter -Shower System. ® THIN-SET FACTS — Discussion on thin-set mortars and Schluter -KERDI installations ® 41 TESTING, LISTINGS, & APPROVALS Products and system evaluation Schluter®-Systems is committed to providing reliable installation systems for tile and stone.

Mildew is another common term which refers to the type of fungi found growing on window sills and in bathrooms. Fungi are everywhere in our environment and are found both indoors and outdoors. However, the type and amount found in the home can be an important health issue. Understanding how to effectively control mold growth is very important. What is Mold? Fungi are different from plants and animals. Fungi cannot produce their own nutrients as plants do and reproduce differently than both plants and animals. Molds reproduce by making spores which travel through the air to deposit on surfaces. If the conditions are right for reproduction they can grow and continue to multiply. The filamentous parts of mold attach to nutrients and form networks called mycelia. It is these networks that are visible to us in the indoor environment. Molds come in a variety of colors, but we commonly see them as green or black. Over 1000 different species of mold have been identified in homes, but they are not all toxic to humans. Molds growing inside a home may release chemicals and spores and some may even produce mycotoxins. The chemicals released by fungi are called volatile organic compounds (VOC). For example, ethanol is a common VOC that is responsible for the distinctive musty or earthy odor associated with mold. Health Effects Mold can cause damage to building materials and may have adverse health effects on some individuals. The susceptibility of people to develop symptoms depends on the nature of the fungal material, genetic predisposition, age, state of health, and extent of exposure. Although there is insufficient evidence in the scientific community to determine with certainty the association between mold exposure and the effect on human health, it is of course recommended to control mold exposure in the home and workplace. Common health effects associated with exposure to mold are a variety of upper and lower respiratory tract symptoms: cough; nose, throat and eye irritation; rhinitis; sneezing; and wheezing. These symptoms are similar to allergies and associated with asthma. Mycotoxins are fungal metabolites that have a toxic effect on humans. Toxic effects are associated with symptoms such as fever, nausea, headaches, and skin irritations. Factors for Mold Growth Fungi need a source of moisture, organic material to serve as a source of nutrients, and a warm environment with a temperature range from 50 to 107 °F (10 to 42 °C) to grow. For most species of fungi, a neutral to acidic pH is preferred, with a high pH level indicating an alkaline environment that is generally not conducive to mold growth. Mold will reproduce in such conditions as long as moisture is present. Once the area is dry, the mold may stop reproducing but can continue to be allergenic to susceptible people. If moisture is reintroduced, the mold will again start the reproduction cycle and grow. Controlling Mold Growth As stated above, four conditions must be satisfied to support mold growth. 1. Mold spores 2. Food source (organic material) 3. Warm temperatures: 50 to 107 °F (10 to 42 °C) 4. Moisture Mold spores travel through the air indoors and outdoors and are impossible to eliminate. The use of organic materials in construction is common in today’s building environment. Examples include wood framing members (e.g., studs, joists, I-joists, and trusses), plywood or OSB subfloors, paper-faced gypsum boards on walls and ceilings, etc. Room temperature falls within the temperature range suitable for mold growth. Therefore, the control of moisture, including liquid water and water vapor, is the only viable method for controlling mold growth in the indoor environment. Showers are critical areas with respect to mold and moisture control. They are commonly exposed to thousands of gallons of water per year and high humidity levels. The tile covering alone will not prevent water and moisture penetration. As such, it is essential that an effective moisture management system be designed and installed properly to protect surrounding building materials and prevent mold growth. The traditional method for installing tiled shower assemblies creates a water in/ water out system. Since shower pan liners are placed below the mortar setting bed in these assemblies, moisture is allowed to saturate the mortar bed before exiting the system through the weep holes in the drain. When the pan liner is placed on a level substrate instead of a sloped surface, a relatively common error, moisture in the system will have no means to exit through the weep holes in the drain and the mortar bed will remain saturated for extended periods of time. The continued presence of moisture, combined with organic materials carried into the mortar bed by the rinse water, warm temperatures, and reduced pH as soluble salts are washed out of the mortar bed, increases the risk of mold growth within the system. The Schluter®-Shower System is an integrated family of products that creates a sealed system. KERDI is a bonded waterproof membrane that is installed on top of the mortar bed and solid backing on walls. Tile is installed directly over the membrane using thin-set mortar. The KERDI-DRAIN was designed specifically to ensure a simple and secure connection to bonded waterproof membranes, such as KERDI, at the top of the assembly rather than below it. The resulting assembly does not permit moisture penetration into the solid backing or mortar bed, thus limiting the amount of water behind the tile covering and allowing the shower to dry out between uses. Furthermore, KERDI is a vapor retarder that protects wall cavities from water vapor penetration. Thus, the Schluter®-Shower System provides superior moisture management and reduces the potential for mold growth within the system. Regardless of the system used to waterproof a tiled shower, it is important to provide adequate ventilation (e.g., exhaust fans) in the bathroom to effectively manage water vapor and reduce condensation on all bathroom surfaces. Further discussion and recommendations for mold remediation can be found in various sources, including the following. • “A Brief Guide to Mold, Moisture, and Your Home” – U.S. Environmental Protection Agency (EPA) • “Mold Remediation in Schools and Commercial Buildings” – U.S. Environmental Protection Agency (EPA) • “Mould Guidelines for the Canadian Construction Industry” – Canadian Construction Association MOLD — The importance of mold control 43 VAPOR The importance of water vapor management Why is water vapor management important? It is important to consider that water exists as both liquid and vapor in showers, and must be managed in both forms. The prime example of this is the steam shower. Steam showers that are not designed to manage water vapor have caused mold growth in wall cavities, rot in wood framing, and damage to moisture-sensitive wall coverings on the opposite side of the stud cavities. Do all waterproofing membranes manage water vapor? The ANSI A118.10 standard for bonded waterproof membranes was developed to provide a framework for determining the suitability of these products to serve as barriers to liquid water only. As such, the standard does not include a minimum criterion to establish the ability of products to limit vapor transmission. Thus, simply selecting a membrane that meets the requirements of the ANSI A118.10 standard for a steam shower application is not enough. The ability of the product to limit vapor transmission must be considered as well. How can I identify a waterproofing membrane that manages water vapor? Water vapor permeance is a measure of how quickly water vapor is transmitted through a material and can be determined according to the ASTM E96 Standard Test Method for Water Vapor Transmission of Materials. The higher the vapor permeance, the less effective a material is at slowing vapor transmission. There is no universal requirement for vapor permeance of membranes in the building industry. The environmental conditions (i.e., differences in temperature and relative humidity), building materials, etc., and relevant field experience will determine the appropriate membrane performance for a given application. The consensus within the tile industry in North America has been that a vapor permeance of 1.0 perm or less will manage vapor effectively in showers and intermittent use steam shower applications. The TCNA Handbook for Ceramic, Glass, and Stone Tile Installation and the TTMAC Specification Guide 09 30 00 Tile Installation Manual specify a water vapor permeance of 0.5 perms or less for bonded waterproofing membranes used in continuous use steam rooms (e.g., those found in health clubs, spas, etc.) when tested using the desiccant method at 100°F (38°C) and 90% RH. Does the Schluter -Shower System manage water vapor? ® Schluter -Systems has tested the various options within the Schluter -Shower System for moisture management, including KERDI, KERDI-DS, and KERDI-BOARD in the more aggressive conditions referenced above. The table below summarizes Schluter -Systems' recommendations for the use of these products and respective water vapor permeance values. ® ® ® Product KERDI KERDI-DS KERDI-BOARD 1 2 Recommended Applications Showers, intermittent use steam showers, and bathtub surrounds Continuous use steam rooms Showers, intermittent use steam showers, and bathtub surrounds Water Vapor Permeance (perms) 0.90 0.19 0.36 1 2 Tested according to ASTM E96, using the desiccant method at 100°F (38°C) and 90% RH 1/2" – 12.5 mm-thick KERDI-BOARD tested While the water vapor permeance of KERDI-BOARD meets the water vapor permeance recommendations for continuous use steam rooms in tile industry standard guidelines, Schluter -Systems has chosen to require the KERDI-DS membrane for these demanding applications in an effort to be conservative and provide the best possible solution for our customers. ® Thus, the Schluter -Shower System has solutions that provide superior moisture management for virtually any tile application. ® 44 VAPOR — The importance of water vapor management PRODUCT & ORDERING INFO Ordering information for the Schluter®-Shower System and DITRA components outlined in this Handbook is located below.

It consists of an extruded polystyrene foam panel, with a special reinforcement material on both sides and fleece webbing for effective anchoring in thin-set mortar. The boards are simply cut to size with a utility knife. The gridlines, which are printed on the surface, are helpful for neat and quick cuts and installation. Tiles can be installed directly over KERDI-BOARD using the thin-set method. Schluter -KERDI-BOARD ® Additional panels and accessories Please refer to our Illustrated Price List for details.

ESR-2467 and PMG-1204). DITRA is a pressure-stable polyethylene uncoupling membrane, vacuum-formed in a cutback grid design, with an anchoring fleece laminated to its underside. DITRA is 1/8" (3 mm) in height. DITRA-XL is 5/16" (7 mm) in height. DITRA-HEAT is a polypropylene membrane with a cut-back stud structure and an anchoring fleece laminated to the underside. The matting is 1/4" (5.5 mm) in height. DITRA-HEAT-DUO offers the same functions as DITRA-HEAT, but features a thicker bonding fleece that adds sound control and thermal break. The matting is 5/16" (8 mm) thick. The thermal break fleece reduces heat loss to the substrate to improve floor warming response time. The stud structure is specifically designed to secure DITRA-HEAT-E-HK electric floor heating cables.

In order to extend warranty coverage for Schluter DITRA or DITRA -XL uncoupling membranes, Schluter -Shower System, Schluter KERDI or KERDI -DS waterproofing membranes, or Schluter DITRA-HEAT or Schluter DITRA-HEAT-DUO uncoupling membrane to lifetime coverage under this Lifetime Thin-Set System Extended Limited Warranty, Owner must complete and submit the Thin-Set System Registration to Schluter Systems, available at www.schluter.com, or submit proof of purchase and installation information (including installation date, installer’s name and address) to Schluter Systems at the address provided hereafter within ninety (90) days of installation. 1 ® ® ® ® ® ® ™ ® ® ® ™ For the purposes of this Limited Warranty, a “Thin-Set System” is defined as Schluter DITRA or DITRA -XL uncoupling membranes, Schluter -Shower System, Schluter KERDI -BOARD within a Schluter -Shower System, Schluter KERDI or KERDI -DS waterproofing membranes, or Schluter DITRA-HEAT™ or Schluter DITRA-HEATDUO™ uncoupling membrane installed with Schluter SET , Schluter ALL-SET , or Schluter FAST-SET thin-set mortar; “Owner” is defined as the original end user of the property in which a Thin-Set System is installed; “Lifetime” is defined as that period of time that the original Thin-Set System installation remains unchanged and under the ownership of the Owner; “Residential” applications are defined to include Thin-Set System installations in single family detached residential dwellings; and “Commercial” applications are defined to include Thin-Set System installations in multi-family residential dwellings (e.g., apartments, condominiums, cooperatives, and timeshares). ThinSet System installations in public places, commercial establishments and other applications may be afforded lifetime coverage under this Limited Warranty on a case by case basis as determined by the Schluter Systems Technical Services Director. ® ® ® ® ™ ® ® ® ® ® ™ ® ® ® ™ This Limited Warranty is only applicable to installations in the United States of America and Canada. Schluter Systems is not responsible or liable under any circumstances for determining the suitability of a Thin-Set System for the Owner’s intended purpose. It is the responsibility of the Owner to consult with an experienced and professional installer to ensure the suitability of a Thin-Set System, subfloor/substrate and all building materials in the installation and that the Written Materials are followed properly. RESOLUTION: If a Thin-Set System is installed and used in accordance with the terms and conditions as described hereinabove and such Thin-Set System is proven defective within the applicable warranty term, the Owner’s exclusive remedy and the sole obligation of Schluter Systems, at its election, shall be to (a) reinstall or replace the failed portion of the Thin-Set System or (b) pay an amount not to exceed the original square foot cost of the installation of the Thin-Set System verified to be defective. Due to conditions beyond the control of Schluter Systems (e.g., color and shade availability, discontinuation, normal wear and tear), Schluter Systems cannot guarantee or warrant an exact match to the specific tile, stone, or other flooring materials used in the original installation. In such event, substantially similar materials may be substituted. EXCLUSIONS FROM COVERAGE: This Limited Warranty excludes and in no event shall Schluter Systems have any liability for any indirect, special, incidental, punitive, exemplary, or consequential damages, including lost profits, arising out of or otherwise connected to the failure of a Thin-Set System, regardless of any strict liability or active or passive negligence of Schluter Systems, and regardless of legal theory, whether in contract, tort, extra-contractual or other. This Limited Warranty further excludes any loss or damage arising out of or otherwise connected to: acts of war, terrorism, fire, explosion, natural disaster, acts of God, any failure to comply with the Written Materials, inadequate subfloor/substrate, improper preparation or other failure of subfloor/substrate, faulty or negligent penetration of a Thin-Set System or subfloor/substrate, intentional acts of destruction, structural failure, misuse of or failure to maintain a Thin-Set System, normal wear and tear, scratches, dents, corrosion or discoloration (whether caused by excessive heat, chemical cleaning products, abrasive agents or otherwise), efflorescence and shading which are a natural occurrence with cementitious materials and are not considered a defective condition for the purposes of this Limited Warranty, variations of texture, color or shade from those on product samples, packaging materials or other marketing materials, or other causes unrelated to a Thin-Set System (e.g. excess point loading, overvoltage). This Limited Warranty excludes exterior, submerged and steam room applications and further excludes applications using glass tile, resin-backed tile, and/or moisture sensitive stone unless specifically approved in writing on a case by case basis by the Schluter Systems Technical Services Director. Schluter DITRA-HEAT™-E-HK heating cables and Schluter DITRAHEAT™-E thermostats are specifically excluded from coverage under this Limited Warranty. Any substitution of a non-Schluter Systems product for a Schluter Systems component in a Thin-Set System voids this Limited Warranty. ® ® DISCLAIMER: There are no warranties beyond this expressed warranty as stated herein. To the extent permitted by law, all other warranties, representations or conditions, expressed or implied, are hereby disclaimed and excluded, including but not limited to the implied warranties of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE (as limited to such purposes as described in the Written Materials) or arising from a course of dealing, usage of trade or otherwise by law.
