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.

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.

-Shower System

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-ST prefabricated foam tray. 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.

K-SHBF on page 10.

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-ST/-L/-LS/-SC/-SR and KERDI-BOARD-SC/-SB.

Limitations

Certain glass tiles may not be compatible with bonded waterproof membranes and/or may require special setting materials. Consult glass tile manufacturer and Schluter ® -Systems for more information.

Certain moisture sensitive stones, e.g., green marble, or resin-backed tiles may not be appropriate for use in wet areas such as showers or may require special setting materials. Consult stone supplier and

Schluter ® -Systems for more information.

Do not use sawn lumber curbs on concrete subfloors subject to moisture migration.

Solid Backing Materials

Gypsum wallboard – ASTM C1396/C1396M

Cementitious backer unit – ANSI A118.9 or ASTM C1325

Fiber-cement underlayment – ASTM C1288

Masonry

Requirements

Plywood, OSB, or concrete subfloor must be clean, even, and load bearing.

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-ST/-L/-LS or Portland cement mortar bed.

Curb – KERDI-BOARD-SC, KERDI-SHOWER-SC, KERDI-BOARD, concrete, masonry block, or sawn lumber sheathed with solid backing

(see above).

Bench – KERDI-BOARD-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.

KERDI waterproofing membrane shall be installed up to the height of the showerhead at minimum.

Any protrusions through the KERDI membrane (e.g., showerhead, mixing valve, etc.) must be treated with KERDI-SEAL-PS/-MV seals, KERDI-FIX or suitable sealant.

When using the stainless steel KERDI-DRAIN bonding flange, use

KERDI-FIX to bond KERDI to the drain.

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

When KERDI-SHOWER-ST/-L/-LS tray dimensions do not match the dimensions of the shower compartment, the tray may be cut or extended with dry pack mortar.

When KERDI 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 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.

Schluter ® -Systems profiles may be used to finish and protect outside corners and eliminate the use of sealant at inside corners; see page 36.

Schluter ® -SHOWERPROFILE-S/-R profiles eliminate the need for cutting wedges of tile by covering the exposed wall area where the floor slopes to KERDI-LINE.

Barrier-free 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 or 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 31.

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.



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 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. 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.

-KERDI-SHOWER-ST prefabricated shower tray

The substrate must be clean, even, and load bearing. Any leveling must be done prior to shower tray installation. If necessary, cut the tray to size prior to application; ideally, the tray is cut equally on all sides to ensure a consistent perimeter height. The base can also be extended beyond the tray using dry-pack mortar.

Plumbing Access: If there is access to the plumbing from below and the waste line can be connected after installing KERDI-DRAIN, the tray can be installed prior to the drain.

1 Apply unmodified thin-set mortar to the substrate using a 1/4" x 3/8" (6 mm x 10 mm) square- or U-notched trowel.

2 Place the KERDI-SHOWER-ST tray and solidly embed in the mortar. Check the underside of the tray to ensure full coverage and support are achieved.

3 Completely fill the step in the shower tray with thin-set mortar. Press KERDI-DRAIN firmly into the mortar to ensure full support of the bonding flange.

No Plumbing Access: When there is no access to the plumbing from below, KERDI-DRAIN is installed to the appropriate height and connected to the waste line prior to the installation of the shower tray.

1 Begin by dry-fitting the components.

Measure and cut a section of pipe to connect

KERDI-DRAIN to the odor trap using the detachable center section of the tray or foam spacers included with the drain as a spacer. Prepare the odor trap, pipe, and

KERDI-DRAIN with cleaner, primer and ABS or PVC cement per the solvent cement manufacturer’s instructions and connect.

-KERDI over solid backing

The thin-set mortar used for bonding KERDI to walls and ceilings must be appropriate for the substrate and must penetrate and engage the membrane fleece. For most substrates (e.g., gypsum board or CBU), an unmodified thin-set mortar is used. The mortar must be mixed to a fairly fluid consistency, but still able to hold a notch.

1

Clean any dust or other debris from the surface of the solid backing. Dampen particularly dry and porous substrates in order to help prevent premature drying or skinning of the thin-set mortar.

2

Place painter’s tape to protect the tub deck.

Apply unmodified thin-set mortar to the solid backing using a 1/4" x 3/16" (6 mm x 5 mm) V-notched trowel or the KERDI-

TROWEL. Completely fill the 1/4" (6 mm)wide gap between the solid backing and tub with KERDI-FIX or other suitable sealant.

Note: When the solid backing is installed above the tub flange, apply KERDI-FIX to the tub flange and spread using a small notched trowel.

3

Apply KERDI-BAND waterproofing strips or

5" (125 mm)-wide cut sections of KERDI waterproofing membrane. Solidly embed the membrane in the mortar and KERDI-FIX to ensure full coverage and remove air pockets.

4

Apply unmodified thin-set mortar to the solid backing and previously applied

KERDI-BAND. Embed the KERDI in the thin-set mortar and work the membrane onto the entire surface to ensure full coverage and remove air pockets.

5

Seams in the membrane are constructed by overlapping the edges of KERDI by

2" (50 mm) or by abutting adjacent sheets of

KERDI and installing KERDI-BAND, centered over the joint.

KERDI-SEAL-PS/-MV KERDI-FIX

6

Any protrusions through the KERDI membrane

(e.g., mixing valve, shower head, etc.) must be sealed with KERDI-SEAL-PS/-MV, KERDI-FIX, or other suitable sealant.

7 Seal connections to knee walls using

KERDI-KERECK-F preformed corners and unmodified thin-set mortar.

Note: See page 21 for KERDI-BOARD-SN shower niche installation instructions.

8 Once the entire membrane, including seams, corners, and knee walls have been completely bonded and, therefore, waterproofed, the assembly is ready to be tiled.

Grab bars or other heavy objects must be anchored in the structure or solid blocking behind KERDI-BOARD. Installation instructions for other applications of KERDI-BOARD (e.g. fully embedded or spot-bonded over solid backing) can be found in the 12.1 Schluter ® -KERDI-BOARD technical data sheet.

1

KERDI-BOARD can be mounted vertically or horizontally on framing with appropriate screws (e.g., coarse thread wood screw for wood studs and self-tapping for metal studs) and corresponding KERDI-BOARD-ZT washers. Minimum board thickness = 1/2"

(12.5 mm) for studs spaced at 16" (40.6 cm) o.c.; 3/4" (19 mm) for studs spaced at 24"

(61.0 cm) o.c. Screws must reach a depth of at least 3/4" (20 mm) in wood studs and at least 3/8" (10 mm) in metal studs.

2

Abut panels over the center of the studs or other solid backing. Screws may be placed between adjacent panels such that the washers fasten both panel edges. The maximum allowable on-center fastener spacing is 12" (30 cm) for walls and

6" (15 cm) for ceilings.

3

Place painter’s tape to protect the tub deck.

Apply unmodified thin-set mortar to the KERDI-BOARD using a 1/4" x 3/16"

(6 mm x 5 mm) V-notched trowel or the KERDI-TROWEL. Completely fill the

1/4" (6 mm)-wide gap between the

KERDI-BOARD and tub with KERDI-FIX or other suitable sealant.

Note: When KERDI-BOARD is installed above the tub flange, apply KERDI-FIX to the tub flange and spread using a small notched trowel.

4

Apply KERDI-BAND waterproofing strips.

Solidly embed the membrane in the mortar and KERDI-FIX to ensure full coverage and remove air pockets.

5 KERDI-BOARD joints, corners, and fastener penetrations are sealed with KERDI-BAND, ensuring a minimum 2" (50 mm) overlap.


6 Any protrusions through the panel

(e.g., mixing valve, shower head, etc.) must be sealed with KERDI-SEAL-PS/-MV,

KERDI-FIX, or other suitable sealant.

7 Seal connections to knee walls using

KERDI-KERECK-F preformed corners and unmodified thin-set mortar.

Note: See page 21 for KERDI-BOARD-SN shower niche installation instructions.

8 Once all seams, corners, and knee walls have been completely sealed, the assembly is waterproofed and ready to be tiled.

BARRIER-FREE 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.

Barrier-free 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 barrier-free 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.

Barrier-free 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 barrier-free 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 barrier-free showers. Secondary drainage may be required in the drying area for any overflow. Please see detail K-SHBF on page 10 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.

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.

DITRA

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.

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.

PROFILES

Details make the difference

Ceramic and stone tiles are durable, easy to maintain, and hygienic, representing the ideal surface coverings for showers and bathtub surrounds. 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.

THIN-SET FACTS

Discussion on thin-set mortars and Schluter

®

-KERDI installations

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.), 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.

Unmodified thin-set mortar must be used to construct all KERDI seams to ensure watertight performance of the system. Learn more below.

QUESTION: Can ceramic tile, including porcelain tile, be set on Schluter

®

-KERDI with unmodified thin-set mortar?

ANSWER: YES. In fact, 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: We DON’T recommend it. Here’s why:

Latex-modified mortars must air 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 would 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.

ADDITIONAL NOTES

• Over 25 years of field experience and testing by the Tile Council of North America (TCNA) support the efficacy of using unmodified thinset mortars in conjunction with KERDI in tiled showers.

• 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.

MOLD

The importance of mold control

The term “mold” is used to describe visible fungal growth. 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 39

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.

-KERDI-LINE

KERDI-LINE is a low profile linear floor drain specifically designed for bonded waterproofing assemblies. KERDI-LINE can be installed adjacent to walls or at intermediate locations in showers, wet rooms, and other applications that require waterproofing and drainage. The floor can be sloped on a single plane to KERDI-LINE, which enables the use of large-format tiles and creates interesting design opportunities.

KERDI-LINE consists of a formed stainless steel channel body and a grate assembly that can be seamlessly adjusted to the thickness of the ceramic tile or stone covering from 1/8" to 1" (3 mm to 25 mm). Grate assemblies are available in three designs: closed, perforated, or tileable covering support.

Note: There are multiple selections to be made for this product. Start by selecting the appropriate flange length then proceed to grate selection accordingly, keeping in mind there are two frame heights with two grate options (A or B), and a frameless option (D).

-KERDI-BOARD

KERDI-BOARD is a multifunctional tile substrate and building panel, which can also be used for creating bonded waterproofing assemblies with tile coverings. 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.

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-TB is a polypropylene membrane with a cut back stud structure and a thermal break anchoring fleece laminated to the underside. 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.

-Shower System 10-Year Limited Warranty

COVERAGE AND CONDITIONS: Subject to the conditions and limitations as stated hereinafter, Schluter ® -Systems* warrants that the

Schluter ® -Shower System (the “Products”)** will meet all composition and performance criteria for a period of ten (10) years from the date of purchase only when the Products are used and installed in accordance with the terms and conditions of the Schluter ® -Shower System Installation

Handbook and industry standard guidelines that are not in conflict with the Handbook in effect at the time of installation. Further, efflorescence is considered to be a natural occurrence with cementitious materials and is therefore not considered to be a defective condition and is not covered by this warranty. It is the responsibility of the owner/builder/installer to ensure the suitability of all building materials and all associated building materials for the owner’s intended use. It is recommended that the owner consult with an experienced and professional installer.

RESOLUTION: If the Products fail to meet this warranty, then 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 tile assembly or b) pay an amount not to exceed the original square foot cost of the installation of the tile assembly verified to be defective. Tile assembly is defined to include all Schluter ® -KERDI products, non-reusable tile surfaces, and the appropriate setting and grouting materials. Further, 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 covering materials used in the installation. In such events, substantially similar materials may be substituted.

DISCLAIMER: THERE ARE NO WARRANTIES BEYOND THIS EXPRESSED WARRANTY AS STATED ABOVE. ALL OTHER WARRANTIES,

REPRESENTATIONS OR CONDITIONS, EXPRESSED OR IMPLIED, ARE DISCLAIMED AND EXCLUDED, INCLUDING WARRANTIES,

REPRESENTATIONS OR CONDITIONS OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE ARISING BY STATUTE

OR OTHERWISE BY LAW OR FROM A COURSE OF DEALING OR USAGE OF TRADE. SCHLUTER ® -SYSTEMS EXCLUDES AND IN NO

EVENT SHALL HAVE ANY LIABILITY FOR LOST PROFITS OR ANY OTHER INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, EXEMPLARY, OR

CONSEQUENTIAL DAMAGES, ARISING OUT OF OR OTHERWISE CONNECTED TO FAILURE OF THE PRODUCTS, NOR MISUSE OF THE

PRODUCTS OR FAILURE TO PROPERLY MAINTAIN THE SHOWER OR BATHTUB SURROUND. REGARDLESS OF ANY STRICT LIABILITY,

ACTIVE OR PASSIVE NEGLIGENCE OF SCHLUTER ® -SYSTEMS, AND REGARDLESS OF THE LEGAL THEORY (CONTRACT OR TORT

OR EXTRA-CONTRACTUAL OR OTHER), NOR FROM ACTS OF WAR, TERRORISM, FAULTY AND NEGLIGENT PENETRATION OF THE

SYSTEM, FIRES, EXPLOSIONS, ACTS OF GOD, INTENTIONAL ACTS OF DESTRUCTION OR ANY LOSSES DUE TO STRUCTURAL FAILURE

THIS WARRANTY IS GIVEN IN LIEU OF ANY OTHER WARRANTY EXPRESSED OR IMPLIED. THE REMEDIES CONTAINED HEREIN ARE

THE ONLY REMEDIES AVAILABLE FOR BREACH OF THIS WARRANTY. THIS LIMITED WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS;

SOME STATES AND PROVINCES DO NOT ALLOW DISCLAIMERS OR OTHER RESTRICTIONS OF IMPLIED WARRANTIES, SO SOME OF

THE ABOVE DISCLAIMERS MAY NOT APPLY TO YOU.

TRANSFERABILITY: This Limited Warranty extends ONLY to the original end user (defined as original intended owner and user of the property/unit in which the installation is incorporated - herein referred to as “Owner”) and is not transferable or assignable, unless approved in writing by the Technical Director or an Officer of Schluter ® -Systems or otherwise prohibited by specific state or provincial law.

MODIFICATIONS TO WARRANTY: No changes or modification of any terms or conditions of this warranty are allowed unless authorized by written agreement and signed by the Technical Director or an Officer of Schluter ® -Systems.

EFFECTIVE DATE: This warranty shall supersede and replace any and all prior oral or written warranties, agreements, or other such representations made by or on behalf of Schluter ® -Systems relative to the Products or the application of the Products and shall apply to any installation occurring on or after January 1, 2013.

CLAIMS ON THIS LIMITED WARRANTY: To make a claim under this Limited Warranty, the Owner must provide Schluter ® -Systems with written notice within 30 days of any alleged defect in the Products covered by this Limited Warranty, together with date and proof of purchase of the Products, proof of the costs of the original installation and name and address of all installers, failing which this Limited Warranty shall be of no legal effect. Schluter ® -Systems reserves the right at its election and as a condition of this Limited Warranty to inspect the alleged failed and defective condition.
