Schluter-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. With the available panel thicknesses of 3/16″, 3/8″, 1/2″, 3/4″, 1″, 1-1/2″, and 2″, KERDI-BOARD allows the installer to prepare and create a broad range of substrates and building elements for the installation of ceramic and natural stone tile that are flat, level, plumb, square, and dimensionally stable. With suitable preparation of the abutting seams and joint areas, the panel may be used for bonded waterproofing assemblies.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.
The Universal Substrate for Tiles
Whether you work with mosaics or largeformat tiles, an absolutely flat substrate with straight and precisely aligned inside and outside corners is essential for creating a perfect tile covering. Tile setters can now achieve flat, level, plumb, and square substrates with Schluter-KERDI-BOARD. Schluter-KERDI-BOARD gives tile setters more control over their projects by providing them with the means to simply and easily create ideal substrates for tile. Unsuitable substrates can be remedied and new substrates can be created while keeping the technical and aesthetic requirements of the tile covering in mind. For this purpose, Schluter-KERDI-BOARD offers the following properties: • Even, impact-resistant, and rigid • Waterproof, temperature-resistant, and dimensionally stable • Vapor-retardant • Thermally insulating • Fleece webbing for easy anchoring in thin-set mortar • Quick and easy to install • Lightweight, easy to handle and transport • Contains no cement or fiberglass • Dust-free and easy to cut (with a utility knife) • Printed gridlines for precise cutting • Suitable for use on any kind of structure • Suitable for bathtub platforms, freestanding partition walls, vanities, storage shelves, countertops, and various other elements
Ideal Tile Substrate over existing/mixed substrates
Schluter-KERDI-BOARD is quick and easy to install as a substrate for tile coverings over wood or metal framing, using the screws and washers included in our hardware assortment. Panel joints are to be located on the studs or other solid backing. KERDI-BOARD can be installed vertically as well as horizontally.Tiles can be installed with thin-set mortar immediately after the proper attachment of KERDI-BOARD; no additional prep is required. Sanitary installations frequently require partition walls to create separate shower or toilet stalls or to divide rooms. The construction of such walls using masonry blocks or stud framing with sheathing is time-consuming and often requires further preparation before tiling can begin.Suitable panel thicknesses of Schluter-KERDI-BOARD can be used to quickly and simply create stable and selfsupporting partition walls for tiling. If required, the partition walls can be further attached or stabilized with the angled and U-shaped profiles, which form part of the complete system. The abutting seams and joints must be filled with thin-set mortar. Stainless steel profiles can be used to cover the visible areas.
Shower and Bathtub Surrounds
Tiled showers and bathtub surrounds require proper moisture management to ensure successful long-term performance. While cement backerboards are moistureresistant, they are not waterproof. Thus, additional measures must be taken to protect wall cavities from water and vapor penetration.In addition to being lightweight and easy to cut with a utility knife, Schluter-KERDIBOARD is inherently waterproof and vapor retardant. When used in conjunction with the Schluter-Shower System, KERDIBOARD provides an integrated tile backing and moisture management system for tiled showers and bathtub surrounds.
Bathtub platforms are excellent opportunities for tile coverings. However, tile setters are often faced with substandard framing, particularly on new construction projects. Many of the materials used to build the platforms are moisture-sensitive and require additional preparation prior to setting tile. Schluter-KERDI-BOARD can be used to quickly and simply create flat, level, plumb, square, and waterproof tub platforms. The grooved versions of the panel and the easy cutting properties of Schluter-KERDI-BOARD also allow for effective use in creating curved surfaces.
Vanities and Shelving
Schluter-KERDI-BOARD is the ideal substrate for constructing vanities and shelving with tile coverings. Using KERDIBOARD as a building panel makes it possible to quickly and easily build the vanity structure with the technical and aesthetic requirements of the tile covering in mind. The visible edges can be finished in a number of ways, including: • Brushed stainless steel U-shaped profiles in combination with the Schluter-RONDEC or Schluter-QUADEC finishing profiles • Schluter-RONDEC-CT or Schluter-RONDEC-STEP edge profiles • Tile strips and two finishing profiles such as Schluter-RONDEC or Schluter-QUADEC
Tiled countertops are often constructed with plywood decks, which are dimensionally unstable and moisturesensitive. Additional work is required to prepare the surface for tile installation, which can be time-consuming. Schluter- KERDI-BOARD is particularly suitable for building countertops and other work surfaces with tile coverings. KERDI-BOARD is dimensionally stable and waterproof and can be adhered directly to base cabinets, thus eliminating the need for labor intensive preparation. Panels and openings are easily cut with a utility knife. The sink rail can be created in a number of ways, including: • Brushed stainless steel U-shaped profiles in combination with the Schluter-RONDEC or Schluter-QUADEC finishing profiles • Schluter-RONDEC-CT or Schluter-RONDEC-STEP edge profiles • Tile strips and two finishing profiles such as Schluter-RONDEC or Schluter-QUADEC
Pipe and Column Coverings
The innovative, prefabricated L-shaped and U-shaped panels of the Schluter-KERDI-BOARD system make it especially easy to conceal pipes and columns. The panels feature V-shaped grooves and are shipped in a space-saving flat design, which makes them easy to store. The flat panels are also quick to cut to the necessary dimensions. Thin-set mortar, Schluter-KERDI-FIX, or double-sided adhesive tape is applied to the V-grooves. Fold the panels prior to installation.
Curved Wall Areas, Columns, and Fixtures
The grooved version of the Schluter-KERDI-BOARD panel is designed for creating rounded and curved elements. The panel allows for quick and easy creation of: • Self-supporting partition walls (e.g., for multiple shower cubicles) • Tub surrounds • Coverings for support structures and columns • Coverings for pipes and duct work • Wall coverings If the grooved surface points toward the inside, it is recommended that the grooves be filled with thin-set mortar prior to installation. If a larger expanse of panels is required, several panels can be connected along the edges with thin-set mortar, Schluter-KERDI-FIX adhesive, or double-sided adhesive tape.
