New Universal Substrate from Schlüter-Systems

A new universal substrate for tiles has been developed by Schlüter-Systems, market leader in essential tiling solutions.

This innovative and unique addition to Schlüter’s portfolio of full systems solutions serves as a substrate and bonded waterproofing solution.

Schlüter®-KERDI-BOARD gives an absolutely level substrate with straight and precisely angled internal and external corners, providing an instant base for a perfect tile covering.

Many substrates, both in new buildings and renovation projects, are unsuitable for tile installation, especially in areas of high moisture. These often need comprehensive additional work and waterproofing measures.

However, the new Schlüter®-KERDI-BOARD creates a perfect substrate for tile installation in both new build and renovation projects. It is ideal for:

• Masonry of all kinds, including green masonry
• Concrete
• Existing substrates such as plaster, tiles and painted surfaces
• Mixed substrates
• Wood or metal stud frames
• Partition walls
• Panelling bathtub surrounds
• Vanities and shelving
• Kitchen work surfaces
• Concealing pipes

A special version, Schlüter®-KERDI-BOARD-V, comes with vertical grooves, designed for creating rounded and curved designs in applications such as self supporting partition walls, tub surrounds, panelling of support structures and columns and panelling of pipes and installation ducts.

Schlüter®-KERDI-BOARD is quick and easy to install using mortar or screws, anchors and profiles from the Schlüter®-KERDI-BOARD attachment hardware package, depending on the application. The panel comes in seven thicknesses: 5 mm, 9 mm, 12.5 mm, 19 mm, 28 mm, 38 mm and 50 mm, meaning that there should be a panel suitable for any particular application.

Because of its extremely lightweight construction – it contains no cement or fibreglass – it is easy to transport, handle and cut. Its top and bottom surfaces comprise a fleece webbing with a reinforcement layer immediately underneath and a thickness of extruded hard foam in the centre.

Accessories include the angle component Schlüter®-KERDI-BOARD-E and the U shaped Schlüter®-KERDI-BOARD-U which are particularly useful for creating boxes to conceal pipes and ducts.

Amongst Schlüter®-KERDI-BOARD’s many unique benefits:

• Flat, strong and lightweight, but does not contain cement or fibreglass
• Grooved panels for curved features
• U shaped panels for piping, which can be stored and transported flat
• Quick and easy to install
• Lightweight, easy to handle and transport
• Dust free and easy to cut with a utility knife
• Printed gridlines for precise cutting
• Waterproof and temperature resistant
• Thermally insulating
• Fleece webbing for easy anchoring in thin-bed mortar

Typical Applications

To be suitable for the installation of tiles in the thin-bed method, the substrate must be completely level and made of an appropriate moisture resistant material. However, walls are frequently covered with a gypsum plaster coating as part of the construction process. Plaster is not suitable for tiling onto, especially in areas of high moisture. Additionally, these surfaces are typically not even enough. Other materials such as drywall panels or wood composite are equally unsatisfactory in these areas. Schlüter®-KERDI-BOARD provides the ideal substrate for these installations.

Sanitary installations frequently require partition walls for separate shower or toilet facilities or public changing rooms. Making such walls of bricks or covered stud frames is time consuming and surfaces often need further preparation before they are ready for tiling. Appropriate panel thicknesses of Schlüter®-KERDI-BOARD can be used to quickly and simply create stable and self supporting partition walls that are immediately ready for tiling.

In bathroom construction, contractors are frequently expected to prepare the surroundings of bathtubs and shower trays with a suitable substrate for tiling. Schlüter®-KERDI-BOARD can be used for bathtub coverings that are ready for tiling straight away. The grooved version, Schlüter®-KERDI-BOARD-V, makes it easy to provide effective curved panelling, especially useful for mosaic tiles.

Because it is waterproof and easy to cut with a utility knife, Schlüter®-KERDI-BOARD is the ideal substrate for constructing individually designed vanity units, shelving and kitchen worktops for a ceramic tile and natural stone surface. The visible edges can be finished in a number of ways using Schlüter®-RONDEC, Schlüter®-QUADEC or Schlüter®-RONDEC-STEP profiles.

The innovative prefabricated angle and U shaped components of Schlüter®-KERDI-BOARD make it especially easy to conceal pipes and ducts.

The grooved Schlüter®-KERDI-BOARD-V is designed for creating rounded and curved structures and surfaces. The panel forms quick and easy to assemble substrates for the creative design of support structures and columns, tub surrounds, panelling for pipes and ducts, wall coverings and self supporting partition walls such as multiple shower cubicles.
