  1. The levelling board is installed in dry setting thin bed adhesive on a level substrate. To offset uneven sections or for height adjustment, the levelling board can also be installed and aligned over several sufficiently spaced dabs of adhesive or a layer of levelling screed.
    If the building project is subject to sound insulation requirements, install the levelling board over a sound insulation panel and attach an edge insulation strip along the perimeter. Observe the maximum compressibility CP4 (< 4mm) when selecting a suitable insulation material.
  2. Cut out the necessary openings in the levelling board for the pipes in the appropriate places. 
  3. Insert the drain body into the corresponding opening of the levelling board and connect it to the wastewater system with a drain pipe, using the supplied adapter piece (DN 40 to BS 40 mm). Perform a leakage test.
  4. Now adhere the sloped board to the prepared levelling board with a dry setting thin bed adhesive. Avoid placing the abutting joint of the sloped tray directly over the drain pipe.
  5. Fit the bonding flange into the drain body through the opening so that the flange is flush with the surface of the sloped board. Apply thin bed adhesive under the flange for complete attachment and bedding.
  6. To integrate the Schlüter®-KERDI collar into the bonded waterproofing assembly, apply the sealing Schlüter®-KERDI-COLL-L to the adhesive flange of the bonding flange insert and use a notched trowel to spread dry setting tile adhesive on the remaining area of the sloped tray to completely embed the Schlüter®-KERDI collar. Press the Schlüter®-KERDI collar in place with the smooth side of the notched trowel or a smoothing trowel by applying oblique pressure. Be careful to avoid the formation of bubbles and observe the curing times of all materials.
  7. To waterproof the wall areas, install the waterproofing membrane Schlüter®-KERDI. Where the joints of the membranes abut, in the corner areas, and along the floor to wall transition should be sealed with Schlüter®-KERDI-KEBA and Schlüter®-KERDI-COLL-L. Waterproof all pipe sleeves with the pipe collar Schlüter®-KERDI-KM. The corresponding product data sheets 8.1 Schlüter®-KERDI and 8.4 Schlüter®- KERDI-COLL-L must be observed.
    If the wall areas are made of Schlüter®-KERDI-BOARD, the material can also be used for waterproofing the walls (see product data sheet 12.1 Schlüter®-KERDI-BOARD). Abutting joints and corners also have to be sealed with Schlüter®-KERDI-KEBA sealing band, using the adhesive Schlüter®-KERDI-COLL-L.
  8. As soon as the bonded waterproofing assembly has been completed as described above, you can begin to install the tiles in the thin bed method. No waiting is required.
  9. For the installation of tile, apply drysetting thin bed adhesive directly over Schlüter®-KERDI and fully embed the tiles in the adhesive. Regardless of the tile format, the floor area can withstand normal foot traffic and is able to bear the weight of wheelchairs. If higher traffic loads are expected, an additional load distribution layer or larger tile formats may be required.
    Use system approved thin bed adhesives for areas that require waterproofing in accordance with general certificate of national technical approval or CE conformity. Please contact us at the address shown in this data sheet for more details. As part of the installation of the floor tiles, press the drain grate frame into the thin bed adhesive until flush with the tile covering. Tile adhesive can be applied below the grate frame for additional support, if required.
  10. Other coverings, such as coatings, synthetic coverings etc. may be used in principle, but are not explained in greater detail here. Their use must be clarified in advance. We will be pleased to provide you with further recommendations upon request.
