  1. For the installation of Schlüter®-KERDI-LINE-H with horizontal drain and odour trap, precisely adjust the height of the levelling board in such a way that the underside of the levelling board is flush with the underside of the channel support. It is recommended to first install the channel support including the channel body in the exact position. If the substrate is level and has the required height, you can use thin bed adhesive for attachment. To offset uneven sections or for height adjustment, the levelling board can also be installed and aligned over several, sufficiently spaced spots of mortar or over a full layer of levelling screed.
  2. If you are only installing the sloped tray, for example with the vertical line drainage Schlüter®-KERDI-LINE-V or for other construction related reasons, precisely adhere the sloped tray on a suitable substrate at the appropriate height. Note: If the building project requires impact sound insulation, install a suitable sound insulation under the levelling board or the sloped tray and attach an edge insulation strip along the perimeter.
  3. If any lateral pipes next to Schlüter®-KERDI-LINE with horizontal drain need to be covered, use the supplied prefabricated parts and attach them with thin bed adhesive.
  4. Using a utility knife, cut the sloped tray at the corresponding markings to match the selected dimension of Schlüter®-KERDI-LINE. Now adhere the sloped tray with thin bed adhesive in such a way that it is flush with the channel support of Schlüter®-KERDI-LINE. Slide the small indentation of the adjoining surface of the sloped tray laterally below the flange.
  5. To establish a waterproof connection between the sloped tray and the channel body, use the sealing adhesive Schlüter®-KERDI-COLL-L to adhere the pre fabricated Schlüter®-KERDI collar onto the adjoining waterproofing assembly.
  6. As soon as the bonded waterproofing assembly has been completed (see also product data sheets 8.1 Schlüter®-KERDI and 8.4 Schlüter®-KERDI-COLL-L), you can begin to install the tiles with the thin bed adhesive. No waiting is required. 
  7. For the installation of the tiles, apply drysetting thin bed adhesive directly on the Schlüter®-KERDI membrane and fully embed the tiles in the adhesive. Note: Areas in which the Schlüter®-KERDI waterproofing assembly must meet the requirements of the general certificate of national technical approval (abP) or CE conformity must be created with thin bed adhesive that are approved for use with Schlüter®-KERDI. Please contact us for a list of approved tile adhesives.
  8. 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, depending on requirements. We will be pleased to provide you with further recommendations upon request.
  9. The sloped tray Schlüter®-KERDI-SHOWER-BSL-/-BSLS can also be used as a sloped insulation layer. For this purpose, adjust it to the height of the adjoining insulation and cover it with screed. We recommend the installation of a Schlüter®-BEKOTEC screed, which can be built as an unheated floor or as a heated assembly with Schlüter®-BEOTEC-THERM. If applicable, the shower area may need to be separated from the adjoining areas with an expansion joint.
