Schlüter®-KERDI-SHOWER-T

Installation

  1. Position the drain body on the substrate according to the selected sloped tray and connect it to the existing drainage system, using a drain pipe cut to the appropriate size. If necessary, use the supplied adapter (DN 40 to DN 50) for connecting. Perform a water tightness test.
     
  2. Properly install the levelling layer (compressive strength >= 0.5 N/mm²) on the load bearing substrate. Make sure the entire drain body and the drainage pipe are fully encased for complete load transfer. Use the upper edge of the respective floor drain as a levelling guide and make sure it is flush with the upper edge of the levelling layer. If installing other floor drains from the Schlüter-KERDI-DRAIN system, determine the necessary screed assembly heights accordingly.

    Note: In case of impact sound insulation requirements, the load-transferring levelling layer must be installed over the sound insulation panel Schlüter-KERDILINE-SR and sealed with a suitable edge insulation strip along the perimeter. The maximum compressive strength CP4 (≤ 4 mm) must be taken into consideration to select a suitable insulation material.
     
  3. The sloped tray is then fully embedded on a sufficiently load-bearing levelling layer, using a dry-setting thin-bed tile adhesive. Carefully ensure that the joint of the sloped tray does not cover the channel the drainage pipe runs through.
     
  4. Insert the bonding flange into the precisely cut opening of the drain body so that the adhesive flange is flush with the surface of the sloped tray. For embedding, apply thin-bed tile adhesive below the adhesive flange beforehand.
     
  5. To adhere the KERDI collar – which is included in the scope of supply for KERDI-DRAIN – use a 3 x 3 mm or 4 x 4 mm notched trowel to apply KERDI-COLL-L to the bonding flange and the waterproofing collar of the sloped tray to fully embed the KERDI collar. Firmly push the collar in place with the smooth side of the notched trowel or by drawing a smoothing trowel over the KERDI collar at an angle under pressure. Make sure there are no air bubbles. The curing time of the adhesive must be observed.
     
  6. Fully embed the waterproofing membrane KERDI 200 for waterproofing the wall areas. Adhere the sealing band KERDI-KEBA and pre-fabricated Schlüter-KERECK corner pieces to the abutting membrane joints in the installation area as well as along the wall/ floor transitions with KERDI-COLL-L. Use the matching KERDI pipe collars for waterproofing pipe penetrations. Further instructions can be found in the corresponding product data sheets, 8.1 Schlüter-KERDI and 8.4 Schlüter-KERDI-COLL-L.

    Note: If the wall areas are covered with Schlüter-KERDI-BOARD, the same material can be used for waterproofing the walls (see product data sheet 12.1 Schlüter-KERDI-BOARD). Adhere KERDI-KEBA and KERDI-KERECK with KERDI-COLL-L to abutting joints and corner areas for waterproofing.
     
  7. Tiles can be installed in the thin-bed method as soon the bonded waterproofing has been completed as described above. No curing time is required.
     
  8. To install the tiles, apply the dry setting thin-bed tile adhesive directly on the KERDI collar and then fully embed the tiles in the adhesive. The floor area can withstand normal foot traffic, regardless of the tile dimensions. An additional load distribution layer or larger tile formats should be installed if higher traffic loads, e.g. from wheelchair use, are expected.

    Note: System-certified tile adhesives must be used in areas that require assemblies according to abP (certificate of technical approval) or CE-compliance. Please contact us at the address listed in this datasheet for further information about such products.
    As part of installing the floor tiles, insert the housing of the drain grate and the integrated odour trap into the bonding flange and align it flush with the surface in accordance with the tile thickness. Place tile adhesive underneath the grate frame.
     
  9. Other coverings such as coatings, vinyl and similar materials can be installed in principle, but are not described in further detail here and require additional 508 304 646 mm 965 mm Schlüter®-KERDI-SHOWER-T Schlüter®-KERDI-SHOWER on levelling screed Sample installation of Schlüter®-KERDI-SHOWER-TT L B 254 mm L B clarification.

The trays already feature the necessary slope for the drainage points. They are precisely customised to accommodate the KERDI-DRAIN bonding flange with adhesive flange.

Depending on the construction situation, the sloped tray can be installed on the corresponding load-bearing substrates (e.g. wooden floors, vertical drain, mortar substrate etc.).

The KERDI collar is pre-adhered to the sloped trays. For easier handling, the sloped trays are shipped in a folded format.

The sloped trays KERDI-SHOWER-KST 1525 and -KST 1830 comprise 2 parts, which can be connected to form a flush dovetail design. The connecting joint is sealed with KERDI-KEBA and KERDI-COLL-L.
