Schlüter®-KERDI-DRAIN-SP-E | Installation | Schlüter-Systems



  1. Drill an opening of at least 48 mm in diameter into the upright parapet or, in case of new construction, leave an opening of that size.
  2. Slide the Schlüter®-KERDI-DRAIN-SP spout into the opening in such a way that the flange is flush with the substrate and the parapet. If necessary, the installation adhesive Schlüter®-KERDI-FIX may be used for attachment.
  3. Adhere a Schlüter®-KERDI collar to create a waterproof transition to the screed. In a next step, install the area drainage mat Schlüter®-KERDI with a sufficient overlap over the collar. If Schlüter®-DITRA 25 is used as an area drainage product, install the mat to fully cover the flange. Now install the Schlüter®-KERDI collar by embedding it on the Schlüter®-DITRA 25 mat with a full overlap. The Schlüter®-KERDI collar is best adhered with the sealing adhesive Schlüter®-KERDI-COLL or the installation adhesive Schlüter®-KERDI-FIX. If other waterproofing systems are used, complete them according to the respective manufacturer’s instructions. The applicable product data sheets 6.1 Schlüter®-DITRA 25 and 8.1 Schlüter®- KERDI must be observed.
