Schlüter®-KERDI/KERDI-KEBA

Installation

  1. The substrate must be free of bond inhibiting components, be load bearing and even. Any unevenness in the substrate must be levelled prior to the application of Schlüter®-KERDI.
  2. The type of bonding adhesive used to apply Schlüter-KERDI depends on the type of substrate. The adhesive must bond to the substrate and mechanically anchor the fleece on the underside of the Schlüter-KERDI matting. Verify the compatibility of all materials prior to installation. If using covering materials with a lateral length ≥ 30 cm, we recommend a waterbinding tile adhesive for rapid curing and drying.
    Note:
    System tested adhesive must be used in areas that require special approval of the authorities. Please contact us at the address shown in this data sheet for more details.
  3. Apply the bonding adhesive to the substrate using a 3 x 3 mm or 4 x 4 mm notched trowel.
  4. Individual courses of Schlüter®-KERDI are cut to size. Solidly embed the anchoring fleece on the underside in the adhesive so that its entire surface is bonded. Work the material into the adhesive with the smooth side of a notched trowel or a float, exerting pressure on the Schlüter®-KERDI matting in diagonal strokes. Avoid the formation of air bubbles and observe the open time of the bonding adhesive.
  5. Overlap the joints of the KERDI membranes by at least 5 cm or abut the joints and fully cover the joint with Schlüter®-KERDI-KEBA, using the sealing adhesive Schlüter®-KERDI-COLL-L.
  6. Use the pre-fabricated KERDI corners for internal and external corners. Schlüter®-KERDI-KEBA must be adhered to corner joints in the same manner. Use Schlüter®-KERDI-KM (pipe collar) for pipe penetrations. Functional connections to fixed structural components can be created as well. Depending on the situation of the construction site, Schlüter®-KERDI, -KERDI-KEBA or -KERDI-FLEX can be attached to the adjoining structural element with Schlüter®-KERDI-FIX to create a waterproof connection (see Product Data Sheet 8.3, Schlüter®-KERDI-FIX).
  7. Clamp or tightly adhere a 50 cm x 50 cm piece of Schlüter®-KERDI onto the flange of the floor drains constructed in the thin-bed method as a connector collar. Then bring the Schlüter®-KERDI mat within 10 cm of the floor drain and adhere it to the connector collar without leaving air pockets. Schlüter®-KERDI-DRAIN is a floor drain specifically designed to allow connections to a bonded waterproofing membrane. This allows the simple and fast connection of Schlüter®-KERDI to the floor drain, using the Schlüter®-KERDI collar.

    Note regarding floor drains:
    Schlüter®-KERDI-DRAIN and Schlüter®-KERDI-LINE are components that were specifically developed for connection to bonded waterproofing assemblies. Schlüter®-KERDI can be quickly and reliably abutted in these cases with the use of Schlüter®-KERDI collars.
  8. Cut Schlüter®-KERDI above structural and seismic expansion joints, then cover the joint with Schlüter®-KERDI-FLEX. Schlüter®-KERDI-FLEX can also be used for flexible finishing edges. Alternatively, Schlüter®-KERDI-KEBA may be used, provided a loose fold is left above the joint.
  9. The covering can be installed as soon as the entire waterproofing assembly is tightly sealed at all overlaps, corners and joints. No waiting is required. For the installation of tile, apply dry setting thin-bed adhesive directly over Schlüter®-KERDI and fully embed the tiles in the adhesive.
    Suitable reactive resin adhesives and grout adhesive must be used for coverings that are likely to be exposed to chemicals. Exclusively use system-approved thin bed adhesives for areas that require CE conformity or compliance with the general certificate of national technical approval (abP). Please contact us at the address shown in this data sheet for further information about suitable adhesives and the corresponding test certificates.
