Schlüter®-TREP-G /-GL /-GK /-GLK


  1. Select Schlüter-TREP-G / -GL according to the tile thickness.
  2. Align the covering material at the riser.
  3. Apply a suitable tile adhesive to the edge area above the stepr riser.
  4. Fill the hollow spaces on the underside of the profile with suitable tile adhesive. Note for steps 3 and 4: In case of thicker adhesive layers in the edge area, it may be necessary to add sand to the dry setting thin bed adhesive in accordance with manufacturer instructions or to use a medium bed mortar.
  5. Embed Schlüter-TREP-G / -GL fully into the adhesive bed and align the profile in such a way that the front edge of the profile covers the riser tiles.
  6. Trowel additional setting material over the trapezoid perforated anchoring leg and the tread of the stair step to ensure full coverage.
  7. Solidly embed the horizontal tiles and align them flush with the top edge of the profile. The tiles must be fully embedded in the area of the profile.
  8. Leave a joint of approximately 2 mm between the tile and the profile.
  9. Completely fill the space between the tile and the profile with grout. Prior to the application of grout, cover the non slip tread with a suitable adhesive tape.
  10. When integrating Schlüter-TREP-G / -GL into screed layers, fully embed the profile in the mortar and cover the trapezoid perforated anchoring leg with at least 15 mm of screed mortar.

Installation of Schlüter-TREP-GK / -GLK

  1. Clean the stair nosings and repair damaged areas if applicable.
  2. Clean or degrease the underside of Schlüter-TREP-GK.
  3. Adhere the profile by fully embedding it into a suitable adhesive (e.g. epoxy resin or Schlüter-KERDI-FIX, depending on the substrate). Note: The upper profile edge is approx. 1.5 mm higher than the stair covering.

Changing the non slip tread
When changing the non slip tread, ensure the surrounding temperature is at least 10 °C.

  1. Remove all residue of the previous selfadhesive tape.
  2. Prior to attaching the new tape, clean the surface of the profile with a solvent.
  3. Peel back approx. 5 cm of the protective liner and position the self-adhesive tape on the surface of the profile. Avoid touching the adhesive with your fingers.
  4. Peel the protective liner back further and gradually install the full length of the tape.
  5. Use a rubber roller to firmly press the self-adhesive tape into place. Always begin from the centre and roll toward the edges.
