Schlüter-RONDEC-AC  Finishing profile made of colour-coated aluminium in various colour options

Schlüter-RONDEC-AC is a finishing profile made of colour-coated aluminium for external wall corners of tile coverings. The outer surface of the profile forms a symmetrically rounded external corner in tile coverings. The integrated joint spacer forms a defined joint cavity with the tile. RONDEC-AC profiles are available in different colours to coordinate with tile and grout, fixtures and fittings or to create interesting accents in decorative design. In addition to their decorative effect, our aluminium profiles also offer reliable edge protection against mechanical impact for the tiles in the edge area.

RONDEC-AC is also suitable for creating transitions, corners or skirtings with other covering materials such as carpet, parquet, natural stone or epoxy resin finishes.

Matching corner pieces and connectors are available for RONDEC-AC profiles to create simple and elegant connections to internal and external corners.

General product information

How to install this product

  1. Select Schlüter-RONDEC-AC according to tile thickness.
  2. Apply tile adhesive to the area where the tile covering will end, using a notched trowel. If RONDEC-AC is used at external wall corners, finish tiling one wall first; then apply tile adhesive to the corner area of the second wall.
  3. Press the perforated anchoring leg of RONDEC-AC firmly into the adhesive and align it.
  4. Trowel additional adhesive over the perforated anchoring leg to ensure full coverage and fill the rounded cavity with tile adhesive.
  5. Solidly embed adjacent tiles and adjust them flush with the profile’s upper edge. Full coverage must be obtained between the tile and the profile’s anchoring leg.
  6. The tile is set to the lateral joint spacer, which creates an evenly spaced joint of 1.5 mm. Completely fill the space between the tile and the profile with grout.
  7. Use suitable materials and tools for the sensitive surfaces to avoid scratches or other damage. Setting materials must be removed immediately, especially on aluminium.
  8. Matching preformed inside and outside corner pieces are available.
