Schlüter-RONDEC-A  Rounded finishing profile made of anodised aluminium

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

RONDEC-A is ideally suited for creating borders in combination with Schlüter-DESIGNLINE. These profiles are 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-A profiles to create simple and elegant connections to internal and external corners.

General product information

How to install this product

  1. Select Schlüter-RONDEC-A according to tile thickness.
  2. Apply tile adhesive to the area where the tile covering will end, using a notched trowel. If RONDEC-A 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-A 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.

Material properties and areas of application

Schlüter-RONDEC is available in a wide variety of materials and finishes.

In applications exposed to chemical or mechanical stresses, the profile’s suitability must be verified. The information provided below is intended as a general guideline.

Schlüter-RONDEC-A (anodised aluminium): The aluminium features an anodised finish that retains a uniform appearance during normal use. Surface areas must be protected against abrasion or scratching. Aluminium is sensitive to alkaline media. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminium is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and duration of exposure) may result in corrosion (aluminium hydroxide formation). Remove adhesive or grout immediately from visible areas and don't cover freshly installed assemblies with a protective foil. In addition, ensure that the profile is solidly embedded in the setting material to prevent water from accumulating in small cavities.

Note: Due to different manufacturing processes, slight colour discrepancies between the profiles and the corners may occur.

How to look after this product

Schlüter-RONDEC-A requires no special maintenance or care. Do not use abrasive cleaning agents on the sensitive surfaces. Use conventional polishes to remove the oxidation layer on aluminium; however, oxidation will reoccur. Applying lacquer can repair anodised layers.

All cleaning agents must be free of hydrochloric and hydrofluoric acid.
