1. Schlüter-RONDEC-DB can be used with tiles in thicknesses from 6 to 12 mm.
2. Apply tile adhesive to the area where the tile covering will end, using a notched trowel. If RONDEC-DB 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-DB firmly into the adhesive and align it.
4. Trowel additional tile adhesive over the perforated anchoring leg to ensure full coverage.
5. Firmly press the adjoining tiles into place and align them. Full coverage must be obtained between the tile and the profile’s anchoring leg.
6. 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.

Schlüter-RONDEC-DB is available in aluminium (-A), anodised aluminium (-AE), and brass anodised aluminium (-AM).

Material properties and areas of application

Schlüter-RONDEC-DB-A is made of aluminium and must be tested to verify its suitability if chemical exposure is expected. Aluminium is sensitive to alkaline media. Cementitious materials, in conjunction with moisture, become alkaline, which may result in corrosion depending on the concentration and length of exposure (aluminium hydroxide formation). Therefore, it is important to remove adhesive or grout residue from visible surfaces. Solidly embed the profile in the setting material to prevent alkaline water from accumulating in small cavities.

Schlüter-RONDEC-DB-AE and -AM are made of anodised aluminium. The anodised layer 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, which may result in corrosion depending on the concentration and length of exposure (aluminium hydroxide formation). For this reason, remove adhesive or grouting material immediately from all visible areas and do not cover freshly installed coverings with foil. In addition, ensure that the profile is solidly embedded in the setting material to prevent water from accumulating in small cavities.
