Application and Function

Schluter-RONDEC-STEP is a finishing and edging profile for ceramic tile and dimension stone installations on countertops and stairs.

The profile features a trapezoid-perforated anchoring leg, which is secured in the mortar bond coat beneath the tile. The top of the profile features a symmetrically rounded edge with 1/4" (6 mm) radius, which matches the Schluter-RONDEC profile, while the vertical leg of the profile hides the exposed edge of the sub-assembly.

In addition, the profile effectively protects tiles in the edge area from mechanical and impact stresses. The integrated joint spacer establishes a defined joint cavity between the tile and the profile. Schluter-RONDEC-STEP is suitable for residential applications, e.g., stairs not exposed to heavy traffic, and counter tops.

Schluter-RONDEC-STEP is available in two different vertical leg lengths, 1-1/2" (39 mm) and 2-1/4" (57 mm), to cover the edge of the sub-assembly. The profile is available in anodized aluminum with various finishes to allow for decorative design and interesting accents. Matching corners for the RONDEC-STEP are available.

  1. Select Schluter-RONDEC-STEP according to tile thickness.
  2. Using a notched trowel, apply thin-set mortar to the area where profile is to be placed.
  3. Press the perforated anchoring leg of profile into the mortar and align.
  4. Trowel additional thin-set mortar over the perforated anchoring leg to ensure full coverage and support of the tile edges.
  5. Solidly embed the tiles so that the tiled surface is flush with the top of the profile; the profile should not be higher than the tiled surface, but rather up to approx. 1/32" (1 mm) lower.
  6. Set the tile to the integrated joint spacer, which ensures a uniform joint of 1/16" - 1/8" (1.5 - 3 mm).
  7. Fill the joint completely with grout or setting material.
  8. Work with materials and tools that will not scratch or damage sensitive surfaces. Setting materials and grouts must be removed immediately, especially from anodized aluminum surfaces.


Schluter-RONDEC-STEP is available in anodized aluminum.

In special cases, the suitability of a proposed type of material must be verified based on the anticipated chemical, mechanical, and/or other stresses.

Schluter-RONDEC-STEP, in anodized aluminum, features an anodized layer that retains a uniform appearance during normal use. The surface, however, is susceptible to scratching and wear and may be damaged by grout or setting material. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminum is sensitive to alkaline substances, exposure to the alkali (depending on concentration and duration of exposure) may result in corrosion (aluminum oxide formation). Therefore, it is important to remove mortar or grout residue immediately from visible surfaces. In addition, ensure that the profile is solidly embedded in the setting material and that all cavities are filled to prevent the collection of alkaline water.

Anodized aluminum is resistant to mold and bacteria, making the profile suitable for use around food.


Schluter-RONDEC-STEP requires no special maintenance or care and is resistant to mold and fungi. Clean the profile using common household cleaning agents.

Do not use abrasive cleaning agents.
