Schluter®-DILEX-HKU features a single trapezoid-perforated anchoring leg that turns inward, which is secured in the mortar bond coat, and a stainless steel cove section that forms the visible surface. The profile’s 3/8" (10 mm) or 1-13/32" (36 mm) radius prevents the accumulation of dirt and makes cleaning simple. The profile separates tile fields that meet at inside corners where limited movement is expected. DILEX-HKU may be used with floor coverings other than ceramic and stone tile, provided that the coverings are fastened or adhered (i.e., no floating floors). DILEX-HKU prevents surface water penetration and meets the maintenance and hygienic requirements of commercial kitchens, bathrooms, food-processing plants, or any tiled environment where a sanitary cove is desired. Accessories available for the DILEX-HKU include inside and outside corners, connectors, and end caps.

DILEX-HKU requires no special maintenance or care and are resistant to mold and fungi. Clean profile using common household cleaning agents. Stainless steel surfaces exposed to the environment or aggressive substances should be cleaned periodically using a mild household cleaner. Regular cleaning maintains the neat appearance of stainless steel and reduces the risk of corrosion. All cleaning agents must be free of hydrochloric acid, hydrofluoric acid, and chlorides. Stainless steel surfaces develop a sheen when treated with a chrome-polishing agent.

1. Select profile according to tile thickness and format.

Note: DILEX-HKU with 3/8" (10 mm) radius may be used with 1/4" (6 mm) and thicker tiles. DILEX-HKU with 1-13/32" (36 mm) radius may be used with 5/16" (8 mm) and thicker tiles.

2. Using a notched trowel, apply thin-set mortar over the area where the trapezoid-perforated anchoring legs will be placed.

Note: When using thicker tiles with DILEX-HKU, apply additional mortar behind the anchoring leg.

3. Press the perforated anchoring leg(s) of the profile into the mortar.

Note:  Internal connectors for DILEX-HKU are inserted prior to profile installation. Leave approximately a ½” (12.5 mm) space between the adjacent profiles. This space will be covered by the surface applied connectors. The DILEX-HKU  accessories are applied using permanently elastic, waterproof adhesive (e.g. KERDI-FIX or silicone).

4. Trowel additional thin-set mortar where the tiles are to be installed.

5. Solidly embed the tiles, ensuring full coverage and support of the tile edges, and align flush with the top of the profile, leaving a joint of approximately 1/16" – 1/8" (1.5 - 3 mm) between the tile and the profile.

6. Fill the joints completely with grout or setting material.
