Schluter®-BARA-RTK is a color-coated aluminum edging and finishing profile for the exposed edges of floor assemblies on balconies and terraces that have an existing sloped substrate. A T-shaped chamber in the vertical leg of BARA-RTK is provided for attaching the Schluter®-BARIN gutter system. BARIN is fastened to the balcony edging profile with screws. The screw slots in the gutter are elongated, making it possible to slope the gutter up to 1-3/16" (30 mm).

The trapezoid-perforated anchoring leg of RTK should be integrated with a bonded sheet-applied or trowel applied waterproofing membrane. Once the anchoring leg of BARA-RTK becomes integrated with a suitable waterproofing membrane, the tiles can be bonded directly to the waterproofing layer by observing the manufacturer’s specifications. SCHIENE or RONDEC can be applied to edge the tiles at the recessed transition to the drip lip. The tiles can also be laid with an overhang.

Note: When using BARA-RTK as an edging profile for floor assemblies that are to receive a waterproofing membrane with a mortar screed on top, a drainage layer, such as TROBA or TROBA-PLUS, must be incorporated into the surface assembly. Matching inside corners, outside corners, and connector pieces are available for BARA-RTK.

1. Using a notched trowel, apply thin-set mortar to the area where BARA -RTK is to be placed. Press the perforated anchoring leg of the profile into the thin-set mortar and align.

2. To integrate the DITRA or DITRA-XL uncoupling membranes, abut the DITRA or DITRA-XL to the edge of the anchoring leg. The remaining joint between the uncoupling membrane and the profile is covered with KERDI-BAND; the KERDI-BAND must overlap the DITRA or DITRA-XL by a minimum 2" (5 cm) and cover the anchoring leg of the BARA-RTK. Use KERDI-FIX to bond KERDI-BAND to the BARA- RTK between the trapezoid perforations and the leading edge of the profile. Use unmodified thin-set mortar to bond KERDI-BAND to DITRA or DITRA-XL and the remaining area of the BARA- RTK.

3. The tiles may now be installed using the thin-bed method. SCHIENE or RONDEC can be applied to edge the tiles at the recessed transition to the drip lip. Select the SCHIENE or RONDEC size according to tile thickness; larger size will be required when used with DITRA-XL. If the SCHIENE or RONDEC will not be used, the edge of the covering assembly should be approximately flush with the drip lip of BARA-RTK.

4. When using a bituminous, flat sheet-applied, or trowel-applied waterproofing membrane, the trapezoid-perforated anchoring leg of BARA-RTK is bonded to the sloped screed at the exposed edge area with a suitable thin-set mortar. To prevent a slope reduction at the edge area, apply a gradient transition layer of thin-set mortar between the screed and the profile. The waterproofing membrane is carried over the cut-back channels in the bonding flange and bonded with a suitable adhesive. When installing the waterproofing membrane, the instructions of the manufacturer must be observed.

5. Covering assemblies installed over a waterproofing layer may consist of a drainage membrane with a load distribution layer (e.g., mortar bed) on top, a gravel layer, or large-format pavers supported by pedestals or stilts.

6. Please note: Prefabricated corners and connectors are available for inside corners, outside corners, and butt joints. Abut the ends of BARA-RTK, leaving an approx. 3/16" (5 mm) joint. Cover the joint with the clip-on connector.

7. Once the covering is completely installed, the BARIN gutter system can be fastened to the BARA-RTK profile using the included screws. The slotted holes allow for establishing the proper slope, if required.

BARA-RTK requires no special maintenance or care. The coatings on the color-coated aluminum profile are colorfast and UV-resistant. Damaged surfaces shall be painted over.
