Schlüter®-BEKOTEC-EN 23 F


  1. Schlüter®-BEKOTEC-EN 23 F is installed over an even and sufficiently load bearing substrate. Larger uneven sections should be levelled with screed or suitable fill materials prior to installation. If required, install additional suitable insulation materials on the substrate, observing the applicable regulations for sound and/or heat insulation. If cables or pipes are installed on the load bearing substrate, install a full layer of sound insulation in accordance with DIN 18560-2 above the levelling layer. Observe the maximum compressibility CP4 (≤ 4 mm) when selecting a suitable insulation material. If the construction height does not allow for using polystyrene or mineral fibre insulation, the Schlüter®-BEKOTEC-BTS sound insulation membrane with a thickness of just 5 mm can achieve a significant improvement in sound insulation.
  2. Adhere the 8 mm edge strip Schlüter®- BEKOTEC-BRS 808 KSF in places where the covering adjoins walls and other construction elements. The edge strip features an adhesive segment on the top and bottom for secure attachment. The adhesion on the substrate or the top insulation layer and the pre tensioning of the integrated foil leg push the edge strip toward the wall. When the studded Schlüter®-BEKOTEC panel is laid on top of the adhesive strip, the panel is permanently adhered to the substrate and flowing screed can no longer get beneath the panel.
  3. The Schlüter®-BEKOTEC-EN 23 F modular panels must be cut to size in the peripheral areas. The Schlüter®- BEKOTEC panels are connected by overlapping a row of studs and clicking the panels together. In door transition areas and near distributor boxes, the smooth levelling panel Schlüter®-BEKOTEC-ENFG may be used to simplify the pipe installation. This panel is used underneath the studded panels and is adhered with double sided adhesive strips. The self adhesive pipe clamping strip Schlüter®- BEKOTEC-BTZRKL allows for precise routing of pipes in these areas. It may be necessary to adhere the panels to the substrate, for instance if the force of the pipes is relatively high (in small rooms with tight pipe radiuses). The double sided adhesive tape Schlüter®-BEKOTEC-BTZDK66 can be used for this purpose.
  4. To create a Schlüter®-BEKOTECTHERM ceramic thermal comfort floor, the system pipes with a diameter of 14 mm are now clamped between the cutback studs. The spacing of the pipes must be determined on the basis of the required heating output, as shown in the Schlüter®-BEKOTEC heating diagrams.
  5. As part of the screed installation, cement screed with strength class CT-C25-F4 (ZE 20) or calcium sulfate screed CA-C25-F4 (AE 20) is installed with a minimum screed cover of 8 mm over the studded panels. The flexural strength of the screed may not exceed F5. The screed thickness may be increased to a maximum of 25 mm above the studs for levelling. To avoid sound transmission between individual rooms, the screed should be separated at the threshold using the expansion joint profile Schlüter®-DILEX-DFP.
  6. As soon as the cement screed is ready to support weight, the uncoupling mat Schlüter®-DITRA may be installed in accordance with the manufacturer’s recommendations (see product data sheet 6.1). Calcium sulfate screeds may be covered with Schlüter®-DITRA as soon as they have reached a residual moisture level of < 2 CM-%.
  7. Ceramic tile or natural stone can be directly installed on top of the Schlüter®- DITRA, using the thin-bed method. The ceramic covering must be divided into fields with movement joints above Schlüter®-DITRA in accordance with the applicable regulations. We recommend the movement joint profiles Schlüter®- DILEX-BWB / -BWS / -KS / -AKWS for creating movement joints (see also product data sheets 4.6, 4.7, 4.8 and 4.18).
  8. Our corner movement profiles Schlüter®- DILEX-EK or Schlüter®-DILEX-RF (see product data sheet 4.14) can be used as a flexible edge joint in floor to wall transition areas. The protruding sections of the Schlüter®-BEKOTEC-BRS edging strip should first be trimmed.
  9. The Schlüter®-BEKOTEC-THERM ceramic thermal comfort floor is ready for heating just seven days after the completion of the cover assembly. Increase the supply temperature by a maximum of 5 °C a day to reach the desired operating temperature, starting from 25 °C water temperature.
  10. All other covering materials that are not susceptible to cracking (e.g. parquet, carpet or synthetic coverings) can be directly installed over the Schlüter®- BEKOTEC screed without the Schlüter®- DITRA uncoupling mat. The height of the screed must be adjusted to the corresponding material thickness. In addition to the applicable installation guidelines, note the permissible residual moisture level of the screed for the selected covering material.
