Schlüter®-BEKOTEC

Installation

  1. Schlüter®-BEKOTEC-EN 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. The 8 mm thick perimeter strip, Schlüter®-BEKOTEC-BRS 810, is placed at the perimeter, where the covering meets wall or fixtures. The foil leg integrated into the edge strip must be positioned between the substrate (or the top insulation layer) and the studded panel. If a flowing screed is to be applied, the Schlüter®-BEKOTEC-BRS 808KF with adhesive leg is used. The edging strip is attached to the wall using the adhesive strip on the reverse side. Placing the screed panel onto the self adhesive foam leg prevents back flow of the screed. 
  3. The Schlüter®-BEKOTEC-EN modular screed panels must be cut to size in the peripheral areas. Use of the special edge board, Schlüter®-BEKOTEC-ENR 1520P (see page 4), simplifies cutting and minimises waste. The Schlüter®BEKOTEC panels are equipped with a mortise and tenon type edge design for interconnection.
  4. To create a Schlüter®-BEKOTECTHERM comfort floor, the system pipes with a diameter of 16 mm are now clamped between the cut back 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 25 (alternatively: Schlüter®-DITRA-DRAIN 4 or Schlüter®DITRA-HEAT) can be adhered, observing the installation instructions of product data sheet 6.1 (alternatively: 6.2 or 6.4). Gypsum based screeds may be covered as soon as they have reached a residual moisture content of < 2 CM %. 
  7. Ceramic tile or natural stone can be directly installed on top of the uncoupling mat, using the thin bed method. The ceramic covering must be divided into fields with movement joints above the uncoupling mat 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. 2 9.1 Schlüter®-BEKOTEC 
  10. Covering materials that are not susceptible to cracking (e.g., parquet, carpeting or synthetic coverings) are directly installed over the BEKOTEC screed without the 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.
