Schlüter-DITRA-SOUND-RSK  Edge insulation strips for heavy duty PE mat

Easy to cut with a utility knife, self-adhesive and above all, effective: Schlüter-DITRA-SOUND-RSK offers clear benefits. The edge insulation strips are attached to rising walls or structural components at the start of the installation. This is followed by the installation of Schlüter-DITRA-SOUND and the floor covering. The floor assembly must not directly abut walls and other structures after installation, but should be buffered by the edge insulation strips.

General product information

How to install this product

  1. The substrate must be load bearing, level and free of components that may inhibit bonding. Any necessary levelling work must be completed before installing Schlüter-DITRA-SOUND.
  2. Cover the edges of the covering at rising walls or structural elements with the self-adhesive edging strip Schlüter-DITRA-SOUND-RSK to prevent stress build-up or sound transmission.
  3. The selection of the cementitious tile adhesive for installing Schlüter-DITRA-SOUND depends on the substrate. The adhesive must bond with the substrate and mechanically attach to the Schlüter-DITRA-SOUND anchoring fleece when curing. A dry setting cementitious tile adhesive is suitable for most substrates. Review any potential material incompatibilities beforehand.
  4. Apply the cementitious tile adhesive on the substrate with a notched trowel (recommended size: 3 x 3 mm or 4 x 4 mm).
  5. Embed the Schlüter-DITRA-SOUND panels, which must have been cut to size beforehand, in the installed adhesive, the printed side of the anchoring fleece facing down. Immediately press them in place with a float or roller, working in a single direction. The curing time of the adhesive must be observed. For efficient installation, precisely align Schlüter-DITRA-SOUND when placing it on the substrate. Install the individual panels with closely abutting joints. Remove any excess adhesive.
  6. Attach the self-adhesive Schlüter-DITRA-SOUND-KB sealing tape over all abutting seams to prevent sound transmission.
  7. To prevent any damage to the installed Schlüter-DITRA-SOUND or detachment from the substrate, it is recommended to protect the area from mechanical stresses, e.g. by setting out running boards (particularly in centre areas used for material transport).
  8. Immediately after adhering the Schlüter-DITRA-SOUND mat, tiles can be installed using the thin-bed method, using a cementitious tile adhesive that meets the requirements of the respective covering. Groove the cementitious tile adhesive with a notched trowel matching the corresponding tile format. All tiles must be solidly embedded in the adhesive. Full contact according to the applicable professional regulations is especially relevant for coverings exposed to high mechanical stresses. Observe the curing time of the adhesive. The adhesive must be able to cure hydraulically or through another chemical reaction in an airtight space without any water evaporation.
  9. Follow the instructions in the data sheet and other relevant technical regulations to install movement joints for perimeter, edge and transition profiles.

How to look after this product

The cementitious tile adhesive and the covering material installed in conjunction with Schlüter-DITRA-SOUND must be suitable for the respective application area and meet the corresponding requirements.

The use of quick-curing cementitious tile adhesives may be an advantage for certain projects.

It is recommended to protect the centre areas, e.g. those used for material transport, by setting out running boards or other protective coverings over areas where Schlüter-DITRA-SOUND is installed.

Notes on movement joints

Separate Schlüter-DITRA-SOUND over existing movement joints.

Continue the movement joints in the tile covering as specified by the applicable standards. Otherwise, divide large coverings installed over Schlüter-DITRA-SOUND into sections, using movement joints according to the applicable regulations. We recommend using the profiles of the Schlüter-DILEX family. Arrange profiles such as Schlüter-DILEX-BT or Schlüter-DILEX-KSBT over existing expansion joints depending on the anticipated structural movements.

Notes on perimeter movement joints

It is important to prevent stress build-up at the edges of the covering, for instance at upright structural components or at floor-wall transitions. Perimeter movement joints and connection joints must be constructed according to the applicable technical regulations and have sufficient dimensions to prevent stress build-up. Install Schlüter-DITRA-SOUND-RSK 630 as an edging strip in these areas. We recommend the various profile types of the Schlüter-DILEX family for perimeter or connection joints at transitions from floor tiles to wall or skirting tiles.
