INSTALLATION

All substrates must be clean, even, and load bearing. Bond inhibiting surfaces must be removed prior to the application of DITRA-HEAT. For complete installation guidelines and warranty criteria, please refer to the downloadable Schluter®-DITRA-HEAT Installation Handbook or to the installation video online.

Note: Type, thickness, and format of the tile or stone surface covering must be suitable for the intended application. Minimum tile format is 2″ x 2″ (5 cm x 5 cm).

  1. Using a thin-set mortar that is suitable for the substrate, apply the thin-set mortar (mixed to a fairly fluid consistency, but still able to hold a notch) using a 1/4″ x 1/4″ (6 mm x 6 mm) square-notched trowel.
  2. Apply DITRA-HEAT to the floor, fleece side down. Solidly embed the matting into the mortar using a float, screed trowel, or DITRA-ROLLER, making sure to observe the open time of the bonding mortar. If the mortar skins over prior to matting installation, remove and reapply. Note: It may be helpful to back roll the end of the matting before installation, or place boxes of tile on top of the matting after installation, to avoid curling.

*When using the DITRA-ROLLER, place a weight (e.g., bags of mortar/grout or box of tile) not to exceed 75 lbs on the DITRA-ROLLER shelf. Slowly move the roller from one end of the matting to the other, slightly overlapping successive passes.

  1. Lift up a corner of the matting to check coverage. Proper installation results in full contact between the fleece webbing and the thin-set mortar. Note: Coverage may vary with mortar consistency, angle at which the trowel is held, substrate flatness, etc. If full coverage is not achieved, remove and reapply, making sure to verify proper mortar consistency and application.
  2. Abut end and side sections of adjacent sheets. Note: Aligning the studs on the top of the matting during installation can help make subsequent heating cable installation easier.
  3. The DITRA-HEAT-E-HK heating cables can now be installed. Installation instructions are covered under the DITRA-HEAT-E-HK product page. Note: Tile can be installed directly over the DITRA-HEAT membrane immediately after the Schluter®-DITRA-HEAT-E-HK cables have been installed using an unmodified thin set. Please refer to the Schluter®-DITRA-HEAT Installation Handbook below for complete DITRA-HEAT system instructions.
