Schlüter-DITRA-HEAT-DUO-PS is an intelligent system solution for uncoupling and heating your tile coverings and saves time and material in installation with its Peel & Stick technology.
Our easy-to-use uncoupling mat Schlüter-DITRA-HEAT-DUO-PS is an intelligent system solution for uncoupling and heating your tile coverings if you need heat quickly, for a short amount of time and a suitable substrate is already installed. It not only offers all the advantages of DITRA-HEAT-DUO (quicker heat-up response and additional sound insulation), but also saves time and material in installation with its Peel & Stick technology.
Schlüter-DITRA-HEAT-DUO-PS features a special 2mm fleece covered in pressure sensitive adhesive laminated to the underside, which, in addition to bonding with the substrate, reduces impact sound and enables a faster heat-up response.
DITRA-HEAT-PS/-DUO-PS is exclusively intended for installation on floors in interior areas. Substrates for installing DITRA-HEAT-PS /-DUO-PS must be flat, clean, dust free, dry, smooth, rigid and load bearing, with no deflection.
To install peel the release film off DITRA-HEAT-PS/-DUO-PS and place the membrane on the substrate.
It can be lifted and re-positioned providing no pressure has been applied to it. However once pressure has been applied the adhesive sticks the membrane firmly to the substrate. The heating cables can be installed immediately after adhering the membrane, using a spacing of 9 cm (every third stud).
The tile covering is installed directly over DITRA-HEAT-PS/-DUO-PS in accordance with the applicable regulations, using the thin-bed method. The cementitious tile adhesive bonds with the cut back stud structure of the DITRA-HEAT-PS/-DUO-PS membrane.
DITRA-HEAT-PS and -DUO-PS are waterproof and are suitable for use in wet rooms, provided the abutting joints are sealed with Schlüter-KERDI-KEBA and Schlüter KERDI-COLL-L. They do not have ETA or abP certification. If certification is required, we recommend using the original Schlüter DITRA-HEAT/HEAT-DUO which is bonded to the substrate with cementitious tile adhesive.
Technical Details:
Installation
1. Always check the substrates on which DITRA-HEAT-PS/-DUO-PS is to be installed to make sure they are flat, load bearing, clean and compatible with the materials to be used. Remove all surface components that may weaken the bond. Any levelling, height adjustment or slope compensation must be carried out before the installation.
2. Thoroughly vacuum the substrate prior to installation to remove all dust.
Note: Although it is not mandatory to apply a primer, if the condition of the substrate necessitates it, a primer suitable for the substrate should be used.
3. Cut the uncoupling mat DITRA-HEATPS/-DUO-PS to size and lay it out on the floor. Now remove the release film from the fleece on the underside and press the mat evenly on the substrate, using a floater or roller.
Note: For efficient installation of product rolls, precisely align DITRA-HEAT-PS/- DUO-PS and keep the material tightly stretched with light tension when placing it on the substrate. Minor repositioning is possible before pressure is applied to the uncoupling membrane. The Easy Cut gridlines of the membrane minimise the restoring force.
4. To prevent any damage to the installed DITRA-HEAT-PS/-DUO-PS material or detachment from the substrate, protect the area from mechanical stresses, e.g. by setting out running boards (particularly in the centre areas used for material transport).
