Pallet of 6 x 25m² Rolls
Practical, time-saving, material saving and, of course, just as reliable in terms of uncoupling, load transfer and vapour pressure equalisation as our classic Schlüter-DITRA: the waterproof uncoupling mat Schlüter-DITRA-PS (PS stands for Peel & Stick) is equipped with a self-adhesive anchoring fleece that allows direct installation on suitable substrates without tile adhesive. This also means you can make flexible adjustments to the positioning during installation – for even easier handling.
The proven "Easycut" gridlines make customised cuts possible. The square undercut recesses in "Easyfill" design also ensure – as in the original – rapid application of the tile adhesive on the top surface.
Uncoupling:
Schlüter-DITRA-PS uncouples the covering from the substrate and neutralises tensions between the substrate and the tile covering that result from various deformations. The material also bridge tension cracks from the substrate and prevent them from affecting the tile covering.
Waterproofing:
DITRA-PS is waterproof and suitable for use in wet areas, provided the abutting joints are sealed with Schlüter-KERDI-KEBA and Schlüter-KERDI-COLL-L.
Note: DITRA-PS has no ETA or abP certification. If ETA or abP certification is required, we recommend using the original Schlüter-DITRA which is bonded to the substrate with thin-bed mortar.
Vapour Pressure Equalisation:
The air channels of DITRA-PS remain open on the underside and so allow vapour pressure equalisation in the event of moisture exposure from behind.
Load Distribution (load induction):
Tiles installed over DITRA-PS in floor areas should have a minimum size of 5 x 5cm and a thickness of at least 5.5mm.
The mortar-filled, square recesses of DITRA-PS transfer mechanical stresses impacting the tile covering directly to the substrate. This makes tile coverings installed on DITRA-PS especially durable. Where traffic loads are high (e.g. in commercial areas) or high point loads are expected (such as concert grand pianos, forklift trucks or shelf systems, etc.), the tiles for each area must be sufficiently thick and have adequate compressive stability. The information and tile thicknesses specified in the ZDB information sheet "Ceramic floor coverings with high mechanical stress resistance", valid in Germany, must be observed.
Tiles in high-stress areas must be wholly embedded in the tile adhesive. The impact of hard objects should be avoided on ceramic coverings.
Adhesive Bond:
The special adhesive layer on the underside anchoring fleece of DITRA-PS sticks well to the substrate, while the mechanical anchoring of the thin-bed mortar in the under-cut square indentations results in an excellent bond with the tile covering.
