Schlüter®-DITRA 25

Waterproofing with Schlüter®-DITRA 25

Provided the mat joints and the connections to built-in elements and upright structural fixtures are carefully sealed, Schlüter®- DITRA 25 can be used to create a certified bonded waterproofing assembly with the tile covering. Schlüter®-DITRA 25 features the national technical approval (abP) required in Germany and bears the Ü mark. Moisture exposure class according to abP: 0 - B0 as well as A and C.

Schlüter®-DITRA 25 has the required European Technical Assessment (ETA) as specified in ETAG 022 (bonded waterproofing assemblies) and bears CE marking. Exclusively use system-approved thin-bed adhesive for areas that require CE conformity or compliance with the general certificate of national technical approval (abP). Please contact us at the address shown in this data sheet for further information about suitable thin-bed adhesive and the corresponding test certificates.

We recommend the use of our waterproofing membrane Schlüter®-KERDI (see product data sheet 8.1 Schlüter®-KERDI) for applications of Utilisation Class B, “pools.” Schlüter®-DITRA 25 therefore protects the substrate from damages due to the penetration of moisture and aggressive substances. The abutting joints are covered with the sealing adhesive Schlüter®-KERDI-COLL-L and Schlüter®-KERDI-KEBA (minimum width: 12.5 cm) is solidly embedded over the joint. For floor to wall transitions, adhere the Schlüter®-KERDI-KEBA in the appropriate width. The sealing band should overlap at least 5 cm.

Schlüter®-KERDI-KEBA is also suited for sealing joints with existing fixtures such as door frames, window frames and balcony edge profiles of metal, wood or plastic.

Start by applying Schlüter®-KERDI-FIX to the part of the fixture that is to be adhered. The remaining width is fully embedded on Schlüter®-DITRA 25, using the adhesive Schlüter®-KERDI-COLL-L.

The suitability of Schlüter®-KERDI-FIX for the material of the corresponding fixtures must be verified beforehand.

Cut Schlüter®-DITRA 25 above structural and seismic expansion joints, then cover the joint with Schlüter®-KERDI-FLEX.

Schlüter®-KERDI-FLEX can also be used for flexible finishing edges. Alternatively, Schlüter®-KERDI-KEBA may be used, provided a loose fold is left above the joint.


Note regarding floor drains:

Schlüter®-KERDI-DRAIN and Schlüter®-KERDI-LINE are components that were specifically developed for connection to bonded waterproofing assemblies. Schlüter®-DITRA 25 can be quickly and reliably abutted in these cases with the use of Schlüter®-KERDI collars.
