Product Options:


Schlüter-DITRA is an advanced polypropylene mat designed for tile installation, featuring EasyCut gridlines and square, dovetailed EasyFill recesses. The mat is reinforced with an anchoring fleece laminated to the underside.

Key Features and Benefits:

Schlüter-DITRA effectively separates the tile covering from the substrate, neutralizing stresses caused by substrate deformation.
It bridges tension cracks, preventing them from affecting the tile covering.

The mat acts as a waterproof barrier, providing high water vapor diffusion resistance.
When properly installed with sealed joints and transitions, it creates a certified bonded waterproofing assembly.
Complies with German waterproofing standards 18531-5 and 18534, suitable for water exposure classes W0-I to W3-I.
Features national technical approval (abP) required in Germany.
Protects sub-structures from moisture and aggressive substances.

Vapour Pressure Equalisation:
The open air channels on the underside allow for effective vapor pressure equalization, accommodating moisture impact from below.

Load Distribution:
Ensures even distribution of mechanical stresses, making tile coverings exceptionally durable.
Suitable for tiles with a minimum size of 5 x 5 cm and thickness of 5.5 mm.
Ideal for high-traffic areas, commercial spaces, and applications with high point loads.
Complies with the ZDB information sheet "Ceramic floor coverings with high mechanical stress resistance."

Bonded Assembly:
Creates a robust bond between the tile and substrate through the anchoring fleece and mechanically interlocked adhesive in the recesses.
Suitable for both wall and floor installations, with additional wall plugs available for enhanced wall attachment.

Installation Instructions:

Ensure the substrate is level and load-bearing.

Install DITRA using a cementitious tile adhesive suitable for the substrate with a notched trowel (3 x 3 mm or 4 x 4 mm recommended).

Fully embed the anchoring fleece and allow the adhesive to cure properly.

Apply the tile covering directly over DITRA using the thin-bed method, ensuring the adhesive bonds with the dovetailed recesses.

Schlüter-DITRA provides a comprehensive solution for reliable, durable, and stress-free tile installation, making it an essential choice for both residential and commercial applications.

Material Properties:

  • Durable and Resilient: Schlüter-DITRA is non-rotting, stretchable, and crack-bridging, ensuring long-lasting performance.
  • Chemical Resistance: The mat is largely resistant to aqueous solutions, salts, acids, alkalis, many organic solvents, alcohols, and oils.
  • Environmental Stability: With a high water vapor diffusion seal, DITRA effectively manages moisture.
  • Safe and Non-Toxic: The material is non-toxic and physiologically harmless, ensuring safety for various applications.

Special Conditions:

  • Chemical and Mechanical Exposure: Product resistance must be verified for specific local conditions based on anticipated concentration, temperature, and duration of exposure.

Areas of Application:

  • Versatile Use: Schlüter-DITRA is suitable for a wide variety of applications, from residential to commercial environments.
  • Chemical or Mechanical Stresses: Suitability must be confirmed for applications exposed to significant chemical or mechanical stresses.
  • Acoustic Properties: Depending on the installation system, stepping on coverings over DITRA with hard shoes or tapping with a hard object may produce a hollow sound.
