General product information

What this product does

Schlüter-KERDI-FIX is an MS polymer-based elastic adhesive.

It is suitable for creating sealed connections between the bonded waterproofing membrane Schlüter-KERDI and other structural components such as balcony and terrace doors, window elements, sheet metal covers or BARA edge profiles. KERDI-FIX is also ideal for adhering KERDI-BOARD panels to one another or to structural components. In addition, KERDI-FIX can be used for adhering a wide range of other materials.

Consumption values for Schlüter-KERDI-FIX

5 cm connection to upright structural components:

  • Consumption/m approx. = 45 g
  • Yield = 10 m

How to install this product

The application area must be weight-bearing and sufficiently solid. The surface where the adhesive is to be applied must be suitable for adhesives and bonding, solid and free of loose debris. Materials must not include any volatile components that may interfere with the bond later. If applicable, conduct your own testing on site to verify suitability.

Schlüter-KERDI-FIX as an installation adhesive

Apply Schlüter-KERDI-FIX as a line or spot. For complete curing on non-absorbent or extremely dry materials, KERDI-FIX can be moistened with water. Fit together the components to be adhered during the skin-forming time; spraying KERDI-FIX with water significantly shortens the skin-forming time. If necessary, secure the work pieces in an undisturbed location until the adhesive has fully cured.

Schlüter-KERDI-FIX for waterproofing

To adhere Schlüter-KERDI or KERDI system components, apply KERDI-FIX on the substrate and evenly spread it with a finely notched trowel. Fully embed the materials to be adhered as quickly as possible, avoiding all cavities.

We recommend drawing the smooth side of the notched trowel over the KERDI membrane or using a suitable pressure roller for adhering the KERDI material. Make sure there are no air bubbles.

Schlüter-KERDI-FIX as an exposed joint

Properly cover all edges, e.g. with masking tape, prior to applying KERDI-FIX to joints. The tape may not reach into the joint. To avoid three-point adhesion, press a backfill line with a suitable diameter into the joints.

Fill the joint with KERDI-FIX without leaving any cavities. Remove any excess material with a trowel. Then remove the adhesive tape and smooth the joint with the help of water or a suitable smoothing agent.

Note: Exposed joints require maintenance.

What this product is made from

KERDI-FIX is a single-component waterproofing and adhesive compound based on silane-modified polymers.

The material is not classified as hazardous and may be disposed under the waste code 080499.

Material properties and areas of application

KERDI-FIX is odour-neutral as well as UV- and weather-resistant and is therefore especially suitable for use in outdoor areas. The adhesive is elastic, free of solvents and bonds well with most materials such as wood, stone, concrete, metal, glass and many synthetic materials. KERDI-FIX can be used as an adhesive and a sealant and is suitable for connection and expansion joints (not approved for exposed joints in underwater areas).

KERDI-FIX can be painted over with most alkyd resins or dispersion paint types.

In special cases, the suitability of the material must be verified based on the anticipated chemical, mechanical and/or other stresses.

How to look after this product

Unopened containers of KERDI-FIX can be stored for up to 18 months in cool conditions above freezing. Once opened, the cartridges have a shorter shelf life.
