KERDI-COLL-L is a two-component sealant adhesive based on a solvent-free acrylate dispersion and a reactive cementitious powder.

It is suitable for adhering and sealing overlaps of KERDI membranes. In addition, it can be used to tightly seal the edges of the seaming tape KERDI-KEBA on KERDI, DITRA, DITRA-HEAT and KERDI-BOARD as well as on BARA edge profiles.

In conjunction with the materials KERDI, DITRA, DITRA-HEAT or KERDI-BOARD and the matching KERDI-KEBA, installers can create certified bonded waterproofing assemblies.

How to install this product
Apply the material on clean and dry KERDI, DITRA or DITRA-HEAT membranes/mats, KERDI-BOARD or BARA profiles. The suitability of other substrates must be verified and evaluated. Depending on the application, the material can be applied with the smooth side of a trowel and then grooved with a notched trowel of size 3 x 3, 3 x 4 or 4 x 4 mm. If the material is mixed to a thinner consistency, it can be applied with a brush or a roller.

Fully embed the materials to be adhered as quickly as possible (before a film forms on the surface), avoiding all air pockets.

We recommend drawing the smooth side of the notched trowel over the KERDI-KEBA tape or using a suitable pressure roller for adhering the seaming tape. Again, make sure there are no air bubbles.

The application and installation information in our product data sheets 8.1 Schlüter-KERDI, 6.1 Schlüter-DITRA, 6.4 Schlüter-DITRA-HEAT and 12.1 Schlüter-KERDI-BOARD must be followed.

The drying and curing time is shorter in warmer temperatures. and longer at low temperatures.

The ambient temperature for the installation may not fall below 5 C until the final curing. Protect freshly built waterproofing assemblies against moisture, e.g. from rain, until they have fully cured.

Open containers must be used up promptly.
