How to determine the correct band dimension?

Proceed as follows when determining the dimensions:

1. Measure the width of the joint to be sealed (at least 8 mm according to the installation instructions).

2. Select the tape dimension so that your measured joint size is optimally in the middle of the application range. Example: Joint width 8 mm → tape width 7–12 mm. This gives you sufficient leeway for natural size changes of the joint.

3. The installation depth must always be greater than the maximum joint width. Joint sealing tapes are constructed according to this principle – for example, dimension 15/7-12: joint width 7–12 mm, installation depth 15 mm. Also consider the surface quality of the joint flanks: For rough or structured surfaces (e.g., plaster), you can use a wider tape with a greater installation depth than for smooth surfaces.
