The correct use of DecoFix glues is very important:

For walls that have been plastered for 12 months or longer, you should use FDP500 adhesive. For newly plastered walls, bathrooms or external areas use FDP700 adhesive. For joints you should use FX400 adhesive.

For Basixx profiles use the FDP700, DecoFix Pro, glue for installation and to seam joints.
