1. Screw the luminaire module on the same substructure as the plasterboard.
2. Put a fabric tape into the spatula border intended therefore.
3. Finish the joints cleanly and neatly and use a filler which is elastic enough.
4. Be sure that the plastered luminaire and the plasterboards you want to use are acclimatized and have the same basic humidity.
5. Ground and apply the paint on the luminaire.
CAUTION: The illuminant is not suitable for outside! Do not user the lamp on coarse-grained plaster!
