ᐅ Attic Conversion / Plastering Drywall Sheets

Hello everyone 😉

We have now reached the attic conversion stage in our new build!! YAY
The boards have been skim-coated, joints reinforced, and the entire surface smoothed!
What should be done next before applying the plaster?
We plan to use Edelweiß Structo Edelputz 1mm (0.04 inches) thickness.

Thanks in advance

The manufacturer should provide instructions for the surface preparation.
