Painting is done when the interior plaster and screed are dry. There are three work steps: filling, sanding, painting or rolling. Alternatively, one can wallpaper, which shortens the filling. At the very end, the floor coverings are installed. Even when painting, the door frames should already be installed, as work needs to be done around them.
Just want to apply a textured plaster on it. Knauf Easyputz. Do you also need the primer from Knauf for that? Or is Sperrgrund = Tiefengrund and thus other products are also possible?
I find it advantageous to work from top to bottom. The ceilings first. Before filling, if you have to fill anywhere, you should first run the trowel briefly over the surface to lift any excess material. Check surfaces in raking light beforehand.
I think final coating of surfaces is good work because you can see the success so clearly.
