If "only" textured plaster, no further coating, is to be applied, I would definitely wait until all trades are finished. Due to lack of correction options.
All right. By additional coat do you mean applying paint over the rolled plaster? That would be included with the rolled plaster through the Knauf CompactColour taps, all in one go.
Yes, exactly. If you were to paint regularly and it goes wrong, you can simply go over it again. With [Rollputz] that is not supposed to be painted, this is difficult. A touch-up paint would be different in color and surface and would stand out.
