I'll chime in. We also have Q2 ([Gips Maschinenputz] I believe) and only want to prime + paint.
The surfaces themselves also look quite smooth to me. The question is only what to do with the possible "defects." Here and there there is one or the other notch, but these mostly come from the subsequent trades. If I now make repairs in places with, for example, ready-made filler, the spot is macroscopically smooth but may look slightly different in texture. How will it look after painting?
The same applies to spots where there is no dent, but something on it that would be sanded again? The sanded spots are certainly smoother than the original plaster? (Although it doesn’t seem very coarse-grained to me either.)
Does anyone perhaps have a few example pictures?
