Wall covering - Aerated concrete Q2, painter's fleece and paint

So our Q2 with painter's fleece doesn't look sh..ty. And it's not bumpy either. It might also depend a lot on the execution itself.

Q2 is defined, maybe you are lucky and had a good plasterer.

Here is an excerpt from a website, links are not allowed.

This surface can, for example, be suitable for medium and coarse structured wall coverings, e.g. wallpapers like woodchip wallpaper (grain RM or RG according to DIN 6742), matte filling paints / coatings (e.g. dispersion paints), which are applied manually ? with lambswool or texture rollers ? top plasters (grain sizes / maximum grain over 1 mm) as far as they are approved by the plaster manufacturer for the respective gypsum board system.

If quality level 2 (standard filling) is chosen as a base for wall coverings, paints and coatings, marking ? especially under grazing light ? cannot be excluded. A reduction of these effects can be achieved in connection with filling according to quality level 3 (special filling).

We also applied Q2 plaster and then wallpapered with a painter's fleece with a 190 floor plan per sqm, it looks very good. We only had to fill a tiny notch here and there, that's it. However, we did not glue the fleece but used paste, so that it might be removable someday. It certainly depends on how well the plasterer does the interior plaster.

Which fleece and which paste did you use?

The fleece was a brand from Malereinkauf, probably only available here in our Rhein-Main area. The paste was from Metylan, NP Neuputzkleister, but before that we primed.

Q2 is a standard that the executing company or the general contractor uses to protect themselves, nothing more.

How well or badly Pavel, Boris, and Bronco can plaster in practice and how much effort they actually put in is unfortunately not defined in Q2. Maybe they use a slightly textured plaster anyway and just rely on that, then you can paint directly without painter’s fleece. Or it looks terrible and, in the worst case, you first have to start creating a proper wall structure with plaster strips and mesh at critical points. That can also be Q2.

Either you agree on Q4 (Q3 is nonsense because the requirements for the actual surface = Q2) or you have to take what comes and then decide how to turn it into an acceptable wall.
