I was planning to plaster or skim coat a masonry wall made of aerated concrete blocks. But I realize that cracks will soon appear, and I'm not keen on repairing cracks every year. So, I'm considering installing thinner studs and then gluing drywall onto these.
I was thinking of using studs that are only about 2 cm thick. Can I glue these to the concrete, or must they be screwed in?
Does the standard stud spacing of 60 cm work, or does it need to be closer?
Is it feasible to only glue the drywall?
Is there a risk of moisture in the structure? (drywall, air gap, 20 cm aerated concrete blocks, 7 cm mineral insulation, wind barrier, air gap, wood paneling)

The moisture risk depends on whether you have soil against the wall from the outside. If you don't, the risk of getting moisture in the structure is low. I would recommend skipping the studs and attaching the boards directly to the lightweight concrete using the so-called "click method". In this method, you click on, for example, plaster with the same center distance you would have used for the studs, directly onto the board. Stand it against the wall and tap it straight using a straight edge and a rubber mallet. The first board can be tricky, but it gets easier thereafter. Otherwise, a plastered wall is among the most beautiful things you can have in a house. There are systems that don't crack. I can look one up for you if you want.
Good luck.

Why would plaster automatically crack every year?
I don't believe in gluing to concrete, screw it.
Gypsum is probably a much more boring material, the only reason would be if you want to add insulation.

The question was whether I could glue to studs. The reason I want studs is to run electrical behind and I want to avoid smoothing out the unevenness left after removing a cast arch.prototypen said:
The option might be to plaster 2 cm thick, but I have never plastered and I have the impression it's an art. Moreover, all instructions say you first need to know what type of plaster was used before so you don't mix, and I have no idea about that. Or does it not matter? And can the plaster even be applied as if I were spackling?
The walls are in a future guest cottage, so I'm not going to be staring at the walls year-round, otherwise, I agree that a gypsum surface is not preferable.
perrakakel: what kind of system is that? Do let me know about it.
Okay, now we've decided to "click" up drywall panels. Should I use gypsum plaster or what should I take? What are the different pros and cons? Can any plaster "react" against the plaster remnants that remain on the walls?
