Is fine plaster (Q2 lime cement or gypsum) sufficient for living space?

Plastering and painting work are the things you see afterwards.
Therefore, I would not let myself be tempted to compromise.

I showed the pictures here to my better half and she thinks everything is still too rough. She would like it to be really smooth. However, I wonder how that is supposed to be achieved. Would that then be Q4 or is it only really smooth with a painting fleece or something like that? But doesn't a painting fleece look like wallpaper?

What was shown here in terms of images, I would also, please don’t misunderstand, categorize at most as "meh."

With fine plaster you can achieve quite a lot. It’s important to first deal with whether you want to use gypsum or lime-cement. Personally, I am not a fan of gypsum.

Completely smooth: 1. Use gypsum plaster and a skilled plasterer 2. Lime-cement with fine plaster and trowel, sand down grains 3. Optional --> wallpaper over or renovation fleece, possibly fill seams

I discussed with my plasterer beforehand how I wanted the plaster. Fortunately, he then delivered accordingly. Q2 or Q9 or whatever was never mentioned. For me, more than 1000 sqm of walls were plastered only.

What was shown here in pictures, I would also, please do not misunderstand, classify at most in the category "meh".

But it is what it is: everyone has different taste and pain thresholds!

I showed the pictures here to my better half and she said it’s still too rough. She would like it really smooth. However, I wonder how that can be achieved. Would that then be Q4 or is completely smooth only possible with a painter's fleece or something like that? But doesn’t a painter's fleece look like wallpaper?

Tell her: It’s like with you, honey: the smoother, the more elaborate... I also like you slightly wrinkled... Karsten

is that a photo of the scraped plaster, or something else on it?
