Ceiling with plastering or better fleece wallpaper?

Our painter recommended that we plaster the ceiling since the walls are also plastered and it looks better. What about the risk of cracking? Wouldn't a fleece wallpaper (transparent and then painted white) be better? What do you think? Maybe he recommended the plaster just because it is faster or easier for him?......

Normally, nothing tears there. I would also plaster. Do you have a consistent picture for the walls?

One thing has nothing to do with the other, right?

What is the current condition? Plasterboard filled or raw concrete ceiling? Some preliminary work is also necessary for wallpapering, which is quite close to "plastering."

The ceiling is currently made of concrete. However, there are always joints, which are currently filled with putty. Opinions on this vary. Our plasterer, who also does painting work but is not contracted by the general contractor for us, said he would cover the ceiling with fleece wallpaper, as these joint areas, like predetermined breaking points, always lead to cracks again. In terms of appearance, a plastered ceiling would clearly provide a uniform look. The painter said nothing would crack. Personally, I would prioritize pragmatism over appearance here. If I have cracks in the ceiling later on, the appearance will be lost anyway. I just want to minimize, if not completely eliminate, future additional work.

For this reason, there are classes Q1, 2, etc. for plastering, and to my knowledge, from Q3 onwards, a mesh must be applied at such joints to prevent cracking.

Because even if you simply wallpaper over it now, the wallpaper can tear in those spots (such is the condition in our currently still inhabited rental apartment).

In the end, it will be a question of price. Plastering the ceiling at least to Q3 so that it doesn't crack costs significantly more than painter's fleece, paint, and goodbye.

Working with fleece is defined as Q2. Plaster would be Q3. However, I only partially agree with you: in my opinion, the necessary preliminary work must also be done for "only" Q2. If the ceiling is not smooth, you cannot properly apply wallpaper either. Simply sticking it on would be too primitive. I think the labor effort for plastering is less than for applying the fleece wallpaper. The painter offers me this with plaster at no extra charge. Somehow I believe there is more behind it than just pure friendliness.
