Wallpaper or plaster? Which is better in new construction?

At least I have always talked about material pairings and claim that it is almost unavoidable there. These don’t even have to be settlement cracks. Different coefficients of thermal expansion alone cause cracks on the surface. That’s why I also recommend painter's fleece. It turns visible cracks into invisible ones.

I would definitely treat a timber frame house with drywall just like you and xXMisterXx suggested, but not a monolithic wall in a solid house?! A brick wall is a brick wall, a Ytong wall is a Ytong wall, etc. The combination of different material pairings only occurs in the floor and ceiling areas, whereby the floor is usually already covered by the screed. So why worry about the wall, e.g., at a height of 1.5 m? Nobody installs mixtures between brick and sand-lime brick in the middle of the wall, right? Maybe it’s just my lack of imagination/experience that prevents me from sharing your concerns. So no accusation in your direction :-)

It's probably due to my way of expressing myself. I am a complete layman and have probably used the wrong terms. Of course, I meant those cracks that are completely harmless from a structural point of view and can occur through the drying process and material combinations or whatever and are normal. There are painting fleece in different variations. Painting fleece completely smooth or painting fleece with slight grain or texture, e.g. Erfurt Vliesfaser MAXX Sand 217 or Erfurt Vliesfaser MAXX Aranit 212 or Erfurt Variovlies Sand. The painting fleece with slight texture should mask slight unevenness and imperfections better than the completely smooth painting fleece, right? Which brand of painting fleece would you recommend? Are there differences between the brands?

My recommendation is also more general in nature. Simply based on experience with plaster quality and the final result. Not necessarily because of cracks in the wall. But you also have material combinations in solid construction on the ceilings. Concrete intermediate ceiling or drywall due to suspended beams or on the upper floor to the roof. Of course, a trowel cut would be advantageous there, but not all plasterers do that as standard.

So in my opinion, the weight of the fleece is more important for dimples. For bumps and pimples, that doesn't help much, since the whole sheet then stretches. That's why sanding is important.

Which brand of painter's fleece would you recommend? Are there differences between the brands?

I have the smooth Variovlies from Erfurt, a smooth fleece from Action, and a "normal fleece" from Pro[f]home mixed in my place. No noticeable differences. That's why I wouldn't choose the one from Erfurt either (too expensive).

ok thanks so the strength of the material is the most important and you don't necessarily have to pay attention to quality products?? (brand products)

StoTap painter's fleece was recommended by painters in tutorial videos on Youtube, it is pre-primed painter's fleece. What advantage does that have? only that you only have to apply one coat afterwards? about 2.50 per sqm also expensive

then we could also take no-name painter's fleece with a thickness of 150g would 130g or if possible even heavier than 150g also work? or is 150g exactly the right sweet spot?

I have come across different terms in search of painter's fleece.

painter's fleece, renovation fleece, universal fleece, priming fleece that is probably all the same, right? What is glass fleece?

At least that's my experience with the processing and the result immediately afterward up to about a year later. It may be that branded fleece lasts longer or is easier to remove.

Probably, although with my cheap fleece I also only needed one coat on most walls. I sometimes just did a second coat because I still had paint left over.

Yes, in my opinion 150g is just right. I haven't tried 130g, it could also be sufficient. More was too expensive for me again, I can't imagine it being that much better then.

From my point of view (except glass fleece) pure marketing. It might be that different compositions are involved. Glass fleece should be glass fiber fleece wallpaper. Stay away from that. Almost everything said before is invalid with that. It is not vapor permeable, you need special adhesives, to my knowledge also special paint. This stuff is even more durable, but from my point of view not sensible except in special applications.
