Hello
We are currently considering how to finish the walls in our new build.
The interior and exterior walls are made of sand-lime bricks, and a few non-load-bearing walls are made of gypsum concrete.
We want to design the walls so that we can avoid settlement cracks for as long as possible. (These are unavoidable in new buildings.)
What options are available?
Applying a plaster finish on the walls
Paintable plaster, roller-applied plaster, or simply smoothing with a drywall finish to Q3/Q4 level and painting
Alternatively, wallpaper and painting
Non-woven wallpaper, non-woven "Raufaser" wallpaper, painter’s fleece
We want the walls to be either smooth or with a light to medium texture (we are still undecided)
It is important to us to avoid settlement cracks for as long as possible. Non-woven wallpapers are the better choice because they cover small cracks and will only tear if large cracks appear.
The application should be relatively easy to carry out by amateurs.
We plan to have the painter do the stairwell and ground floor.
We want to do the upper floor, attic, and basement ourselves because we don’t have enough budget to have the painter do everything.
What would you recommend?
What is the difference between painter’s fleece and non-woven Raufaser wallpaper?
Is the only difference that painter’s fleece is smooth and Raufaser has a texture?
Non-woven wallpapers are definitely preferable to normal paper wallpapers, right?
Thank you for your help

For beginners, it's better to use an orbital sander. It takes longer, but the result is better. You’ll need it anyway for the corners.
Drywall sanders are too bulky, and as an inexperienced user, you’re more likely to create gouges. Do you mean proper orbital sanders or small multi-sanders? (Sorry, I’m not very familiar with these.)
Or what do you think about handy wall and floor sanders, or a convenient wall and ceiling sander?
I also noticed that drywall sanders sometimes have triangular sanding pads. Those are meant for corners, right?
At first, I thought the large drywall sanders would be easier since you can sand a bigger area evenly at once, but what Tolentino says sounds logical to me too—that smaller devices are easier to control.
Otherwise, a completely manual hand sander might also be an option.

which is much easier... at least not if you want the fleece to look really good. And it’s time-consuming. Applying paste to the wall, putting up the wallpaper, aligning it properly, trimming it, pressing the seams firmly. The corners, reveals, and so on.I wanted to add to that: You have the same problem with full-surface skim coating. And achieving a smooth skim coat is much harder than wallpapering. It also takes much longer because of drying times. You get even more dust because you don’t just sand once or twice, but three to four times. The only thing I would agree with is that wallpapering is best done by two people, while skim coating and sanding, if you know how, can be done well alone.W

However, I can say that the developer would not have agreed to that either; a core drill hole for the range hood was also strictly prohibited.
Everything related to the energy calculation was completely rejected. A vented range hood also blows all the heat outside. In contrast, a decentralized fan with heat recovery improves the energy balance because it retains 80–90% of the heat, whereas with a window, 100% of the warm air is lost.

xMisterDx9 Jan 2023 14:27It always depends on how skilled you are and how quickly you learn.
If I have to fillet 100 fish, it makes sense to practice slowly with a professional knife on the first 5 fish and then finish the remaining 95 fish quickly... rather than struggling to fillet 100 fish at a snail’s pace with a small knife that’s not designed for this task.
Honestly, there are plenty of practice surfaces available. For example, areas where cabinets or shelves are going to be installed anyway.
If the result looks bad, that’s okay. But if it looks acceptable, you’ve saved a lot of time.
And to be honest… 100 m² (1,076 sq ft)? You can manage that with a random orbital sander, or you probably won’t even be able to cover that much area in a day with one.

As an amateur, you will never get painting fleece perfectly applied. Especially not if you have to cut it around corners or awkward spots, ideally external corners.
And painting fleece, which ultimately creates a level 4 (Q4) finish, allows no forgiveness. Every small imperfection stands out all the more.
