Is sanding Q2 plaster yourself an option?

Thank you, I looked into it. I'm torn about buying a device since you can get a decent Einhell sander for around €100, and renting one at Obi for 4 hours would already cost €50. Since we have an entire house ahead of us, the purchase might be worthwhile. But we still don't know if we'll do the rest of the house ourselves or prefer to have it done. If we buy equipment, we would probably do more ourselves, obviously.

Please don't take such cheap junk. What you found is probably a drywall sander, which might be good for smoothing spackled joints between drywall panels, but that's about it. I don't know how big your new place is, but we're quickly talking about 500 sqm and more to be sanded completely!

I would also definitely not take a device without dust extraction (with a suitable industrial vacuum cleaner with filter bags).

Your arms should also be thicker than McDonald's fries. This is real work.

Hmm, I think you can connect a vacuum cleaner there. I would have to check again. But I don't want to sand everything smoothly all over. I would only want to go over rough spots where a few crumbs stick out. I'm not interested in a baby-soft finish at all; we would probably wallpaper some of the living space anyway, I think.

I can only agree with and warn against it. It’s similar when some people talk about sanding their wooden floor themselves at all or even completely. I did it once..... that was a long story.... never again! Also with sanding walls, which was done here about a year ago, I would never lay a hand on it myself. Most likely you will see that later and will never manage to make it look nice. And... vacuum cleaner is not equal to vacuum cleaner and in the end you pay for expensive sandpaper, get annoyed and have a lousy result. You don’t necessarily need baby powder, but coarser sanding marks and sloppy work never look good. At the time I had textured paint from the company Haering with 1mm grain size. If you buy it from the local painter and are shown once how to apply it with a wide brush, you will get a great result and the look also forgives mistakes more easily. If you want, you can apply a glaze on top, depending on your design preference. This is a task that you can easily do yourself. The thing with Einhell and a small sander, etc., I would have the greatest respect for that and keep my hands off. Here with us there is partly fleece wallpaper and paint on top. That is also a good option for doing it yourself, precisely because it forgives more mistakes.

I also bought a sanding pole myself (about €120) and sanded all the walls (Q2) with 120 grit sandpaper. You can feel a clear difference compared to before. However, it is really a strenuous job. I still have to fill some holes. I will then apply a fleece. Whether my work was "good enough" in the end, I will see once the first room is wallpapered.

then I think we would all be happy here if you shared the result. (Maybe even with pictures?)

I can do that. However, this will take a few more weeks.
