Is sanding Q2 plaster yourself an option?

In advance: We are not interested in baby-bottom walls. We will receive Q2 plaster from the general contractor. From what we've seen from friends, it’s not a bad Q2 plaster. We probably want to apply slightly textured / solid color non-woven wallpapers. According to the site manager, we should make sure not to use wallpaper that is too thin, as this can visually emphasize possible unevenness of the Q2 plaster. You can imagine that. I am now considering whether it makes sense to acquire a multi-sander and perhaps do some touch-ups / smoothing myself in places. Is this a job that a layperson can learn, or should I better leave it alone? Does anyone have a purchase recommendation for a device if we want to try it? Could start in the utility room; not much lost if it doesn’t work out.

Commonly, something like this is called a giraffe (because of the long handle). You can also rent something like this. And yes, depending on skill, you can definitely do it yourself. Please prime before wallpapering; that is almost even more important.

Of course you can sand it. But in places where it might only be painted, you have to skim coat (removing excess beforehand is obvious).

If it's not too bad and the defects are minimal, I would first go over the excess with the trowel. A fleece wallpaper that is possibly foam-backed on the top side forgives a lot. It's best seen in raking light.

Good luck Gabriele

What kind of sanding sheets do I need to look for / buy for plaster? I have a Bosch PMF 350 multitool here. The sanding sheets always only say "wood" or "metal." I haven't found anything suitable for plaster yet. Can I not do that with the device, or where is the problem?

You better not use your multitool. For a clean, wave-free surface, the sanding pad should be as large as possible, otherwise it is difficult to get the wall even. Better borrow a giraffe than try it with the multitool. That's why you can't find suitable sandpaper.

Thanks, 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 a whole house ahead of us, the purchase might be worthwhile. But we don't yet know if we'll do the rest of the house ourselves or have it done. If we buy equipment, we'd probably do more ourselves, of course.
