ᐅ Is it possible to apply a Q2 finish to drywall?

Hello everyone,

We will soon have our house finished on the inside with drywall panels, which will be skim-coated and sanded to a Q2 finish. I understand that Q2 can vary in appearance and that factors like perception, lighting, and so on play a role, but can general statements be made on this topic regarding:

- Ceilings: I have increasingly read that it is common to paint them directly (usually two coats), as there tend to be fewer issues with grazing light, seams, etc.

- Walls: We would also like to paint them directly. We are not very particular about the walls but definitely want to avoid wallpapering (if we do, it would be smooth non-woven wallpaper to be painted afterward). What is the best approach here? Are there specific paints or “better” substrates for this? What can end up looking bad in the end? Is it mainly the edges where you can see where one drywall panel ends or begins?

Does anyone have tips? There is also roll-on or trowel-on textured paint, but from my research, that didn’t seem very appealing so far…

Regards

We painted directly onto drywall... first we sanded the transitions a bit – but that already took half a week.
Still, you can see quite a few imperfections in the raking light.

Painting: definitely prime first, then apply regular wall paint.

Have you run out of money???

I don’t understand the last question?! Where do I refer to costs or my available money? I think you really shouldn’t build a house if there’s even a slight chance of running out of money before moving in?!

We are now at Q2 after two applications of Stolevell fill plus fiberglass tape. I actually think this is good enough. However, my brother, a master painter, insists on a third coat of fine filler tomorrow evening. After that, a base coat Sto Putzgrund will be applied without fleece, followed by Sto Altweiss Basic. He says that only very close inspection will reveal the joints between the boards. Since I’m not that picky, I’m fine with that.

You can also spend forever filling... Karsten

So, we have plastered almost up to Q3 level. But the unevenness is still visible. Put in the effort and apply a fleece wallpaper. You will regret it otherwise.
In the bathroom, I filled and sanded the walls. I think I did a pretty good job, but you can still see it. Guests won’t notice, but I do. Eventually, I’ll forget about it in the bathroom. But in the living room, it will bother you.

We applied the first coat of joint compound ourselves and sanded it once. Only in the living room did I do some spot repairs. Then we applied textured roller plaster in two layers or wallpaper plus two coats of paint on top (after priming with a deep primer and a white wallpaper primer underneath). You can’t see any imperfections anymore. We are definitely not experts. I think what we achieved is probably around Q2 level.

I don’t stress about it so much anymore.

This method worked well throughout our entire house.

Textured plaster and woodchip wallpaper with paint cover extremely well. The same applies to fiberglass wallpaper. Q2 finish is effectively equivalent to woodchip wallpaper ready for painting.
