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

No. Still on the topic, Yvonne. For Q2 finish, paint over plasterboard. That’s what it means. Whether it’s plasterboard or wall plaster doesn’t really matter: Q2 is not ready to be painted, only ready for wallpaper. Q2 is still too uneven, and plain wall paint is too thin to hide that. Possibly textured paint. Karsten

We use wallpaper a lot... and want it to be perfect. That’s why we apply Q3 everywhere underneath. The only exceptions are the utility room and the dressing room.

In total, it’s not much more expensive. I estimate around 6,000 to 7,000 euros (about $6,300 to $7,400), but I haven’t received the invoice yet.

What kind of wallpaper are you using? Patterned wallpaper? Then you need a Q3 finish. Woodchip or fiberglass wallpaper only requires Q2.

We have Q3 and fleece. It looks perfect.

All are non-woven wallpapers (I believe it's the same for patterned wallpapers). We sometimes paint over them..

The fleece must meet Q3 standards.

We are currently working on this topic as well and here is our experience and approach: Our painter is applying Q3 finish to the bedroom, large hallway, small corridor, living room, and kitchen (we currently have good to very good Q2 finish). After that, we will apply our desired paint color or a photo wallpaper, but before that, a waste paper wallpaper will be installed on the wall. In the other rooms, we sanded down areas where there were rough edges and filled small holes. Afterwards, we painted twice with drywall primer (white), and it looks great. From our experience and from talking to the painter, a lot depends on how the walls were handed over and personal expectations.
