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

You can, and we have tried it with good results, paint well-smoothed Q2 walls using Sto Sil. Sto Sil is a silicate plaster primer, slightly grainy and fairly thick. It is applied with a roller, then a second person uses a ceiling brush on the fresh white slurry to create large sweeping arcs. Make wide, flowing movements. This technique masks unevenness and gives a nice texture to the wall. Once Sto Sil is dry, it can be overpainted with any dispersion paint if white is not desired. Karsten

Only painting Q2 is noticeable and does not work well. You cannot skip priming either. Applying at least two coats of paint is also necessary. It’s better to apply several thin layers rather than thick blobs. Good brushes and rollers save a lot of time and effort.

Good luck, Gabriele
