ᐅ Plastering work in Q2 – painting work to follow?

I completely agree with you. I’m really looking forward to the interior plaster... I should be able to share some photos by the middle of next week. I hope it’s applied so smoothly that we can easily use a textured roller finish on top.

Will your entire house be plastered? I’m asking because, as far as I understand, in our timber frame prefabricated house only the "joints between the panels" are plastered.

I was on site briefly this afternoon, and the attic floor is almost finished.

Yes, fully plastered with Q2 finish. I think it looks pretty good. I’ll need to take a closer look when I’m alone in the house 😀

PS: it wouldn’t be possible for us otherwise, since we have a brick solid construction — in other words, not a prefabricated house.

Can I apply just any dispersion paint on a textured roller finish, or do I need to use a "special" type of paint here?

You just need to make sure that the first paint layer (textured paint) is compatible with the second one.
At the time, I applied it with a wide brush in a cross pattern, which we liked. This creates a subtle texture that covers minor surface flaws well. It worked perfectly even in the corners. I would recommend that each wall is painted continuously by the same person to avoid visible differences in brush strokes. Using a roller seems more complicated to me. I saw in a video that you first apply the textured paint with a roller and then add the desired texture with a special "finish roller" (there are many types). We didn’t use a trowel or spatula for this. The Haering textured paint probably doesn’t differ much in application from others.
For the ceiling, I once used a 2mm (0.08 inch) version, which wasn’t so good because the grains didn’t distribute evenly, creating patches with more sand.
That’s why my favorite tool for this is a wide brush.

I really find it unfortunate that Q2 finishing varies so much, making it impossible to give reliable recommendations for non-professionals like me.

It’s always people doing the work, and their varying craftsmanship skills make a difference. In your place, I would focus on what result you want and whether you want it perfectly smooth. With plaster (and drywall) you should also keep in mind that depending on the lighting, you’ll see some small imperfections like waves or fill work.
I mistakenly chose "ready for wallpaper" quality level, and now I see that you could basically wallpaper over anything. Some areas probably meet Q2, while others are closer to a lower level — but overall, it hardly shows on the whole surface. 😀

Those are just filled and not fully plastered either.

1. Simply apply EasyKnauf roll-on plaster (fine texture)
2. Painter’s fleece underneath and then apply EasyKnauf roll-on plaster (fine texture)
3. Painter’s fleece underneath and then paint with regular emulsion paint
4. Apply woodchip wallpaper and then paint

Options 1 and 2 you can forget about—in other words, don’t do them. I’ve mentioned this here on the forum before. In my opinion, and for normal requirements, it’s rubbish. Back in 2009, I “decorated” my small office like this. I think it was 0.5 mm with a cappuccino-colored tint. Now it looks like some undefined mix of white/mint green/yellow (north side). The texture is also very sharp-edged! Never again! Roll-on plaster is suitable for utility basements (ceiling/walls). That’s what it’s good for. Buy a white brand from a home improvement store and that’s fine.

Walls can be uneven even if you want a smooth finish, and simply painting them can look terrible.

I’m guessing this is a DIY project. Have you ever filled, painted, or wallpapered before?

This will only be skim-coated, not fully plastered.

You can already cross out points 1 and 2 in the sense of "don’t do it." I’ve mentioned this here in the forum before. In my opinion, and even for standard requirements, it’s "junk." In 2009, I "improved" my small office with it. I think it was 0.5 mm (0.02 inches) grain with a cappuccino color additive. Now it looks somewhere between white, pale green, and yellow—basically undefinable (north side). And the texture is sharp-edged, too! Never again! You can use textured paint (“roller plaster”) in utility basements (ceilings/walls). For that, the stuff is fine. A generic brand from a hardware store in white does the job.

Walls can also be uneven under "smooth" finishes, which can look terrible with just paint.

I’m reading this as DIY work. Have you ever skim-coated, painted, or even wallpapered before?

So I gather that you would definitely use a paint-grade wallpaper or textured wallpaper?

I can hardly imagine it looking that bad… I know several houses where, after a Q2 gypsum finish, the walls were painted only with textured paint, and I don’t think it looks "junk" at all… But I guess that’s a matter of personal taste.

In our basement, we have already skim-coated and sanded all ceilings, wall joints, and even large holes multiple times.
I’ve also painted the concrete walls in the basement with emulsion paint after the skim-coating.
Wallpapering? That was more than 10 years ago, done with my parents xD

Is it correct that you can’t work with roll-on textured plaster the same way as with dispersion paint? In other words, is it harder to apply? Can one person prime corners, edges, and difficult spots while another applies it broadly with a roller? I heard from a friend that applying roll-on textured plaster might not be suitable for DIY beginners...

Maybe I can add something about roll-on textured plaster. Skip the one from Knauf and buy high-quality roll-on plaster, not the hardware store stuff. For example, I used Haering’s Deko-Quarz eleven (available in different grain sizes).

You can mix the roll-on plaster yourself with matching tinting colors. Application is basically the same as with regular paint—you just have to apply more pressure. Use a long-nap roller. The plaster goes on very easily—unlike what @motorradsilke seems to suggest.

Do not let different people work on corners and edges separately. Otherwise, you might see a difference in texture. That said, you only need to prime corners with a standard brush and the roll-on plaster, then go directly into the corner with the roller. It’s just like painting.

This is a really good solution for Q2 finishes, since you can’t fill dimples but small unevenness disappears under the plaster layer (always apply two coats).

If you ever want to change the color, just repaint or roll on a new layer of textured plaster. No special surface treatment (like a neutral paint coat) is needed beyond a standard primer.

P.S. I have applied this to several hundred square meters, not just in my current house.
