Plastering work Q2 - Painting work afterwards?

I completely agree with you. I'm really looking forward to the interior plaster... I can also provide pictures of it by the middle of next week. I hope it is so smooth that we can easily apply a roller plaster on top.

Will your house be plastered all over? I ask because in our timber frame prefabricated house, if I understood correctly, only the "joints between the panels" are plastered.

Is your entire house plastered all over? I ask because in our timber frame prefabricated house, if I understood correctly, only the "joints between the panels" are plastered.

I was already briefly on site today at noon and the attic is almost finished. Yes, fully plastered in Q2 execution. Actually looks pretty good in my opinion. But I need to take a closer look when I am alone in the house :D PS: it wouldn't work differently for us at all, since we have a solid brick construction -- in other words: no prefabricated house.

Can I apply any random dispersion paint on a textured roller plaster, or do I have to use a "special" paint?

You just have to make sure that the first coat (brush plaster) is compatible with the second coat. I applied it back then with a wide brush/paintbrush in a cross stroke, which we liked. This creates a fine structure that covers substrate imperfections well. It worked perfectly fine even in the corners; I would only recommend that the same person do it per wall continuously, so you don't see different "strokes" afterwards. Using a roller sounds more complicated to me; in a video I saw that you first apply the brush plaster (roll it on) and then use a "finish roller" (there are all kinds) to create the desired texture. We did not have to apply it with a trowel/putty knife. The Haering brush plaster probably does not differ much in processing from others.
For the ceiling, I took 2 mm at the time, which was not so good, also because the grains did not distribute well there and basically nests with more sand formed on the ceiling.
Therefore, my favorite for that is a wide brush.

I really find it very unfortunate that Q2 varies and thus no binding recommendations are possible for non-professionals like me.

People are the ones doing the work and, of course, different craftsmanship skills also prevail. In your place, I would rather consider what goal I have and whether I want it baby-smooth. With plaster, you should not forget (and drywall as well) that depending on the lighting, you will see some things afterwards anyway, whether it's a few waves, putty work, etc.
I foolishly had "ready to wallpaper" as the quality level appraised, and now I see that you could ultimately wallpaper over anything. In some places there probably is this Q2, elsewhere we probably need to step backward in the alphabet; seen over the entire surface, it hardly shows anymore. :D

Is your house fully plastered? I ask because in our timber frame prefabricated house, if I understand correctly, only the "joints between the panels" are plastered.

That is only filled and not (fully) plastered.

1. just paint with EasyKnauf roll plaster (fine grain) 2. painter's fleece underneath and paint with EasyKnauf roll plaster (fine grain) 3. painter's fleece underneath and paint with normal dispersion paint 4. woodchip wallpaper and paint over

You can cross out 1. + 2. in the sense of "don't do it". I've written this here in the forum before. In my opinion and even for normal requirements this is "garbage". In 2009 I "beautified" my small office with it. I think 0.5 with coffee color additive. Now it's something between white/mint green/yellow, just undefinable (north side). And the grain is sharp-edged too! Never again! Roll plaster can be used in the utility basement (ceiling/walls). That's what it's good for. DIY store brand in white and that's it. Walls can also be uneven in "smooth" areas, where just painting then looks terrible. I read DIY work. Ever filled, painted, or even wallpapered before?

You can already forget points 1 and 2. In the sense of "don't do it". I've already written this here in the forum. In my opinion, and already for normal requirements, it's "junk". I "decorated" my small office with it back in 2009. I think it was 0.5 with a cappuccino color additive. It is now something between white/mint green/yellow, just undefined (north side). And the texture is also sharp-edged! Never again! You can use roll-on plaster in utility cellars (ceiling/walls). That's what this stuff is good for. DIY store brand in white and that's fine.

Walls can also be uneven even when "smooth", where just painting looks terrible.

I read DIY work. Ever filled, painted, or even wallpapered?

So I read that you would absolutely wallpaper with painter's fleece or woodchip wallpaper?

I can hardly imagine that it looks that bad... I know several houses where after Q2 gypsum they have only painted with brush plaster and I think it doesn’t look "junk" at all... But I guess it’s a matter of taste.

In our basement, we have already filled and sanded all ceilings and wall joints, as well as large holes, several times.
I have also painted the concrete walls in the basement after filling with dispersion paint.
Wallpapered once about 10 years ago together with my parents xD

Is it correct that you can’t work with a roller plaster in a similar way as with a dispersion paint? In other words, is it harder to apply? Can one person prime corners/edges/difficult spots and another person roll large areas? I heard from an acquaintance that applying roller plaster is not necessarily suitable for amateurs...

Maybe a contribution from me on the topic of roller plaster. Skip the one from Knauf and buy high-quality roller plaster, not hardware store stuff. For example, I took the Deko-Quarz eleven from Haering (available in different grain sizes).

You can mix the roller plaster yourself directly with matching tinting colors. Applying it is basically the same as regular paint application. You just have to use more force. Use a long-pile roller. The plaster is very easy to apply – unlike

Please don’t have different people do corners and edges. In doubt, you’ll see a different texture. Other than that, you only need to prime corners with a normal brush and the roller plaster, then roll right into the corner. It’s like paint.

For Q2, a really good solution, because although you can’t compensate for dents, small unevenness disappears under the plaster layer (always apply twice).

If you ever get tired of the color, just paint or re-roll plaster over it. Surface pretreatment (painting with neutral color) is not necessary except for the usual primer.

P.S. I have now treated several hundred square meters with it, not just in my current house.
