ᐅ Repairing Q3 plaster, filler compound, and primer

Hello everyone!

The interior of our house was plastered in Q3 quality—apparently quite decent (according to our building consultant). The walls appear very even, although the texture varies slightly in some areas. There are spots where the solid components (aggregate – fine sand?) of the plaster are visible on the surface, and other areas that look completely smooth—these smooth areas are slightly recessed (shrunk a little during drying due to lack of aggregate). But only minimally.

Now to my questions:
Is there a filler or putty that has this slight texture, which we could use to cover the “too smooth” spots? I’ve only found fillers that aim to make the surface very smooth—but that’s not what we want.
Should the primer be applied after filling, or possibly before?

We don’t want to fill and sand everything—we actually prefer not to have a perfectly smooth surface.

Thank you very much in advance!!!

Is this what you are looking for?
Close-up of a white, textured plaster wall surface.

If yes, this is Sto Sil Putzgrund, applied as a brush plaster. It is rolled on and then immediately textured by a second person using a large brush or ceiling brush in broad strokes. It replaces putty and wall paint but can still be painted over later.

I think that might be too much texture already. But it could be worth a try if it can be filled with putty (?).

Some areas feel like very fine sandpaper, while others are quite smooth without texture and only slightly recessed (where there is no grain on the surface). I believe these differences might still be slightly visible after painting. Maybe I also need to apply putty and sand it a bit more coarsely so the putty doesn’t become completely smooth...?

The description does not sound like Q3, especially not of good quality.

Have you discussed your observation with the plasterers? If so, what did they say?

If not, why do you want to try to fix it yourself? It can only go wrong. By the way, one or more pictures would also help.

For my part, I would guess it was not sanded (enough).

That's right, it wasn’t sanded at all. Our building consultant/inspector says the quality corresponds to Q3. The few flaws could be criticized, but you could also fill them yourself.
The indentations I’m talking about are really minimal. They wouldn’t be visible in a photo.

However, I’m unsure if they might be visible later after painting when viewed in grazing light, because some areas appear slightly more matte than others.

But maybe I’m just overthinking it again…

I have never heard of Q3 without sanding. It sounds more like Q2. I wouldn’t even paint directly over Q3 – it just doesn’t look good. What is wrong with using a fleece?
