ᐅ Clarification question: Can you paint directly over plaster?

Hello everyone,
I wanted to ask the following or see if anyone can give me tips on how to paint gypsum plaster directly. If the construction hadn’t eaten up all the money, I would have hired a professional painter, but there is little to no budget available...
(unfortunately, that’s really the case...)
We have mineral-based gypsum plaster, Multigips 2 Classic. It is troweled smooth. However, you can still see rough spots and small black dots all over the wall.
We tried smoothing the wall using a pole sander and an 80-grit sanding disc, but it didn’t really work. In one area it actually got worse.
How do you fix that? There are many areas on the walls that are very fine and smooth and then other parts that are quite rough.
After that, we planned to prime with Tiefengrund LF (deep-penetrating primer) and paint with Class 1 interior dispersion paint in bright white.
Was using the pole sander the right approach? Or should smoothing be done by hand? Which tool is recommended?
And how do we get rid of these damaged areas?
I will upload photos soon.
Best regards

That may be true. The master painter was at my place today. He said that with Q2, everything needs to be filled and smoothed. Then he would recommend some kind of renovation fleece as a base layer and a silicate resin paint. Of course, sanding twice, priming, etc.
I’m still waiting for the quote. But I think I’ll have to do it myself. I had too many change orders during construction ;-(
Also, there’s another issue:
I’ll just say condensation/moisture on the slab...Of course, a professional will tell you that. A trained specialist only knows smooth or deliberately textured surfaces.
I once had a painter friend who was supposed to paint my bedroom in a stylish terracotta color. I trusted him and went to IKEA. When I came home, I was greeted by a room painted in baby beige.
Tinted white! I meant color, but the professional applied it correctly—white with tinting paint. That, however, had nothing to do with daring color.
Q2 means the surface is ready for wallpapering. When a professional sees Q2 plaster, their mind shifts toward making it smooth, even, and paint-ready. That mindset is creatively counterproductive!
Today, courage and exceptions are part of the standard that makes something special.
My advice: paint a Q2 wall in white or color and observe the dried result. If you like it, continue. If you prefer a conservative approach, have a professional do it. Doing it yourself is an ungrateful and time-consuming process.

It should stay like this throughout the whole house because we already like rough textures, but it just looks... well... adventurous, to put it nicely.
I did the rest myself – Q3 to Q4 in the drywall area.

Adventurous?.. I’m past that stage :P
No, seriously: our Q2 finish was done well, so much so that experts were surprised because it looked like a higher quality level.
However, I’m open to creative ideas and have previously used textured plaster myself, even mixing quartz sand into paint to make the otherwise plain smooth wall look more lively.
We have a mixed style in our home, leaning towards minimalist and industrial design.
That’s why it’s important to continually reflect on your own perspective and how something feels to you, then make your judgment based on that—not on what others consider normal.

Sgt.Lapdance29 Jul 2016 16:19Hello again,
I received a quote from a local painting company for the kitchen, bathroom, and living room – €4,300 (about $4,600).
We had the drywall ceiling and walls painted white before, which could have been left as is, but my wife doesn’t like it. We’re now going with fleece-backed woodchip wallpaper. It hides a lot of imperfections.
Attempts to smooth the walls with ready-mixed plaster didn’t work. Unfortunately, we didn’t reach a "Level 3 finish" (Q3). But I’m not a plasterer either.
The paint is Schulz Classic White – but rebranded from a discount store brand. That saved us another €10 (about $11).
The paint is really good. Alpina is not better.
I also applied a lot of primer – a lot even got onto the tiles and grout.
Thankfully, the splatters came off easily with a cleaning stone (white stone). Whoever invented that yellow sticky stuff should be—
Hopefully, we move in by August 31 – until then,
Best regards
