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

Black spots?
Unfortunately, I don’t have much experience with gypsum plaster – textured wallpaper is always an option, of course...

Yes. Small black stones... Phew... wallpapering an entire house.

I would appreciate any tips from someone who has done this themselves before.

Best regards

This is what I mean:

Anyone got an idea??

If you paint over it, the spots will probably no longer be visible.

I only sanded with 120 and 180 grit – you must have stayed too long in one spot. Possibly applied too much pressure as well...

You can just reapply the plaster to that area and then sand it again.
