Correctly remove paint on plaster
Paint that has been applied directly to the plaster is usually quite difficult to remove. But with a little effort and the right tricks, you will succeed.
Plaster isn't just there to be even Underground for Wallpapering but also to ensure balanced humidity in closed rooms. Plaster is definitely not intended to be painted over directly, because the paint is quite difficult to remove from it.

- Then take a spatula and just carefully scrape the paint off. You will be able to pull them off pretty easily.
Conclusion: It is always possible to remove old layers of paint from plaster. Actually, you should never paint this surface directly.
