What to do with basement ceiling?

[GabeBli]

In one of our basement rooms, the ceiling looks like in the picture. Unfortunately, it is not watertight and releases small stones. The room is intended to be used as a gym with various machines, so I would like to retain as much ceiling height as possible.

What would you do with the ceiling to make it neat and tight? Suspended ceilings look nice but add some bulk. Gypsum plaster? I've plastered the walls but I'm really not a professional though. I've understood that it's more difficult with ceilings.

Help and tips are gratefully received.

Looks almost like those asbestos tiles they had on the ceilings in school when you were little...

When was the house built and what was in the room before?

The house was built in 1961. It was used as some kind of hobby room before we moved in a year ago. I sanded the walls and ceiling due to suspicion of plastic paint, then plastered the walls with diffusion-open mortar.

I'm not particularly "harig" when it comes to asbestos, but I would definitely send in a sample of that...

Plaster on Träulit, completely harmless, putty and paint.

Wood wool boards are in the ceiling, they can be plastered well.

Ps. Hope you have a functioning drainage system if you've used gypsum plaster on the basement walls.

Träullit boards in the ceiling can be plastered.

Ps. Hope you have working drainage if you've used gypsum plaster on basement walls.

What kind of plaster do you recommend? Heard from someone that gypsum plaster is easier to work with? Is it tricky to plaster a ceiling or can an amateur manage it?

The basement walls are not plastered with gypsum plaster but with diffusion-open plaster.

Gypsum plaster is, as you write, easy to work with. In the ceiling, there should not be any moisture load, so it should work.

However, I have never plastered a ceiling, so I can't give any tips on methods, etc. I have plastered numerous walls with both traditional plaster and gypsum plaster. My experience is that the gypsum plaster is more forgiving and adheres well, which is an advantage when you're inexperienced.
