I just started to renovate my apartment in an old building. I removed the paint from the walls, but when i started to remove it from the ceiling I noticed it was fitted with polystyrene sheets.
I thought that it was glued, but to my unfortunate surprise adhesive, cement i think. It was used to bind it to a wall.
How do I remove it without damaging the ceiling? I read that chemicals are used on bricks but not sure about wall?
Also underneath cement is from what I can see paint on a plaster (i think its called that in English)
I would be really grateful for any help, or do i have to call somebody with more experience?

C&P from comments as requested:
Epoxy will usually chip off when it is that thick but it is a lot of work. If you can find a proper solvent you could paint it on , I would use a demo drill/hammer with a wide chipping blade. If you have equipment rentals they should have an electric demo drill /hammer is what they are called here like a sds tool with the chisel instead of a drill bit, more expensive than a drill but handy if you do a lot of remodeling.
