Hello good people!
I started painting the ceiling in the living room of our apartment from '62. It's a textured ceiling. However, it cracked in one spot and it turned out that about 1/2 sqm of the surface layer (i.e., the textured part which is a few mm thick) has completely detached from the underlying concrete.
- Is there a good way to fix this??
- What does this surface layer usually consist of? Plaster, filler??
Attaching a picture of the mess.

Looks like many layers of paint and different kinds of paint. I encountered this once and we never got rid of the mess. Something that was recommended to us was to paint with oil-based heavily diluted and then undiluted. It lasted a year, then it started peeling again. 
Personally, today I would probably put up väv on the ceiling to avoid this in the future.

if it comes off so easily, I would clean the roof down to the bare concrete surface and then paint with white matte silicate paint - the paint adheres well and only comes off if the entire concrete roof collapses . It could get worse if the concrete surface underneath is not smooth and needs to be replastered... then it would be too much work according to my suggestion.

The concrete underneath is not smooth enough to paint on, so unfortunately that suggestion is not feasible... and besides, it seems to hold well in the rest of the ceiling. My thought is to expose the concrete on this half square meter and then try to fill it with something suitable and try to mimic the textured appearance.
The question then is what should I use to fill it and how do I achieve the textured structure?
