ceiling paint cracking
hi,
i removed my popcorn ceiling and now i'm in the process of repainting.
i have a weird problem - my ceiling paint is cracking. i peeled away the paint and the common theme is the paint is cracking wherever there are patches on the ceilings drywall. how do i fix this?

Welcome to the forums!
What prep did you do after removing the popcorn? Did you use a primer?
Your paint seems to not be bonded with the drywall. The fix would be too scrape off all the loose, prime those areas with Zinnser's Gardz or an oil base primer, skim coat with j/c as needed, prime and repaint. Priming first might not be needed but since you've already have peeling it's best to play it safe.

the only prep work completed was sanding
thanks i'll try out your approach
j/c - joint compound? sadly - it appears that wherever j/c was used is where the paint is cracking
i'm curious - what is the purpose of skim coating with fresh j/c?

Joint compound deteriorates when it gets damp although it will reharden some as the moisture evaporates. I suspect the j/c wasn't as solid as it needed to be or it was chalky, either way it wasn't a good substrate for the paint. Gardz [or oil base primer] will fix that.
After you've scraped off the loose you'll have a ridge or depression where there is no paint. A thin coat of j/c will level it off so after the painting is done you won't see where those areas were.
