One year ago I incorrectly used elastomeric paint on my wood ceiling in my Florida room. I realized it when my helper had already painted half the ceiling. Now portions of it are bubbling up (with water inside) and when I remove the paint the wood underneath looks like it has aged poorly in the last year (like it has been kept humid.

My question is: how do I get rid of the elastomeric paint on the parts of the ceiling that have not bubbled up yet?

Help!
