I used sour smelling paint on my walls in my spare bedroom about 2 months ago and the smell is still there even after I used fresh paint and put two more coats of the fresh paint. What should I do.? Is it safe to be in that room.? It isn't as bad as it was but you can still smell it.
Honestly you might be re-drywalling the whole room. If you smell sour that is basically mold. If you can smell it then it must be producing mold in the air which affects your family. So you have two choices:
Obviously using the paint was really dumb. My rule is if I have to ask myself if I should use something or not, I don't unless a pro or research says its OK.
