My husband touched up the paint in our bedroom. The smell was rancid, like sour milk. I cannot believe he used the paint that went bad. I have a horrible headache and watery eyes, an obvious allergic reaction to the mold smell. When the paint finally dries will it all be OK? Or are there lasting issues now with him using the sour bad paint?

Is the paint now dry? How long has it been on the wall? –  shirlock homes Apr 24 '13 at 10:16
    
Yes it's dry now and the smell is finally gone. It's been on the walls for 2 days, but he used that same paint 2 months ago and had the same problem. I made him throw it out this time to not make the same mistake again. I am wondering if it will still have a bad effect on the walls or the air quality in the room since it was paint gone bad? –  user12680 Apr 25 '13 at 23:48
    
Once you have painted over the foul primer with some new paint, the problem should be gone forever. Glad you threw out the old stuff. –  shirlock homes Apr 26 '13 at 8:45

The foul smell is from the volatile organic compounds in the paint decaying. Could very well have mold spores living in it. Whatever you are smelling its going straight into your lungs because smells are particular. If it was me I would get rid of it like it was a plague.
My suggestion is get a heavy duty respirator with the proper filters and a boat load of lacquer thinner. Scrub the walls down with the thinner using towels to get as much of that bad paint off as possible. Then apply two coats of Behr Primer & Sealer to the walls. Finally finish by applying a good brand of paint. Lacquer thinner is hard core so:

  1. cover everything; it will take just about any finish off.
  2. have all your fans running in that room with all the windows open and the door closed.
  3. remove all pets from the home prior to and for several days after the lacquer operation has been completed.
  4. let the walls thoroughly dry out with fans running before attempting to paint.
