We just painted with brand new, but gone-bad NO VOC paint (Dunn Edwards in a dark teal). It went on smelling like good paint but when it dried it has a chemical sour smell mixed with vomit and dead animal. We live in the desert (Sedona) so humidity is not an issue. Headaches and nausea are not fun. We sealed all offending walls with 2 coats of sealer primer (BIN Advanced) and another top coat of paint, as suggested by paint company, and it did not fix the smelly problem. Then we got desperate. We have burned two boxes of nag champa incense, as well as cinnamon candles for days. We have washed the walls down with backing soda.... vinegar.... and natures miracle. Everything we do alters the smell, but does not clear it up. Other rooms we painted with lighter tan color of same paint are perfect. The windows have been open for days with exhaust fans going, and we are being held prisoner in the only warm room that doesn't stink. Once the room warms up the smell comes back. After reading dozens of blogs on this issue and hearing over and over that paint company's do not own up to having a fix to this bad no-VOC paint issue, it looks like we may to have to tear down dry wall! HELP .... Any suggestions out there would be helpful before I rip my home apart.
I can't speak to your problem directly but I have had a lot of success with Kilz Oil based primer. It is far from Low VOC and will come with a very strong odor initially. After the paint dries thoroughly the oil smell will subside and you can put on the top coat. I have used this primer to seal pet urine stains on sub floors that otherwise would have had to be removed to get rid of the smell.
