I've been doing research on voc free interior paints only to find that some colorants aren't voc free, and some companies make false claims about their paint being voc free. And apparently some voc free paints have other harmful chemicals they don't advertise. I've looked into things like milk paint but it seems to be more for furniture than walls, and it's difficult to use. We can move the birds out of the room while painting, but can't move them out of the house as they have nowhere to go. The whole thing is driving me a little crazy. What kind of paint do you use?
