The painting contactor hired by our general contractor mistakenly painted every room in our new home with two coats of exterior paint. They then painted over it with two coats of interior paint before we were made aware of it. Two questions: what is the health risk of that much exterior paint in every room of our home (we have three young children), and second how do they fix the problem? The paint strips right down the wall all the way to the drywall like a piece of plastic coming off.
