Painted walls with old paint and it smells musty?
My DH just painted quarter of our garage with some paint that we bought 1 or 2 years ago. The paint has been sitting in our garage all this time. The problem is our garage is now smelling musty (it doesn't smell like that prior to the painting). We think the smell comes from the paint. We still have 2 - 3 cans of those old paints so it feels like a waste to throw it away.
Will the smell go away if we paint it over with some new paint? Do we need to get special paint, e.g. mildew resistant type?
