When you say ceiling paint are you meaning a latex paint which is used for most interior painting? Are you trying to reduce the smell and volatile organic compounds? I would think latex would have a lot less VOC's so that would help if your wife is bothered by the smell or the chemicals being released by the paint. Some people are bothered quite a bit by that. There are low or no VOC paints on the market. Google low or no VOC paints and you'll see some opinions and products. Manufacturers have reduced the amount of VOC a lot in the last few years. I remember when there was a "bake out" procedure to be used on entire buildings to reduce the VBOC levels before you could occupy a new space. I don't see that talked about much so perhaps the lower levels in the products are working.
