First things first. According to the American Pregnancy Association, a pregnant woman shouldn’t be the one doing the painting. Which means: don’t stick around for any scraping or sanding of walls, which can rustle up lead from the disco-era paint that’s still lurking behind the layers, and make yourself scarce when the painting is actually being done. And, at the very least, the job should be done with Low VOC or zero VOC paints. Water-based (as opposed to petroleum-based) and at no more than 250 grams/liter and 5 grams/liter respectively of VOCs in their flat forms (according to EPA regulations), paints like Benjamin Moore’s Aura and Natura are not entirely chem free, but are much better than many original lines and are tried, true and durable. You can also check out AFM Safecoat for their zero VOC paints, as well as the Greenguard website for paints certified as low emitting. Be aware that tinting a paint can add VOCs to the mix (the darker the color, the higher the VOC content might become).
