I live in a 1920's home which still had quite a bit of high gloss paint on the trim/french doors which I assume was oil. Because some areas were chipping at the junction with the floor and I was concerned about lead exposure to my baby, I hired a professional painter to repaint it. After originally discussing using lead block, priming and painting, he only sanded and painted with one coat of latex paint. When I voiced my concerns about the longevity and feel of the paint, he said there was no need to prime. Should he have primed? What do I do now?
