Q about painting stained wood
I have some ceiling beams that are stained black right now that I want to paint white. I've had a couple painters over for estimates and I'm confused about what they are telling me. One said that there would be a lot of prep involved. The beams have to be sanded and then primed, then painted. Another says that he might lightly sand them but then he would just spray with an oil based primer before painting and that will stick just fine. Which is correct? The prices are very different, and I have no idea if someone is giving me the run around or if the other guy is trying to cheap out (as the one who wants to do all the prep is suggesting). Any advice?
