in commercial work i do frames, then ceilings and walls, now i am doing residential and i do walls, ceilings, trim but i am thinking trying a nc home, trim, walls, then ceilings and see if its faster... caulk/spray trim right onto walls, mask it off then paint walls and lids. it takes less masking if you spray trim first and mask it off. compared to painting walls and lids then masking off the walls and spraying the trim, or hand painting the trim. has anyone tried this in residential work?
