Has anyone had to deal with this problem? Builder has ceiling lights that are to be flush with surface of drywall with no trim over the dry wall. It is impossible to cut and install drywall with no crack between drywall and light housing. At best you will have a 1/8 or greater crack. They want no build up, on the surface, of tape and mud to fill that crack. They want no caulk used on the surface. Can you almost fill the gap with caulk, then, float some drywall mud in the remainder of the gap, with no excessive buildup of mud on the surface? Will the mud stick to the caulk? Will the drywall mud not crack with out tape?
