I'm about three quarters through a whole house remodel which has gone fairly well so far. The sheetrock was put up last week and the taping was done 2 days ago. The sheetrock guys said they were going to fill the nail holes and do a first layer of mud yesterday. However when I went to the house yesterday afternoon, they hadn't been there. My GC who was there said the joint compound was still too wet and needed to dry out more before mudding. The plan is that the sheetrock guys will do one layer of mud tomorrow, and then my painter will come and do layers 2-3, possibly 4, to get a smooth surface, then prime after that.

I noticed that my GC had hung the vanity in the master bath (it's a wall-hung style). It went directly on the sheetrock. I know my GC is itching to install the kitchen cabinets too. They're all currently under plastic in the dining room. My painter wants to prime the kitchen before the cabinets are installed there, which probably means another week due to how long it might to take for the mud to dry in between coats.

If it matters, there's actually going to be very little exposed wall in the kitchen. Three of the walls will be pretty much all cabinets, with a window on one and a backsplash on the other two. The fourth wall has no cabinets but has a large opening to the dining room.

So my question is: do I insist that my GC wait for the kitchen to be completely primed before he installs the kitchen cabinets? Other than being a major inconvenience to my painter who would have to mud/prime/paint around installed cabinets, what concerns should I have if cabinets are installed directly on unprimed sheetrock?
