I have been frustrated for years trying to spray both sides of cabinet sized doors at the same time. Does anyone have a system that works? We have the racks for large interior doors and that works great. Small doors are a real time waster!
From contributor J:
Hang them from hooks in the hinge openings. You just have to be very careful of runs.
Or the method I see used more often is a nail board. Spray the backs, then quickly and carefully flip onto the nail board and spray the face. There are variations on how to do this. One company makes little plastic pyramids to set things on as opposed to the sharp nail points.
Pre-match sanded doors onto pin boards (face up) and load onto rolling racks. I have approximately 60 pin boards in stock. Racks go into booth with a helper. Helper places pin board with door onto empty turntable #2. Takes door from pin board and places it face down on can. I spray or prime back of door, but not edges. In the meantime he gets another pin board and door onto table #3. He takes door from can, places it face up on pin board #2, I spray edges and face. He takes door from table #3 and puts it face down on can. I move back to can to spray #3 and he racks painted door #2. Door #3 goes back to pin board for edge and face spray, turntable #2 gets reloaded, etc.
After you try it a few times you can get a good flow going. You never want to finish with your doors face down on the pin board. This is especially true with painted or paint/glaze finishes. Always organize your spray run from biggest doors down to smallest drawer head, and always load and unload your racks from top to bottom so you don't have the chance of dust or grit landing on previous door as you would if you went bottom to top. Common sense at play here.
What is the smallest size door you are able to finish? 16 x 18 fridge cabinet doors? What finish product are you using? Are you adding or losing time in a vertical configuration, since I assume you would have to spray lighter coats to prevent sags/runs?
I am currently switching over to Valspar after using MLC for the last few years.
I have made both knock down free standing types as well as wall attached folding types. Though I did do my staining and glazing, etc., in the booth a piece at a time, I finessed the color on the easels. Then, when ready to spray, I would simply spray all the lined up doors at once - normally an 8' to 16' run took me about 5-7 min max, pressure pot and gun. I have not seen or found a better way.
Think of it as a reverse automated flat line spray operation. Instead of the work moving past you as you spray, you're the one in motion. That is what gave me the idea - spraying many pieces without having to move them several times each, and without them taking up needed floor space. Material handling is a profit killer!
