I make face frame style cabinets and have started to pre-finish my insides (plywood). After I glue on the face frames, the backs of the frames are not finished. Then I apply a finish to the exterior of the cabinets, which leaves the backs of the face frames unfinished. How does everyone treat this? Do you just leave them unfinished or do you go through the painstaking taping off and finish them? I used to deliver unfinished cabinets and the painting crews would finish them, now I am doing it myself. Any help is appreciated.
From contributor F:
On the cabinets and furniture that I build that have finished interiors, I leave the backs off and then while I am spraying finish on the inside of the carcass I am able to spray the back side of any facing members. I then mask around the edges of the pieces back and spray that so I can still get a glue joint when I put the backs on.
When I build cabinets with melamine or any other type of unfinished interior, I donít bother with applying finish to the backsides of face members. I think I remember reading in the finishing forum years ago that some finishers do apply finish to the back side. I donít think it would be necessary unless the face member was wide across the grain.
We order the drawers, build the doors, build the face frames, spray the doors/FF, cut the box, assemble the box, apply ff, hang doors, and out the door. Not spraying interiors saves so much time and doesn't slow down the other steps of construction. UV cured pre-finish is about as hard as CV.
We use pocket screws to attach the face frames as much as possible. Who is going to stick their head inside a cabinet to check the back of face frames other than another cabinetmaker?
