Hello all,
I’m getting near the finishing stage on a frame and panel entertainment center. I need to apply a water based stain, followed by orange shellac and a wiping polyurethane top coat. I’m concerned about getting and even finish and color, especially in the corners where the panels meet the frames.
Has anyone tried finishing prior to assembly? Any recommendations?
Thanks

I stain before assembly whenever possible (which is always, when doing frame & panel pieces). since it is difficult (as you note) to get an even stain using wiping stains. I apply the oil/varnish coats after assembly, as the oil will interfere with gluing.
I'd assemble first if I was spraying colored lacquer, but that isn't what you asked...
Thanks Paul.
You should stain and seal the panel before assembly.
I prefinish the interior only of carcase work prior to assembly. I dry assemble the piece and make a few light fine pencil marks to indicate where I must avoid applying finish in order to avoid interfering with glue surfaces. I then lay the pieces out flat and apply lightweight (3-M blue )painters' tape to the areas which will later be glued, setting back the tape about 1/32" back from the joint line. After removing the pencil guide lines, I apply the finish, remove the tape , allow plenty of time for the finish to dry, then glue up the assembly. The outside I finish after glue up to avoid damage from cauls biting into the new finish and to allow for any sanding, planing, or whatever that might be necessary after the glue has dried. I clean up any glue squeeze out on the interior, finished surfaces by wiping repeatedly with totally wrung out damp paper towels (use a piece for one spot of glue and throw it directly in the trash and reach for another). Wrapping the barely damp paper towel over a pick ,a small screwdriver, or even a razor blade allows me to get every bit of sqeeze out out of the corners. Once every trace of glue is removed from the finish. I dry the area thoroughly. I babysit the glued up assembly for 1/2 or so after clamping, going over the interior joints repeatedly to catch any late emerging squeeze out.
Good Luck!
