Hello,

I'm looking for information about finishing my basement ceiling. I
plan to finish only 1/2 of the basement (an area 17' x 37' rectangle)
I only have one water pipe in that area that goes to the back
unfinished area. I also have a few heat ducts, but otherwise, the
joist pockets are clear of obstructions. I was considering painting or
staining the joists, then running a 2' border of drywall around the
perimeter (to simulate a coffered ceiling look). I'd also cover the 3
ducts that run between the joists with drywall. For the underside of
the plywood subfloor above, I was considering spraying it with joint
compound thru a compressor driven gun. Maybe a knockdown or popcorn
effect. My question is weather joint compound will stick well to the
plywood subfloor? Maybe even skip painting the joists and just hit
them with the compound too? Does anyone see anything the might make
this un-doable?

Thanks,
Ted
