I finally got around to closing up holes plumbers left in the walls and ceiling of our laundry room. Both are orange peel; the walls being light and the ceiling heavy, but nothing is knowck down. In the past I have always used the spray can texture with just okay results but now I am thinking of getting an inexpensive little hopper and gun from Harbor Freight as I will need to spray 60 to 100 sq ft. (I might use it later for some smaller repairs in one of the rooms.) My question is whether my old Craftsman oil less hot dog compressor is up to the job. It has a 3 gallon tank and is rated for 3.7 CFM @ 40 PSI and 2.4 CFM @ 90. Should I be able to shoot for a second or two and then rest a bit for the compressor to catch up?

We just noticed a section of drywall on our ceiling that seems water damaged. Unfortunately, it's the section right under our 2nd floor bathtub. See photo. The damaged area is right under the bathtub faucet and drain area, so I'm guessing one of those are leaking. First things first, could use help on the best way to remove the drywall, to better investigate the issue. How much would I remove? Horizontal ceiling is damaged, but not the adjacent sloped drywall heading up the stairs. I imagine this area is mostly studs? Thanks in advance!
