question to our pro's and the rest of the TIA crew. after a weekend of rain and storm the weather goes slighty back to normal 75 degrees and sun. finally i can go back to my local hardware store and buy couple more drywall sheets to finish my dining room. after that i can apply tape and mud, and sand it smooth. i can borrow my friends hopper gun to apply the texture on the wall; this one requires 2.4 cfm @90psi the wall is not that big, so i was thinking to use the tiny PC pancake compressor from him which i have left from the framing job. but that one has the same cfm rate than the gun. and 4gal is not that much. i was thinking to apply the texture with the hopper gun until the pressure gets too low to go on. then wait until its back filled. or do i need a bigger compressor like 15gal, 20gal to tackle that job with around 5cfm@90psi?
