I am totally new to spraying .. I have a basement which is dry and clean, and have been thinking I could use a corner for spraying .. This is a basement under the shop. Not a basement under a house.

The floor and walls are concrete. Ceiling is wood.. So I figured I would throw up some poly on the ceiling and walls. maybe frame up another wall to form a U ..

ceiling height is about 7'6" ..

I have a spray gun. only used it once. I dont picture myself spraying every day.. maybe a couple times a month.. tops..

What do I need to know ?
