Greetings: Sheetrock for walls and ceiling?....... bad idea…. You’ll never be able to hang anything heavy like cabinets, shelves, ceiling lights, etc. without the screws pulling out over time. Walls need something like OSB or something more suitable for shop needs. As for painting…. 2 coats of Kilz, and 2 coats of a flat latex white…that’ll do it. Don’t worry, you ain’t gonna be vacumning the walls, so it really don’t matter what you go with…. do what you want to….. it’s your shop…... keep on keeping on…...... later.
