My father owns a manufacturing plant and a cabinet shop that is 1 block from the plant. To make things run smoother he looking to move the cabinet shop and have everything under one roof. To make that happen I will be building him a 12' deep by 16' wide paint/finish room off the end of the plant. I know you can buy them premade but the fact that I have to build off of the building to begin with has me thinking I do not need all the extra stuff. The booth will be used for spraying finish on wood only. What kind of exhaust system do people use? Any info that can be handed this way would be great. The cabinet shop has a booth that is 40 plus years old so I don't have much to look at and work with as far as making a new one. I did look at pre made booths but most of them had the door on the skinny side and the pad that I look to use that is off the back of the building is 12' deep and 16' wide, as far as loading the booth with product it would be easier if they had the 16' side to work with. I didn't know if anyone had built their own or if they worked somewhere that had?
