I will show how I converted an old dishwasher into a spray paint booth.
Many years ago I replaced my dead dishwasher with a new one. Before hauling the old one to the dump I figured I would try to convert it into a spray paint booth. My at-the-time booth was a cardboard box, with an old cookie sheet, sitting over a large trash can and it did not do well containing overspray. I was desperate for something better and thought I would give this project a chance. My plans included lighting and constructing a lazy Susan platform. I opted out of adding a ventilation system as my usage would be with non-toxic vapors. If you decide to build something similar, and will be using paints with toxic vapors, for safety reasons please install some sort of ventilation system.
