I took a couple of spray finishing classes at the local Woodcraft. They took some craft board (looks like a plastic version of corrugated cardboard) and built a booth that is big enough to spray an end table. They used the motor & impeller section of a dust collector to provide suction. The back end was free. We sprayed various oil based finished all day. No explosion proof devices were used.

In my small woodshop, I have hanging plastic tarps (from Harbor Freight) that I can hang from the rafters. I use a 20” box fan to suck air out the door. Here in Saint Louis I spray September/October through May/June. I want the shop in the low 70s. I also have a dehumidifier. For woodworking I almost exclusively spray lacquer and have not had any problems. I was told that lacquer dries so fast that by the time it gets to the fan it has hardened to dust like particles.
