6×6 sounds too small unless you do only craft size items. You need room to work all around the piece. I use a turntable for most of my spraying, that way I can spin the piece so I am always spraying towards the exhaust fan.

You must filter the incoming air, control temps and use explosion proof lighting and fans. You will also appreciate having lots of good (especially raking) light to check your finish as you spray. Be sure to mount an air regulator in the booth along with a moisture seperator unless you plan to go HVLP with its own blower.

Water borne is the way to go for most hobbyists, much safer and easier cleanup.

+1 Seems really small. Booth needs to be 2-3 feet larger (on all sides) than largest item you be spraying. Even if you use a turntable, still need 4 feet clearance on front and 2-3 feet on sides. For something that small, might want to consider a Rockler HomerRght shelter?

+1 Explosion proof lighting and ventilation units if using flammable solvents.
Don’t forget about explosion proof ventilation for the room where you open cans, and mix in solvents to prep for spraying.

PS – There is huge difference between creating a permanent insurable spray booth, and spray room for home use.

Commercial spray booths are very expensive, $50K+. The are designed with perfect lighting, safe airflow, EPA approved filtration, fire suppression, and panels that easily collapse outward in case of pressure due explosion to minimize compression damage to occupants. Check your local EPA requirements for spray booth as well. Most all states/counties require permits to dump solvent fumes into air.

Part time use spray booths in garage are easy to make, depending on your personal safety requirements can cost anywhere from $100 to a few thousand. There are a ton of existing WWW articles available on this topic.

Best Luck.

If this is a permanent installation you should check with your local building codes. In addition to the safety items mentioned above most of they require a fire suppression system (sprinklers). Failure to do this could also affect your insurance coverage in the event of a fire or explosion.

I have a “temporary/permanent” spray booth for my shop. Using 6 mil thick 10×10 plastic sheeting, i made roman blinds out of the plastic sheets, and attached them to the ceiling. They stay rolled up at the ceilings and when needed they easily unroll to the floor. I use an800 cfm suirrel cage blower in a box with 2 25”x25” filters I only use 3 walls, and use the blower to pull air in and filter overspray. No dust problems. I spray solvent lacquer and shellac some when I can ventilate well- warm enough outside. Spray a lot of waterborne in the winter. I turn the blower on about 30 min before spraying to settle out all dust. Roll up the blinds out of the way when done. My opinion and experience is explosion proof is not needed if the blower pushes the air out, and pulls fresh air in. I cant vent in the winter so the air recircs and I spray wb.

Does anyone know which squirrel fan or centrifugal blower as I see it more commonly called that will work for this and not buy the most expensive one?

Patrick, in addition to all the previous, excellent suggestions, I found that I liked having a lot of tables in the finishing room to spread out the pieces before and after finishing them. I frequently sprayed before gluing.

Patrick go to my LJ workshop page, there are a few pics. I use small plastic clamps to hold the corners together. I can take more detailed pics but it will be a week – Im traveling this week. I use 2”x2” 8 ft long hung from the ceiling to hang sprayed pieces on in the booth – use heavy clothes hangers cut up and little eye screws into the project to hang. A 2×4 is dropped lengthways from the ceiling, mounted with steel corner brackets, with a rotating hook, located close to the blower, to hang pieced while spraying. Also a large and small lazy susan to set stuff on to spray.

Perfect I’ll check that out. I have sheeting and lumber, could you find a fan similar to the one you use?

Having painted a number of cars, if you are building a room, try to get a “downdraft” airflow. It will minimize any stray bits getting into your finish.
