I decided to get back into model making, so a spray booth is a real necessity. Acrylic paints have improved
immensely since my last foray into the hobby, but you typically thin them with alcohol and distilled water
rather than just water.. primers of the best quality are oil based, so that means paint thinner or lacquer
thinner to spray the paint.
A sealed bathroom fan unit 50 to 70 CFM is perfect for this, along with some good quality furnace filters.
Then it is simply a matter of building a box open on one side and wiring everything up. A 3 inch flex hose
can be routed outside, or to a dryer vent box. add a turntable and a light, and you are good to go..
I thought I would post it here as a lot of folks spray gunstocks and parts....this would also be great for
epoxy coating or sanding.
You can use 1/4 " plywood or melamine for the top, bottom and sides, 2 x 4 s for the frame to hold the fan,
and 1 x 1 stock to frame everything. Caulk the insides, and add some foam weatherstrip to ensure a good seal
around the furnace filter.

A low-rpm power turntable for one of these is a lifesaver when it comes to getting a good cover. I used to do quite a bit of CeraCoat with the Wheeler spray cans. Makes considerable difference in getting an even coat.... Adjustable rpm is the Cadillac....

Just a thought, but a collapsible one would be handy when you don't need such a thing all the time....

I will be building one of those!!! I’m closing off a garage door and adding a yard area for my layout. I’ll put the spray booth under the layout bench work and exhaust it right outside.

The top and sidewalls are screwed together, but you could use dowel plugs and small hinges on the sides to
make a collapsible version. The versions I have seen online are corrugated plastic with little exhaust fans.
I tend to go overkill 9000 on stuff I build..
