Mini paint booth setup?

[jwin615]

For us neanderthals still using rattle cans and clear coats...
I can paint in my basement year round but my method of painting inside of a computer monitor box and quickly shutting the lid isn't really cutting it.
Does anyone have a mini paint booth setup they would care to share? I'm looking coble something together. Need the two fold benefit of reduced dust and fume extraction/reduction. Don't really want to plumb it outside. Just catch it in a filter medium. The ability to store it broken down would also be beneficial.

I've looked at the AliBezos offerings but nothing really seemed great for the price. The airbrush booths mostly looked too cramped for rattle can and I don't have room for a bounce house booth. I need more of a tabletop solution.
So, thinking diy may be best. LPondered a few things like using MERV 8-11 filters as the walls, then maybe both filters supply and return fans, filtered as well.
Curious if anyone else has gone down this path and where they settled.

I think @jjjimi84 has a basement setup, but that might be mostly an airbrush rig.

I’ve thought about it. I’d certainly love to be able to paint year-round, but the only way I think makes sense for me would be to exhaust to the outside. My basement is also my workshop/ music space/ work from home office, so I really spend most of my life down there, and I really don’t like filling the air with toxic crap. I don’t want to spend my work day getting a headache from fumes. Filters are great for catching particulate overspray, but they don’t help you out any with the solvents and propellants.

I got as far as looking at explosion rated inline fans and flexible ducting to run out a window, but in the end I really didn’t want to dedicate the space. I also don’t know if it would work well enough to make me happy spraying inside. Even when I’ve brought freshly painted enclosures inside for the paint to cure the smell bugs me sometimes.

Those inline fans can be found pretty reasonable though. If you’re looking to upgrade your hood from cardboard, I’ve seen some cool stuff made out of the Coroplast material they make some political signs out of. There’s about to be a lot of that heading into dumpsters.

I will take some photos when I get home but my set up is all about fume extraction.

I took a thin piece of plywood, cut an 6” circle in it and attached an adjustable in line fan that blows right into a carbon filter.

When i spray, I shoot towards a furnace filter with the fan extracting behind it.

Works pretty good, I can air brush with no issues and can clear coat about ten pedals without stinking out the family. This is all in an open basement where the smell travels quick, in a smaller set up I think it would keep up really well.

I can link the parts, I think I grab some off of amazon

Yeah! All about fume extraction.


I picked up a "portable paint-booth" from Princess Auto for dirt-cheap...

... basically a pup-tent with no fume extraction. So we use it as a shade-shelter for our pup at car-shows.

Here it is taken apart. Hole cut for inline fan, exhausts out to black carbon filter. Rheostat next to Jimis head to control the speed.


With the cheap furnace filters absorbing the brunt of paint particles.

Here is a side view with the big tank filter and the fan.

I've done a start up on a few large commercial paint booths.

My suggestions:

The best idea here is to exhaust the excess paint and fumes to the outdoors. Nothing about spray paint is good for ya. But you also don't want big paint particles going into your exhaust either, as it can build up and fuck up your fan/become a fire hazard.

That said, if you're doing that you're going to need a supply of makeup air. And that makeup air needs to be relatively clean, else you'll get dust in your paint job.

So that means ideally you'll want filtration on both sides of what you're doing.

Here's what I would do:

Grab some 20mmx20mm aluminum extrusion.

Make a box of sufficient size for what you're working on.

Use plywood on the bottom, make a rotatable jig that pokes through that you can hold the enclosure with (could be simple, say, a slim piece of hardboard that you sandwich in between the enclosure and lid. Drill a through the plywood, attach the hardboard to a dowel, bingo, you're done.)

Put hinges on top so the top opens up. Use plexiglass to make a window so you can see what you're doing.

On the back, make a port for your exhaust fan. Use aquarium filter media to filter the exhaust. Directly opposite that exhaust port on the front use more aquarium filter media to make an "inlet" filter with more aquarium filter media.

Last step, do the glove box thing. Fill in the remaining sides with hardboard or plywood or plexiglass, cut a hole, grab some hardware for mounting a glove for your can...eh...hand.

Also compatible with paint guns, just need to add another semi-sealed port for the compressed air line. Probably could be done for somewhere around $250 including a small exhaust fan.

Might be overkill, too. Room filtration, a protective tent like enclosure, and a respirator might do the trick well enough.
