Spray Booth

[trackman]

Going to make a spray booth for finishing. Any of you come up with a good way to make one?

I bought 3 cheap shower curtains and hung them about 18" above the floor. Used a 20" fan on the floor  pulling for the 3 sided enclosure under the curtains. Seems to work well controlling the over spray. I have been spraying quite a bit of Aqua Coat clear lacquer. No odor and sprays nice.

I guess first off my question is.. how large of a booth you looking to build? What kind of budget you looking to spend?

Coming from an automotive standpoint I've seen a lot of creative paint booths just built out of plastic sheeting.. .. I've also seen and worked in a one million dollar manufactured booth.. with top of the line ventilation with massive filters to catch the pollutants from going into the air stack, baking oven, lighting.. almost the whole thing was a big light, LOL.. Are you just looking for a spot in your shop where there is no sawdust floating around?    

In the automotive world.. I've seen paint jobs done right out side that turned out better than the in the million dollar booth.. I've seen fibers from clothing fall into a paint job in that booth.. so as for keeping dust etc. out is tricky to do in a place that makes sawdust, LOL.. You could have the best booth in the world.. but if you walk in the booth after scroll sawing to do a little spraying.. well the dust on your clothing just contaminated the booth..

I have a 5'x4' booth in a corner of the shed with a couple of exhaust fans in the wall at the back and a fluro light above.
Works pretty good for painting and polishing, however it could really do with more powerful fans.

You need air movement.. and what I mean by that is.. If you only have exhaust fans the air movement will be minimal... You need a inlet fan on one end and a exhaust on the other end or side wall whatever.. But only having exhaust fans without a source of fresh air intake you're not getting enough air movement.. You also would want your intake air to be filtered clean air..  probably best to have a bigger fan for the exhaust and a smaller one for intake.. this would create a small vacuum type action and would probably be more efficient that having two of the same air flow fans..  Also might help to have inlet down low and exhaust up higher.. or the other way around..  You could get one of those fog machines they use at Halloween time and see what works best for air flow for your type / size / shape of the booth..  Air flow is a funny thing.. with certain sized and shaped rooms.. one corner of the booth could have no air flow and everything gets stuck in that one corner while the flow is good throughout the rest of the room..  experimenting with a fog machine would be a great way to get the best set up for your particular room..

I just need to make something big enough to finish scroll saw projects. Seen one on google using cardboard sides and a 20” fan with furnace filter.  Didn’t know if that would get fumes out an dust     Know people here come up with some good ideas for doing things.

I won't laugh, mine looks exactly the same. I take a bin outside and spray.  Voila !!  That said I usually only spray with a light varnish and only my scrolling stuff.

I bought a little kids tent.  i put it on a table outside and wear my mask and it works great.  I put weights in the corners if its windy.

Here ya go, they come in a few different sizes.

When I worked at Walmart, the meat department had large cardboard boxes, maybe 20 x 30.  I used the for years.

Back in my engineering days (30 yrs ago) One company I was with built makeup air heaters for Macco, prisons, all kinds of places. Those setups were some high dollar ones.

We need a "smirk" icon.

If you are going to have a booth that you can not walk around in, you also need a turntable type thing so the work to be sprayed can be turned easily.

My "spray booth" is anywhere that the wind isn't blowing. Sometimes in my shop, sometimes outside my shop. I can only dream of a "spray booth".

Maybe I should have said Spray Tent lol. Want to be able to spray in shop during winter without gassing myself. Make a “tent “ with a clothes dryer vent to outside.

I get large sheets of cardboard or big boxes from work.  The sheets work great, because I can customize the size of the "booth".  I tape 3 pieces together.  This makes the back and 2 sides.  Taping them together allows me to fold it up for storage.  The back has a hole cut in it and a furnace filter hot glued over it.  I then set another sheet of cardboard on top.

I have a fan in the window with a furnace filter over it.  Then I have another fan behind me, gently pushing the air through the booth and toward the window.

I made a platform, with a lazy Susan turntable on it, so I can spin it around.  This set up works pretty well for small stuff. 

I will say that a proper spray booth is supposed to have explosion proof lights. I don't, but I try to take care to avoid too much overspray fog.

I purchased one of the science fair poster board thingys!  It is three sided and I sit it atop a piece of cardboard.  I make sure the exhaust fan in the adjoining bathroom is running.   That's about it.

Here is pic of my set up. Right hand wall is hinged so it can fold back against the shed wall, I have never done that .
I have a large turntable on the table, which can be removed.

Mine is really high tech. I used the cardboard box that my mitre saw came  in, cut the front & top out of it & put it on the outside bench , I am looking for a new box now as it was left out in a rain storm & is now a bit buckled.

I like John B set up. I can get a bathroom exhaust fan and have it vent into the barn. Should take care of the fumes.

I think it will depend on the size of the objects you want to spray and the available space. My shop is the lower level of a split level house. Some of the projects I do are fairly large. So I attached 1 x 2's to the ceiling and added hooks to that. That way I can hang cheap plastic tarps, cut to size. I have decent LED lights but bring in a 3 unit pole lamp which can be easily directed on a project. I have a standard 20" box fan with 3M filter that goes in the window for exhaust. Depending on what and how much I'm spraying I'll open another window on the opposite side of the basement so more air can move through. When I'm not spray the plastic comes down and gets folded into a box. I have a turntable set-up I can bring in for a project that needs it. It consists of a B&D Workmate as the base (that gets covered with a plastic tarp), a 14" lazy Susan, and a few different size pieces of scrap PW the project can rest on. But here I've hung the Display Shelf from a hook. It turned nicely and allowed me to spray the whole piece. When set-up for spraying it's about 6' x 8'.

I like John B's setup also. When we get back next spring I may try to build something like that.
