A question about spray booths...

Greetings all,

I just built another foamboard airplane and I am going to do some crazy graphics on it just for practice. I am doing all of my painting at my dining room table and I am wondering about how much overspray I am going to deal with.

I really don't have enough room to build a spray booth so what other options do I have or do I really need one for these small projects? Thanks!
 
You could make a small booth/ box out of PVC pipe and plastic sheeting (sized to suit your table so your not restricted by size layer) it’s easy to dismantle as needed. I’ve done it large scale in my back room, I’m in a rental so I’ve essentially built a room (PVC pipe and plastic sheeting) in a room so I don’t have to repaint when I leave.
I don’t do high pressure spraying in there so it’s probably not needed but better to have and not need than face palm at the rainbow paint work when I leave lol

That sounds like a good idea. I didn't think about the pressure I would be using but it probably will not be over 20 lbs. or less. I have never seen any overspray floating around and my wife has never said anything about paint fumes and she is normally sitting about 15 feet away.

I've done something very similar to this using aluminium tube from an old marketing display stand. Very quick to put up and take down as required.
 
I've seen Alex @Ttxela use a diy booth in his kitchen/dining room, he has it on the table. I'm sure when he see's this he will be able to tell you about it.


Ha, cross posted with you there - yes I have a video of making it somewhere but essentially just knock something up with whatever you have to hand. I just happened to have aluminium tube.

The only thing to consider perhaps is that it doesn't provide any ventilation. I find it Ok for detailed airbrush work where the amounts used are minimal, if doing larger areas or spraying base/clear I run the kitchen extract and wear a respirator.
 
Well considering that I am using very low pressure and I am not spraying large areas or items, I still wonder if I need something to collect the minimal overspray. I do not have any way to vent the air outside for one thing and that could be a big issue. I am only using acrylic paint also.
 
At the psi you are spraying at, the over spray will be minimal. A fan blowing air across the area will at least help keep it from gathering on the table. I have been painting in a small room (large closet) thus far and have not had any issues. It won't protect your lungs, but the furniture should be safe.

Thanks Karl. The table is protected by a cheap plastic tablecloth just for that reason. With just the spraying I have done since last year, there was hardly any overspray dust on the tablecloth when I wiped it down a couple of weeks ago. As far as what I could breathe in, not a problem with my new RZ mask. :)

A fan drawing through a filter behind the workpiece might be a solution. I have a fan and some filter material I'm considering adding to my set-up.

That is a very good idea! I built something like that years ago to collect wood dust while sanding at my workbench. I am sure I can replicate it easily. :thumbsup:
 
I can't afford anything like those but what I have in mind is cheap. The one I built years ago for m workbench was just a cheap 20" box fan with a 20" high density filter attached to the front and back. It was very efficient on the low speed setting. The best part is that I can buy the parts locally.

if you press on each on those paint booth I provided link, you get picture of measurements for the build of that paint booth.
 
How good are you at making stuff?
Years ago I made a thin 3" deep box frame with a raised bit in the middle. A fan behind sucking air through a hole in the back which had filter material in it. Any overspray went to the sides and got sucked through the hole at the back into the filter material..

Its only for panels due to the depth but they work quite well.

I just put this together to show you how it works.

Might be helpful to someone.

That is a great idea and design and yes, I love to fabricate things. I have saved the illustration so I can build one when I get to painting on flat media. I might just build one that has some short legs on the back so I can lay it flat and lay the plane parts on it like a downdraft table. I like the airflow design on this. I could see laying in filter material everywhere on the inside to catch the particles. Thanks for sharing that idea and for the pictures! :D :thumbsup:
 
Here's my favorite resource for DIY spraybooth building:
http://www.modelersite.com/Abr2003/english/Spray-booth-design_Eng.htm

I like that site specifically because, unlike most, he actually did the for realsies engineering, and provides the maths in an easy to use form so you can adapt it to your own situation and materials.

Most online tutorials are written by people who just slap a computer or bathroom fan in a box and assume it's good simply because it turns on. They don't actually know any more than you, they just did their bodging together first and posted it online.

Particles and vapors from an airbrush aren't always strongly detectable to the human nose. It's easy to have concentrations that are unhealthy, but don't smell like hardly anything, so actually doing the math is the only way to know you're not building a space-wasting placebo.

Now that certainly reads like the fella knows his stuff. I've saved that for reference when building mine.
