Great idea! Its good that the installed the air inlet higher up in the wall... But you might get better results if you install the exhaust as low as you can in the wall... you want to pull the fumes and overspray across the booth and keep it low in order to keep as much of the dust down towards the ground. Then wet your floor to help catch some of it... I had a cross draft booth and found out after a few jobs that i needed to move my exhaust side down low to the ground... After doing that, it helped with cleaner paint jobs...
You want to make sure your extraction fan& lighting are all explosion proof. One spark from them with a gazebo full of paint fumes won't end well. That's why commercial booths have enclosed lighting a explosion proof extraction fans. Good luck with your project.
I have now built two different paint booths. The first was a portable garage set in the yard, the inlet side had furnace filters up high and the outlet side at the other end had a couple box fans. I spent days sealing it up and I still had dust issues. The issue is if you're sucking the air out, you have a negative pressure in the booth. Any air being sucked in through any cracks will bring dust/bugs in with it. You also have a possible ignition source in the fan as your fumes come through. My second one, I set up a plastic booth inside an actual garage. My inlet side I had furnace filters up high, but had 6 box fans set on low that blew fresh air through the filters. At the other end of the garage I had looser packed furnace filters down low. This worked out much better, as the air coming in to the booth was filtered and creating positive pressure inside and the air was blowing out through any leaks, no dust could get in. The reason for so many fans was to create more volume of air with less velocity to avoid messing up with painting. With the fans upstream and out of the booth, they are no longer an ignition source.
Didn't need a exhaust port at all. If the blower is blowing air into the booth you created a positive pressure plenum. What you want is the exhaust air to leak at the concrete level this way no dust or debri can back track against the air flow. Now you have a down draft laminar flow booth....Mount the air blower as high as possible...
That's a pretty neat booth you have made yourself. I have been thinking about making a spray booth myself and will probably go with something I can string up from the rafters with some pulleys so I can have it up out of the way when not in use.
+8700s14 If you have the roof height, then this would probably work for you as it is light. You will need to tape the poles together so they don't fall apart when you lift it up.
Wow! Great booth and ventilation man! Wondering if outdoor LED strips would be a better route for the lighting in there. Two strips for about $20USD and a few more for the power plug and remote.
Don't get discouraged. In the old days, my father used to smoke while painting. The whole explosion thing is overrated as it simply won't happen as the mix of air and flammable fumes is just way off to get ignited by a motor brush spark. Also, fluro starters do not spark so that is nonsense as well.
I was thinking that while watching your video, not for safety but just because the LEDs are a far better light source than the floors... can't beat switching over to LED.
Not being hysterical but see my previous reply to another comment. I've seen open air spray booths go up in a shop front/cabinet making business simply by spray fumes entering the exhaust fan and being ignited by the tiniest of arcs through the fan (later found to be the cause of ignition). It does happen and that was in an open air booth. It spread so fast given all of the combustibles, mdf, paint, dust particles, etc etc. Nobody got hurt but the factory was completely destroyed and impossible to stop. Not trying to be a nanny, I'm a qualified sparky and just trying to spread the awareness. It happens in professional industry which is apparently safe and regulated so don't think it won't happen to Joe blow at home (more likely in my opinion).
Nice work! I'm thinking of building one in my garden as the climate is suitable where I live. My concern is my neighbours and how far the odour travels from the booth. I'm guessing that will be a show stopper for me.. can you pls tell me how far (very roughly) the odour would travel from yours when spraying, assuming your garage door is open.. thanks!
Actually I kept the garage door closed when I sprayed but the flexible tube from the fan went out the back window of the booth. The garage did smell pretty bad, but outside it was not very noticeable. If you can seal the booth really well, you could probably run the tube from the fan up into a tree or something to get the smell up and away.
All depends on airflow that particular day, you can't really judge but yes it can be an issue with neighbors. I have the same problem painting in my garage.
Jeff, thanks for posting this interesting project. I'm in the process of designing/building a spray booth, more for furniture and various metal work projects than a car. I'm converting an old travel trailer. I have a question - do you know whether the fumes from any particular solvent/paint are lighter or heavier than air? This would influence how high up in the wall you would situate the extraction fan. How did you decide where to place the extraction fan in the wall?
I actually didn't put a lot of thought into it, beyond not wanting to stir up the dust on the floor. Ultimately I think the overspray is generally heavier than air as it is just paint droplets, but I am not sure about the fumes.
If you haven't seen it yet, look at my second spray booth videos for improvements. But my best suggestion, if you only have the one fan, is to use it to blow into the booth and just have some filter material at the opposite end where the air can go out. Positive pressure is much better all around.
I got the paint booth filter material in a roll off of ebay. I can't remember exactly what it cost me off the top of my head, but I got heaps and it wasn't very expensive.
Yes I used a 3x6 gazebo which would work well for small cars. If you have bigger cars you may want to look at joining 2 together or finding a slightly larger one.
+Home Built By Jeff hope it is one of Porsches classic but exclusive colors. I like their riviera blue, Mexico blue or slate blue and also slate grey and anthracite grey.
+xkrnxboix It is a classic Porsche colour. Not everyone is going to love it, but I suppose I am building it for myself, and it is what I have always loved.
But that would be one in a million chance, far greater chance you'll explode driving down the road in your car LOL. I actually paint with a torpedo heater running. 😅
Home Built By Jeff thank you Jeff! I did the exact same thing. Did you order the black chinese ones or in a roll or something? :-) greetings from Norway.
Go for it. Make sure you look at the second video as well for some important things I didn't do in the first one. With a Mustang you may want to get yourself a bigger gazebo, so you have room to move around the car, but the rest is good.
There are several components to getting a good result. One resource I found which successfully combines these is the Magic Painter Method (check it out on google) without a doubt the most incredible info i've heard of. Check out this unbelievable website.
Dude, building that was a total waste of your time, effort, thought, materials, money, etc. --all you really had to do was paint & clear with the garage door open then close the door when done painting...later rookie!
Great idea!

I've been youtubing homemade booth videos for days.
And finally I come across the best idea so far, and from a fellow Aussie . . respect
I totally agree, I have made some mockups that failed using other people's ideas. But I think yours is going to work. Thanks.
Artistic talent and car building/handiness are just unbelievable. Keep posting!
Thanks mate. Glad you are enjoying it.

Have a look at my "how to make a better spray booth" video ;) th-cam.com/video/_aoHCy1meVA/w-d-xo.html
This. Fumes are flammable. If that fan creates any spark it can be bad.

Have a look at part 2, I cover a lot of that there. Positive pressure is a must.

That wire mesh, is called chicken wire here in the States. I'm inspired, thanks for taking the time.
Chicken wire in the UK too

That would probably be a great way to do it. The more light in there the better. Not sure if they would be bright enough, but it would be worth a try.
Just hang plastic in existing shop with clamps. Wet walls and floor before painting.
This is sick. I want to do the same!!
Awesome build! A fan from the middle east!
+Faris Sal Thanks mate, glad you are enjoying it.
I like this idea but I would have the gazebo outdoors and use natural light
You can do that absolutely. Having it inside just helps keep it cleaner.
Well Done ................but put the lights outside unless they are low voltage . ...........
If I ever get marooned on an island; I want you with me!
Don't get discouraged. In the old days, my father used to smoke while painting.

Also, fluro starters do not spark so that is nonsense as well.
I am of a similar opinion, but I have now changed over to sealed LED's anyway so I am not too worried.
I was thinking that while watching your video, not for safety but just because the LEDs are a far better light source than the floors... can't beat switching over to LED.

I just love this channel. Keep it up 👍
And 5 years later he’s ready to paint the car ;)
Jk great set up 😁
great ideas thanks for the videos man =)
Dude I’d kill just to have a garage that size. 99% of the garages where I live are 5m x 2.5m, I’m fucked even wanting to try half of this shit.
instead of plastic on the bottom just wet the floors, keeps floor dust on floor and catches dust in air
+All2skitzd I will be wetting the floor as well, but the plastic is there so I don't get paint over my nice clean garage floor ;)
Nice work! I'm thinking of building one in my garden as the climate is suitable where I live. My concern is my neighbours and how far the odour travels from the booth. I'm guessing that will be a show stopper for me.. can you pls tell me how far (very roughly) the odour would travel from yours when spraying, assuming your garage door is open.. thanks!

nice. same idea i had. just pricing the gazebo's now. Do you have a link to the one you bought?
I don't still have a link, but it was just search ebay for a 3m x 6m gazebo, and get the cheapest nastiest thing you can find ;)
Just buy a 10x20 car canopy with sidewall kit. It cost me $150 for all on eBay
Making quick progress on this
+lukeybabes1 Yeah, I don't want this to be a never ending project. I actually want to drive it :D
Love this
Thanks mate. I hope it is useful.
Brilliant!!
Had the sound off. Fucking knew you'd be an Aussie
Awesome! Any idea what color you are going to use?
+Furious Panda Ahhh. That is the question, but you will just have to keep watching ;)
***** Dont worry, I plan to :)
Thanks for your swift reply
If you had to re do the funnel how would you do it?
Im thinking of using material instead of mdf. ..
If you haven't seen it yet, look at my second spray booth videos for improvements. But my best suggestion, if you only have the one fan, is to use it to blow into the booth and just have some filter material at the opposite end where the air can go out. Positive pressure is much better all around.
why is the extractor faced towards the car more like a regular vent but with a protection to keep whatever from out side to come in.
Watch both videos then ask me any questions...
awesome
Thanks mate. Make sure you check out the second video "How to build a better spray booth too" I have madesome good improvements.
Excellent video , many thanks , am building this weekend.. same fan too, I dont suppose you have the measurements for your fan funnel?
Unfortunately I don't have those measurements, but although it did the job the funnel could have been a lot better.
thanks alot mate
hi mate just wondering what material you used for the filters?
I got the paint booth filter material in a roll off of ebay. I can't remember exactly what it cost me off the top of my head, but I got heaps and it wasn't very expensive.
Great idea! I got a chev....it ain't gunna fit!!
+Darren Morton You could possibly get 2 of them. You would probably need to support the centre where you take out the middle legs, but it could work.
+Home Built By Jeff checking out eBay now!!
+Darren Morton I haven't looked but maybe they even come in a bigger size that will work for you.
is this the 10x10 tent or the 10x20 tent?
What size was the portable gazebo you used in the video? 3x6?
Yes I used a 3x6 gazebo which would work well for small cars. If you have bigger cars you may want to look at joining 2 together or finding a slightly larger one.
Wait... so what color would you be painting the 911?
+xkrnxboix You will just have to keep watching ;)
+Home Built By Jeff hope it is one of Porsches classic but exclusive colors. I like their riviera blue, Mexico blue or slate blue and also slate grey and anthracite grey.
+xkrnxboix It is a classic Porsche colour. Not everyone is going to love it, but I suppose I am building it for myself, and it is what I have always loved.
Awesome. That's all that matters in the end. *Thumbs up*
Pink
why would the lights explode?
The lights themselves would not explode, but their igniters could ignite the flammable paint fumes causing an explosion.
But that would be one in a million chance, far greater chance you'll explode driving down the road in your car LOL. I actually paint with a torpedo heater running. 😅
Where can i Get those filters, and what are they called?
I just did an ebay search for Spray Booth filter, and it comes in a roll.
Home Built By Jeff thank you Jeff! I did the exact same thing. Did you order the black chinese ones or in a roll or something? :-) greetings from Norway.
In a roll.
Is that the 20x30 canopy ?
Did you watch the video? 6m x 3m.....
What size was the gazebo you used?
The gazebo was 3m x 6m, but if you have a bigger car you may want to find something a bit bigger.
Thanks for posting this video. I'm planning to use your idea(s) on my mustang project.
Go for it. Make sure you look at the second video as well for some important things I didn't do in the first one. With a Mustang you may want to get yourself a bigger gazebo, so you have room to move around the car, but the rest is good.
Thanks - I saw the second video as well. You describe you fans as "brushless" motors I believe. Where did you get those?
They are straight off of ebay. If you saw the results of my Porsche, I am very happy with the paint job I did in this booth.
salut je pense que l'autre capot moteur en forme de spoileur pour l'arriere de la porche est plus riche en forme et en loock
Your high speed might be a little high!
I can answer any questions if you need any extra info that I glossed over.
There are several components to getting a good result. One resource I found which successfully combines these is the Magic Painter Method (check it out on google) without a doubt the most incredible info i've heard of. Check out this unbelievable website.
Exhaust fans should be explosion proof or you risk the motor igniting the solvents that will be sucked past it. Booom!
Why don't you buy a BMW x6 instead of Mercedes Benz
like
Completely unsafe, your booth should be a positive pressure booth. Air should be forced in not sucked out so you don't blow yourself up.
...watch part 2.
Dude, building that was a total waste of your time, effort, thought, materials, money, etc. --all you really had to do was paint & clear with the garage door open then close the door when done painting...later rookie!
Haha. It is not my first rodeo.
