It’s cold outside so those of us who have cars to build need to paint indoors. Here are some pictures of a simple portable spray booth I put together that helps to keep the air fresher in my home. It was made using a clear polypropylene tote that I got on sale from Canadian Tire. This material is fairly easy to cleanup after painting and it allows in outside light for greater visibility.
It uses a box in box design that allows for perfect sealing and easier portability.
It uses an equipment rack fan that I bought on Amazon for just over 20 bucks. This fan runs on house voltage, is brushless and sparkproof and moves 110 cfm of air.
this type of fan allows you to use any normal hobby paint including nail polish and automotive lacquers.
The filter consists of lighting grid cut to fit and fine aquarium floss built into a dollar store food saver. The fan is bolted through both boxes and the exhaust fitting making for a leakproof seal. I also added an on/off switch for convenience.
The exhaust uses 4″ semi flexible metal tubing attached to a woodworking exhaust fitting at one end using a 4″ hose clamp and a dryer vent quick connect at the other.
This is attached to the other half of the quick connect that I have bolted to a wooden window insert.
As the main box was originally a tote the hose clamp can be loosened and the entire exhaust be put inside ready to be moved.
My wife was painting a C4 corvette for Group 25 that Ken kindly gave her so we had a chance to test out the design. It worked flawlessly.
It’s best to start the fan before painting and to leave it on for a few minutes after you finish to make sure no solvents escape back into your home. Please remember that you should also be using appropriate safety equipment for the type of finish you’re spraying. As I tend to use lacquers that means a respirator , gloves and eye protection. The whole project went together for about $75.00 worth of materials.
I hope some of you find this useful. Let’s get building!
Cheers
