Materials required
1 car Part of my 3 car garage.
20" box fan or some other kind of fan(s) to keep the air moving preventing dust from settling.
Enough poly sheeting to cover walls, garage door, and whatever else you don't want over spray on.
Tape poly sheeting to the walls and/or hang from the ceiling, garage door, and anything else you don't want over spray landing on. For me this also partitions off the area of the garage where the rest of my shop is so dust does not migrate in.
Open the garage door and wet down the garage floor with the garden hose to keep any existing dust down. If the floor is very dirty or dusty, you may want to mop or give it a thorough cleaning first.
close the garage door so it's open about a foot or so.
place the box fan on the end of the garage opposite the garage door and turn it to its lowest setting. You don't want a wind tunnel, you just want to keep the air moving so dust does not settle.
place your project to be sprayed up off the floor, remember the floor is wet.
Do your spraying and let everything dry.
Keep in place and possibly re-wet floor (you can damp mop rather than running in the garden hose)
When finished with your spray booth, put away the fan, take down the poly and store it away for future use.
Clever positioning of the poly can alter the size of your booth as well.
I don't put poly sheeting on the floor as I don't like the walking on ice feeling.
You also have the fixings for a fairly impressive explosion.
Think about it air laden with extremely flammable vapor being drawn into the fan that has open switches that can spark and set off the explosion.
If you are going to use a fan to draw air out of your paint box go find an explosion proof fan. (switches are sealed as is the fan motor itself).
Even if you don't have an explosion you can also draw enough paint into the fan motor to coat the armature and make it run extremely hot.
One last thing and I speak from experience make sure you know where the exhaust air is going. I once painted something red and when I finished I noticed the side of my neighbors house was an interesting shade of pink. Thankfully by the time the paint made it to his house it was dry and all that was actually on the house was a red dust coating which washed off with the hose.
I had visions of paying to reside this house.
Also I have a black truck that has some white dots on it. I won't go into how but let me say I now have a filter on my exhaust fan.
