downdraft seems to work best. the big stuff is slightly positive pressure and good air flow
Hey good post NFT5. But alas I am not planning on a paint booth as good looking as yours. I want to try something that I have not really seen before. I’m going to focus my faith in some characteristics and disregard others.
Fan won’t be powerful but it will be close to the vehicle. A hose and mop will be very handy. And the plastic sheeting will be air tight and open at the top of the high ceiling for 2 feet.
If I get too much dust I’ll install filters covering the open part of the booth.
If I still get dust I’ll start using an anti static air gun (some dealerships use them).
Then by that point if I’m not getting better results than the average paint booth than that’s the way it’s going to be.
The confidence that I do have stems from how I can paint a complete car in my small 1 car mechanic shop with 0 dust on side panels and only a slightly alarming amount of dust on hoods.my first paint booth i built was made of the heavy silver tarps and i attached the shop lighting to the tarps and hung them down from the ceiling. i also had 3-4 box fans set at medium speed at one end of the booth up in the ceiling facing down towards the ground and put the tacky 20×20 filters on them. at the other end i had 2 box fans at high speed with regular furnace filters on them for exhaust. it wasn’t ideal but i did paint quite a few cars there with decent results. i have realized that after having a completely framed in booth with seals, doors, etc, it seems it takes a lot lot less time to prep the booth for a paint job. seemed like before it was sweep, blow down the tarp walls, hose down the place, blow it down again, hose down again just to get a decent job. having a clean workspace is critical for getting clean paint jobs and even in my downdraft booth at work i can slack on that and get dust. the 2nd booth i have at my personal shop i built with a squirrel fan intake at the ceiling and a large fan ducted down to suck from the low part of the floor all along the other booth edge. it is framed in with plywood and quad-fold doors. it was probably 2000 worth of materials and lighting but definitely not portable. i did do some work out of a small shop for a couple years and made 2×2 walls that were hinged at the ceiling with plastic sheeting and i would winch them up when i wasn’t painting. that might be a good bet to try since it didn’t take much time to disassemble the booth between paint jobs
