Thinking about painting my next project car, and came across a YouTube video where the OP built a makeshift booth in what appeared to be his garage.
Fast forwarding to later videos when he brought the car into the sun, it turned out fairly well, minus some errors that looked like they were probably from his technique.
So, I turn to the experts and ask: What's involved in creating a home paint booth? Assuming small to moderate budget. Is it even necessary? Is the overall goal to eliminate dust and fumes from the area, and contain paint? From research, here's what I've seen so far:
An area big enough for the vehicle and the painter to comfortably walk around the vehicle, and reach the top of the vehicle to paint. This probably goes without saying, but we have to start somewhere. In the video I saw the OP just framed an area with 2x4's and other basic lumber.
A dust free area. I know from vocational school dust and car paint don't mix. In the video, the booth frame was covered with painter's plastic, and held down to the studs and floor with staples and spray adhesive, it seemed to do the job. I would probably use the automotive painter's plastic, where the paint sticks to one side.
Adequate ventilation/Negative Air Pressure. I figured that ventilation would be so that fumes wouldn't build up in the booth, but I'm not sure about the Negative Air Pressure that I've seen used in a couple of videos. In the video referenced above, the OP used a negative air pressure machine, in another video I saw the OP just stuck a fan in the Window, which served the same purpose.
Air filtration. I have to assume that if a fan or neg. air pressure system is blowing air out of the booth while one is working, then that air should (must?) be filtered to remove the isocyanates. The incoming air should be filtered as well to remove any potential dust, correct? How would one filter out the isocyanates from outgoing air? Is it enough to use HEPA 10 furnace filter? Somehow I don't think so. I've only seen isocyanate filters in a small size, to fit in face masks. Do they make them any bigger? If not, one would have to fashion a decent size frame to hold multiple cartridges, a big enough size to match the air flow of volume of air being pulled out of the booth.
This didn't include tools such as an air compressor, sprayer, positive pressure face mask, etc. just the booth,
