my booth is in the upstairs portion of a 3000 square foot warehouse. it’s an old paint booth built with 2x4s and plastic sheets. I knew I had to had add extra ventilation after the first time a glassed. I’m on a very low budget. So 4 boards ago I added a bathroom fan and ducted it out the roof. The booth is also next to the hatch to the roof, so I propped up a 3 foot fan to blow out the roof. It still gets pretty stinky in any part of the warehouse while glassing, and if I don’t leave the fans on for an hour or so after it will stink the next morning too. I don’t really want to use epoxy either
My current plan is to remount the fan down low in the booth (now that I figured out the fumes sink) and install a 400cfm duct booster in line with the current duct. The smell outside isn’t so much the problem, just don’t want to sit around for it to air out after each time I use resin. And tips that aren’t too expensive?
