I am looking to start doing my own finish work, but have been turned off by the codes required for a booth in my shop. If you spray all waterborne, does that eliminate the need to follow all those strict codes and fire laws? I understand that you still need the required CFM draw to evacuate overspray and fumes out of the booth, but would I still have to have all the clearances, suppression systems, class 1 lights, and explosion proof fans?
From contributor J:
It doesn't seem to me that you would need fire suppression and such, as waterborne is non-flammable. However, if you want the most useful and accurate answer, you'll want to talk with your local officials. What works for someone somewhere else won't mean a hill of beans to you, especially if you get shut down for violating codes.
You can check with the manufacturer or the MSDS sheets for the materials you are spraying to see if the material is flammable or combustible in either the liquid (as sprayed) or dried state (deposits and residues). There are paints that contain no solvent, but the dried overspray can still present a fire hazard.
I couldn抰 agree more with contributor J - it is always best to meet with your local authority (fire marshal, building inspector, insurance carrier, etc.) to determine the requirements for the installation and operation of a paint spray booth.
