How long after priming and/or painting with spray paint does the paint need to "cure" before being exposed to cold temps? The issue is my wife has a nose like a bloodhound (sensitivity wise, not appearance wise:wink, and has informed me there will no more paint smells coming in from the garage. After 39+ years of marriage, I totally agreed. What I would like to do is set up a small paint booth (cardboard box and large trash bag) heated with a small space heater in a small shed in the backyard, but I don't want to leave the space heater on too long unattended. I would like to do my priming/painting, leaving the heat on for a couple hours, but then let the rocket set for a couple days before bringing back inside the house. Will exposure to cold temps hurt the primer/paint if kept heated for a couple hours after painting? If not, how cold is too cold? I am using Krylon primer and paints 99% of the time. The night time temps have been avg. around 30 degrees F.
