markw Posted November 9, 2010 Report Share Posted November 9, 2010 Even though it's an amazing 69 degrees in Minnesota today, I know reality will set in soon. I just started playing with powder paint and and do my painting/spraying in an unheated garage. I know I may struggle with keeping things a good temp when attempting multiple color combos, but I was curious if there may be other paint quality issues that arise in cold temps? I've seen picture of people spraying into a box without over spray problems. I think it it looks like TJ Tackle did their powder spraying videos in a kitchen. Unfortunately that isn't really an option for me. My wife isn't gone nearly enough Quote Link to comment Share on other sites More sharing options...
smalljaw Posted November 9, 2010 Report Share Posted November 9, 2010 Actually your better off in cooler temps, for me its always more difficult to use powder during the summer months because the high humidity makes the paint want to clump together.

Fatman Posted November 10, 2010 Report Share Posted November 10, 2010 Don't see any problem with getting them heated and coated BUT when you're done I don't think you should leave your raw powder out in yoour garage it could clump up or harder with any moisture changes.

Fatman The only issue with powder painting in an unheated garage is if it is extremely cold and you allow your spoons to cool too quickly. I started powder coating trolling spoons a number of years ago and had issues with the finish getting small cracks and crazing when I quickly heated a spoon with a torch, sprayed it with the powder and just set it on the cold workbench to cool. Now I use an electric frypan that my wife can't find to preheat the spoons and post powder-coat cure. When there is no room left on the pan for more spoons, I'll turn it off which gives them a chance to cool for a more prolonged period. I still bake 'em in a toaster oven for the final cure period, but again, there is a longer cooling period involved. I keep my powder in Glad plastic containers with the screw on tops, keeps it dry regardless of where I store them. I place a dessicant canister in the container to address any moisture issues for good measure. Quote Link to comment Share on other sites More sharing options...
