basskillr Posted April 1, 2008 Report Share Posted April 1, 2008 Has anyone figured out a way to dry powder paint if there is a little moisture problem with it? I have a new jar of powder that seems to have a little moisture issue and I thought I might try to solve the problem instead of sending it back. I thought about spreading it out on paper plates and cooking in my curing oven at low temp. to see if that helped. Any suggestions? Quote Link to comment Share on other sites More sharing options...
rhahn427 Posted April 1, 2008 Report Share Posted April 1, 2008 I've never had the problem but I think I would put some in a small coffee grinder and use that to break it up alittle then put it in a fluid bed in a dry area for awhile ........ that should take the moisture out ........ I'd be very careful about drying with heat ...... remember this stuff is just a dry paint that melts into liquid paint with heat ....... a low heat may take a long time and just a little too much could cause a real mess ........ Just a thought Quote Link to comment Share on other sites More sharing options...
LedHed Posted April 1, 2008 Report Share Posted April 1, 2008 If you have access, try nitrogen in your fluid bed with the problematic paint. You might also try using small desiccant packets. Might want to contact the vendor - they might send you some new stuff. Quote Link to comment Share on other sites More sharing options...

fish devil Posted April 2, 2008 Report Share Posted April 2, 2008 I have not tried this but you can try putting your powder paint in an air tight container with damp rid. You can get damp rid in home depot. Quote Link to comment Share on other sites More sharing options...
black_co Posted April 3, 2008 Report Share Posted April 3, 2008 You could try one of those silicate bead packets, you know the little "do not eat" packets that look like salt packs. They are in all kinds of stuff that moisture will hurt. Find one and stick it in there and see what happens... Quote Link to comment Share on other sites More sharing options...
soccerer Posted April 3, 2008 Report Share Posted April 3, 2008 I don't know if it would work with powder paint but how about putting some dry rice in the powder to remove the moisture. This is used to keep your table salt flowing freely. Try a small batch first. Quote Link to comment Share on other sites More sharing options...
basskillr Posted April 7, 2008 Author Report Share Posted April 7, 2008 I finally got the problem taken care of. I used a chemical dessicant similar to the little silica bead packs and put it in the container with the paint. After about four days it began to flow better. Another thing I was wondering about with the fluid bed was moisture buildup though time. I do a lot of laquer work in my carpentry business and I have to run a water filter on my compressor to keep moisture out because any compressed air will build up moisture. I always return my powder paint to the original container and seal it after using it in the fluid bed, but how many times can I run a batch of paint through the fluid bed before it starts to have a moisture problem? The answer to my question may be in the porous disc in my fluid bed. It sure seems to be the same material as the insert in the water filter I use on my construction compressor. Any thoughts?
