dwc43 Posted October 2, 2009 Posted October 2, 2009 What do you guys do about the humidity ?? It's been raining here for almost 5 or 6 weeks straight. I have this perfect semi gloss black paint that always works flawlessly, until it rains. It gets the ghosty white look to it. I need to paint some stuff and sure enough, it starts raining again today and probably will last through the weekend, again.
Foxer Posted October 2, 2009 Posted October 2, 2009 I have my paint booth in the basement and it IS very humid down there without the a dehumidifier running all year round. At least it does take care of the paint problem from it.

DW the white haze is caused by the moisture condensing on the paint as the solvents flash out of the lacquer. The only solution other than removing the humidity is to find the slowest drying thinner you can or by adding a retarder to the paint. I used to get both from my local auto paint supplier. Another thing I have done is paint out in the sun but if it's raining I guess you couldn't do that either Hope this helps ya.
Guest arni Posted October 2, 2009 Posted October 2, 2009 I find this an interesting subject re temperature/humidity regards spraying. To set the plot,Belfast is aprox 700 miles further north than New York yet due to the gulf stream we get mild weather. The temperature right now 10.30pm my time is 13 deg C/55 deg F.The humidity is 82% and I have never had problems spraying here. The max temp in summer here is if we are lucky..27 deg C.Not joking here,that is a good day. I would like to know how this relates to your spray jobs.

E St. Kruiser50 Posted October 2, 2009 Posted October 2, 2009 (edited) FUNNY YOU SHOULD ASK I have a walk in heated spray booth, that I'm using as we speak. I just finished spraying a project @80 degrees. 59 degrees outside and raining. I've read here where the guys with the same problem as you, put their model in a pre-warmed food dehydrator, and that helps get rid of the moisture and blushing. Also, don't forget that pre-warming the can of paint helps a lot too. Edited October 2, 2009 by Treehugger Dave
935k3 Posted October 3, 2009 Posted October 3, 2009 Get a dehydrator and put the painted part in it as fast as possible.
dwc43 Posted October 3, 2009 Author Posted October 3, 2009 Thanks for the ideas. I forgot about warming the paint trick. I might give that a shot if I get to paint this weekend.
Lownslow Posted October 3, 2009 Posted October 3, 2009 i got a heater that takes care of humidity, warming the paint does help a lot so does slow drying thinner
cruz Posted October 3, 2009 Posted October 3, 2009 I have never had any issues with humidity here in Maryland but I never take any chances either. What I do is go to Wal-Mart or Home Depot and get me some Damp Rid, it absorbs humidity in the air. I don't like to explain much, that's the reason I invested in a digital camera and computer, the pictures will say it all! What I do is open one at least 3 hours before painting and I am ready to go!!!

I have a separate storage building where I keep my Road Runner show car and we keep some of that stuff in there. Works pretty good too. Just never thought about using it indoors where I paint though. That's a good idea.
Harry P. Posted October 3, 2009 Posted October 3, 2009 What do you guys do about the humidity ?? You might consider moving to Arizona! But seriously, though, why not try a paint that isn't affected by humidity, like acrylics?
