    Default Re: Humidity while painting

    Well, no photos today... seems this was not the day to lay down paint due to several things, but mostly one thing:
    Operator error...
    I have been very meticulous about cleaning the gun to the extent of taking the air cap and needle valve out and soaking in solvent in between spraying times. That being said, I got things set up to spray today, did my test spray on cardboard and went to the wing. The spray pattern started then stopped within 15 seconds (nuthin but air). I went back to the bench, took the gun appart and cleaned it inside and out. Found out that the screen filter in the bottom of the cup can clog up with gunk even though it looks clean from up top. Cleaned it out good and was sure that was it. Put the paint back in, went to paint, same thing. I finally found that the little air hole in the lid of the cup was clogged. After that, the gun shot fine on the cardboard. By this time I was close to the end of my rope.

    The humidity was only 50% and Temp. was a nice 70 degrees. I figured I was in a safety envelope but I still crashed and burned. When I went to spraying, I was introduced to two things I have read about but never met personally... As soon as I sprayed I got orange peel and fish-eye at the same time. I may have had the pressure turned down a bit too much and that probably gave me the OP. The fish-eye is what surprised me because I wiped down the surface with the 2210 prep solvent. I also have an in-line filter right at the gun. I may need to replace my filter and perhaps my hose...at any rate I'm offically calling it a day. Time to go to a movie with the wife.
    Cheers
