Question about HVLP 2 DeVILBISS StartingLine Topcoat-Primer SPRAY GUNS
Orange peel can be a really hard problem to diagnose. There are a number of things that can affect the spray pattern. I would start by doing some test spraying. Your air pressure is going to be a factor as well as the ration knobs on the gun. I would start by increasing the air pressure to the gun. Keep in mind that if you're regulator is at the tank the actual pressure at the gun is going to change based on the length of hose used. Generally speaking, more air pressure will disperse the fluids better, better dispersal better/smoother coverage. I'd start there and then tune on the knobs to adjust it. Keep playing with it until you get a pattern you're happy with. Then when you're done with that write down how many turns on each knob, and exact pressure, length of hose etc. This way when you clean the gun you can get it exactly the way you want it. Different products will also spray differently. You may need to adjust for each step in the painting process. I just had to go through this on my new gun and it took about an hour and a pint of clear to get it spraying well. Check out tcpglobal.com for paint and supplies. They have great prices and they also have a forum on painting. I am a user of their products and forum.
