Started out with a HVLP gun but couldn't get it to spray so I went back to my sypthon gun. How do you set up a HVLP gun. Instructions said 29 psi in gave 10 psi out. It just blobbed out paint.

Don't know the CFMs but It will let you run a DA sander all day long, without running out of air. I figured the reducer was part of the problem Instructions for gun were extremely vague.

Finally found out that if you run 40/45 going in it will flow good. I also use 3 inline drier's and a gauge on the gun. Might back down on the reducer to 1/2 and use a fast reducer to keep runs down.   [Reply]  [No Email]

You are supposed to use what it says on the gun, or in the info that comes with the gun. There is no need for experimentation, provided it is a quality gun, and in the case of urethane follow the paint instructions exactly. I have never had a problem with one unless it was my fault, not the guns. Cheaper paints such as alkyd enamel are less clear on the ratio.   [Reply]  [No Email]

If your dealer can't supply the tech sheet (he should) you can find it on PPG's web site. A slow reducer is for temp above about 80 if I remember right. But it really doesn't make much difference if the temp is at least 70. HVLP guns work best with the paint flow adjustment set wide open, same with the pattern. The 29 psi is set according to a gauge you should have on the gun. If you do not have a gauge on the gun, the reading, wherever it is will be wrong because it does not take into consideration the length of the hose you are using. You obviously have something not adjusted right. I've been using HVLP and PPG Omni for 10 years, not continuously but some every year.   [Reply]  [No Email]

Read the instructions that came with the gun to see if they list the cfm's needed from your compressor. I couldn't spray a large item using my old compressor with my HVLP gun.
