66 30 psi 35 psi 40 psi 45 psi DETERMINING THE CORRECT PRESSURE WITH YOUR GUN AND YOUR PAINT • Hold the gun about 6-8 inches from a piece of masking paper. • Set the pressure at 30 psi, pull the trigger back fully and release. • Repeat at 5 psi increments until two identical patterns are produced. No single spray gun or setup will work for the entire project. Don't adjust the paint so that the equipment works properly. The equipment should work as you need it to. If the result is not satisfactory, change equipment and/or equipment settings to improve results. When in doubt about spray equipment, ask the spray equipment manufacturer or your PPG Distributor for assistance. In this example, the optimum pressure will be 40 psi. For HVLP guns, air cap pressure must not exceed 10 psi to meet air quality regulations.
