No matter how experienced the sprayer, merely triggering and moving a gun in space will not reveal any of the performance characteristics vital to a top quality finish. A simple brief static spray pattern will immediately highlight any potential problems before the gun is used on the painstakingly prepared workpiece or vehicle.
Follow the procedure explained below and compare the pattern to our examples. If your result resembles examples 2-8, then look at the corrective measures before you apply paint to the workpiece.
1. Ensure that you have the correct air cap, fluid tip and needle set-up on the gun to match the material being applied.
2. Tape up a piece of brown paper – approx. 20” (1/2m) square – onto the spray booth wall at shoulder height.
3. Having set the gun at the recommended inlet or atomizing air pressure, hold it at the correct target distance and spray at the paper WITHOUT MOVING THE GUN.
