What adjustment should be made if a figure 8 pattern appears while spraying?

When a figure 8 pattern appears while spraying, this indicates that the spray pattern is uneven or has an inconsistency in the way the material is being applied. The likely cause of this issue is excessive air pressure that leads to an overly atomized spray, causing separation in the material as it leaves the spray gun.

By cutting down on air adjustment, you help stabilize the spray pattern. This reduction allows the paint to atomize more evenly, resulting in a more uniform application without the disruptive figure 8 pattern. Lowering the air pressure can assist with creating a more controlled flow of material from the spray tip, minimizing the turbulence that can cause such patterns.

While adjusting paint viscosity or changing the spray tip might also have an effect on the spray pattern, the immediate solution to address the figure 8 formation is to adjust the air pressure. Thus, making a downward adjustment to the air settings is the most effective and direct response to rectify the problem.
