When should the trigger of the spray gun be fully depressed?

The trigger of the spray gun should be fully depressed until the end of the panel is reached to ensure an even and consistent application of the paint or finish. This technique helps achieve the proper coverage and reduces the risk of uneven layers or stripes on the painted surface.

Maintaining a fully depressed trigger throughout the stroke allows for an uninterrupted flow of material, resulting in a smoother finish. It also helps in maintaining a steady distance from the surface being painted, which is crucial for avoiding issues such as sagging or runs.

Using any other method, such as only depressing the trigger at the beginning or halfway through the stroke, may lead to inconsistent coverage and make it challenging to achieve a professional-looking finish. Likewise, releasing the trigger at the end of every stroke can create a pattern of uneven paint application, potentially necessitating additional work for touch-ups or corrections.
