What does gun travel speed determine during the painting process?

Gun travel speed significantly influences how much material is applied during the painting process, which directly relates to the build of the paint layer. When the gun is moved faster, less material is deposited on the surface, resulting in a thinner layer. Conversely, if the gun is moved more slowly, a thicker layer of paint will be applied. This control over material application is crucial for achieving the desired coverage, durability, and finish quality.

This concept is essential in ensuring that the correct amount of paint is applied for optimal adhesion, color depth, and finish properties. Factors like the gun's distance from the surface, the rate of material flow, and the painter's technique also play a role, but gun travel speed is a primary determinant in the paint application process.
