What effect does using a high volume of air have during the spray painting process?

Using a high volume of air during the spray painting process enhances the atomization of the paint. This means that the paint particles are broken down into smaller droplets, allowing for finer misting when the paint is applied. Lower pressure atomization results from the way in which a large volume of air can carry and distribute the paint particles more effectively. This leads to a smoother and more even application across the surface being painted, reducing the likelihood of imperfections.

When looking at the other options, it's evident that they focus on different aspects of the spray painting process. Thicker paint application generally refers to the adjustment of material viscosity rather than air volume alone. A higher chance of runs and sags is typically associated with excessive paint application rather than the air volume itself. Lastly, while increased durability of the finish can be a consideration in the overall painting process, it isn't directly tied to high air volume as the primary factor. Thus, the use of a high air volume mainly influences how paint is atomized, promoting lower pressure atomization and a more refined application.
