What is essential to achieve a good finish when using a spray gun?

Achieving a good finish when using a spray gun significantly relies on following proper flash and dry times. Flash time refers to the period needed for the solvents in the paint to evaporate before the next coat is applied. This is crucial because it allows the layers of paint to bond effectively, promotes even coverage, and reduces the risk of issues such as runs, sags, or an uneven texture. If these times are not adhered to, the layers may not adhere properly, leading to a compromised finish.

Additionally, dry times ensure that the underlying layer is adequately set before a subsequent layer is added. This prevents excessive solvent entrapment and allows for a more durable finish. When proper timing is observed, it contributes significantly to the overall quality and longevity of the paint job.
