What might result in a paint job that is heavy with sagging, ripples, or orange peel?

A paint job that exhibits heavy sagging, ripples, or an orange peel texture is often influenced by the quality and consistency of the paint application. A dirty air nozzle can disrupt the proper atomization of the paint as it exits the spray gun. This uneven application causes the paint to settle improperly on the surface, leading to imperfections such as sags and ripples. When the nozzle is clogged or contaminated with paint build-up, it may produce inconsistent spray patterns that contribute to these undesirable features in the finished appearance.

In contrast, while high air pressure can cause problems, it typically leads to fine misting and can also result in paint overspray rather than sagging. Over-thinning the paint can also introduce issues, but it generally affects coverage and adhesion rather than causing sagging. Lastly, holding the spray gun too close to the surface tends to lead to too much paint being applied in a localized area, potentially creating drips rather than an overall texture issue.

Understanding the mechanics of the spray equipment and the condition of the nozzles is crucial for achieving a smooth and professional paint finish.
