What common issue is caused by inadequate surface preparation or overly thick paint application?

The common issue resulting from inadequate surface preparation or excessively thick paint application is the occurrence of spray paint sags and runs. This can happen when the paint is applied too thickly, leading to an inability of the paint to adhere uniformly to the surface, resulting in an uneven coat that can pool and cause sagging.

Moreover, proper surface preparation is essential in ensuring that the paint adheres correctly and evenly. If the surface is not adequately cleaned, primed, or prepped before painting, it can lead to poor application results, such as drips or runs. Consistency in paint application is crucial, and any variances in thickness contribute to noticeable imperfections in the finish, commonly manifested as sagging paint.

Understanding the importance of following recommended guidelines for both surface preparation and the required application thickness is vital in achieving a professional and durable paint finish.
