What is a common cause of paint failure during refinishing?

Inadequate surface preparation is a critical factor that can lead to paint failure during refinishing. Proper surface preparation involves cleaning, sanding, and priming the surface to ensure that the paint adheres well and provides a durable finish. If the surface is not properly prepared—such as being dirty, greasy, or not sanded appropriately—this can create an unstable foundation for the paint.

Without adequate preparation, the paint may not bond effectively, leading to issues like peeling, blistering, or premature wear. It is essential for any refinishing project to follow thorough preparation protocols to achieve optimal results and ensure the longevity of the paint job. This emphasis on preparation is foundational in painting and refinishing practices, making it a primary focus in professional training.

While factors like lighting conditions, color choice, and the number of paint coats applied can influence the aesthetic result of the project, they do not directly affect the paint's ability to adhere to the surface, which is why surface preparation is a more critical concern regarding paint failure.
