What is the result of poor adhesion in paint application?

Poor adhesion in paint application primarily leads to aesthetic defects in the finished product. When paint does not adhere properly to the surface it's applied to, it can result in various visual problems, such as peeling, flaking, or bubbling. These defects not only detract from the visual appeal of the surface being painted but can also indicate that the paint will not perform effectively over time.

In contrast, increased durability, better color retention, and faster drying time are typically associated with good adhesion. When paint adheres well, it forms a strong bond with the substrate, enhancing its resistance to wear and environmental factors and helping maintain both color and finish quality over time. Therefore, the presence of aesthetic defects due to poor adhesion underscores the critical importance of proper surface preparation and application techniques in paint technology.
