What can result from inadequate surface preparation before applying coatings?

Inadequate surface preparation before applying coatings significantly impacts the performance and durability of the coating. Proper surface preparation ensures that contaminants, such as dirt, grease, and old coatings, are removed, allowing for optimal adhesion between the new coating and the substrate. When surfaces are not prepared correctly, the chemical and physical bond between the coating and the surface can be compromised, leading to poor adhesion. This weak bond can ultimately result in premature failure of the coating, which may take the form of peeling, blistering, or chipping. Such failures not only diminish the appearance and effectiveness of the coating but can also expose the underlying material to corrosion and other forms of damage. Thus, ensuring adequate surface preparation is critical to achieving a durable and long-lasting finish.
