What is the result of improper adhesion in paint application?

• A. Crisp lines in paint
• B. No effect at all
• C. Cracking and peeling over time
• D. A shiny finish

Answer: (C)

Improper adhesion in paint application often leads to cracking and peeling over time. This occurs because when the paint fails to bond properly to the surface, it cannot withstand environmental stresses such as temperature changes, humidity, and mechanical impacts. As a result, the weakened layer of paint can develop cracks and ultimately peel away from the substrate, exposing it to further damage and corrosion.

In contrast, crisp lines in paint are indicative of proper application techniques and good adhesion, while a shiny finish is a characteristic of the paint’s gloss level, which is not directly related to adhesion. Lastly, stating that there is no effect at all disregards the significant issues that can arise from inadequate bonding.
