Which term describes paint rubbing due to mechanical friction?

• A. Paint Abrasion
• B. Chipped Paint
• C. Surface Coat Failure
• D. Multi-Coat Failure

Answer: (A)

Paint abrasion is the wear that happens when paint is rubbed away by mechanical friction. When surfaces are constantly rubbed, scraped, or brushed against each other, the top layer of paint wears off, leaving a dull or bare area. This specific rubbing or friction process is what defines abrasion. Chipped paint, by contrast, results from impact or stress that causes chunks to break away rather than gradual wear from rubbing. Surface coat failure is a broader term for failures within the coating system that aren’t necessarily caused by rubbing, such as poor adhesion or moisture-related issues. Multi-coat failure refers to problems occurring across several layers, not the mechanism of wear.
