Which term describes the delamination of several top layers of paint from underlying layers?

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

Answer: (B)

Delamination across several paint coats from the layers beneath is described as multi-coat failure. This term specifically captures the failure occurring between multiple coats, where several top layers detach together from the underlying layer instead of a single layer peeling off. This differs from surface coat failure, which would involve the outermost layer failing its adhesion, not the entire stack. Paint abrasion refers to wear from rubbing or friction, and chipped paint means chunks of coating breaking away rather than layers separating. So, when several coats come away as a unit, the situation is best described as multi-coat failure.
