Which term describes the condition where the top layer peels away from underlying layers?

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

Answer: (A)

Peeling of the top layer from the layers beneath is called surface coat failure. This occurs when the topcoat loses adhesion to the underlying coats or substrate, so it lifts, blisters, or flakes away. Causes include inadequate surface preparation, moisture trapped under the paint, temperature cycling, or applying incompatible coatings. This is different from abrasion (wear from friction) or chipped paint (mechanical damage that breaks pieces off), and it’s not about multiple coats failing together.
