What is described by multi-coat failure in paint?

Flaking of a single coat
Top layer failing but staying visible
Delamination of multiple paint layers
Uniform surface texture

The correct answer is: Delamination of multiple paint layers

Multi-coat failure in paint refers to the delamination of multiple paint layers. This phenomenon occurs when the adhesion between these layers breaks down, causing them to separate from each other and from the surface beneath. This type of failure is particularly significant in the context of lead-based paints because it can expose underlying surfaces, potentially releasing lead dust or chips, which pose health risks. When assessing paint conditions, recognizing multi-coat failure is crucial because it indicates more severe paint deterioration than simply a single layer flaking away. This not only affects the aesthetic quality but also raises concerns regarding potential lead contamination. Understanding the mechanics of paint adhesion can help in developing appropriate remediation strategies to address such failures effectively.
