What type of paint deterioration includes blistering and flaking?

The correct answer describes a type of paint deterioration characterized by visible changes on the paint surface. Blistering and flaking indicate a failure of the paint's adhesion to the underlying surface. In surface deterioration, the paint's top layer becomes compromised due to factors such as moisture, temperature changes, or improper application. These issues can create air pockets beneath the paint surface, which leads to blistering as the paint lifts away from the substrate and eventually causes flaking when the integrity of the paint film breaks down.

This type of deterioration is particularly relevant for lead risk assessors because deteriorated paint can release lead dust or chips, posing health risks, especially in homes with young children. Understanding the mechanics of surface deterioration helps in assessing the extent of lead risks in residential environments and determining appropriate remediation strategies.
