Which of the following describes peeling from masonry surfaces?

Peeling from masonry surfaces is best described as layered deterioration. This phenomenon occurs when layers of material, such as paint or plaster, begin to separate or peel away from the underlying masonry due to factors like moisture, thermal expansion, and poor adhesion.

Layered deterioration specifically emphasizes the breakdown of distinct layers or coatings that have adhered to the masonry, which can be a critical issue in assessing lead risks, especially when those layers contain lead-based paint. Understanding this process is vital for risk assessors, as it directly relates to how lead hazards may be present in deteriorating structures.

In contrast, the other options either do not accurately capture the essence of peeling from masonry surfaces or pertain to different types of deterioration, such as general degradation or flaking that may not involve the layered aspect. For example, paint flaking is a more specific description of the failure of the paint's bond, but it does not encompass other layers that may also be deteriorating.
