Encapsulation is a method used to manage lead-based paint hazards by sealing the lead paint surface to prevent its deterioriation and the release of lead dust. However, its effectiveness can be compromised when significant adhesion problems are present. When three or more accessible surfaces show signs of adhesion problems, encapsulation is considered inadequate. This is because such issues indicate that the lead paint is likely to continue to deteriorate, posing a risk as the encapsulant may not adhere properly, leading to potential exposure to lead dust or chips.

In cases where there are two or fewer accessible surfaces with no visible adhesion problems, encapsulation could still be a viable option. A small room size, such as less than 100 sq. ft., does not automatically rule out encapsulation but may have specific considerations depending on the overall conditions and state regulations. Therefore, the presence of multiple problematic surfaces indicates an inability to ensure that encapsulation would be effective, marking this scenario as a clear reason to rule out this method.
