Which method is used for encapsulating lead paint?

The method for encapsulating lead paint involves applying a sealant over the surface. This technique is specifically designed to contain and control the lead paint hazard without the need for removing the paint entirely. By applying a specialized encapsulant, which is a type of paint-like product formulated to form a barrier over the lead-containing paint, the underlying lead paint is effectively sealed and prevented from posing a risk of lead exposure through dust or chipping.

Encapsulation is often chosen because it can be less disruptive and less expensive compared to complete removal of lead paint, which can release lead dust and exacerbate the issue if not done properly. Moreover, encapsulation allows for the preservation of the underlying structure while managing lead hazards safely.

While other methods, such as removing the paint entirely or covering it with wallboard, could potentially eliminate the lead hazard, they do not fall under the definition of encapsulation, which specifically aims to seal and protect. Painting over with any available paint is also inadequate, as it may not provide a proper barrier or sufficient protection against lead exposure.
