Encapsulation creates a protective barrier by sealing lead-painted surfaces with a durable coating. This coating adheres well and stays intact, so it prevents the paint from deteriorating, chipping, or generating lead dust that can expose occupants. It’s a good option when the existing paint is in reasonably good condition and the surface isn’t heavily worn or damaged, because the barrier remains effective only if the underlying paint isn’t flaking. Proper surface preparation and curing are important to ensure the encapsulant sticks and lasts. This approach is not about adding ventilation, removing all paint, or simply choosing any color of paint; it’s specifically about sealing the lead-containing surface to reduce exposure while the paint remains in place. If surfaces are peeling or subject to heavy abrasion, other approaches—like removal or enclosure—may be more appropriate.
