What type of coatings are used to cover and seal a surface previously coated with lead-based paint?

Encapsulant coatings are specifically designed to cover and seal surfaces that have been previously coated with lead-based paint. These types of coatings form a protective barrier that prevents the lead dust or chips from becoming airborne and posing a health risk. Encapsulants are applied as a liquid that dries to form a flexible, airtight seal, effectively locking in the lead paint underneath and preventing exposure to harmful materials.

In contrast, sealing coatings generally provide a layer of protection or seal against moisture and contaminants but may not necessarily contain features specifically aimed at managing lead. Protective coatings often safeguard surfaces from physical damage or corrosion, but they do not inherently address the issue of lead-based paints. Transformative coatings may change the properties of the underlying material but do not specifically target the hazards associated with lead paint. Thus, encapsulant coatings are the most suitable choice for ensuring safety and compliance when dealing with lead-based paint surfaces.
