Lead-based paint poses a health risk to children and adults alike if the fumes and dust chips are either inhaled or ingested. In the late 1970s, the U.S. Consumer Product Safety Commission established a limit on the level of lead that could be in paint. Encapsulants are materials that can be used to prevent exposure to lead-based paint.
What are Encapsulants?
Encapsulants are materials that are applied over lead-based paint to seal the paint to a surface and prevent the release of paint chips or dust. Encapsulants are available in both liquid and adhesive forms.
How Encapsulants Work
Encapsulants create a barrier over the lead paint, sealing in dangerous dust and paint chips from environmental exposure, and by extension, human contact. It’s best to employ the use of encapsulants on solid, clean, dry surfaces. Encapsulants are not suited for surfaces that see foot traffic, rub together, or have extensive damage.
Types of Encapsulants
- Polymers (chemical compounds): These create a flexible, resilient, thin barrier, and require the use of an airless spray gun, brush, or roller for application.
- Epoxy or polyurethane polymers: These create a hard, but flexible barrier on the surface and are applied using an airless spray gun, brush, or roller.
- Cement-like materials with polymers: These require curing to create a thick coating and are typically applied with a trowel.
Things to Consider Before Using Encapsulants
- Adhering to the manufacturer's guidelines for testing, preparation, and application is a must. Encapsulants are not always the best solution and often encapsulant manufacturers recommend testing prior to application.
- Manufacturer’s standards must be met by the person doing the onsite surface testing.
- Periodical inspection is necessary after encapsulant application to check for damage and to make repairs if necessary. Because encapsulants do not permanently deal with lead paint, further testing will be needed.
- Use the appropriate encapsulant for the specific type of situation for which you need a solution and stick to the manufacturer’s instructions and recommendations.
- Some thicker encapsulants could damage architectural detail, like moldings.
- Manufacturer’s specifications must be met by the person applying the encapsulant.
- Periodic inspection and maintenance are not necessary for replacement doors and windows, or for the full removal of lead paint.
Advantages of Encapsulants
- As long as dust is not released, residents can remain in the building at the time of surface preparation and application.
- Surface preparation may not be necessary if the surface is intact.
- Encapsulants may be more economical and time-saving than lead paint removal
