Painting Over Lead Paint

Yes, there is a way to apply paint onto paint that is lead-based; however, not with any kind of paint. Painting over paint that contains lead, also known as encapsulation, is a highly efficient method for removing lead paint. Encapsulation is cheaper than the removal of lead paint, and it's also safer because it does not release dust or lead into the air.

Remember that conventional water- or oil-based coatings aren't encapsulant!

Dangers of Lead Paint

In the beginning, let us be aware that lead-based paint can be extremely hazardous. Be aware while working around lead paint, regardless of whether it's in good or bad condition, by wearing gloves, a respirator, or coveralls, as well as eye protection.

When Not to Encapsulate?

When the paint that you're trying to encapsulate is peeling or flaking off, encapsulation is not the best option for remediation because the encapsulation paint is likely to flake off and peel off the wall, along with the paint. Get suggestions from an expert if you're not sure.

Encapsulation of lead paint is not effective on surfaces that include:

• Walked on
• Rub together
• The condition has deteriorated badly.

If that's the case, you need to choose an EPA-certified renovation contractor.

Painting Over Lead-Based Paint

The process of painting over lead paint or encapsulation is only successful if the original lead paint's finish is in a good state, that is, not chipping or peeling. Furthermore, the encapsulated space should be monitored for time to avoid exposure to dust and lead paint chips. The encapsulation process should last for up to 10 years if it is done properly. If it begins to peel, you must act quickly.

What Paint Should You Use to Encapsulate Lead?

If the conditions are right to paint over the lead paint, there are three kinds of encapsulants to choose from:

• epoxy
• polymer
• cement-type materials

If you plan a DIY undertaking, we suggest an epoxy-based or polymer encapsulation solution because they don't require mixing. They should be applied according to the specifications of the manufacturer. Most often, they are applied using brushes, rollers, or an airless spray gun.
