Lead paint was commonly used in homes and buildings before it was banned in the late 1970s. However, some buildings still have lead paint on their walls, and it can be a hazard for those who live or work in them. One question that often arises is whether painting over lead paint will make it safe.
What is Lead Paint?
Lead paint is paint that contains lead as an additive. It was commonly used before the 1970s because it was durable and easy to apply. However, it was later discovered that lead is toxic and can cause a range of health problems, especially in children and pregnant women.
Health Risks of Lead Paint
Lead paint can cause a range of health problems, including:
Learning difficulties and developmental delays in children
Behavioral problems in children
Anemia
High blood pressure
Kidney damage
Nerve damage
Can Painting Over Lead Paint Make it Safe?
Painting over lead paint can be an effective way to reduce the risk of exposure to lead. However, it is important to note that it does not make the lead paint safe. Over time, the paint can deteriorate and release lead dust into the air, which can be inhaled or ingested.
Preparing to Paint Over Lead Paint
Before painting over lead paint, it is essential to prepare the surface properly. This involves:
Cleaning the surface with a wet cloth to remove any dust or debris
Sanding the surface to create a rough surface for the new paint to adhere to
Removing any loose or peeling paint
Using a paint stripper to remove any remaining lead paint
Painting Over Lead Paint
When painting over lead paint, it is essential to use a high-quality paint that is designed for use on surfaces that may contain lead. This will help to reduce the risk of the paint peeling or flaking, which can release lead dust into the air.
Encapsulation
Encapsulation is another option for dealing with lead paint. This involves applying a specially designed coating over the lead paint to seal it in place. However, encapsulation is not always effective and may not be suitable for all situations.
Professional Help
Dealing with lead paint can be dangerous, and it is important to seek professional help if you are unsure about how to proceed. A professional contractor can test for lead paint and provide advice on the best course of action.
Conclusion
While painting over lead paint can help to reduce the risk of exposure to lead, it is not a permanent solution. It is important to prepare the surface properly and use a high-quality paint designed for use on surfaces that may contain lead. If you are unsure about how to deal with lead paint, seek professional help.
