What type of paint is most likely to contain lead, especially in homes built prior to 1978?

Oil-based paint is most likely to contain lead, particularly in homes constructed before 1978. During this period, lead was commonly used as a pigment and drying agent in paints. The use of lead in residential paint was widespread due to its desirable properties, providing better durability and finish compared to other types of paint.

In 1978, the U.S. government banned the use of lead-based paint in residential properties due to health risks associated with lead exposure, particularly in children. Although other types of paint, such as water-based and acrylic paints, became more popular after this ban and generally do not contain lead, oil-based paints retain the highest likelihood of containing lead in older homes.

Understanding the prevalence of lead in oil-based paints helps assess risks during remediation, renovation, or testing for lead exposure, ensuring proper safety measures are in place for those living in older homes.
