What type of paint is likely to contain lead?

The most likely type of paint to contain lead is oil-based paint. Historically, lead was added to oil-based paints to enhance durability, increase shine, and accelerate drying time. Because oil-based paints were commonly used in homes, especially in the early to mid-20th century, there is a higher risk that homes painted during that time may have lead-containing oil-based paints.

Water-based paint, latex paint, and acrylic paint generally have a lower likelihood of containing lead, especially in modern formulations, as regulations have restricted the use of lead in paint since the late 1970s. These types of paints became popular after awareness of lead's adverse effects emerged, leading manufacturers to eliminate lead from their formulations in favor of safer alternatives. Understanding the historical context and changes in manufacturing regulations is crucial for recognizing the prevalence of lead in various types of paint.
