Lead-based paint is typically found on surfaces painted before what year?

Lead-based paint is typically found on surfaces painted before 1978 because that is the year when the U.S. Consumer Product Safety Commission banned the use of lead-based paint in residential properties. Lead was added to paint to enhance its durability and drying properties but posed serious health risks, particularly to young children and pregnant women. As a result, homes and buildings painted before this date are considered at risk for lead exposure, making it essential for renovators and homeowners to assess the presence of lead-based paint before undertaking any remodeling or repair work. This historical context highlights why 1978 is a critical year and underscores the importance of awareness and safety measures in homes built before that time.
