Video Description

In this video, paint expert Mauro Henrique shows host Kevin O’Connor two practical methods for testing lead-based paint so you can keep your home and projects safe. SUBSCRIBE to This Old House: http://bit.ly/SubscribeThisOldHouse. Lead paint is a common but dangerous substance found in many older homes. When disturbed, it can create dust that leads to brain damage, learning disabilities, and other serious health issues, especially for children and pregnant people. Because of these risks, contractors working on homes built before 1978 must follow EPA lead-safe renovation practices and often start by testing for lead paint.
