Recent studies have proven that lead-based paint causes mental disorders in small children. Problems can arise from simply breathing the paint dust in the air. There have been cases where a painter comes home from work and pets the family dog before he showers, then dog gets petted by his children, which, in turn, caused them to have mental disorders. If your home was built before 1978 and you are considering having it painted, be sure to have it tested for lead-based paint, and hire a professional painter certified by the EPA for lead-based painted homes. –A tip from your Colorado Springs Painting contractor, RC Painting.
