Interior paints and finishes may contain volatile organic compounds (VOCs) as a plasticizer. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects, including eye, nose, and throat irritation; headaches; loss of coordination and nausea; allergic skin reactions; and damage to the liver, kidneys, and central nervous system. Certified low/no-VOC finishes help protect indoor air quality for both occupants and construction workers. Best practices also include airing out the house thoroughly during construction and in the first few weeks after paints and sealants have been applied when any VOC concentrations would be at their highest.
