What Is A VOC?
VOC stands for Volatile Organic Compound and these contribute to atmospheric pollution when they evaporate (while you're painting). There are chemicals used in all industries that are classified as VOCs, from paints and building materials to soaps and cleaning products. As a rule of thumb, water-based paints generally very little VOCs, whilst traditional oil-based paints contain some, but in very insignificant levels. If you suffer from asthma it’s definitely worth choosing a zero VOC paint, otherwise, the decision is usually just a preference for one type of paint over another.
