“Natural paints”, that are mainly made from vegetable oils are considered to be less hazardous to health than organic paints. They do not have a clear definition or classification by constituents. This study aims to determine the effects of “natural paints” application with different compositions to wood on the indoor air quality. Natural paints containing organic components had worse perceived air quality than the natural paints owing to the pungent odor of aldehydes and alcohol. In the natural paints, high release of terpenes derived from vegetable oils had a masking effect on aldehydes.
