â¢ OIL PAINTING (noun) The noun OIL PAINTING has 2 senses: 1. a picture painted with oil paints. 2. the art or method of painting with oil paints. Familiarity information: OIL PAINTING used as a noun is rare.
Oil paint dries by oxidation, not evaporation, and is usually dry to the touch within a span of two weeks (some colors dry within days). It is generally dry enough to be varnished in six months to a year. Art conservators do not consider an oil painting completely dry until it is 60 to 80 years old.
