Acrylic paintings are ready to varnish after a few days, whereas an oil painting should be allowed to fully “dry” for at the very least three months before final varnishing (some companies recommend up to a year!). Picture varnish creates a complete resin coating that protects the painting underneath. However, oil paint needs to absorb oxygen to fully dry and this is why a final varnish cannot be applied immediately. The thicker the paint, the longer the drying time. If you wish to give temporary protection to the paint surface the application of Retouch Varnish is recommended. It is the varnish’s function to prevent dirt reaching the paint surface. It is much easier to remove a dirty varnish and replace it than to remove dirt from the oil painting itself, potentially damaging the paint-film. Oil based varnishes cannot be easily removed without the likelihood of damaging the picture so are not recommended as a Picture Varnish.
