Zest-it Clear Painting Medium is a blend of Zest-it Oil Paint Dilutant and Brush Cleaner with Linseed Stand Oil.

  • It thins oil paint to improve flow, enables wet-on-wet painting techniques, and adds gloss for glazing, drying to an enamel-like finish.
  • It will also accelerate drying, to make oil colours touch-dry in about 12-24 hours.
  • Like Zest-it Oil Paint Dilutant and Brush Cleaner, it is based on the zest of citrus fruit and, as well as having a lovely citrus aroma, is kind to the environment.

11th December 2014 Reviewed by Kenneth Karl I just started using and i'm enjoying the experience very much. I have tried everything over the years and this medium is up top with some of the major old favorites out there. Plus I conceder this The main reason I like it is it's safe to use and breath. My oils have taken on a smother, thicker feel using this and I recommend it to all oil painters to get away from their beloved turps.

10th July 2014 Reviewed by Susan Hall I found this on Cass Art website when I decided that I needed something other than standing oil. This product is much lighter and really improves the flow of the oil paint. Great stuff!
