The Lean Painting Medium is for use in the first layers of an oil painting and gives an excellent flexible 'key' and stable foundation for further oil work.

Ideal for thinning oil paint to a thin flowing consistency for an underpainting or grisaille and oil sketches. Also great for painting wet-in-wet and with oil pastels and oil bars. Dries to a strong, flexible film with non-yellowing properties.

Can be thinned with Zest-it Oil Paint Dilutant and Brush Cleaner. Touch dry in 12 to 24 hours depending on ambient temperature.




Zest-it is not classed as a toxic substance, nor is it classed as flammable but have 'safety sense' and keep it away from flames or sparks and don't heat it up. If you have a known allergy to citrus fruit then it may be best not to use this product.

Zest-it isn't irritating to the eyes or skin in normal use, although splashes may irritate, just like soap when you get it in your eyes. Used normally with good hygiene it should not irritate the skin.
