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. UK shipping by road only. Not available for International or Northern Ireland delivery.
