Grumbacher Linseed Oil Medium for Water-Mixable Oil Paints The same finest quality alkali refined linseed oil offered in our conventional linseed oil, but scientifically modified to be completely water-miscible. Improves flow and water-mixability of MAX Water Mixable Oil Paints and mixtures of MAX colors and conventional oils as well as increasing gloss. Compatible with all known conventional oil painting materials, but will not make them water miscible. MAX Linseed oil is not recommended for use with non-Grumbacher brands of water miscible/mixable oil paints. No solvents needed may be thinned with water. Clean up is as easy as washing brushes and tools with soap and water. Made in USA.
