It allows you to mix oil paints with water instead of turpentine or linseed oil. There is no need to use harmful solvents, and cleaning your tools with just soap and water becomes easy. As for drying and varnishing, proceed in the usual way, just as you would with any oil painting. Mix the medium with oil paints using a palette knife in a 1:2 ratio (medium : oil paints). You can then add water to the mixture to further thin the paint, and if necessary, add another portion of Hydropower medium. The medium increases the gloss and transparency of the paints and harmonizes the drying process. This odorless auxiliary agent (with low solvent content) helps reduce the characteristic odor of oil paints and the associated cleanup issues.
