Schmincke’s Oil Medium W allows oil colours to be mixed with water instead of with turpentine and linseed oil. Brushes and painting tools that have been used with Medium W mixed oils can be cleaned with soap and water. Medium W should be mixed with oil paints in a 1 part medium to 2 parts oil ratio using a palette knife or a spatula. Water can then be added to the mixture to thin the paint and, if necessary, more Medium W.
Medium W increases the gloss and transparency of paints and harmonises the drying process. This odourless, low-solvent additive will reduce the mess and smell of oil painting. When mixed with oils and water, the alkyd resin in Medium W will undergo a shift in colour, however, oils will be restored to their original brilliance and vibrancy on drying. Available in a liquid or gel format.
