Schmincke Medium W for oil paint 60ml This medium is special for mixing oil colors with water instead of turpentine. It does not affect the composition of the oil paintings since it not only maintains the brightness and transparency equally, but also increases it. It also influences the drying process of the paint. It is recommended to shake before use. You must mix 2 parts of oil with 1 part of medium to obtain the desired consistency and optimal results. Later you can add water to taste. This medium also makes it possible for you to brush your brushes with water, since in this case the water would act as a diluent just as turpentine would do. It is composed of alkyd resin. Contains 60 ml. Brand: Schminke.
