Artisan Fast Drying Medium can be used to improve the flow of Artisan Water Mixable Oil Colour and speed up drying. It also increases gloss and transparency and reduces the appearance of brush strokes, making it excellent for glazing and creating fine detail. The medium is resistant to yellowing.

By speeding the drying of oil colour by about 50%, Artisan Fast Drying Medium thins the colour and allows further layers to be applied more quickly. If you are painting in layers, it can replace linseed oil and be combined with water and/or thinner to maintain the “fat over lean” painting rule.
