The Winsor & Newton Artisan Fast Drying Medium improves the flow and speeds the drying of Artisan oil colours. It will also smooth brushwork and increase the gloss and transparency. This medium is excellent for glazing and producing fine detail, allowing you to create stunning artworks that are resistant to yellowing. This is a very popular medium as it speeds the drying of oil colour by about 50%, allowing further layers to be applied more quickly. When painting in layers it can substitute linseed oil and be combined with water or thinner to maintain the "fat over lean" rule.75mlSmooths brushworkIncreases transparencySpeeds dryingGreat for glazing and fine detailWinsor & Newton Artisan Fast Drying Medium 75ml
