The Daler Rowney Linseed Stand Oil is a pale, viscous oil medium engineered to reduce the consistency of oil paints while smoothly enhancing their flow. It levels exceptionally well to minimize visible brush marks, drying slowly into a tough, elastic film that creates a beautiful enamel-like finish. This high-quality, refined medium is resistant to yellowing, making it an excellent choice for building up glossy glazing layers in professional oil paintings.
