Winsor & Newton Oil Colour Medium Artists' Matte Varnish 250ml
Winsor & Newton Artists' Matte Varnish maintains painting for longer. Sealing the microscopic pores on the oil paint film provides resistance to dirt and grease as well as creates a matted surface. Removable, for the purpose of re-varnishing, use a solvent such as Artists' White Spirit or Distilled Turpentine. Quick drying. Non-yellowing, it does not bloom or crack.
Do not use until painting is completely dry (6-12 months). Do not use as a medium. Shake well before use.
