Winsor and Newton Professional Matt Varnish

 A quality UV resistant artists' matte varnish that 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). Shake well before use.
