Winsor & Newton Artist Slow Drying Medium

Winsor & Newton Professional Acrylic Medium, Slow Drying Medium maintains no color shift from wet to dry when used with Winsor & Newton Professional Acrylic. Slows drying to give more working time of color for extended blending and manipulation. A ratio of 1:1 color to additive volume doubles the drying time. Maintains color viscosity and has no effect on the finished color when dry.
