Artists' Acrylic Slow Drying Medium Winsor & Newton

This medium slows the drying time of acrylic color to give you more working time of color for extended blending and manipulation. A ratio of 1:1 volume doubles the drying time (mix with color up to 1:1). It maintains paint viscosity and has no effect on the finished color when dry. This medium maintains no color shift from wet to dry when used with Artists' Acrylics.
