Winsor & Newton's Professional Slow Drying Medium slows the drying time of acrylic paint to give you more working time of colour for extended blending and manipulation. A ratio of 1:1 volume doubles the drying time (mix with colour up to 1:1).

Slow Drying Medium maintains colour viscosity and has no effect on the finished colour when dry.

This medium maintains no colour shift from wet to dry when used with Winsor & Newton Professional Acrylic.
