Winsor & Newton's Professional Acrylic Flow Improver increases the flow of acrylic paints, allowing the application of areas of flat, even colour without changing colour strength.

Flow Improver is also effective for hard edge painting techniques. It maintains the stability of the colour and slightly slows drying.

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