Winsor & Newton Professional Acrylic Slow Drying Medium

Winsor & Newton Professional Acrylic Slow Drying Medium is an additive that slows the drying time of acrylic colour to give you more working time for extended blending and manipulation.

A ratio of 1:1 volume doubles the drying time. Do not mix with colour above 1:1 as excessive amounts will cause the colour to become under-bound, thinner and slightly stickier in consistency.

Maintains no colour shift from wet to dry when used with Artists’ Acrylic. Slows drying to give more working time of colour for extended blending and manipulation.
