Winsor & Newton Professional Acrylic Slow Drying Medium

This additive 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.

This additive has been formulated to match the consistency of the colour. This means that none of the characteristics of the colour are affected, except the drying time. You can mix Slow Drying Medium with any other medium in the range to slow the drying. This additive maintains no colour shift from wet to dry when used with Winsor & Newton Artists' Acrylic, unlike other slow drying mediums.

  • Highly recommended

    A new venture into trying acrylics which I have found difficult after watercolour. With this slow drying medium, I am able to easily blend colours - does what it says on the bottle!

    I like this. I like the texture and I like the extra working time.

  • Very Satisfied

    My acrylics stayed wet on the palette for long enough to take a break and not having to throw them away the day after, awesome.
