From Winsor & Newton's Galeria range comes the Acrylic Fluid Retarder, a liquid medium that extends the drying and working time of acrylic paint in just a few drops. Perfect for working on larger acrylic paintings, this fluid retarder also helps smooth the blending and manipulation of colours, and can be used as a thinner if used in larger quantities.

Please note, the Acrylic Fluid Retarder does not contain enough acrylic resin to act as a "binder" and should only be used in the amount needed. Any more than a 25% retarder / 75% paint ratio may result in the paint not drying at all.

  • Available in a 250ml bottle.
  • Fluid, liquid retarder.
  • For extending the drying and working time of acrylic colours.
  • Offers smoother blending and manipulation of colours.
  • Only a small amount is needed for extended working time.
  • Made by Winsor & Newton.
