Acrylic Mediums - Winsor & Newton Galeria - Fluid Retarder (SLOW DRYING MEDIUM) 250ml

  • £13.35

Extends the drying and working time of acrylic colours, mediums and gels by up to 50%. A few drops allows for extended blending and manipulation.

Do not add more than 25% of the retarder to the colour otherwise paint might not dry, as Fluid Retarder does not contain sufficient acrylic resin to act as additional “binder” it should  only be used  in the amount needed to achieve the desired effect.
