Winsor & Newton Galeria Acrylic Fluid Retarder 250ml

For extending the drying and working time of acrylic colours by up to 50%. Small amounts (a few drops) added to the paint will allow for extended blending and manipulation. Fluid Retarder does not contain sufficient acrylic resin to act as additional "binder" and should be used only in the amount needed to achieve the desired effect. Anymore than a ratio of 25% to 75% (retarder to paint) may result in the paint not drying at all. Will also act to thin the paint if large quantities are added.
