Winsor & Newton Galeria Fluid Retarder 250ml

For extending the drying and working time of acrylic colours.

Small amounts (a few drops) 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.

Do not over-mix as this may cause acrylic colour to dry tacky or not dry properly.
