Liquitex Professional Effects Medium, 118ml (4-oz), Slow-Dri Fluid Retarder
A fluid that slows the drying time of acrylic paints and mediums by up to 40%. An absolutely essential additive if working in drier climates. Mix into the paint when on the palette to slow the skinning-over of paint and increase blending time. Should not add more than 25% as there is no binder and it can weaken the stability of the paint film when too much is added.
