Liquitex Slow-Dri Gel Retarder Medium 237ml Jar

Slow-Dri Gel Retarder Medium is 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 Slow-Dri Gel Retarder into acrylic paint when on the palette to slow the skinning-over of paint and increase the blending time.

You should not add more than 25% of this product to the paint as there is no binder and it can weaken the stability of the paint film when too much is added.
