Liquitex Slow-Dri Fluid Retarder Medium 118ml Bottle

Slow-Dri Fluid Retarder Medium is an excellent choice when working in low humidity, or whenever in­creased workability and blending time of acrylic paints and mediums is desired. This medium will retain brushstrokes and add body to lower viscosity acrylic colours.

You should not add more than 25% of Slow-Dri Fliud Retarder as there is no binder in it and it can weaken the stability of the paint film when too much is added.
