Atelier Retarder - 250ml
A paint additive designed to slow down the drying time of acrylic paint. It may be added to other Atelier mediums to increase open time. Note: Retarder does not contain a binding agent so to avoid creating an unstable mixture, it is recommended to mix no more than 10% with acrylic paints.
