Atelier 250ml Retarder Medium
Atelier Retarder Medium slows down the drying process when added to artists’ acrylic paint and mediums.
Atelier Retarder Medium is particularly useful when painting wet-over-wet or wet-over-dry techniques. Retarder Medium makes blending with acrylic colours easier and may be added to other Atelier Mediums to increase their working time.
When large amounts of Retarder Medium are used, acrylic colours may be reactivated when overpainted.
After a few days, the Retarder Medium itself evaporates, leaving the performance of the dry paint film unchanged. Clean up with mild soap and cool water. Water based, non toxic.
