Retarder is an accessory for the acrylic range.
It slows the drying of applied colours and prevents airbrush clogging.
A longer drying time allows for a more even flow and creates an even more
perfect surface of dried film. Retarder can be added directly to a colour,
water or a thinner. We recommend adding a maximum of 30 % of retarder. The
higher the quantity of Retarder the longer the drying process takes. Additional
diluting with water or thinner after addition of Retarder is possible.
It is not recommended to pour a colour mixed with Retarder back into its pot.
Retarded colour cannot be stored for a long time.
Retarder also works very well together with alcohol based colours, especially for brush applications.
