Tri-Art Retarder is a water based medium designed to slow down the drying time of acrylic colours. Mixed with colours and mediums at up to 15%, it increases open-time and allows for greater manipulation. Retarder is essential in airbrush application. When used in correct proportions with Tri-Art Airbrush Acrylics, it extends the drying time, reduces build up on the airbrush tip and will not alter the integrity of the paint film. It is also effective when used with Tri-Art High Viscosity Acrylics for screen printing, as it will prevent the rapid drying of paint in the screen.
Tri-Art Retarder Gel is a thick gel format of Retarder and is formulated for use with Tri-Art's High Viscosity paints and mediums. Ideal for plein-air painting, mono printing and any other technique that requires paint to be wet for longer periods of time. For optimal results do not use more than 20% Retarder Gel with any quantity of paint.
