Demco Acrylic Retarder - 237ml

Add ample working time to your next acrylic piece! Ideal for wet on wet techniques, Demco\’s retarding medium increases the blending time of acrylics and to reduces skinning of paint on the palette. Experiment by adding small amounts to acrylic paints and mediums, keeping its volume to no more than 25% (over that amount can lead to the paint not drying thoroughly, a poor bond, and possible shrinking of the paint film). This clear liquid medium will not affect the tone of your acrylic colours but will slightly increase its transparency. Available in a 237 ML (8oz) bottle.
