Liquitex Slow-Dri Gel Retarder when mixed with acrylic colour/medium extends the open time of your colour/medium by 40% rendering it blendable and workable for longer. Being a Gel this product unlike fluid retarders increases viscosity giving a thicker consistency whilst maintaining surface gloss, color depth and transparency.
