Jo Sonja’s Retarder Medium, 250ml. Slows the drying of Jo Sonja’s colours and mediums, which helps when air conditioning, heating or hot weather makes acrylics dry too fast.
Dip your brush in as you paint, mix it into the paint, or coat the whole surface for wet-on-wet work. Paint with retarder can feel dry but stay soft for a few days, so be gentle before the next step.
