Wish you could magically slow down the drying time after freshly painting? Sax’s True Flow Acrylic Drying Retarder is your dream solution, keeping paints wet and workable for up to 3 times longer! Drizzle the clear solution directly into your acrylics, onto your base coat, or even add with water to a spray bottle for misting over your canvas and palette before starting paintwork, which helps break the surface and instantly allow for smooth brush strokes. Addition of small amounts of retarder to acrylic paints and mediums will not alter colors. Comes in break-resistant plastic bottle of 1 pint capacity. Conforms to ASTM D-4236. Non-toxic with AP certified seal of the Art & Creative Materials Institute, Inc. (ACMI). Freeze/Thaw stable.
