Remove that pesky paint reflection with Sax True Flow Acrylic Medium. This unique formula is for use with mixing or applying over your acrylic or other water-based paints to extend paint volume and color, and simultaneously decrease unwanted gloss or shine. Leaves a flat, clean matte sheen once dried. Acrylic medium also helps with ease of flow of paint, and adds adhesion of paint films. Use as an extender, a fixative, or a ground (creating toothy texture that is similar to that of papers used with pastel and chalk). This acrylic media comes in clear bottle of 1 quart capacity. AP Certified. Freeze/Thaw stable. Non-toxic.
