Sax acrylic matte medium removes pesky paint reflection on paper and canvas. Use the unique formula by mixing or applying over your acrylic or other water-based paints to extend paint volume and color, and simultaneously decrease unwanted gloss or shine. The painting sealant leaves a flat, clean matte sheen once dried. Our acrylic medium also helps with the ease of flow of paint and adds adhesion to paint films. Use the solution as an extender, a fixative, or a ground (creating toothy texture that is similar to that of papers used with pastel and chalk).
