Medium viscosity. A thick, low luster, fine texture gel, that dries to a light gray matte stucco finish. Excellent for producing thick 3-D effects, as well as thinly coating surface. Excellent ground for acrylic and oil paint, oil pastel, oil bars, pastels and graphite. Somewhat susceptible to abrasion. Coat with Liquitex® Varnish for added protection. Apply varnish carefully to avoid foaming and clouding. Works well with brush application
