Speedball Matte Medium is used for extending Speedball Acrylic Paint and minimizing gloss. It can be used as a substitute for gesso on canvas when a translucent ground is desired. This medium may be used as a top coat to create a "flat" finish. Great for collage, decoupage, scrapbooking, altered book-making and faux finishing. Available in pint, quart and gallon sizes.
