Open thinner - 4 oz

Golden Open Thinner is a water-based additive designed to thin the consistency of Open Acrylics without altering open time, as well as to maintain and adjust the workability of colors on the palette. Open Thinner contains no binders, does not form a film, and should never be used alone. Add sparingly to acrylic paints, starting at approximately 10 parts paint to 1 part thinner. Maximum addition is 3 parts paint to 1 part thinner. Open Thinner can also function as a thin-bodied retarder when used
