DecoArt Traditions Artist Acrylic Extender and Blending Medium, 8-Ounce
A medium for extending the "open" or working time of the Traditions paints and mediums. This medium is added to slow the drying of the paint. It can also be safely added to the other mediums in the line. Anytime you want the paint or medium to have more working time, add some Extender to it. It also allows the acrylic artist to perform oil techniques. This medium has no solids in it so when the paint or medium is dry, there will be nothing added.
