DEMCO EnCouleurs pouring medium is permanent and waterproof once dry. Mixed with fluid acrylic colors or colored inks, it produces a colored, homogeneous and smooth film. Pouring medium gives relief and shine to flat surfaces and helps create a droplet effect when applied sparingly. It retains a high gloss and a wet appearance when dry. Can be used directly from the bottle without adding color for a thick varnish effect. In its pure state, the pouring medium will have a milky effect but will become completely clear and shiny when dry.
