DEMCO EnCouleurs Pouring Medium is permanent and waterproof when dry. Mixed with fluid acrylic colours or drawing inks, it provides an homogeneous and smooth coloured film. The pouring medium gives a glossy relief to a flat surface and creates a water drop effect when applied sparingly. It will retain a high gloss and a wet appearance when dry. It can be used directly from the bottle without adding any colour for a thick varnish effect. The medium is milky in the bottle but will dry clear and glossy once dry.
