A matte version of Langridge Painting Medium for adding fluidity and improve paint handling. It quickly dries to a tack but remains fresh so that it may still be painted into. Stand Oil base ensures non-yellowing of artwork. Caution should be used when painting with deep tones as the matting agent raises the tonal values slightly. (Stand Oil, Linseed Oil, Gum Turpentine, Matting Silica, Cobalt Driers).
