This medium decreases the gloss of the colour. Its gel consistency is thicker than the Matt Medium, matching the luxuriously thick and buttery consistency of the colour. Hence when mixed with colour the thickness of the colour is maintained, so the paint retains brush strokes and palette knife marks for excellent impasto effects. This means you can change the paint without compromising the feel. It dries to give an even matt finish. This medium contains clear binder and matting agents giving you no loss of colour depth when used with Winsor & Newton Artists' Acrylic.
