Gamblin Painting Mediums modify the working properties of oil paint from the tube a great deal more than just simply extending the oil colours. From mediums which give a fluid consistency for expressive mark making, to a stiff paste for creating thick, crisp marks, Gamblin Painting Mediums have it all. Broaden the visual qualities of your oil colours, from increasing the transparency of paint layers, to creating a range of surface qualities, from high gloss to matte.
