Combine acrylic paint with Amsterdam mediums and see how the character of the paint changes. Amsterdam Extra Heavy Matt Gel Medium reduces the gloss and increases transparency of acrylic colours while retaining the viscosity. Considerably increases the brush stroke and enables the application in one stroke of extremely thick layers of acrylic colour. When used on it's own, Gel Medium can also be used in collage and mixed media to adhere a variety of materials to your surface. White in colour but dries colourless. Waterproof once dry. 250ml.
