Amsterdam Acrylic Gloss Medium can be used as a thinner for acrylic paints that helps to keep the glossy finish of acrylics but doesn't effect the overall durability of the paints themselves. Gloss Medium dries colourless and transparent and when added to acrylic paint it doesn't compromise the drying time.
Amsterdam Acrylic Gloss Medium can be thinned with water, and becomes waterproof when fully dry. Also useful for increasing the flexibility of acrylic paints, and dries to a high gloss finish
