Liquitex Metallic Mediums can be used to give paint a metallic effect or to add metallic surface highlights when used on its own. Slowly stir as much Metallic Medium as you like into acrylic colour to get the metallic lustre and viscosity you want - transparent colours give the best results. Note, it will lower the viscosity of heavier bodied paints. If bubbles appear when stirring, leave to sit while they rise and disappear. Liquitex Metallic Mediums extend your colour without affecting its acrylic stability. It also slows down the drying time to help you get more subtle colour blends. Squeeze from the bottle and paint on neat for a semi-opaque gold effect. Liquitex Metallic Mediums are intermixable with all Liquitex products.
