How do artists achieve a metallic sheen on polypropylene surfaces?
Artists achieve a metallic sheen on polypropylene surfaces through a combination of specialized materials and techniques. First, the surface must be properly prepared by cleaning and lightly sanding to ensure adhesion. A primer designed for plastic, such as an adhesion promoter, is often applied to create a suitable base. Next, metallic paints—typically acrylic or enamel-based with fine metallic pigments—are layered evenly. For enhanced shine, artists may use techniques like dry brushing or applying a glossy topcoat. Heat-setting or UV-resistant sealants can also be used to protect the finish. The result is a durable, reflective surface that mimics the appearance of metal.
