Pearl Ex Powdered Pigments can be mixed into any almost media and applied to almost any surface! They are extremely versatile and can produce a nearly endless variety of finishes - from metallic sheens, to pearlescent shimmers, to all manner of faux finishes. Pearl Ex creates a metallic look without being a metal. The particles are flat platelets with two surfaces, therefore it lays down beautifully like a thin coating of metal. The different particle sizes produce different looksÃ¹from a fine, smooth, pearly luster to a highly metallic sheen.
