Usage depends on the product type. Craft metallic sprays are intended for surfaces like drywall, concrete, masonry, glass, wood, vinyl and metal. Edible gold paints are formulated for food surfaces such as fondant, chilled buttercream, royal icing, sugar cookies, marshmallows, chocolate, ganache and modeling chocolate.
Gold leaf paints create a rich, shiny, reflective metallic or shimmery gold finish. Some products include real metal leafing flakes for an especially brilliant, reflective look, and user feedback commonly describes the result as shimmery gold.
Shake or stir the product before use, then pour and paint. Edible gold paint can be applied with brushes or sponges (a sable brush is often recommended). After use, wash brushes and tools with hot, soapy water.
Edible gold paints are formulated from ingredients that are safe to consume and are sold as ready-to-use gel food paints. Some product listings also state they do not contain the nine major allergens.
Coverage varies by product. One listing mentions up to about 12 sq ft, while another lists a maximum of around 20 sq ft—check the product label for the exact coverage for the specific can or bottle.
It depends on the formulation. Some gold leaf/metallic paints are rated for both interior and exterior use, while others—especially certain metallic sprays—are intended for indoor use only. Verify the intended use on the product label before applying.
