What are the surfaces/substrates to which I may apply this product?

Promise’s Epoxy Resins are designed for use with a wide variety of surfaces including wood, metal, canvas, and plastics—if unsure test a small area of the application surface. Epoxy resins do not adhere well to certain plastics like disposable bags, tarps, and silicone molds—which makes these materials good for artisans to work with when creating their artwork.
