What Materials Can I Use Epoxy Resin On?

You can use ArtResin epoxy resin on a variety of materials including acrylics, watercolour, oil paint ( once it’s completely dry ), photographs, inkjet prints, spray paint, encaustics, inks, paper collage, wood, metal, wood, flowers and rocks. ArtResin adheres to almost every material with the exception of plastic, silicone, plexiglass, vinyl, wax paper and parchment paper. 

ArtResin will adhere to most materials except those designed to repel water.
  You can use this to your advantage, for example, by lining your work surface with a vinyl shower curtain, using plastic support stands to prop your work off of your surface, or by pouring ArtResin into silicone molds - the cured resin will peel out perfectly.

You may want to avoid pouring it over loose materials such as charcoal or chalk pastel - anything that is not completely adhered to the surface of your work could potentially mix into the liquid resin once it's poured and float around. Some lower quality papers can absorb resin rather than allowing it to sit on top, in which case a sealant should be used over the paper first to avoid seepage. Your best bet is always to test ArtResin before you work on your final project.
