Will resin stick to ceramic?
Just so, what material does epoxy resin not stick to?
Epoxy resin adhesives will bond all woods, aluminum and glass well. It does not bond to Teflon, polyethylene, polypropylene, nylon, or Mylar. It bonds poorly to polyvinyl chloride, acrylic and polycarbonate plastics. The only way to tell if an epoxy will bond to a material is to try it.
Simply so, will epoxy resin stick to ceramic tile?
If you are planning on using epoxy over ceramic tiles, or are doing mosaics with ceramic tiles, epoxy does not bond with them. This is because there is a finish put on ceramic tiles with which epoxy cannot bond. You can lightly sand the surface to remove the finish, and then epoxy can then properly adhere to the tiles.
Nonstick cooking spray, available in most any grocery store, works as a suitable resin mold release agent. It's nontoxic and won't harm the resin or the mold. Once you remove the resin creation from the mold, wipe the cooking spray off the resin and the mold using a rag.
