Align and apply the emulsion or adhesive side of the photoresist to the substrate for the correct position for sandcarving. Most photoresist, including dry-processing photoresist, has a built-in adhesive that easily sticks to glass, crystal, marble, ceramic, acrylic, metal, and numerous other substrates. However, if sandcarving a porous substrate such as stone or some types of wood, apply a thin layer or two of sandcarvable adhesive to the stone prior to applying the photoresist film. Once photoresist is applied, remove the carrier sheet from the photoresist by flicking a corner with your fingernail or attach a small piece of tape to the corner of the photoresist and peel in one quick motion.
