Pro Tips

Shake well, then spray a thin even mist over the inside of a clean dry mould and wipe away any excess so it does not pool, which keeps detail crisp. Let it settle for a moment before pouring your material. A light coat is enough; too much can leave a film on the finished piece. Use in a well ventilated area and reapply between casts as needed.

Complete Your Setup

Pair this spray with silicone and resin moulds, eco casting powder or epoxy resin, mixing cups and stir sticks, and a cast sealer for a finished, glossy surface. Keep a spare bottle for high volume casting sessions.
