Using Silicone Molds Successfully

Silicone molds are popular for resin crafts—here’s how to get the best results:

Mold Prep:

  • Clean with isopropyl alcohol and allow to dry.

  • Apply mold release for longer mold life and easier demolding.

Preventing Dull Backs:

  • Use high-gloss molds or coat the surface with a clear resin layer post-demold.

Timing Demold:

  • Demold after full cure time for best results—resin too soft may warp.

Storage Tips:

  • Store molds flat and away from sunlight.

  • Clean after each use to prevent buildup.

Tips:

  • Avoid torching in the mold—it can damage the silicone.

  • Use a toothpick or stirring stick to pop microbubbles in corners.
