  • Tip

    Try to pop any air bubbles in the hot glue by pushing the hot glue down with the tip of the hot glue gun.

  • Step 3

    Let the glue dry until almost set (the center should still be soft and wet). Carefully place the LED (light first) into the center of the mold. The back of the light should be flush with the hot glue and not sunken in.

  • Tip

    The hot glue will set at different temperatures depending on the depth of your mold and the kind of hot glue you are using. Be patient - if the mold is very deep, it will take longer for the hot glue to set.

  • Step 4

    Let the hot glue dry completely until the mold feels cool to the touch. Then, carefully pop your molded piece out of the silicone mold.
