Instructions

  • Slowly mix equal parts of the resin in a plastic disposable cup. Just a little to cover the bottom of the mold for 3 minutes with a popsicle stick.
  • Then let it sit for 2 minutes.
  • Pour half into one mold and the rest in the other.
  • Use a heat gun to remove any bubbles.
  • Let the resin slightly harden for about 2 hours.
  • Set the sea glass and the shells upside down gently on top of the resin.
  • Mix the remaining resin solutions together slowly for 3 minutes.
  • Allow the resin to sit in the cup to settle for 2 minutes.
  • Then gently pour the resin equally over the two molds prepared with shells.
  • Wait for at least 4 hours for the resin to harden before removing them from the molds.
  • Then let the resin coasters continue to cure for 24 hours.
  • If desired place rubber pads on the bottom for protection.
