    • Be sure to follow the directions on the specific two part epoxy product you’re using.

    • Mix the two-part epoxy on a piece of cardboard or a disposable plate.

    • Use a toothpick to mix the epoxy for at least 20 seconds.

    • After the epoxy is mixed, be ready to use it immediately, as it will quickly thicken and harden. Oftentimes you will have between 5 -10 minutes of working time before the epoxy is too thick and hard to use.
