1. If you’re starting from scratch you can purchase a 3-inch medium density fiberboard (MDF board) as your countertop. You’ll need paint and primer in one so we recommend picking up a can of Ethiopia from Behr.

2. Sand the edges and the countertop smoothly. Apply two coats of paint & primer in one. Let the countertop and edges fully dry before continuing. Then sand the edges and top with 220 grit.

9. Use your gloved hand to apply epoxy to the edges in long horizontal strokes and break up any surface tension. Use extra epoxy that dripped off the edges to fill in any holes or spaces. The epoxy will thin out on the edges but the copper spray paint will help the edges keep their color.

12. Meld the copper and hunter green spray paint together using your chop brush. Rub edges in between chopping. It will help even the epoxy and give a smooth overall finish. Use the torch/heat gun to eliminate air bubbles. You could use the torch less for a more dynamic, rocky look.

14. Torch your countertop one final time to remove any air incorporated into the epoxy while working on your project. Then let the countertop dry completely overnight and maybe into the afternoon.

Drying depends on the temperature and humidity of your room. The epoxy will begin to become tacky before hardening. Let the clear coat completely dry before use.
