Epoxy, or cast resin plastic, is a clear liquid solution that hardens into a firm, clear plastic. Available in large quantities at most craft or hobby stores, resin will preserve any items cast inside it, making it a great way to give an old countertop a new surface and a new look. Create a new resin countertop incorporating any images or items, colours or textures you want to go with the decor of your kitchen.
Thoroughly wash and dry the countertops to remove any traces of dirt and debris that you won't want to get set into the epoxy.
Tape two 1-inch thick strips of cardboard along the edges of the counterop with masking tape, creating a lip to keep liquid resin from running over the edge. Apply the tape on the edge and bottom of the counter, keeping it off the top of the counter. Cover the exposed cardboard with masking tape to make it a more non-porous surface.
Coat the inside of the cardboard strips with vegetable oil. Smear it in place with your finger, and avoid getting any oil on the countertops themselves.
Prepare the countertops with any paint or flat, decorative items you may want beneath the resin layer. Use acrylic paint if you are painting. If you want to decorate the counter with flat paper items or photos, glue these in place using a découpage medium. Spread it both below and on top of the image. You might also glue some small or flat objects in place, such as small fresh or dried flowers, or coins. Let it dry.
Mix the epoxy in a large, disposable container. Make a quarter cup of mixed resin for each 6-inch square area of countertop you want to cover.
Add the glitter to the epoxy and stir thoroughly. Use as much or as little as you want. Use less if you want to be able to see through the epoxy to the countertop.
Pour the resin over the countertops. Use a spoon to dish the resin out of the bowl, but let it flow and spread out by itself without touching it; this will give it the smoothest and most consistent surface.
Let the resin air-dry according to the manufacturer's instructions. If your kitchen area is dusty, run area fans to blow air across the top of the counter to keep dust particles from settling in the liquid. This also will help the resin to dry faster.
