Before getting to the fun part of this project we need to prep the coasters. Mask off the back of the coasters with your favorite brand of painter’s tape, making sure to firmly press down the edges. Crinkle aluminum foil and glue it to the wooden coaster, being careful to cut off any excess with a craft knife. Using painter’s tape, mask off the sides of the coasters to create a boundary for the epoxy.

Combine pigment powder, high flow acrylic or alcohol ink with Mas Epoxies Table Top Pro epoxy. Pour a small amount of your pigmented epoxy onto the crinkled foil and spread evenly, leaving some of the high ridges of the foil visible. Let this layer cure completely before removing the tape from the edges.

I used two different methods for sanding these coasters. We will start with the purple one. Using a palm sander, I sanded down the top of the coaster till it was completely smooth. This method will tear out most of the foil, leaving you with some large and small voids that will need to be filled in a later step. Make sure to use tweezers to pick out any loose foil shards. For the teal coaster, I just sanded the edges of the piece, making sure that there were no sharp spots. Clean off the coasters with rubbing alcohol and a soft rag before moving on to the next step.

We will start with the purple coaster. Using black pigmented epoxy, fill in all of the gaps, making sure that there are no large air pockets. Set this piece aside and let it fully cure while you pour a clear layer of epoxy over the teal coaster. The pieces must be fully cured before moving on to the next step.

Sand both the top and sides of the coasters until they are smooth and level. Clean the coasters with a soft rag and rubbing alcohol.

Using black acrylic paint, carefully paint the bottom half of the coaster to hide the wooden coaster base. Once the acrylic is dry, add the final layer of clear epoxy to seal everything in and create a beautiful shine.

Last but not least, let’s give the back of the coasters some love! Peel off all remaining painter’s tape and paint the back of the coaster black to match the edges. Adhere the adhesive cork backings and sign your name (I used a wood burning tool).
