Paint the coasters with a few coats of paint. I painted the top, bottom, and sides for a finished look. Allow to dry and cure completely before continuing. Add strips of tape to the coasters in whichever directions you choose.
Protect your work surface, then break out the two-part epoxy. Mix a 1:1 ratio and follow the mixing instruction exactly.
Raise the coasters by setting them on something to ensure they do not stick to the surface they are on. Pour the epoxy onto the coasters.
After you have spread your epoxy, pop any bubbles by running a lighter over the surface but DO NOT touch the surface with the flame.
Allow the epoxy to cure for 24 hours before touching the project.
Add felt pads to the bottom of each coaster to protect your table if desired.
Your coasters are ready to use!
