This is my very first concrete counter-top that I made a week ago. I built the template out of 3 inch strips of 1/8 pine (to get the actual layout of the entire counter-top surface). I then built the forms out of melamine, and placed an edge mold inside the melamine edge to give this natural stone look. They’re 2″ thick and turned out beautifully. Now I have to polish, seal, and wax.
