Gerald Taylor is the owner of Images in Concrete, LLC, where he specializes in concrete and granite engraving. This includes working in public art and site-specific residential. In this project he’s making a concrete fleur-de-lis table top that’s colored and polished. The 30″ dia. x 2″ depth table top has a fleur-de-lis design and a metallic rope edge.
I start by placing metal strips around the edge of the project. Using these strips I insert a rope edge form liner. The fleur-de-lis design is cut from 1/2″ styrofoam and placed in the casting. I glue the styrofoam design to the bottom of the mold and spray the mold using a release agent (one part castor oil/nine parts denatured alcohol.)
I then mix two 80 lb. bags of Quikrete with buff color and Walttools Tru-Pak mortar to increase strength. I mix to the consistency of pudding. After I place some of the concrete in the mold, I fill the other half and then vibrate. I used my Bosch hammer to vibrate the mold and it worked great.
A day later the casting is removed and the top is ground with 5″ grinder and a diamond cup wheel. I used my oscillating tool for delicate pinpoint sanding of the styrofoam pattern and to smooth curves in the design.
The rope edge is finished with a metallic copper paint and then sealed with a couple of coats of solvent acrylic. That’s how you create a custom decorative concrete table top people will notice for years, if not forever.
