This is a Celtic cross design our customer found in a magazine (photo above left) and wanted reproduced on her basement floor. After laying out the design, we used concrete engraving tools from the Engrave-A-Crete Company to engrave it into a 3/8" self-leveling cement overlay. The wood grain and main color of the cross were achieved with Kodiak Brown acid stain from QC Construction Products. The interior design on the cross and 'sun' in the background were colored with yellow 100% solids epoxy. The outline was filled with black tile grout. To protect the design, we then sealed it with a clear, water-based urethane sealer.
