This is a Celtic cross design that a customer found in a magazine (left) and wanted reproduced on her basement floor. It was engraved into a 3/8" self-leveling Ardex SDT cement overlay using the Engrave-A-Crete concrete engraving tools. The wood grain and color of the cross were achieved with Kodiak Brown acid stain from QC Construction Products. The design on the cross, and the 'sun' in the background were colored with yellow 100% solids epoxy. The outline was filled with black tile grout. The surrounding cement overlay was then acid stained, and the floor was sealed with a water-based urethane sealer.
