Using an air compressor, pneumatic cutting tools, and a heavy-duty plastic template, images and designs, such as patterned borders, room motif accents, emblems, and logos can be precisely and efficiently engraved into concrete. Decorative concrete engraving becomes a permanent and elegant part of the concrete surface and at only a depth of about 1/16" does not present a trip or safety hazard. Individual elements of an image or design may colored through acid-staining and/or concrete dyes and water-based acrylic stains, either before or after the engraving process. Images and designs may be chosen from a preset catalog, or they may be converted from any electronic or computer image file. In the photo below, the sketch of a design on a jewelry case was reproduced on the main floor of an Irish pub in Farmington, Michigan, as a room motif accent.
