Newman's overlay demo started with a ¼-inch-thick self-leveling, tan-colored overlay cement. Using a tinted liquid release, he then textured the entire surface with a textured mat and stamped a border around the perimeter of his work with a grapevine pattern. The border area was separated from the rest of the slab by hand stamping a “hammered edge” pattern line. The following day he used an angle grinder with a diamond blade to saw an additional line on the outside of the grapevine pattern.
In the center of the panel he applied an adhesive stencil with an ornate pattern cut into it. This became the mask for a sprayed application of a polymer cement microfinish with a high-volume, low-pressure air sprayer (HVLP). He colored the finished work with several chemical stain colors, which were brush-applied while the stencil was still in place. An application of solvent-based acrylic sealer completed the work.
