Cooper started his contracting business 10 years ago, adding diamond polishing to his list of decorative techniques about 2 years ago. He positions his company as technical and creative—doing what the average contractor can't. He saw the Artistry Demo as an opportunity to experiment with new ideas in materials and methods. He divided his 10x10-foot slab in half, polishing one side about 1/16 inch deeper than the other to expose aggregate in the concrete. After diamond polishing the concrete to a 3000-grit finish, he applied self-adhesive and liquid-resist stencils to achieve both positive and negative images. He did a light sand-blasted profile through stencils at one location to show the effect of sand-blast profiling on polished concrete, and stenciled patterning on the rest of it, using an earth-colored chemical stain formulated for use over polished concrete. The finished work made it easy to imagine the possibilities.
