Randy Meredith, Perfection Plus, Kernersville, N.C., started his career 25 years ago by starting a janitorial business, helping companies work out maintenance schedules among other things. Five years ago, he started a new company along with a partner, Chris Bullock, who had seven years of experience with decorative concrete. They decided to focus on diamond polishing floors, often adding dye coloring or patterning work with the use of stencils. They provide both decorative and nondecorative diamond polishing work and currently are working on a 70,000-square-foot warehouse floor.

At the Artistry Demos, they are planning to diamond polish their slab, stencil a pattern, and color it with both translucent and nontranslucent dyes.
