Most floors were splotchy and unnatural with peeling protective finishes and waxes that made them worse. Urethane and epoxy sealers were discolored from trapped moisture. Acrylics were scratched, flaky, and in need of maintenance fairly often. Polished concrete became a new and efficient way of creating a natural shine and seal without any toxic, high-maintenance sealers. We use the same technology that was applied to granite and other natural stones for years. We combine the looks of traditional acid staining and diamond polishing for beautiful color and greater longevity.
