The Concria sleeking system has recently been released in the United States. It allows you to polish a new or existing surfaces without the use of heavy grinding machines. Using a six-step process, Concria discs are strong enough to expose “salt and pepper” and polish up to the equivalent of a 3,000-grit floor, leaving a glossy and hard, easy to clean, and durable surface.
The Concria discs, which snap onto standard brown stripping pads about a dozen at a time, are 3 inches (7.6 centimeters) in diameter and 10 millimeters thick. The diamonds for both grinding and polishing are bonded with a rigid resin. The strong resin helps increase the longevity of the discs.
