Alpha® Ceramica Resin discs are the backbone of the polishing process. These high performance discs provide the best possible professional polish on the curved edges of granite. The polish obtained from using these discs is usually higher than the original factory polish. Fabricators achieve excellent results consistently and are unable to match the results with any other polishing system. Tile contractors are impressed by the variety of applications in which Alpha® Ceramica Resin discs can be used. The original Alpha® Ceramica Resin discs are available in 150, 300, 500, 1000, 2000, and 3000 grits. Alpha® Ceramica Resin discs are designed for wet granite polishing and work extremely well in tight curved areas such as inside sinkholes for undermount sinks.
