As the final abrasive stage in granite polishing, this 3000 grit diamond pad is used to achieve a maximum, mirror-like shine. Its extremely fine diamond abrasive polishes the surface to a microscopic level, which creates deep color and high reflectivity. Used correctly, this pad produces a finish that meets or exceeds factory standards. It is designed for wet use with a variable-speed polisher and is the last step before optional buffing.
