Alpha® Sandpaper discs are waterproof, hook and loop backed sanding and polishing discs made with silicon carbide abrasive. They are designed for use on marble and other softer natural stones, supporting both wet and dry applications during fabrication, installation, and restoration.
The silicon carbide abrasive resists clogging when used wet, helping extend disc life while maintaining consistent cutting performance. Hook and loop backing allows for quick disc changes when used with standard backer pads or the Alpha® GV5000 backer pad.
