Alpha® Sandpaper resists clogging when used wet, thus extending the life of the disc. The discs can be used dry if necessary and are very durable. The hook and loop backing makes disc changes simple. Silicon Carbide is the abrasive of choice for sanding and polishing marble, travertine, terrazzo and onyx. Alpha® Sandpaper can also be used to polish glass, metal and wood. Used with our standard backer pads, our Twistouch backing system or the GV5000 backer pad, Alpha® Sandpaper is sure to give you the best results. For an extra high glossy finish, use the Alpha® Felt Wheel with a buffing compound to finish the polishing process.
