Alpha® Rigid Backer Pads served to eliminate the wavy finish by keeping the Ceramica flat to the polished surface. Although not the best alternative compared to Twistouch Turbo for this application, fabricators and tile contractors use it with good results. Restoration workers find that the rigidness of the pad enables them to work in small areas such as corners or staircases. Large machine manufacturers recommend flexible diamond discs for use on their automatic edge polishing machines specifically for the bullnose application using the Alpha® Rigid Backer Pad. Hook and loop backed, like the flexible pads, they also accept Ceramica, Sandpaper, and Felt Wheels.

The Rigid Backer Pad reduces surface distortion and wavy results on straight edges. Available in 3”, 4” and 5” sizes, the Rigid Backer Pad is exclusive to Alpha Professional Tools®. It comes in the standard 5/8”-11 thread commonly found on most polishing tools today. Some metric sizes are available on request. Super rigid and flat, there is no other backer pad like this.
