USER GUIDE: Dry Polishing pads for Granite, Concrete, Stone and Marble. 1
Safety first: ensure to wear safety protection. Put on your goggles and dust mask. Polishing stone or concrete creates dust, so ensure to protect your eyes and lungs. We offer vacuum dust covers available with the Rotoblast polisher, Model: M100K VAC. This mitigates dust and protects your lungs and working area.
Diamond dry polishing pads are used to polish granite, concrete, stone and marble. Diamonds are impregnated through the resin pad. 3
For polishing granite and concrete set the stone polisher to 2,800 RPM (speed 4 on the Rotoblast M100K) and attach the 50-grit grinding disk to the Velcro backer pad on the Rotoblast M100K stone polisher. For softer stone such as marble, RPM should be low approx. 1000-1500 RPM (speed 2 or 3 on Rotoblast M100K). Grind the surface in a circular motion to remove uneven spots. To increase longevity of pads, use little to no pressure on 50 and 100-grit disks. Purchase a medium grit metal Cup Wheel. This will increase the longevity of 50 and 100-grit disks when grinding.
Eliminate color transfer from pads by using soapy water. Ensure you are moving the pads in circular motion to dissipate heat from the surface and pads caused by friction. Increase pressure on pads for higher grits, however, do not allow stone to heat up. Stop often to allow the material to cool down caused by friction. 5
Change the disk to 100-grit. Grind surface again, moving in a circular motion. This should remove the majority of the remaining scratches. Follow this disk with the 200-grit one, which should remove larger scratches and leave a smoother surface. 6
Begin polishing by changing the grinding disk to a 400-grit one, which should finish removing light scratches. Increase pressure on the disks, however, do not allow stone or concrete to over heat. The surface of the stone should begin to look shiny. Continue with an 800-grit disk, a 1500-grit one, a 3000-grit one and a 8500-grit one known as a buff pad. 7
Pads are deigned in a hook and loop design. This allows Velcro on the backside to be attached to a backer pad available on The backer pad easily attaches with Velcro for use. 8
DO NOT use high speed grinders. High speed will destroy the pad and mitigate any polish. Always use a low speed variable grinder/polisher.
