Weha 4 inch Donkey Quartz Face Polish Surface Polishing Pads This is the Weha 4 inch Donkey Quartz Face Polish Surface Polishing Pad - 1000 Grit and this is just what you need. The Weha "Donkey" Pads are 4" H&L backed Quartz Face, surface polishing pads designed specifically to repair the surface of quartz, engineered stone polishing pads. These amazing pads will blend the texture of the polish to make it match perfectly with the rest of the top. They are outstanding for quartz scratch repair, blending seams, even polishing edges. While these pads will not remove a deep scratch in quartz-based engineered stone, once you have removed the scratch these pads work double-duty bringing back the color, the gloss, and the texture. The Weha Donkey pads also work incredibly well on repairing marble etch-marks, and resurfacing marble counters for repair. This is a diamond sponge system that holds a lot of water. Count on amazing results when doing repair work inside a home where water is limited. Another fine product from an industry leader and innovator!
