Review on Sunjoyco Heavy Duty Diamond Cup Grinding Wheel - Ideal For Concrete, Marble, Granite And Masonry by Randy Basque

Using to remove old epoxy paint from concrete patio floor prior to installing ceramic tile. It works very well to do that. Fast paint removal, with not too much effort. So far I have removed about 300 square feet, and I cannot believe it is still sharp, and removing the paint down to the concrete the same as it did when I first started, leaving a clean smooth concrete surface. I'm also noticing that there doesn't seem to be much difference in the thickness of the blades since I started, it's not wearing down! Love it.
