Review on OCR Concrete Diamond Grinding Grinder by Greg Sullivan

This grinder worked great. It's well built, durable and for the price you can't beat it! I used it to wipe off about 60 square feet of paint from my laundry room floor and another 30 square feet of mastic residue from a linoleum tile I removed from the half bathroom next to the laundry room. It took about 3 hours but now I have the perfect surface to put the grouted tile on. It made a huge mess, but that's because I used a 4.5 inch angle grinder and not a larger tool that can hold dust. I've tried working wet but I've found that it only works for a few seconds and then the area dries up and the dust is still flying in. I suggest using plenty of protective gear, especially a face mask, and isolating the area you're working in to keep the cloud of dust at bay. Also install fans to suck the dust out of the window if possible.
