Diamond Polishing Pads 4 Inch Wet Dry Set 7 Pieces for Concrete Marble Quartz Stone Countertop Granite Polishing - by POLISHSURF

Great product for edge pilishing marble tiles. Doing a job that requires the marble tiles (12x12) to heave a finished edge and these worked fantastic. Key is to follow the directions and take your time and you will have a perfect factory polished edge. Highly recommend this product. Price is very reasonable also.

Recently you asked me to write/video/photo review for the product, at the time I only had the product for less than 24 hrs, I am learning how to use it and it is a superior product. I bought one for my son for his birthday and he liked it, so I bought one for myself. Next time please wait until I had time to understand the product before asking for a review. Thank You Very Kindly.

These work great. The arbor is lightweight but good for the price. The polishing pads can fly off, so use a face shield and protect your throat with a heavy coat or wrap. The pads adhere with velcro to the arbor, but pressure during work can destabilize them. This is not a design flaw. It is a factor of normal use. Make sure there is nobody within range of a flying disc. The discs are soft, yet their abrasive side can cause a scrape. I hope hearing this from me will help you avoid finding out about it with experience. Apply the pad to the arbor with even strong pressure.

Had to cut and polish a couple of granite side splash's in kitchen as we added a tile backsplash. Product put a nice shine on the cut ends. Worked well, just make sure you have the pads affixed to arbor. Didn't pay attention first time I put a pad on and sent the pad flying across the room

Used it on granite unfinished side for bathroom since I swapped the countertop around and exposed unfinished side. Had to start at beginning and used them all but worked wonderfully with grinder. Make sure to have a spray bottle to squirt on granite. Will probably never use them again but was fun to see the results.

My older grinder didn't accept the attachment wheel provided, because the standards have changed over the years. So I bought a new grinder (the cheapest at Lowe's), but it was not a variable speed. The first attempt at firing it up to polish my concrete hearth could have been DISASTROUS. The Velcro (hook and loop) polishing disc went flying off at full speed immediately, came within an inch of hitting my flat screen TV above the hearth, and dented my ceiling. It wasn't a big deal, but if it had flown in another direction and hit one of my kids in the face, it could have been really bad. It was moving FAST. I didn't end up getting a variable speed, though. I cleared everyone else out of the room, pressed the pad much more firmly to make sure the hook and loop connection was strong, then proceeded by being very cautious about what direction the tool was pointed, and making sure it was flat on the surface of the concrete (not up in the air) when I turned it on. Of course, now I have a variable speed grinder after the project is finished. :-) But I intend to pour a concrete vanity countertop and use this same kit (I only used a couple of the discs) to give it a nice finish. So this time I'll have the proper tool.

it works but it is very sketchy because of the velcro. When I turn on the grinder the disc actually slips a little bit off kilter. If they changed it to a more secure method, I'd buy again, but this is seriously scary.

In our bathroom we were installing a frameless glass shower enclosure and when the workers took up the threshold metal there was erosion of the travertine underneath. It didn't budge with sandpaper so I got this kit. I have a variable-speed grinder and found attaching the Velcro-type base for the various grits which start at 50 and to to 1500. You need to start at the lowest speed and at about the 400 grit increase it. You also need to have water to keep the work from drying out. You'll see a slurry forming to let you know you're cutting. The 50 grit will load up so be prepared to keep the pad wet to minimize this. You don't need to push down, let the "diamonds" do what they do to cut. If it feels hot you're probably pushing too hard. I found that the 1500 grit did not really give a "shine" but more of a "sheen" and this was ok for my application. I'd say good value for money but if you're looking for a bright polish you'll need a higher grit.
