Diamond Polishing Pads 4 inch Wet/Dry Set of 11+1 Backer Pad Best Value Granite Concrete

Needed to refinish a small slab of Carrara marble, a relatively soft stone. I bought these pads after reading all the reviews and thinking I wanted to splurge for a decent set of diamond polishing pads instead of the harbor freight polishing pads I had used previously with my angle grinder on edges only. This wax for the full surface, so I even bought a new polisher and made sure to keep the RPMs within the stated range. I tried it slower I tried it faster… with water, then dry, and I even went back and started over going from 200 grit up again, thinking maybe I had done something wrong, but none of my attempts gave me a factory finish! Its slightly shiny at best. I reverted to my non-diamond pads (only go up to 600 grit btw) and angle grinder and that worked even better than these at the finest grits! So I laid out more money and bought some marble polishing compound which Im expecting tomorrow. I hope it works to give me a factory finish. After spending five hours of working with these pads yesterday, Im really disappointed. ☹️

I purchased these for a recent kitchen project. I needed to cut and polish my quartz counter tops. This kit had grits from 50 up to 8000. The edges I cut and polished were just as good as the originally finished spots. Can’t tell. Another reviewer made a good point, most angle grinders are not variable speed, just on and off. I used an angle style automotive variable speed buffer since it has a 5/8” shank for the arbor pad. Set my garden hose for a constant trickle of water while polishing, and it worked great. If you don’t have a variable speed grinder or buffer, and it’s a small project, I’d recommend a 5/8” arbor adapter for a drill chuck.

I have used comparable products before and typically get very good wear out the pads using a wet polisher. These are the worst pads I have ever used. I am lucky I got the set with 2x 50, 100, and 200 but I will still need to order additional ones for this project. I am polishing a 12 square foot concrete counter top and used both 50 pads and Im not finished. I typically make more passes with this grit pad but was forced to go to the 100 because the pads wore out. I still have the edges to polish. I have also worn out one of the 100 pads on the top. I would typically be able to polish 3+ counter tops of this size with comparable pads. DO NOT BUY THESE PADS!!! I have never left a bad review as I am always generally happy with my purchases from Amazon. This is not one of them and would request my money back if I thought I would be able to get it returned. Again, these pads are horrible and do not buy them, purchase a different brand

Excellent starter kit, havent had a chance to use them a bunch but I played with some marble and they worked perfect.

I used these pads for the edges of marble tile for my counter top. The grittier pads (50 100 400) worked well however the fine grit pads ( 800 and up) gummed up and left black residue on the tile and pads. I had to repeatedly stop and use wd-40 to clean the pads and marble from the black residue. Im not sure if this is caused by a high rpm grinder or the fact that I was working on an edge as opposed to a flat surface. But, the sheen on the edge of the tiles now match the factory surface, so Im happy with the final product but the pads need to be thrown out.

Great products last a long time. I just threw away my first 200 grit from this kit last month. Im a general contractor that specializes in tile work, and I often need to grind or polish edges and 200 grit is my default for non shiney surfaces. Last a long time! Much cheaper than the local guys.

The Velcro came loose from the backing pad after approximately three hours of use, so I was annoyed about that. After I actually read the specs for the product I realized my grinder spins far too fast for these. Works great on an actual polisher. The polishing pads themselves seem fine, no complaints.

If you purchase a polisher or grinder that is capable of spinning at a low enough speed (2-3000 RPM) then you can get great results with these. We put in a granite tile counter top and had to polish the edges of all the perimeter tiles. It took some time to get proficient at polishing but eventually got great results! But be aware polishing stone, even with the right tools, is a very time consuming task requiring good attention to detail! We did it dry at 2000 RPM because adding water would have been much more hassle and mess. I think I can say with confidence that most of the bad reviews for this product are written by people who did not have a polisher or grinder with the correct RPM.

This product worked great for me. I decided to try a do it yourself project to polish the ends of some scrap granite pieces in order to create some small tables for my patio recliners. After doing some research on how to do the work I found a reasonable priced polisher and these polishing pad and went to work. I used the dry method of polishing. The project came out great and Im very pleased with this product. Even though polishing granite is a pretty slow process and takes a fair amount of effort Im glad I found this product and tried it myself.

Overall Im happy with the durability of these polishing pads, the shipping was really fast. However there needs to be an option to purchase a corser set like 30 grit, 50 grit, 100 grit, & 200 grit. We had to purchase lower grit pads from a different vendor to start polishing our concrete hearth pad. We never ended up using any of the pads finer than 200 grit.
