Diamond Polishing Pads 4 inch Wet/Dry Set of 11+1 Backer Pad by POLISHSURF

For small areas or tight spaces where a 4 1/2" grinder is needed, this is a fantastic set to have on hand. I just polished a 30SF area of terrazzo starting with the 50 grit and worked my way up to the 1500 grit, and the polishing pads held up very well and the pack can easily handle a 100-150SF area.

The kit comes with more of the lower grits as those are the ones that do the majority of the work, and the higher grits only have 1 disc each. I had zero issues with the discs getting clogged, and occasionally tapping the discs on the ground knocks out any dust collecting in between the teeth.

The discs remain cool even with heavy polishing, and that allows the discs to be durable and long lasting. The main backer pad screws on and holds tight until one is ready to remove it, and the pads are easy to change out as the velcro holds on strong but will release with some effort.

I'm really satisfied with the kit as it took out some heavy stains and it left the floor nicely polished with a very nice shine. A great kit and most definitely a very good value for the very reasonable price.

Worked good on mineral pool stains from pool water constantly dropping. Removed dark mineral build up on both tiles and plaster. Nice kit. Good adhesion to the backing pad. Will keep using.

WARNING! Comply with instructions that you cannot use with grinder that exceeds 5000 rpm. I did not read this and used a regular high rpm angle grinder and was injured in the side of my he head and inner thigh. A piece of a polishing pad broke off and hit the right temple of my head causing a lump and bruise. Additionally, a pad flew off at high speed at hit me in the groin area leaving a raised bump and large bruise. Lastly, the rubber pad that holds the different grit pads separated at high speed from the nut that screws onto the angle grinder at flew up into the ceiling and bounced off down into the wall both leaving black skid marks. Probably works well though with an adjustable, lower speed, angle grinder.

I ordered the discs to smooth out a concrete counter and bar top.

I was my first attempt and it had to be pored in place so the surface was far from perfect. The results really surprised me. I never thought it would come out so smooth. I spent about four hours with an electric buffer at about 3000 to 3800 rpms going through each grit of disc according to directions and online videos. Then I sealed the concrete with one coat of sealer. I am very pleased with the results. The product works exactly as described but it takes time and patience. I did about 25 square feet in about 4 hours taking frequent breaks and making sure to use plenty of water with the discs. The only ChangE the company could make would be to include one more 400 grit disc. As you can see in the third picture the 200 and 400 discs wore out the most. This may have been my lack of experience. But I still would have like an extra 400. Overall, I highly recommend this product. My wife is very happy with our new outdoor kitchen counter and bar top.

Great value for polishing almost all types of stone and concrete. Easy to use, just attach backer to a drill or polisher, and start with heaviest grit, working down to finest grit for a glass like result or stop when desired sheen is achieved. For best results and prevention of overheating materials and the pads, use cool cool water. Be prepared to clean area after using unless you have a shield around the pads, they will throw out the water and dust that's part of the polishing process, with that in mind, you can polish out scratches in stone counter tops, polish concrete sections, or for what ever your stone and concrete polishing needs are.

I believed what was stated in the product description, "Your surface will have a shiny gloss at the end of the polishing process, giving you an incredible sense of satisfaction." As you can see from my test piece of granite it does not.

The photo shows a test on a piece of black galaxy granite beginning with factory polished granite. Look outside the whiteout marked areas for what it looked like before anything was done to it. The left area is another test and unrelated to this product. The center area in the photo is what it looks like after using 400, 800 then the highest grit in this kit: 1500 . The 400 was used for about 15-20 seconds with water @ 1500 rpm increasing to 2000 for another 15-20 seconds. The 800 for about 5 MINUTES with water at 2500rpm increasing to 3000 for another 5 without noticeable difference in appearance. The 1500 pad was used at 3000, then 3500rpm for a long-long time with water and also allowing the water to evaporate for short periods before re-wetting in attempting to get anywhere close to the original appearance of the factory granite. It was unachievable after 20 minutes in just this tiny test area. The area to the right shows the result of one piece of 3000 grit silicone carbide wet and dry sandpaper with water after 3-5 minutes with water @ 3000rpm.

I'm returning the kit.

These pads are awesome so far. Used a 200 grout one to polish edges on a backsplash I set this week and it didn't even come close to wearing out, and left the tiles looking awesome in basically no time. They seem very durable and they do a great job.

I was really not expecting great performance for so ship pads. I'm a former stone fabricator and in my time diamond pads cost a fortune. Looks like thing have changed.

I bought these ones just for a small home project and they did the job.

They are excellent pads for a very good price.

I for sure recommend it
