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. ☹️

For the price performance is good. Dry pads almost always leave a bit to be desired, but I was impressed at the level of performance given the price. We will see how long they last...

Ive only used a few of the discs and they are very nice. Easy to change out being Velcro fastened and they stay secured in place

What can I say. They do the job right.

I used this product on a lot of different types of natural stones and it works great . I will buy this product again.

Although the product does not mention this, I used these with a standard orbital sander and they worked quite well - just takes more time and elbow grease than the more expensive water fed polisher. The velcro back of the pad stuck right to the orbital sander and I sponged water on the concrete surface. Need to apply a fair amount of pressure to the sander. This is one of the methods recommended by Cheng and these pads are cheaper than the ones he sells on his site.

Warning, do not use these pads on white or light colored stone, as they will burn and leave marks. I tried them wet and dry. I did find them to work just fine on darker stone. (Must have a variable speed grinder. Do not exceed recommended speed) Last substantially longer than PVA pads

I am installing granite tile in my kitchen. The edges need to be polished and it would have cost me $20 per edge to have it done. The tiles were only $4.00 each! So I looked on YouTube to see if I could polish them myself. It was recommended to get this set of polishing pads and a variable speed grinder. I ordered the Kawasaki grinder on Amazon, too. I clamped the tile onto my wood deck railing using the plastic ratchet clamps. Then I did as the video instructed, starting with the lowest number of polishing pad. I made 3 passes with each number of pad - and voila! The edge is just as smooth and shiny as the surface. The Velcro makes it fast and easy to change the pads and the grinder is easy to use. There is a lot of vibration, which shook me from head to toe, but not an unpleasant feeling. It is fun to do and very rewarding to see the results. The grinder and pads saved me a ton of money!

I was able to finish all of my granite countertop with these pads. You will not be able to get the granite back to the factory polished finish with this item but I had several people come through my kitchen and did not notice the difference.

These were great and did the job for a fraction of the price of having it done at a custom shop. I just ran a low water trickle when using the 400+grit. Takes a little while to do but so worth the effort for all that $ savings. Make sure to keep a low RPM on the polisher and the pads stay on the polishing disk/attachment without flying off. However do wear all the necessary eye/nose/etc. protection!
