4 Inch Diamond Polishing Pads with 5/8’’-11 Backer Pad, 12PCS Wet/Dry Granite Stone Polish Pad Kit for Drill, Grinder, Polisher, 50-6000 Grit Polishing Pad for Concrete Marble Rock Countertop Quartz

I poured some industrial looking concrete counter tops for an outdoor kitchen I built under a new covered patio. These actually did fine on a 5" DA sander. I started with 50 grit and went to 800 grit, all wet sanded. I stopped there because I wanted to leave the air bubble voids and the final finish was to be paint anyway. But there's little doubt they do the job - quickly cutting through and leveling the surface. I would suggest you take a photo or keep notes as to which color is which grit because the process of wet sanding washed away the grit size as printed on the under-side of the pads. Once the pads were dry I used as Sharpie to note the grit size for the next time I need to use them.

Works great, used it for terazzo refinish. 50-100 grit really chews down old terazzo. The high grit gets a good polish

These pads will get you 95% there for smoothing out scuffs and scratches in a granite counter top. But you will still need a high quality stone polishing paste or compound like MB-20 to attain a high gloss finish. I worked a worn and scratched area of a granite counter top with the 1500, then 3000, then 6000 pads. It left the stone surface with a very smooth but dull matte finish. I then applied MB-20 granite polish on one of the felt pads that came with this kit to achieve a very high gloss finish.

Nice kit for our crews to do client repairs thank you

Great product but wouldn't work on my current machine!

These pads work well for polishing marble and stone. Order came quickly and is a life saver for those who need to fabricate bullnose at the job

I love these they are excellent.

The finished product is very nice, but they really don't last, especially the lower grits. I fortunately had some "scraps" leftover from the first set of these, so I was able to complete the job with ordering a third set. They work well, but don't plan on getting through more than one small job.

鏡をダイヤモンド入りの水垢落としを使ったら傷だらけになりました。まったく見えない・・・ その後セリウム粉末を買ったが薄い小傷しか落ちないのでこの商品を買いました。 指や爪でわかるガラス傷はこの商品買った方が一瞬でツルツルになります。 水平に当てるのがコツです。斜めに研磨すると深い傷が入ります。細かいので削れば消えます。 400番→いろいろ試し最後6000番だったかなで指で触っても段差を感じないまでの擦り傷になりました。 最後はセリウムで研磨しました。セリウムの代わりは重曹１水１で練重曹を作ればセリウムと同じぐらいの研磨が出来るとかできないとか？聞きました。セリウムは化学研磨なのできれいになります。 最後セリウムで磨き綺麗に鏡が復活しました。

Muy utiles para areas pequeñas.

Fast delivery and excellent product for polishing fog light glass that is fine pitted from road dust & dirt

Not working properly, and poor quality. All pads seem the same grit number.

Worked beautifully. I used this on my granite countertops and it got rid of all of the water stains.
