Nice kit, ready to go
By Daniel A. Koblosh
My existing grinders all run about 10,000 RPM. This grinder is compact and runs at 4500 RPM (so it won't overrev the pads), and has a standard 5/8-11 grinder thread. Very light weight and comfortable. Comes with a guard, screw-in side handle and an extra set of brushes. Motor is not labeled. Can't use the guard when polishing, but it's there nonetheless.
Comes with seven, 4" diameter Velcro-backed polishing pads that attach to a supplied adapter that screws onto the grinder:
50 grit -- rough cut if surface is really rough
100 grit -- rough cut
200 grit -- start with this if surface is already smooth; will remove big scratches
400 grit -- removes small scratches
800 grit -- surface should shine after this pad
1500 grit -- using pads above 800 should be done after application of densifier (see below); surface should reflect now
3000 grit -- final finish. If done right, it says the stone should look wet.
There are three different adapters available, depending on the surface shape. Some are flexible, others are rigid. The adapter that came with the kit is sort of both -- semi-rigid.
Per the info sheet, all dry grinding steps should use a light, circular motion, like waxing a car with a buffer. New diamonds appear on the pads as they wear down.
Applying too much pressure will throw off diamonds before their useful life is over. Also, too much pressure will build up too much heat and melt the rock surface. Not good, apparently. One reason most polishing is done with water cooling.
More info at [...]
It says dry polishingis very aggressive and needs a light touch and under-5000 RPM speeds, unless (per instructions) polishing "softer limestone such as marble or travertine you'll need to run the pads at lower speed or add soapy water to the surface to avoid color transfer."
Will give it a try to edge polish a small granite slab after I cut the slab to size.
It also comes with two bags of powder. The larger bag is the "densifier." Per the included info sheet around 11 oz of this sugar-like powder is mixed with a quart of deionized or purified drinking water and becomes corrosive -- wear gloves and eye protection. It can be stored in a heavy duty polyethylene (PE) bottle. I assume you need to keep all metal away for long term storage. No metal jar caps.
The other smaller pouch of chalky powder is for filling pores and top curing. A gallon of solution is made up adding just a teaspoon of this powder to a gallon of tap water, letting the solution settle, and then using only the clear solution on top, adding more water as needed.
The densifier is squeegeed onto the surface and allowed to set overnight under a plastic cover so it won't dry out as it forms a gel. The plastic dropcloth keeps CO2 out during the process and to keep it damp. The gel bonds with the aggregates and hardens the surface so a higher sheen can be achieved.
The other solution is used to fill in gaps and will bond with the densifier.
Obviously, there's more to polishing granite than meets the eye.

Poor product, Terrible customer service!
By JC2
I do home remodeling and I order this because my polisher/profiler had broken down. I needed something for the moment so I looked on Amazon. I found this. I thought I was dealing with Amazon, but, I was just dealing with some third party. when I attempted to contact this person to return the item and switch it for a different one, he accuse me of not knowing how to use a polisher for one, then on a different e-mail he suggested that I use WD 40, a chemical on a countertop that was going to be used for food. at that point I knew what I was dealing with so I cut my losses. I'm writing this review to warn people of the third party seller at Amazon. they are shady!

Outdoor Kitchen with Granite Tiled Counter Top
We installed an outdoor kitchen with granite tile counter tops. We needed something to polish the edges of the counter top where the cuts may be exposed and or the edges may be exposed. This does the job. We were able to easily bring those cut edges to a fine polish the same as the factory polish. We were also able to round off the cut edges so they were not so sharp.
Excellent product for the money. I am not sure this device will hold up in an industrial setting. We spent the $100 bucks including shipping got the job done by ordering a second set of pads and put the thing in a closet to rest. THE END
Excellent Product - 1 granite tiled kitchen counter complete - wife loves it
PS: I am still not sure what to do with the white bag of powder shown in the picture. I am sure one day we will figure it out.
