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

We used these to bullnose our own porcelain tile. Worked well and much less expensive than buying factory bullnose.

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

This product works great. I had to cut the edge of my granite countertop then used this item to polish the cut side. WARNING: DO NOT USE THIS ON A STANDARD ANGLE GRINDER - THE PADS WILL DISINTEGRATE DUE TO THE HIGH SPEED. Use a variable speed angle grinder on medium speed OR an automotive buffer that has variable speed. I used the buffer, and it fit perfectly and worked great.

I am not sure why people do not read the directions listed and not exceed the limits of the pad with excessive RPM speeds. I used this on about 60sf of concrete countertop. I used a Harbor Freight polisher with digital readout and maintained 3000 RPM with 50 Grit, 100 Grit and finished with 200 Grit. If you let the polisher do the work and keep the pad level you cannot even notice any wear on the pad. I even swapped it for the second new pad and could not tell a difference. I am very impressed with these pads and would purchase again, but I think these will last a long time. You can dry polish up to 200 Grit and it suggest wet for 400 and up. My countertop is feels glass smooth so I did not see a reason to polish higher grit.

I used these to polish our marble shower floor. I wanted a tumbled finish so these worked great taking the etching out and leaving a great finish.

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.

These worked as advertised. There are best used with a buffer. Since they are 4 diameter, use with a drill is difficult to get even material removal and polishing.

You need to write down which are the finest grit to the course ones. The numbers wear off and each of these type of products have different color codes. No paperwork to help with this either.

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.

Backing pad was missing. Probably due to the box being ripped open and the sanding disk all out in the package
