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.

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.

Perfect for my day to day projects
