Print Article10. Work the 150-grit until you get an even, consistent pattern. You will have to blow the area with air to examine it. You may also want to bevel the rim slightly with the 150 grit. If you do this, be careful not scratch the top surface. Another method would be to profile the sink rim with a round-over bit. This should be used right after the 150 grit so you can polish the profile at the same time you polish the sink rim.
11. Once the 150-grit is complete, perform the same process with the 200 grit and then the successive grits. Make sure to use plenty of water and examine your work after each grit has run.
12. Once you have finished with the 3,000 grit, attach a black or white buff pad to the polisher. The black pad is used for dark granites and the white pad is used for light granites. For engineered stone, stop at the 3,000 grit. Do not use the buff pads on engineered stone.
13. Add water to the surface to be worked on. Work the buff pad the same way you did the other grits with the exception of adding no water as you work. In other words, you want to work the buff pad till it is dry.
