Sanding/Sharpening media and their respective grits

[Greg Ketell]

Hi all,

A few years back Larry Robertson from IAP started a list of different sanding media and the micron sizes used.

It helped me because I would sand with sandpaper, then use steel wool, then use micromesh, then polishing compounds and I found that I was going backwards in my process several times.

I've since added quite a bit to the list and thought I would make it available for others to use. Originally it was an Excel spreadsheet but now it is freely available on my Google Docs. If you are interested, you can see it here:

Please let me know if you have any more information that could be added to the list.

Hi Greg, i didn't see my two favorites on your list - cerium oxide and tin oxide, both can be had at 0.5 microns, these i only use for final sheening of french [friction] polishing which will bring up a nice liquid glass look once you find out how to apply it properly, mostly they are used for polishing up marble and other stone or for polishing lenses etc.
