You will need to use a set of diamond polishing pads (usually 7 to 8 pcs) from 50 grit, 100 grit all the way to 3000 grit and buff to polish granite. You will also need a variable speed grinder/polisher. If you only need to polish one or two tiles, you may use the diamond hand polishing pads. There are a few videos on YouTube that shows how to polish. Please follow the link here: http://www.youtube.com/watch?v=Ak6XnQCRy1E
