Whether you've found a piece of granite stone and want to polish it or need to smooth out a larger piece of granite for a DIY project, the process requires a bit of physical labor.

Granite is a beautiful stone to have in your home.Granite is a beautiful stone to have in your home.
If you've purchased granite slabs to create countertops, chances are most of the granite will already be polished and ready to assemble. However, the edges tend to be rough and should be smoothed and polished for a more refined look.

Apply a course grit pad (50-150 grit) to the stone polisher and plug it in. To apply the pad, place it against the polisher. The velcro will allow the surfaces to stick to each other.

Turn the stone polisher on and press it against the rough natural stone granite. Move the polisher back and forth across the granite until it looks and feels polished. A few rough spots are okay at this stage.

Apply a grit pad in the 3000 to 5000 range (more refined) to the stone polisher and go over the polished area to smooth out any rough spots. Continue polishing until you've reached your desired level of smoothness.
