Granite floor tiles - do they nead sealing

[smicol]

I have 18" black "star galaxy" granite floor tiles. Should they be sealed - the supplier said don't bother, but I am not sure. If yes, what sealant should I use, and should it be done before or after grouting?

If the granite is in a high traffic area, say a kitchen floor then i would seal before and after grouting.

I have laid the very same tiles and I sealed them. lithofin Stainstop MN. I grouted afterwards.

In most cases they need sealing IMO. But my philosophy is to test test and test
