The make-up of the stone we refer to as "granite" is tremendously varied. Some granite is much more porous than others. Some granite needs to be sealed pretty often and some never needs sealing. Some is very stable and some is so full of fissures and veins that it needs netting epoxied to the back to keep it from breaking. Personally, I would not use a granite that is easy to stain on floors.

After I had Kashmir White granite counter tops installed in my kitchen, I learned that Kashmir White is not a true granite and that is one of the two most porous granites. Some websites statements as to porousness were alarming. Fortunately, I learned about Stonetech Bulletproof Sealer (DuPont), and it has really given me peace of mind (I seal granite every year). Nevertheless, had I been forewarned, I would have selected a different granite. I would not use Kashmir White granite for floor.

Thanks for the heads-up.

I repeated the experiment with a sample of Blanco Romano, and the overnight application of red wine wiped right off. The sample is slab thickness, like the sea foam green. Some thought that slab vs tile thickness has something to do with it, but I think what you said makes more sense.

The kashmir white soaked the wine right up. I wonder if Kashmir gold is also not a true granite. I have a sample of that (but I'm out of red wine).

Kashmir Gold soaked up the red wine stain just as readily as the Kashmir White.

I ended up getting grey sardo for flooring. Can't find too much info on it on the web. I found that it does spot, but gets hidden in the patteen. Does this mean it needs to be sealed?

I was told darker granite is usually denser than lighter. We used Labrador Antique for perimeter of kitchen, and a lovely piece of Giallo Beach for the center island.

We chose the piece of GB because of the beauty of the pattern, the almost crystal-like formations running through the slab. We knew it wouldn't take the beating my perimeter workspaces would; it hasn't held up perfectly - a little chipping - but it's absolutely gorgeous.

As for Lab Antique, I haven't found anything that CAN harm it so far! It's one of the hardest, highest density granites I've ever seen, and yet I still chose the tightest slabs I could find. (I'm suck a sucker for those blue and purple glittery spots, tho - easily my favorite granite in the world!)

Good luck!
