I sealed the tiles with two clear coats before using a dark groat, which prevented the tiles, which are porous, from being discolored. I recommend two coats. Tile looks great - terrific product.
This piece is nice....colors are not as vibrant as I expected and do not pop as I thought they would --to add the umph!! to my kitchen remodel. One of the tiles had a corner crack that fell off ......tie restraints ......and it is small enough to disguise -- the cabinets are in and the tile is next to be set.......sooooooooo ???
