So, on Saturday 1/14/17, I had a mosaic glass & limestone backsplash installed in my bathroom. The tile is from Dal-Tile: Limestone Collection Gris et Blanc Rain Drop DA19.

I did some research and learned that it is important to seal the tile before installation so the grout will not stain the limestone. I sealed the tops of the tile with Miracle 511 Impregnator & Sealer. The sealing went fine, and the stones returned to their oiginal matte/chalky finish once dry, which is what I wanted.

The tile was installed and the grout used was Laticrete's Premium Pro Epoxy in color Platinum. The grout looks terrific, but the limestone now looks "enhanced". It is at least 2 shades darker than it should be. There is no "picture framing" effect. It's a solid darkening across every tile. The glass tiles appear to be unaffected.

I contacted Laticrete and they thought that it was perhaps caused by epoxy haze (I cannot see any haze on the tiles), and they suggested using StoneTech Klenzall to see if that would lift the haze/stain. I tried that last night, but the improvement was minimal to none.

I'm hoping that you might have some experience with how to fix this darkening of my tile. I looked for a poultice recipe for epoxy resin staining, but couldn't find anything.

I've attached a picture that shows what the tile should look like and and how it turned out.
