It will work on grout, because it is very porous, and if the tile is very porous, then it might work on it as well. But if it's polished or very dense stone, then it may not be porous enough for this sealer to penetrate. Test it out on piece of excess tile. If it absorbs, then you are good to go. If it beads up and sits there for 10+ minutes, then it probably won't work. If non porous, then use a topical sealer like our AFM Mexeseal or AFM Watershield.
