So, I grouted my stepping stone and it looks so dull. The square tiles around the edge are still pretty shiny though. I liked it better before it was grouted. It's hard to tell from the picture, but it's not as shiny as it was before. Is there something I can put on the tiles to make them shiny again? I was thinking the grout is not quite right either, but if I darken it the grapes might not show up. Any suggestions would be appreciated!!!!
