"The grout itself is good and easy to mix and apply, but the final colour is much darker than I expected. Going by the colour shown on the image of the packet on the website, I thought this would be a medium shade of grey. However after applying and letting it dry I found it was very dark, almost black.
I would advise mixing a small amount of the grout first and letting it dry to see if its the colour you want. Otherwise, like me, you'll be stuck with very dark grout that is too much effort to remove!"
