Grout

tenreds

Put new floor tiles down last week when I was grouting them the colour of grout blended in nicely with the tiles, but now it looks to light
Is there anything I can do, like say go over them again with a darker grout but I think I know the answer to that
Something I’m not prepared to do is rip out all the grout, thanks for any suggestions

It will darken naturally over time with dirt but maybe somewhat inconsistent in colour. Cementitious grout is absorbent so you could seal the tiles/grout while they're clean/consistent with a wet look sealer that should darken the grout depending on it's natural colour.
Going over again with a darker grout won't work as they're won't be enough depth for it to bind.
What grout and colour did you use.

TGS grout, it says light grey but it looks more like white, might try the sealer on a test patch and see how it looks, can you recommend any?
Thanks

Afraid not, I've only used Lithofin FZ Impregnator but that leaves an invisible seal so unlikely to affect your grout colour. You'd ideally need a gloss or wet look sealer but then you also need to be careful not to make the tiles slippery.
If you wet the grout at present does it transform to the desired colour, that would be the effect of the appropriate sealer.
