Patchy uneven grout? - TilersForums.com

[Dave]

What’s weird is we’ve just wiped over with a dry towel, and the dark bits are turning a light grey? It’s definitely dried and set as well. Any ideas?

Is the colour of the powder ( grout) the same as the lighter section of grouted part.

The first picture is the colour of the powder and the second and third picture is the overall look of the tiles/grout. As you can see, there’s quite a lot of haze, could that have settled on top of some of the grout lines causing the unevenness in colour as we haven’t done a 2nd wash yet? Thank you for all your help btw! Really appreciate it.

Try washing down till clean , striking with the joints to remove residue. See how that dries.
