Hello everyone!
To match our rather dark 60x60cm (24x24 inches) tiles, we had our bathroom grouted in black.
At first, all the grout lines were nicely black.
However, after some time, some of the grout lines have started turning white.
For example, when they get wet in the shower, the grout turns black again.
When they dry out, they turn white once more.
This effect is consistently reproducible.
What can we do to fix this?
As far as I remember, pre-mixed grout from a bag was used for grouting.
