Hello,
We had our kitchen fitted in the summer and had white tiles fitted with light grey grout. We didn't get the wall at the end of the worktop tiled but then changed our minds. We could never get back in touch with the original tiler, but we've just been having our bathroom done so got that tiler to do the little bit of tiling at the end instead. The grout has gone on really dark, which he has assured me will lighten in colour, but it's nearly 24 hours later and it still looks loads darker than the rest of the kitchen tiles. Does anyone have any advice - is it worth waiting out a couple more days (as it's cold and prob taking longer to dry fully) or would you say it should have lightened by now, in which case is the only solution getting him back to regrout? Wishing we hadn't dithered over it back in summer!
