...I tried to talk my wife out of it, but she had to have the light coloured grouting. Anyway the inevitable has happened on our kitchen floor after 6 months and the grouting is looking pretty grubby! I know there are products out there but, I want to make sure I dont I damage/erode the sealing/protection (FZ Lithofin protective Impregnator W) which I applied the porcelain tile (and the grouting!). The tiler did a great job, but I wasnt convinced about his decision to use wide (flexi) grouting-I imagine the finer finer/smoother stuff would have been more resistant to grime build-up! Any advice would be welcome.
