Hello
We've just had the bathroom retiled - walls and floor. We have white grout on the walls and grey grout on the floor. The problem is that the grey grout changes to a much darker grey or black when it gets wet - which is quite often in a bathroom! This gives a rather uneven and dirty appearence which we'd like to avoid. I was wondering if it might be possible to seal the floor grout so that it didn't wet and darken so much. Would PVA do the trick or are there any specialised compounds for this?
Thanks for any advice Jeff
