OK I'm going to say it. You are a professional tiler yet you have never seen grey grout dry out before? You took a photo an hour after grouting and are having a fit because "IT'S DRYING"
You have to watch using grey grout on shower walls. There is waterproof which shouldn't change colour, then there is water resistant which will.Is that the same as when the grout goes slightly darker when it gets wet in a shower and the customer thinks there is something wrong with it?!! 🙂
