Porcelanosa mosaics..

[Stocks Tiles]

OK so I'm currently doing a large job and one of the shower trays covers around 3sqm and they have chosen a mosaic tile from Porcelanosa. The tile is branded Noohn mosaics, paradise tinybroken edge gris. I laid these yesterday morning as per instructions that came in the box and grouted this afternoon as instructs to give 24 hours, clean water used and no mess whilst laying and i have grouted with a titanium coloured grout. They have come up terrible, I'm hoping someone may have experienced anything with this tile?! I have taken a picture of a fresh sheet next to the laid and grouted ones, now of course the customer is going to be expecting the colour they are in the box! Certain sheets seem to have gone a sandy colour, I'm hoping that when I go back on Monday that they have all gone to one colour but I'm not holding out hope.

If I've done as per instructions say, who would be at fault if they end up patchy? They looked OK whilst laying them (off cuts of patchy sheets I have kept to one side now to show I didn't originally fix a off coloured sheet), washed them as I laid with clean water and now they've been grouted and washed 3 times as instructed they look terrible!

Help lol

It might be moisture, give them a few days to see if they change colour again.
Failing that get the rep out.

seems, another tonality. 🙁

try wetting a new sheet and see how dark it goes. Some of the stones look darker on the dry sheet. Like Stef says could just be moisture.

Sealed before grout?

Thanks for the replies, I will see how it goes over the weekend and have a look on Monday and hope it's moisture :/

No they were not sealed because the instructions didn't state to do so, just said to not use black or anthracite coloured grout on them - the instructions were step by step from preparing to grouting and cleaning off. The grout I used is a close match to the tile itself so I wasn't worried about staining them with the grout and I didn't leave it on for too long either. It's the going a sandy colour on some sheets that has concerned me and I really hope that it's just moisture as I've never had a problem with a stone material before and I'd hate to be having one now!

Thank you again

If you squint your eyes a bit you can see what appear to be two tiles on the left side that are differnt colour... rogue tiles or different batch?

It's stone mosaics .until they worn in a bit they will look different .no stone mosaics all coming from the same piece of stone .seal it .and tell them to let it wear in
