Ye i know you sealed them but if you grouted too early without giving sufficient time for the sealer to fully dry , you can simply wash off the sealer. Hence why they darken when you wet them.

I followed sealer instructions and waited 3 days before grouting. Hopefully Mapei stuff I’ve ordered does the trick

Used the Mapei stuff a few times and it’s made a difference. It’s the best it’s going to get I reckon. With the stones having the smallest of hairline natural cracks in them etc I’m never going to get to them. I’m happy with the outcome 👍🏻
