That's ultra grey, looks a bit dark cuz had only just given it a final seal, I actually took the time to mask every joint before grouting, quick tickle over with the sponge then removed masking tape and didn't touch it again. Saved a lot of wash up time and left joints nice and full

Ha, I would so mess that up. Did you seal the stone before grouting or do it all together at the end?

Sealed twice before grouting then once after. Soaks up sealer like a sponge
