I had about 100sqM of Brett Paving Canterbury slabs in grey laid just over 2 years ago (https://www.brettpaving.co.uk/home-owne ... anterbury/) . I’ve pressure washed them a few times, all OK but they have faded to almost white. I’d like a sealant that darkens them. Just had a chap pressure wash them with a view to sealing, but the sealer he was going to use didn’t change the colour at all, so I told him I’d do it myself.

What’s the recommendation for cast concrete slabs, to darken them down? Happy with matt or gloss really, but preferably matt. We have woodland next door so I will need to pressure wash the slabs yearly, so any sealant will need to stand up to this.

Incidentally I used Jointex Easy Joint brush in mortar to point them with, and its stood up very well so far.

Thanks in advance.
