Has all my Laitance been removed??

I use a 4:1 ratio and not had a single issue with bonding . Yes gypsum adhesive can be used to adhere the tiles but like i said , not sure schluter uk advise to use it with Ditra.

Is that 4 parts water to 1 part primer or the other way around? And do you use the same ratio for every coat? Thanks

Just to update I've hoovered the whole floor and I've noticed theres areas of lighter patches. Could this be laitance stuck to floor or is this normal?

If you are not sure sand it again? It's you that needs to be comfortable that its properly prepped. I can say there is some small, patches of what looks like flaky laitance there but whether its enough to cause you an issue I dont know from photos.

The only test I've done is laying a dpm on the floor with planks of wood on either side to weigh it down and checked if theres any condensation underneath 24 hrs later
