primer peeling

[Ajax123]

Well done Chequers for keeping your cool and doing this job properly, most would say damn it we've started it'll be alright!!.

These screeds are causing so many people problems, which is a real shame as they are so nice to work on. I've been recommending them to builders and so far have had no problems, i've been sanding and priming them with a dilute epoxy epoxy primer and that stuff doesn't shift, but i'm waiting now for someone to say you can't use that because it contains some new ..ide chemical that will react with it.
I will be swapping to the gypsum based adhesives on the next jobs as this is the direction that these floors dictate.
Once again Ajax has been an amazing help, with well thought out and well written guidance on these matters, he's being a bit of a hero on hero on here.
Good luck matey!

No pressure there then....

Sorry I mised your posts at the weekend. For future reference I think you would have been better to use a sot blasting machine to remove theprimer. Would have been much quicker and cleaner. However that bit sounds likeit is done now.
I guess the advent of primer less systems to go on anhydrite is a real bonus when you see stories like this.

What you doing regarding restocking the tiles. If it were me I wold deffo go with a primerless adhesive.

I’ve had a similar problem. I levelled my hallway using no nonsense floor screed. Then I primed it Bostik Cempolay Universal Primer Blue Pigment 2.5Ltr to get it ready for tilling but in a few areas, the primer has peeled off?
