Tiling anthracite screed already primed

[stusgsx]

hi. Looked at a job this week anthracite screed it's been sanded and primed once but I like to use gypsom adhesive on these floors. Can I still use the gypsom adhesive over the primer?
Pretty sure i can but wanted to check as I worry enough about these screeds! Cheers

@Ajax123 uncle Alan is the screed king.

But @Dave has done a bunch too I think.

Good point not much good if it's just sat there ready to peel off. Will find out cheers

The customer has told me he used the primer recommended by screed company and diluted as per instructions

Most gypsum addyts recommend an acrylic primer. If its epoxy you can use either but cement is better over epoxy. Epoxy is quiutre an expensive way to go though. My own recommendation is acryliuc primer 1 coat diluted just to stabilise the surface then a gypsum based Addy.

you could prime over the primer?

Dont think it would be wise to prime acrylic over epoxy though
