Shower surround substrate

[STEvieXE]

When u say prime before hand whatever u do, I assume u mean the tanking primer?

The tape n addy joints don't need primed? As far as I am aware Hardie backer does not need primed?

Prime everything. Hardiebacker will definitely need priming despite what the instructions say. Let me guess- are you using the Mapei kit?

 

[STEvieXE]

Is it a decent one to use? I can get Mapei in my local screwfix which is handy to me.

How's that sound?

That’ll do the job just fine
