Anyone know how to tile on seraphite? Primer?

[Dave]

Is just i heard pva was for gypsum and acrylic was for cement based substrates. But I've now bought mapei plaster primer, doesn't say acrylic specifically, but I hope its the rights stuff.
Thanks for your responses... just spent loads on compression fitting for the hot and cold water, when that's done... tiling begins 🤯

Good look and let us know how you get on and say NO to PVA 😂
