I still Polybond new plaster with watered down pva before tiling. Always have, always will. Who else does? Having an argument with a smart arse builder "who's been tiling for years" who says its not needed.
I've obviously had my head in the sand on this one after all these years! So why not PVA and what do you all use? Surely new plaster needs priming one way or another?
Yes plaster needs priming, but not with PVA, in any form.
Use a proper tiling primer like an SBR diluted as per instructions.
Better still, take guidance from the adhesive instructions that u intend to use.
That way if there is ever an issue then at least u've followed instructions.
Many primers are different colours, with that adhesive manufacturers can identify their products instantly.
So if u mix brands, they can walk away without responsibility.
