Mapei adesilex P9 alternative

[32alan]

I need a polymer modified cement based adhesive to go over waterproofing, wanted to get Mapei adesilex P9 tile adhesive (as advices to use on here) but having problems getting hold of it. Can anyone tell me of an alternative, which is as good. Thanks.

Thanks for your help Dave.
Found out there is a Tile Giant within distance. Does anyone know what I should be paying for a bag of Mapei P9 20kg seems to be variable online?
