Tiling quartz split face tiles to the wall - Tile Advice

[Tile_novice]

Hi guys,
Anyone had experience with quartz split face tiles to be used on a solid blockwork wall which has been rendered and painted previously, but I plan to score the surface for maximum adhesion. Any advice on what adhesive to use? Don't particularly want to go down the hardie board route for the wall - it will be a feature wall in a living room.
Thanks in advance.

You will need to make sure all the paint is removed first.
Then a cement based adhesive like Webber - I use fast set - but there are others .
Isomat is receiving good reviews.
