Porcelain Wall Tiles -What adhesive

[Cristop]

I am tiling a shower tray and bathroom . The tiles that are selected are a porcelain tile. Areas to be tiled are an existing concrete block wall and an area I have relined with the waterproofed plaster board recommended for shower areas. What tile adhesive should I use since I am concerned with adherence utilising porcelain tiles , the possibility of non absorbtion surfaces etc.
What is the best way to drill a porcelain tile - I have tried a sample and seem to have little effect except if I use a hammer action. Drill wear is also an issue . Cutting via a diamond wheel is ok.

Hi and welcome to the forum. Have you tried the search facility - all these questions have been well covered.

I guess the drilling as been well covered but as far as the adhesive goes it gets more non cohesive !
Yes it seems to be a mixed pack rather than a ready mix preperation but I am still somewhat confused especially when dealing with various surfaces - some permeable and some I presume non permeable. What is the best mix pack to select?

You've lost me - but I'll play ball anyway.... if you're using tiles 30 x 30cm and under, use Bal White Star or Bal Blue Star (these are pre-mixed adhesives). If using larger tiles, use a powdered adhesive suitable for porcelain tiles - any brand will do (apart from unibond - but that's just a personal preference).
