Thanks for the reply [b]darren[/b]. I received the same advice a few days ago after phoning up the chappie at the tile shop where I bought my adhesive. So, I bought a 10mm round-notch trowel and have been practicing my technique on small shelf areas before I tackle the large wall.

Since I bought Ardex X 7 G Plus (polymer-modified cement-based) adhesive, I thought it was best to stay with the one manufaturer and went for Ardex P51 primer instead of the BAL alternative. It is designed for the same purpose.

I must say: I'm quite surprised that materials technology is so advanced and ultra specific. Once you make the fateful decision to try and use the most suitable materials for the job, rather than the cheapest or the easiest to obtain/apply, specification becomes the lion's share of renovation!
