You would be best contacting the adhesive company and asking them. They will have an preferred method

generally on the adhesive instatlation instrustions on the tub or bag it will state which type of primer should be used just the same as most building materials

Features
• C2 high bond strength, exceeds 1.7MPa • S1 high deformation, exceeds 2.5mm • E extended open time • T non-slump
• Exceeds the requirements of AS4992 • Instant grip and non-slip/slump • Cures on absorbent and non-absorbent surfaces • Flexible
Performance Data
Exceeds the performance requirements of AS4992
Tensile Adhesion Strength
1.7 MPa (28 days)
Coverage (approximate) 6mm notch trowel 10m2/20kg
10mm notch trowel 7m2/20kg
Specification
The ceramic tile adhesive will be a white polymer modified cement based with non-slip/ slump and non-shrink properties and have a minimum tensile adhesion strength of 1.7 MPa such as Drymastic manufactured by Construction Chemicals and shall be applied strictly in accordance with the manufacturers instruction.
Surface Preparation
The surface to be tiled must be firm and clean, free from dust, waxes, paint and other contaminants. Steel floated concrete floors must be mechanically roughened, washed thoroughly and allowed to dry prior to tiling.
