Porcelain Floor Tile Primer/Sealant over concrete

[mortarbo]

I've got good level concrete kitchen floor in this oldish house. Once scrubbed clean of grease/dirt, what Primer or Sealant do I use prior to using Mapei adhesive?. I'm using Porcelain Plank style tiles. What type of Mapei (or is there similarly alternative adhesive) that works best with primer and these tiles?
Thanks .
