Natural slate patio - bonding agent

Hi, I'm looking for advice on laying a natural slate patio. My plan is to lay it on 50-70mm 6/1 mortar mix bed (which is on a 150mm Type 1 sub base) and wanted advice in whether I need to apply a bonding agent to the tile before laying?

hi the best way is to slurry coat the underside of the paving that's how we lay all our paving this aids in the the bond of the bed to the paving.

It would do no harm to apply I use SBR when I'm flagging plus add plasticiser to my mix a small drop is all that's needed .
