Only if it needs diluting

Some primers must be diluted first.
Others require a build up of different strengths.
Some primers will readily sit on top like a skin if not applied correctly.

This was just straight from the tub

primed the tiles for some self leveler on top because some needed leveling because of low spots. Tiles can go onto tiles if primed

Used what tile store recommended. If its glazed as you say, should i take it all off and redo with different primer.

Actually, reading the info it sounds like it should be suitable.
I've never used it though.

The best I’ve used for this type of application is called Super Grund from Isomat.
It’s a resin based grit primer.
It’s like painting on neat sandpaper.
