Luxury vinyl tiles on old well bedded and flat adhesive?.

Hi, as the listing says I am about to lay 25m2 of Polyflor vinyl tiles(it’s the same as Karndean). The previous covering was carpet under which there were those very old almost plastic 300 x 300 tiles. They have come up very easily and have left a very thin perfectly smooth black coating on the concrete floor.
Question is, am I ok to lay straight on top or do I need to prime and apply a levelling latex.

I keep getting different recommendations but someone may have experienced this issue.

cheers

In some construction that thin black smooth coating was the DPM ?

How old is the property?

There is a possibility of the old tiles containing Asbestos? did you get them tested?

Google "Thermo-Plastic floor tiles"

The property is a 30 year old semi with full dpm protection.
The tiles that we lifted were commonly called ‘Marley vinyls’ they are not the very old stuff from the 40’s so asbestos is not an issue.
I’m thinking something like Ball Stopgap 1200 might do the trick.
