You’ll need to scabble the floor for a key or sand it clean, vacuum, grit prime and leveller. Phone your intended adhesive manufacturers tech help line, some of them vary in what they’ll advise their products can do.

Rather than scrabbling it might be possible to use two coats of epoxy primer with sand scatter into the second coat to give you the rough texture to key to.
