In answer to your question, I would have to ask what color was the adhesive on the floor?
Black! not good. yellow, clear, or white, so, so, .
If the adhesive that that was used was black, it will come up with a floor scrapper, but you need to be able to know if it is of the asbestos content.
(old cut-back adhesive).
Water based adhesive is more friendly and will be a big B to scrap. Most or all of the majority of the trowel notch adhesive marks have to be removed or will crop up in the final product finish.
If that adhesive can not be peeled off, I would recommend skim coating the whole floor with a product like ARDEX. Very good product for skim coating a floor to make ready for floor tile.
This ARDEX feather finish is designed for this type of application and is great to work with.
Hope this helps.
