Wondering how extremely careful one needs to be with the black old glue in our late '50s apartment.
(Negative asbestos test)
I've removed the carpet and we've hand-scraped down to the concrete. The concrete is clean in some places and black in others. The glue has been brittle in some places and more sticky in others.
So now there's mostly just a film left that can't be scraped off without going down into the concrete.
For those of you who know about these things, is this sufficient or should we work more on removing the film?
Is there a primer or something similar that can be applied to this so that it blocks/helps the adhesive to stick and possibly not react with the black?
In another room, the concrete is a bit more black-spotted than here.
Thanks for the tips

Try to maybe rent a concrete grinder and remove everything, then prime properly and on tiles, and it will probably be good.
