i need to maintain a clean and porous surface on my basement floor in
order to apply a waterproofing product. unfortunately half of it was
covered with those cheap linoleum squares and the adhesive that remains
is a thin layer of super stiff puddy. i spent a whole day doing about
80 sq/ft. hitting it with an angle grinder. first with a steel brush
attachment to remove the bulk, then with a cement attachment to remove
the residual. the tricky part is i needed to remove the right amount of
cement as i take off the adhesive. otherwise the grinder gets gummed
up and just spreads the adhesive around. very tedious.

i feel like i need to stick with a mechanical method as the concrete is
supposed to have an open and clean surface for application. i don't
want to risk using some degumming agent or lacquer thinner.

any ideas? i'm thinking i'd have to rent some pro-ish floor refinishing
gear. i'm in san francisco so maybe that wouldn't be too hard.

much thanks

Acid might work if you have a way of rinsing it off.
