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.
Probably the earliest flyswatters were nothing more than some sort of
striking surface attached to the end of a long stick.
