Hi,

A friend has taken on a small warehouse unit and the floor looks like
concrete painted over. The previous occupiers have part carpeted it
and fixed this, and a metal strip, down with adhesive.

Any ideas what could be used to clean the floor of the adhesive if the
carpet is removed? He wants more of the floor bare. Looking at
taking up around 11ft x 8ft.

One of these & plenty of elbow grease

Might need some kind of solvent depending on the type of glue, try white
spirit of meths to start with.

If they've used contact adhesive then it may benefit from being charred
with a blowlamp before scraping it off but repainting may be necessary.
