How to fill holes in the wall or remove old electrical installation.

[laserorm]

Hello,

I'm renovating the basement. I've sanded off all the paint from the walls and will soon be plastering them.
There are a couple of old unused electrical installations embedded in the walls that I need to handle somehow. Either I fill them with something, in which case what? Husfix?
They are entirely metal, so not much adheres to them.

Alternatively, I could try to remove the installations before filling with something suitable. Does anyone know the easiest way to remove them? They are very firmly attached, so I assume they have protruding parts that were cast into the concrete.

Thanks!

Pull out the nails and then pry out the box. If there are no nails, start prying a bit. It doesn’t have protruding parts. It usually works with pliers and maybe a screwdriver to pry and get some grip. It's only held in the conduit which seems to come from below here, but that joint is just pressed and releases easily.

Used the multitool and made small cuts in the box, then it was easy to pry it out with a screwdriver.
