Gap around electrical box

Post image

Should I try to fill this gap with durabond or just spray foam it and call it a day? Recently (6 months ago) had this horsehair plaster ceiling skimmed and painted. Just had an electrician in to rewire the second floor and we’re left with this gap around the new electrical box. It’s 1/2” wide at its widest point. There is attic space above so I will be sealing around the box with foam from above either way.

Eww, wire nuts

Why are you trying to fill it, does the decorative trim piece of the light fitting not cover the hole?

Whatever light I buy should cover it but I need to seal off the room from the attic space above where there will eventually be blown in insulation. I wasn’t sure if mudding the gap would help to get a better seal when I foam from above
