I live in the UK. I drilled a hole to hang a mirror and it’s slightly off, I’d like to shift it over to a new location, the new location will be half over the old hole.
So I’d like to fill the existing hole but fill it to be able to bear the weight of a heavy mirror still.
It’s plasterboard and breeze block as it’s an external facing wall.
How can I fill the hole to a strength strong enough to bear load?
