I want to hang a heavy piece of art (~8 lbs) over the bed, so I want to make sure that it is very securely attached. I was going to use a toggle bolt, but after drilling the hole in the wall, it seems to be about an inch of plaster attached directly to the brick of the building.
I read that there is something called a sleeve anchor for brick, but after watching a few videos, I'm not sure if the anchor would hold if it is not flush against the brick, due to the layer of plaster.
Does the entire sleeve anchor need to be in the brick, or could it be half in brick and half in plaster?
The building is a medium sized apartment building, around 100 years old in a major city in the USA.
