My home dates to the 1890s. It has clearly been through many renovations over the years before I owned it. The walls in my living room have defied all stud finders: normal ones find nothing, magnetic finders read the whole wall as a stud. Tonight I found this when removing a vent cover.
It looks like the wall is plaster over metal mesh. Can anyone give me any idea of when this construction was used? Is there anything special I need to know about? I'm just looking for information.
