Do stud finders work on lath and plaster walls?

Because standard stud finders detect a change in density inside the wall, they don’t work on lath and plaster — the density inside these walls is not constant enough. If you have just moved into an older home and your stud finder isn’t doing its job, invest in a metal scanner instead.

To function properly, the wall surface must have a consistent density level, and be less dense than the wood stud. Stud finders, however, will not always return accurate results with lath and plaster walls because of the very inconsistent method by which they are constructed.

How can you tell where a stud is in the wall?

How do you find a stud without a finder?

If the nail doesn’t hit wood under the plaster or drywall, pull it out and insert a wire hanger into the hole.
