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.

Yes! Sort of. Most magnet type stud finders don’t work effectively since they are dependent on locating the fasteners (screws) used to secure the drywall and they can be very difficult to locate.
How do you mount a TV on a plaster wall?
Most mounts consist of two pieces. The first piece of the mount will attach to your wall. Use a drill and the provided hardware to mount it directly into the stud so that the plaster is not damaged. Attach the second piece of the bracket to your TV.

What is behind plaster walls?
Lath and plaster If your home was built before 1950, you most likely have traditional lath-and-plaster walls. Wooden lath strips are nailed across the framing and then plaster is applied to them. The plaster that oozes between the lath strips is called the key, which locks the plaster and lath strips together.
Are there studs in lath and plaster walls?
Prior to the 1950s, most walls were built using a combination of vertical studs, horizontal wooden beams called laths and plaster seams. 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.
How can you tell where a stud is in the wall?
A good starting place is 16 inches from a corner. For better precision, use a tape measure and mark 12 inches, 16 inches, and 24 inches from the corner. Tap the wall at each distance. You’ll hear a solid sound when you tap the part of the wall that is supported by a stud.
How do you find a stud without a finder?
If you don’t find signs of a stud 16 inches from the first one, measure 24 inches from the first stud and look again there. Drive a small nail into the wall where you believe you have found a stud. If the nail doesn’t hit wood under the plaster or drywall, pull it out and insert a wire hanger into the hole.
