A metal sensor or dedicated metal scan mode helps you pinpoint tiny nails and tacks that fasten all pieces of wood lath to studs.

Do stud finders work on lath and plaster walls?
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. First, wood laths, narrow strips of wood, are nailed horizontally across vertical wall studs. Two wet coats of plaster are applied to the laths.
How do you hang things on lath and plaster walls?
Plastic wall anchors don’t work with lath and plaster walls. Instead, use plaster anchors made of metal like a molly bolt or a toggle bolt. Be sure to use one that’s long enough to get behind the plaster and lath. When drilling into plaster, you’ll need to use a masonry bit.
How do I find ceiling joists under lath and plaster?

Can you mount a TV on lath and plaster?
You most certainly can mount this on lath and plaster walls. The key is finding the studs – and honestly finding the center of the studs. The mount itself is really heavy, and then you’re putting a heavy television on the end of a long lever. Just make sure you’re anchoring that truly in studs and not just the lath.
Can you drill into lath and plaster?
Hanging items on plaster almost always involves drilling a hole first, since nails may not penetrate the thick surface and they tend to leave cracks if they do make it through the plaster. Drilling a hole in plaster safely prevents cracking around the hole area while minimizing the amount of plaster dust kicked up.
How much weight can a screw hold in plaster?
Both plaster and drywall can hold roughly the same amount of weight. A screw driven into a stud in both plaster and drywall can hold 80–100 pounds (36–45 kilos). Anchored screws or other fasteners set into the wall where there is no stud can hold up to 20 pounds (9 kilos).
How much weight can a molly bolt hold?

Do plaster walls have studs?
It’s pretty simple to find a stud in common drywall. Plaster can be too thick or dense to find a stud with common stud finders, which is probably why you’re finding that these don’t work. And if the lath is a metal wire type, instead of older wood lath, a stud finder will produce false readings.
Can you screw into plaster?
Screws are your ultimate option for hanging things on plaster walls without picture rail. For lighter items, screwing into the plaster with a 1 1/4” drywall screw can get the job done. For heavy items, you can opt screws with masonry anchors.
Can you use a stud finder to find ceiling joists?
Using a stud finder is the easiest way to find your ceiling joist because there is no guesswork. Purchase a high-quality stud finder. If it doesn’t light up every 16 or 24-inches, then the ceiling joists probably run in the other direction, so try it again in that direction.
Can I use my phone as a stud finder?

Can drywall anchors be used in plaster?
Drywall anchors can be used on plaster walls the same way they’d be used on drywall. However, in many cases, they’re not necessary, because it’s easier to get a screw into the lath.
