I had a deep-scan stud finder, and it wasn't that reliable, but I developed a technique that I had reasonable success with: do several scans at different heights and different starting points on the wall, noting where it said there was a stud. On the other hand, drywall is spongy so there's less material between the stud finder and the stud that it's supposed to be sensing. Stud finders have a hard time with lath-and-plaster because the plaster is solid and can often be 1/2" thick, then underneath the plaster you there are only small gaps between the wood lath, so you never really get the sharp change in capacitance that they look for. Another sign is the color of the dust: with drywall, it will be very white and uniform, whereas with lath-and-plaster, it's greyish and has darker flecks.Ī lot of stud finders work by detecting the change in the dielectric constant of the wall as you move horizontally across the wall. So if you have lath and plaster walls, might want to give that one a try.įrom your description of putting a screw into the walls, it certainly sounds as if you have lath-and-plaster.

Plus I'll probably wind up using it this one time and never see it again.Īny suggestions? I did try knocking on the walls and trying to hear a difference, but that wasn't really working for me.Įdit: I just wanted to let people know I used this sensor: and it seemed to work pretty well. I just don't want to go and spend the money buying if it I don't really need it. So does anyone know if there's a way I can tell if the walls are lath and plaster? Or does anyone know if this stud finder is no good? They do make a slightly more expensive model which is supposed to work better with lath and plaster walls. Plus drywall usually seems to crumble more into a fine powder and this crumbles more into sand or little pebbles.
Usually the paper coating on plaster doesn't allow it to crumble like that. I'm wondering if this is because this model is junk, or could I have lath and plaster walls? I'm pretty sure the walls are not drywall, just judging from the way they have crumbled when I tried to put a screw in them previously. Right now I think I have an idea of where two studs are but it's a very rough guess.
Occasionally it tells me there's a stud, but on subsequent passes the results are far from exact. As soon as I start sliding it, it usually just starts indicating an error. So I picked up a cheap stud sensor (Zircon E30) but I'm not having very good luck with it. It's not really meant to support any weight, just to keep it from swaying back and forth. In addition, it gives you hardware to mount the panels to the walls.

The TV itself is being mounted to some paneling which in turn is mounted to set of wooden draws.
