This video just saved my butt. Stud finder only could find one stud and ended up using a random magnet to find another and then measured the distance. Thank you for this video.
ive lived in my 100 year old apartment building for 10years and watched soooooo many videos about how to find the studs in the lath and plaster walls. ive bought literally every kind of anchor that home depot sells and the regular worker for that aisle knows me by name. haha. this is the best video i have found explaining how to find the studs in these horrible walls. THANK YOU FOR THE HELP!!!

Any advice on sourcing picture rail? I close in a week on an 1892 farmhouse. I want picture rail so we do not damage the plaster while having the flexibility to change our minds on where we hang what.
Hey V S, I look for a woodworking supply shop… or a big box store and use some molding they have that is close to the profile you want ( sometimes the desired profile can be made by combining 2 or more pieces of molding) . Lastly buy a router and a bit or 2 and create your own. Congrats on your old home! The can be a challenge. Thx for watching.
One thing I miss about the original stud finders was that they were manually calibrated with a little dial. So they didn't care about shallow scan vs deep scan. Put it on the wall, adjust the dial until the light goes out, scan around and the light comes back on wherever the wall is thicker than the setting. You can still do the same thing with most of the new ones, but, annoyingly, you have to take them apart to get to the calibration screw.
Do you have a way to tell which of your walls are plaster and which are drywall? I live in an apartment in a converted Victorian, and I know some of the walls are plaster, and others are drywall, but I don't know which are which.
Hey Meredith, Plaster is typically rougher and less smooth than drywall. Drywall comes in 4x8 or larger sheets and so the surface should be very uniformly smooth. Plaster can also display irregular hairline cracks that go in any random direction. If you take off a light switch, you might be able to see the wall make-up around the switch. Since it is’ converted ‘, it may have been completely changed to drywall. Have to be a bit of a detective… Hope that helps. Thx for watching.!
Great Video, thank you! Question - what do you use to hang heavy (25 lb) art on a plaster wall? I have 3 large pieces that I want to hang together. Ideally finding a stud - but what if one doesn’t match up? Help Please!
Hey Deborah…, Thx much! Size is a big factor - the larger - the easier it is to anchor off multiple studs. If you are talking about an old house - lath and plaster walls , then I would consider : 1) using butterfly toggles ( which open up behind the lath after being inserted into a hole, 2) mounting a thinner board across multiple studs and then using that board by anchoring the artwork into it. Could also make a larger but flat decorative structure to which artwork could be attached. 3) old houses used to have “picture rail” molding across the upper level of the room which allowed things to hang down from it. 4) look up “ French cleat “! Made of wood or modern metal designs. Hope that can spark some ideas for you. Thx for watching!
Hey Brian, The zircon L-40 ( in the video ) does sense for live wires. But even if it doesn’t detect any, I would still exercise caution when cutting into the wall. Thx for watching!
My house: west coast, 102 years old, and yes, full size, rough hewn, red wood studs. Smell like chocolate when drilled into. But here’s my question; under what circumstances might it be more efficient to gently “demo” - 7” baseboard + 2” molding on top of that to view stud positions?
@@axiomaddict not sure. I have thick lathe and plaster on most of my walls and I use a metalliscanner from Zircon. It detects nails holding lathe to the studs
@@Housebarons Oh, thank you. This is a tough problem. I have been asked to repair these walls which have decent insulation and sound resistance. People drill holes in the plaster and inject construction glue but I sometimes remove the shattered plaster, screw aluminum lathing to the wood lathing and then apply a coat of structo-lite , rough it with a sponge and then the plaster to finish. I have not mastered the perfectly flat and smooth job yet. For stud finding, I use the biggest rare earth magnets I can get ( often fails anyway ) wall tapping, drilling ( look for sawdust on the bit and resistance beyond 1 and 1/2 inches of depth), drill 3/8 hole and send a 10 awg copper ground wire, bent 90 degrees, in to feel the stud. and a camera probe made by General (larger screen than Milwaukee ) in to look at the wire situation
You can also do this..........find one stud any way you can, even drilling a 1/16th set of horizontal holes across an area where the wall sounds dense and outline the vertical stud with drill holes just in one little area. Then just measure 16" from the center of your found stud, horizontally to the left or right and you should land on another stud, and so forth across the wall. Always find the left and right margins of your stud so you know where the center is....especially if mounting heavy objects like 65" TV monitors with extension hardware that cantilevers away from the wall and swivels....you don't want 75 - 100 lbs of TV & hardware to fall on your wife's head while she's sitting there with the girls for the Saturday afternoon get together......It won't end well ..... those little drill holes are easily filled in with some 15 min. wall compound, and usual wall board finishing compound. I always put little marks where the studs are with a small marking pen, on the baseboard, that way I have a reference to where to measure from for any stud mounted stuff coming up in the future. Real lath/plaster is a pain......finding studs through drywall is childs play with a stud finder.....
Hey Nutella, To be safe you can test. But typically we worry about flooring - 9 inch tiles are often asbestos. The black flooring glue was also full of asbestos. We avoid tearing up tile. Better to cover with click lock so as not to disturb it. Do your research. Wear a rated respirator for all dusty work. Thx for watching!
My Zircon deep scan stud finder was not accurate in finding studs under plaster. I had to resort to drilling about 5 holes next to each other to find the stud. I haven't tried the magnet method yet.
Hey Joe, Check this video out. This zircon is MUCH better. Basically a strong metal detector. Easily finds the lath nails. ua-cam.com/video/ZQjDHvq79QM/v-deo.html Thx for watching!
Note that lath and plaster is tricky because it's not a constant thickness like modern plasterboard. So you'll probably need to scan the wall at multiple heights to eliminate the ghosts.
Hey Kahais, In our old house we will likely hang 1/4 inch drywall on a badly paint peeling ceiling - finding the ceiling joists would be needed for that. Hanging larger mirrors would be good to be on studs. And hanging ceiling and floor molding - all need studs to fix them tightly. Enjoy your old house - they do have an unmistakable cool vibe! Thx for watching!
@@Housebarons I recently had to hang an eighty pound TV on a wall in a part of the country known for earthquakes. The homeowner was about to hang it on the lathing. Weight high up and poorly fastened in tremor country equals fallen TV problem
I am using a stud finder as I want to mount a tv to my wall. It beeps signaling it found the edge of a stud but when I drag it along it keeps on going. Is that normal?
Hey Just…, It could mean that there is a lot of something behind the wall there. If there is just one stud, it should stop beeping after 1.5 inches or so. If there are 2 studs there, maybe beeping for 3 inches. Co up DK be multiple studs if that place in the wall is holding up a beam. Experiment with other walls. If that wall is the only one giving that signal, there must be something unusual there. Hope that helps. Thx for watching!

Hey Nicky,
Glad it worked! Thx for watching!
They're great walls, they just suck when you're trying to find the studs 😂
Just moved into a 90 yr old home. Love the home but this lath and paster is all new to me. Thx for this video got so much useful info from it.
Glad it was helpful!
Thanks for the heads up on the neodymium magnets! Just grabbed a couple and found studs behind my plaster and lathe!
Hey Pete,
Glad it worked out. Thx for watching!
This was super informative and helpful. Thanks!

Will the deep scanner identify if there’s any live wires behind the wall?

4:34 Old houses have studs and other lumber that actually are the nominal dimensions. My 123 y old house has 2x4 2x4s. They are not 1.5 by 3.5

Wow i love your comment
Do you worry about asbestos? How do you go about the job? Can you just tell or do you get a sample from every job to be safe?

Ugh. This is my problem I think. I also think there is metal in the plaster or something. The detector just beeps the whole time.
Bless you!
How far apart are the studs in this home?
Hey user…,
Generally - 16 inches. But it is 100+ years old and has been modified as well … so some surprises.
