Finding Nails and Studs in Lathe and Plaster Walls

When working with lathe and plaster walls, it can be challenging to find the nails or studs that hold the plaster in place. This is because the plaster can mask the presence of these fasteners, making it difficult for a stud finder to detect them accurately. However, there are several methods you can use to locate the nails and studs in lathe and plaster walls.

One way to find the studs is to knock on the wall until it doesn't sound hollow. This method involves gently tapping your knuckles against the wall to locate the studs. When you hit a stud, the sound will be more solid than when you're hitting the empty space between the studs. However, this method may not always work, as some lathe and plaster walls can have horizontal or diagonal bracing that can make it difficult to detect the studs.

Another way to find the studs is to use a magnet. Small magnetic stud finders with pivoting magnets can dip when they're over a nail, indicating the location of the stud. You can also hang a small magnet from a string and move it slowly along the wall until it's attracted to a stud. Zircon is a good brand to consider for this type of tool.

If you're unable to find the studs using these methods, you may need to use a detector that has a metal mode or one that's designed specifically to detect nails. These detectors can help you locate the studs by detecting the presence of metal.

When it comes to hanging items on plaster walls, it's essential to check the weight rating of the command strips you're using to ensure they're strong enough to hold the item securely. You should also be aware that there may be horizontal or diagonal bracing in the wall that can affect the stability of your hang.

In some cases, it may be possible to search for the nails that attach the wood lath to the studs using a detector with a metal mode or one specifically designed for this purpose. However, if you're working with metal lath, you may need to use trial and error or moly bolts to secure the item.

In summary, finding nails and studs in lathe and plaster walls can be challenging, but there are several methods you can use to locate them accurately. By using a combination of these methods and taking the necessary precautions when hanging items, you can ensure that your project is successful.
