How to Find Studs in Plaster Walls
To find studs in plaster walls when standard stud finders don’t work, one alternative method is to use a strong magnet along with dental floss or string.
By dangling the magnet against the wall and slowly moving it horizontally, the magnet will stick to the wall directly above a stud location, indicating the presence of a stud.
This technique works because the wood lath in the wall is nailed to the studs and attracts the magnet.
It is important to use a strong magnet for this method to be effective.
Additionally, adjusting the magnet vertically may help locate hidden nails in spaces between laths.
Alternatively, a powerful magnet like StudPop can be used, which pops into place when a stud fastener is detected.

Did You Know?
1. The term “stud” originally referred to sturdy pillars or supports in old English architecture, which eventually influenced its use to describe the underlying wooden framework of walls.
2. Without a stud finder, one can still find studs in plaster walls by tapping on the wall surface: a hollow sound indicates the area between two studs, while a solid sound indicates a stud.
3. In some older homes, horsehair was mixed with plaster to create a stronger wall surface. Consequently, finding studs in these walls may be more challenging due to the added density.
4. X-ray machines were used in the mid-20th century to locate studs in walls during home renovations. However, due to concerns about radiation exposure, this method quickly fell out of favor.
5. In addition to using a stud finder or tapping method, stud locations can sometimes be identified by observing patterns on the wall, such as visible nails or screws that secure the plaster to the studs.
Using A Strong Magnet With Dental Floss To Locate Studs
Plaster walls can pose a challenge when it comes to finding studs, especially when standard stud finders fail to deliver accurate results. However, there are alternative methods that can be used to reliably locate studs in plaster walls.
One such method is using a strong magnet in combination with dental floss or string.
To begin, you will need a strong magnet, such as a rare-earth magnet, and a length of dental floss or string. Tie one end of the floss or string securely to the magnet and hold the other end in your hand.
Stand directly in front of the wall you wish to locate the studs in.
Dangling The Magnet And Moving It Horizontally
To locate studs using this method, you will need to dangle the magnet against the wall and slowly move it horizontally. Start from the top of the wall and move the magnet in a straight line horizontally while maintaining a steady pace. It is crucial to be patient and move the magnet at a consistent speed to ensure accurate readings.
As you move the magnet along the wall, pay close attention to any changes in resistance or pull. If the magnet suddenly sticks or attracts more strongly to the wall while moving horizontally, it is likely that you have located a stud behind the plaster. This method works because the wood lath in the wall is nailed to the studs and attracts the magnet.
- Dangle the magnet against the wall
- Move it horizontally in a straight line
- Maintain a steady pace
- Pay attention to changes in resistance or pull
“If the magnet suddenly sticks or attracts more strongly to the wall while moving horizontally, it is likely that you have located a stud behind the plaster.”
Magnet Sticking To Wall Indicates Stud Location
The key indicator that you have found a stud using the magnet and dental floss method is when the magnet sticks to the wall directly above a particular location. When this happens, you can be confident that there is a stud behind the plaster at that spot.
Keep in mind that the magnet may not stick to every part of the wall, so it is crucial to mark the location where the magnet does stick. This will help you accurately determine the position of the studs when it comes time to hang heavy objects or install shelves on the wall.
- Make sure the magnet sticks directly above the location
- Mark the spots where the magnet sticks for accurate stud placement
- Helpful when hanging heavy objects or installing shelves on the wall
“The magnet and dental floss method is a reliable way to find studs behind the plaster. Remember to mark the spots where the magnet sticks to ensure accurate stud placement.”
Wood Lath Nailed To Studs Attracts Magnet
The magnet sticks to the wall in certain spots due to the presence of wood lath and the attachment of the lath to the underlying studs. Wood lath is a series of narrow, thin strips of wood that are placed horizontally across the studs and serve as a base for the plaster. These strips are typically fastened to the studs with nails.
When using a strong magnet, it is attracted to the nails that secure the wood lath to the studs, causing the magnet to stick to the wall at those precise locations. By identifying these areas, you can confidently know where the studs are located behind the plaster.
Importance Of A Strong Magnet For Effective Results
To ensure accurate and reliable results when locating studs in plaster walls, it is essential to use a strong magnet. Weak magnets are less likely to generate sufficient attraction to the nails in the wood lath, making it difficult to discern the stud locations accurately.
Investing in a rare-earth magnet or a specifically designed stud-finding magnet, such as StudPop, can greatly enhance the effectiveness of this method. StudPop is a powerful magnet that pops into place when it detects a stud fastener. Its strong pull ensures that you will have precise stud locations every time.
Adjusting Magnet Vertically To Find Hidden Nails
In some cases, the nails securing the wood lath to the studs may be positioned in the spaces between the lath strips, making it more challenging to locate them horizontally. In such situations, you can try adjusting the magnet vertically to find hidden nails.
By slowly moving the magnet up and down the wall while maintaining contact with the surface, you may detect slight variations in resistance or pull. These variations indicate the presence of hidden nails and, therefore, the position of the studs. Be patient and thorough in your search, adjusting the magnet vertically as needed to find all possible stud locations.
Locating studs in plaster walls can be accomplished even when standard stud finders fail. Utilizing a strong magnet with dental floss or string provides a reliable alternative method. By dangling the magnet against the wall and slowly moving it horizontally, you can identify stud locations based on the magnet sticking to the wall. The wood lath in the wall, attached to the studs, attracts the magnet, enabling you to locate studs accurately. It is important to use a strong magnet for effective results, and adjusting the magnet vertically can help find hidden nails in between the lath strips.

By running the stud finder along the wall, the magnets will attract to the metal in the studs, indicating their presence. This method provides a more precise and accurate result in identifying the location of studs.
Another approach is using a stud sensor. These electronic devices are designed to detect changes in the density of the wall. By placing the sensor against the wall and moving it horizontally, it can detect the denser areas indicating the presence of a stud. With the help of a stud sensor, you can quickly identify the exact location of studs in the wall, making it easier to securely hang objects or perform any modifications.
Are studs always vertical?
While studs are typically vertical, they are not always so. In certain construction techniques, such as when building a curved wall or an angled partition, studs may be oriented horizontally or at an angle to accommodate the desired design. The key is to ensure structural integrity and stability while achieving the desired aesthetic or functional outcome. Additionally, studs can also be placed diagonally in specific situations where added strength or support is required, demonstrating the versatility and adaptability of wall framing techniques.
1. Can electronic stud finders be used to locate studs in plaster walls, or are there alternative methods that work better for this type of wall?
Yes, electronic stud finders can be used to locate studs in plaster walls. These tools typically work by using sensors to detect changes in density behind the wall, which can indicate the presence of a stud. However, due to the varying composition and thickness of plaster walls, electronic stud finders may not always provide accurate or consistent results. In such cases, alternative methods such as tapping the wall to listen for a solid sound or using a strong magnet to find nails or screws beneath the plaster can be more reliable for locating studs.
