Understanding Plaster Walls
Before we dive into the methods of finding studs, it’s essential to understand the composition of a plaster wall. A plaster wall typically consists of a layer of plaster applied over a latticework of wood strips, known as laths. The laths are usually nailed to the studs, which are the vertical wooden beams that make up the frame of the house. The plaster is then applied in multiple layers, with the final layer being a smooth, finished surface.
The Importance of Finding Studs
Finding studs is crucial when working with plaster walls, as it allows you to securely attach objects such as shelves, pictures, and cabinets. Attaching objects to studs ensures that they are stable and can support the weight, preventing them from falling or becoming dislodged over time. Additionally, finding studs can help you avoid damaging the plaster or the underlying laths, which can be time-consuming and costly to repair.
Methods for Finding Studs
There are several methods for finding studs in a plaster wall, each with its own advantages and disadvantages. The most common methods include:

What are the common methods for locating studs in a plaster wall?
The most common methods for locating studs in a plaster wall include using a stud finder, knocking on the wall, and measuring from the corner of the room. A stud finder is a handheld device that uses a magnet or a sensor to detect the nails or screws that hold the plaster to the studs. Knocking on the wall can also help locate studs, as the sound will be more solid when knocking on a stud. Measuring from the corner of the room can also be effective, as studs are typically spaced 16 inches on center.
These methods can be used individually or in combination to increase accuracy. For example, using a stud finder in conjunction with measuring from the corner of the room can help confirm the location of a stud. It’s also important to note that plaster walls can be more challenging to work with than drywall, as the plaster can be thicker and more dense, making it harder to detect the studs. However, with patience and persistence, it’s possible to locate the studs and complete the task at hand, whether it’s hanging a picture, installing shelves, or making repairs.
How do I use a stud finder to locate studs in a plaster wall?
To use a stud finder to locate studs in a plaster wall, start by turning on the device and holding it flat against the wall. Slowly move the stud finder horizontally across the wall, keeping it level and steady. The device will indicate when it detects a stud, usually with a light or a beep. It’s essential to calibrate the stud finder before use, as this will ensure accurate readings. Calibration typically involves placing the device on a surface with no studs, such as a piece of plywood, and adjusting the sensitivity until the device no longer detects any studs.
Once the stud finder is calibrated, move it slowly across the wall, taking note of any indications of a stud. It’s a good idea to mark the location of the stud with a pencil, so you can easily find it again. If you’re using a magnetic stud finder, be aware that it may detect other metal objects in the wall, such as pipes or ductwork, which can give false readings. In this case, it’s best to use a capacitive stud finder, which detects the density of the material behind the plaster, rather than relying on magnetism. By using a stud finder correctly, you can quickly and accurately locate the studs in your plaster wall.
What are the advantages of using a magnetic stud finder versus a capacitive stud finder?
Magnetic stud finders are often less expensive than capacitive stud finders and can be very effective at detecting studs in walls with metal fasteners. They work by detecting the magnetic field of the nails or screws that hold the plaster to the studs. This makes them well-suited for use in walls with metal studs or where the plaster is attached with metal fasteners. However, magnetic stud finders can be prone to false readings, especially in walls with a lot of metal objects, such as pipes or ductwork.
Capacitive stud finders, on the other hand, use a sensor to detect the density of the material behind the plaster, rather than relying on magnetism. This makes them more accurate and less prone to false readings, especially in walls with a lot of metal objects. Capacitive stud finders are also better suited for use in walls with wood studs or where the plaster is attached with wood screws. While they may be more expensive than magnetic stud finders, they offer greater accuracy and reliability, making them a worthwhile investment for anyone who needs to locate studs regularly.
Can I use a drill to locate studs in a plaster wall?
Yes, you can use a drill to locate studs in a plaster wall, but it’s not the most recommended method. By drilling small pilot holes in the wall, you can feel for the stud with a wire or a small screw. If the hole hits a stud, you’ll feel resistance, and if it doesn’t, the wire or screw will slide in easily. This method can be effective, but it’s messy and can damage the plaster, especially if you’re not careful. It’s also time-consuming, as you’ll need to drill multiple holes to locate a single stud.
A better approach is to use a combination of methods, such as measuring from the corner of the room and using a stud finder, to locate the stud before drilling. This will minimize the risk of damage to the plaster and make the process faster and more efficient. If you do need to use a drill to locate a stud, make sure to use a small pilot bit and drill slowly, so you can feel for the stud without applying too much pressure. It’s also a good idea to fill the holes with spackling compound once you’ve located the stud, to repair any damage to the plaster.
How do I measure from the corner of the room to locate studs in a plaster wall?
To measure from the corner of the room to locate studs in a plaster wall, start by measuring 16 inches from the corner of the room, as this is the typical spacing for studs. Use a tape measure or a ruler to mark the location on the wall, and then use a level to ensure the mark is straight. From this point, measure 16 inches to the right or left, and mark the location again. This should indicate the location of the next stud. Continue measuring and marking the wall in 16-inch increments, until you’ve covered the entire area where you need to locate the studs.
It’s essential to note that this method assumes that the studs are spaced 16 inches on center, which is the standard spacing for most homes. However, some older homes or homes with unique construction may have different stud spacing, so it’s crucial to verify the spacing before relying on this method. Additionally, measuring from the corner of the room can be affected by any obstructions, such as door or window frames, which can make it more challenging to locate the studs. In these cases, it’s best to use a combination of methods, such as using a stud finder or knocking on the wall, to confirm the location of the studs.
What are some common challenges when locating studs in a plaster wall?
One of the most common challenges when locating studs in a plaster wall is the thickness and density of the plaster, which can make it harder to detect the studs. Plaster walls can be up to an inch thick, which can reduce the accuracy of stud finders and make it more difficult to feel for the studs. Additionally, plaster walls often have multiple layers of plaster, which can create false readings or make it harder to detect the studs. Other challenges include the presence of metal objects, such as pipes or ductwork, which can interfere with magnetic stud finders, and the risk of damaging the plaster when drilling or knocking on the wall.
To overcome these challenges, it’s essential to use a combination of methods, such as measuring from the corner of the room, using a stud finder, and knocking on the wall. It’s also crucial to be patient and take your time, as locating studs in a plaster wall can be a slow and painstaking process. If you’re not confident in your ability to locate the studs, it’s always best to consult a professional, such as a carpenter or a handyman, who has experience working with plaster walls. By being aware of the potential challenges and taking the necessary precautions, you can successfully locate the studs in your plaster wall and complete your project with confidence.
How can I confirm the location of a stud in a plaster wall once I’ve located it?
To confirm the location of a stud in a plaster wall, use a combination of methods, such as measuring from the corner of the room, using a stud finder, and knocking on the wall.
