How to Find Studs Behind Lath and Plaster
Finding studs behind lath and plaster is a common challenge for DIY enthusiasts and professional renovators alike. Whether you’re hanging heavy artwork, installing shelves, or just curious about the structure of your walls, knowing where the studs are can make all the difference. Here’s a step-by-step guide on how to find studs behind lath and plaster efficiently and safely.
1. Use a Stud Finder
The most straightforward method to find studs is by using a stud finder. These devices are designed to detect the presence of wood studs behind walls. Simply move the stud finder across the surface of the wall, and it will indicate when it has found a stud. Modern stud finders are highly sensitive and can detect studs even when they are covered with lath and plaster.
2. Look for Visible Signs
Before using a stud finder, take a moment to visually inspect the wall. You might notice gaps between the lath, which can indicate the presence of studs. Also, walls with windows, doors, or switches typically have studs around these areas to support the structure.
3. Tap the Wall
Another method is to tap the wall gently with your knuckles. Wood studs typically sound solid and dense, while hollow areas sound more like an empty space. However, this method can be less reliable and may require some practice to master.
4. Use a Magnet
A small, strong magnet can also help you locate studs. Move the magnet along the wall, and it will stick to the wood studs. This method is particularly useful if you have a small magnet that won’t be damaged by the wall surface.
5. Measure from the Floor or Ceiling
If you have access to the attic or basement, you can measure the distance from the ceiling or floor to the center of the stud. Studs are typically 16 inches apart on center, but this can vary depending on the construction. Use a tape measure to find the center of the stud and then mark the wall accordingly.
6. Be Prepared for Variations
Keep in mind that the distance between studs can vary, especially in older homes. Some homes may have 12-inch or 24-inch stud spacing, so don’t be surprised if your measurements don’t match the standard 16-inch spacing.
7. Safety First
When working with lath and plaster, always wear protective gear such as gloves, safety glasses, and a dust mask. Lath and plaster can be dangerous to work with, as it can easily fall and cause injury.
Conclusion
Finding studs behind lath and plaster may seem daunting, but with the right tools and techniques, it’s a manageable task. Whether you’re using a stud finder, tapping the wall, or measuring from the floor or ceiling, knowing where the studs are can help you hang heavy items securely and make your home improvements more effective. Always prioritize safety and take your time to ensure accurate results.
