One of the examples is StudBuddy Plus magnetic stud finder. Some stud finders that will do the work: Strong Magnetic Stud Finders: Some are Franklin Sensors ProSensor Professional Stud Finder, StudPoP “Grip” Magnetic Stud Finder, Zircon Handheld Electronic Metal Detector, and so on. Hence, special stud finders are used in this case. Therefore, the above-mentioned characteristics make the work of a standard stud detector hard and non-accurate. Additionally, the texture of the wall is uneven and rough due to the components used in it.īesides, the reason plaster walls are desired in some of the houses instead of drywalls is the roughness of their texture. Lath and plaster walls make very thick walls together (almost 1-inches thick), thicker than drywall.ĭrywalls are mostly ½ inch thick, making lath and plaster walls thicker than drywall. Yes, a special or strong stud finder is needed to detect or find the studs behind lath and plaster walls. Do you need a special stud finder for plaster and lath walls? The dielectric readings given by an electric finder aren’t accurate due to the unevenness of the plaster wall. While the magnet in a magnetic detector isn’t always strong enough to detect metal through the wall because plaster walls are thicker than drywalls. This uneven, or rough texture is what makes it desirable and gives an aesthetic theme to homes that represent an old or ancient theme. It’s thicker–almost 7/8 inches without the lath and if lath is added, the wall becomes 1-inch thick, which is thicker than most drywall, more fire-resistant than drywall, and not to mention more uneven. Characteristics of a Plaster Wall:Ī plaster wall is usually composed of lime, gypsum, or cement with sand and water. Moreover, this is more reliable since studs might not always be metallic and finding out the presence of those frames with the help of density readings seem safer and accurate. These stud finders use the dielectric reading of a wall and let the user know the presence of a stud once there’s a change in the dielectric readings. Working procedure of an electric stud finder: The detector beeps when they find any metal since metals have electric properties, and ultimately magnetic ones. The detector looks for materials that conduct electricity and show magnetic properties and discards any material that’s an insulator since they show little to no magnetic properties. These devices detect the screws and nails driven in a stud, and in some cases, the studs–if they’re made of metals. They fail because: Working procedure of a magnetic stud detector: The hand-held magnetic stud detectors and electric stud finders, mainly fall into the category of standard stud detectors.
