Wall scanners are useful tools for homeowners and professionals alike, allowing them to detect hidden objects, wires, and pipes within walls. However, if you have wallpaper covering your walls, you may wonder if a wall scanner can still effectively function. In this article, we will delve into the functionality of wall scanners and explore whether or not they can penetrate through wallpaper.
Understanding Wall Scanners
Wall scanners are handheld devices equipped with sensors that use electromagnetic fields or ultrasound technology to detect variations in the wall’s density. They work by sending out signals that bounce back when they encounter different materials behind the wall’s surface. The returned signals then provide information about the location and composition of objects hidden within the wall.
The Functionality of Wall Scanners
Traditionally, wall scanners are designed to work with bare wall surfaces. They are effective at detecting electrical wiring, stud locations, pipes, and other objects concealed within walls. However, when it comes to scanning through materials such as wallpaper, things can become more challenging.
Interaction with Wallpaper
Wallpaper, especially thicker and textured varieties, can impede a wall scanner’s ability to detect objects beneath its surface. The additional layer can absorb or scatter the signals emitted by the wall scanner, resulting in less accurate readings. Wallpaper materials contain paper, vinyl, or fabric, which can further obstruct the effectiveness of the wall scanner.
Potential Limitations
In some cases, a wall scanner might be able to penetrate through thin or non-textured wallpaper, as long as the scanner’s sensor can make contact with the wall’s surface. However, the presence of wallpaper can decrease the accuracy of the scanner’s detection capabilities. The thickness, pattern, and texture of the wallpaper can all affect the scanner’s readings, potentially leading to false positives or missed objects.
Considerations for Wallpapered Walls
If you have wallpapered walls and need to use a wall scanner, it is essential to keep a few things in mind. Firstly, consider the type of wallpaper you have. Thicker materials or those with textured patterns will likely hinder the scanner’s performance more than thin and flat wallpapers. Additionally, be aware that the likelihood of obtaining accurate readings decreases as the thickness and texture of the wallpaper increase.
Alternatives for Scanning through Wallpaper
If your walls are wallpapered and you need to scan them for hidden objects, there are alternative methods you can consider. One option is removing the wallpaper temporarily from the desired area to scan. By doing so, you will provide the wall scanner with direct access to the wall surface, improving its chances of accurate detection. However, this process may be time-consuming and could potentially damage the wallpaper.
Another alternative is to rely on alternative detection methods, such as thermal cameras or stud finders. These tools work differently from wall scanners and may provide different types of information about the objects within your walls. Thermal cameras detect temperature variations and can help locate pipes or sources of air leakage. On the other hand, stud finders locate stud positions, which can indirectly imply the location of other hidden objects.
While wall scanners are generally effective at detecting objects within walls, their performance can be influenced by the presence of wallpaper. Thicker or textured wallpapers are more likely to hinder the accuracy of a wall scanner’s readings. However, it is not impossible to scan through wallpaper, especially if it is thin or non-textured. Alternatively, you can consider removing the wallpaper or utilizing alternative detection methods to acquire the information you need about hidden objects within your walls.
