When it comes to hanging heavy objects or installing shelves on your walls, the type of wall you have can determine the method and tools you need to use. Plaster walls are a common wall type found in older homes and buildings. Plaster is a durable and solid material, but it can pose challenges when it comes to fastening or anchoring objects to the wall. In this article, we will explore whether anchors can be used in plaster walls and what considerations you should keep in mind.
Understanding Plaster Walls
Before discussing anchors and their compatibility with plaster walls, it’s important to understand what plaster walls are and how they differ from other wall types.
Plaster walls are made by applying a mixture of wet plaster, like gypsum or lime, over a wooden or metal framework called lath. The plaster is then left to harden and forms a solid and smooth surface. These walls can provide a high-quality finish and are resistant to cracks over time.
The Challenges of Anchoring in Plaster Walls
While plaster walls are solid, they can be more delicate compared to their modern counterparts. One of the main challenges of anchoring in plaster walls is the risk of damaging the wall itself. Plaster walls can easily crack or crumble when excessive force or incorrect techniques are used.
Another challenge is finding the right spot to anchor. Unlike drywall, which has a stud every 16 to 24 inches, plaster walls have less consistent stud placement. This makes it harder to find a secure point to anchor your objects.
Choosing the Right Anchors for Plaster Walls
Despite the challenges, there are several types of anchors that can be used in plaster walls, provided they are correctly installed. Let’s take a look at some anchor options:
- Toggle Bolts: Toggle bolts are a popular choice for hanging heavy objects on plaster walls. They consist of a bolt with collapsible wings that open up behind the wall, providing added stability. When installing toggle bolts, make sure to drill a hole slightly larger than the wings to prevent cracking.
- Plastic Anchors: Plastic anchors, such as expansion anchors or screw anchors, can also be used in plaster walls. These anchors create a wider load-bearing surface behind the wall and are suitable for hanging lightweight to medium-weight objects. They are easy to install and can be found at most hardware stores.
- Winged Plastic Anchors: Winged plastic anchors are similar to plastic anchors but have wings that expand once inside the wall’s cavity. These anchors are suitable for medium-weight objects and can be installed using a drill and a screwdriver.
- Molly Bolts: Molly bolts are another option for anchoring in plaster walls. These hollow anchors have a screw and a toggle at the end. When the screw is tightened, the toggle opens up behind the wall, providing stability and load-bearing capacity. Molly bolts are suitable for medium to heavy items but require a larger hole to be drilled in the wall.
Considerations and Precautions
To ensure successful anchoring in plaster walls, there are a few considerations and precautions to keep in mind:
- Use the Right Tools: Make sure you have the right tools for the job, including a sturdy drill, appropriate drill bits, and the correct anchors.
- Locate Studs or Framework: Whenever possible, anchor your objects into studs or the wooden or metal framework behind the plaster walls. This will provide the strongest and most secure anchoring point.
- Avoid Weak Areas: Avoid anchoring near corners, windows, or areas with obvious structural weaknesses, as these areas can be more prone to cracking or damage.
- Take a Gentle Approach: When drilling into plaster walls, use low speed and gentle pressure to reduce the risk of damage. Slowly increase the pressure as you proceed.
- Test and Adjust: Before proceeding with heavy objects or shelves, test the anchor’s strength by applying gradual pressure. If it feels secure, proceed with installing your object. If it feels loose or unstable, remove the anchor and try a different method.
In Conclusion
While plaster walls can present challenges when it comes to anchoring objects, it is possible to use anchors successfully with the proper tools and techniques. Choosing the right type of anchor and adopting the correct installation method can help ensure that your objects are securely attached to your plaster walls without causing any damage. Remember to exercise caution, locate studs whenever possible, and always test the strength of your anchors before hanging heavy items.
