Introduction
Have you gotten yourself an old house, but don’t know much about plaster and lathe? Or maybe you want to work on your house that has plaster walls with a wooden lathe behind them?
What ever the case is, I’ll try to open up this topic up so you will get more knowledge about the subject. Understanding the differences between plaster and drywall, as well as the various techniques for working with these materials, can significantly enhance your home renovation experience. Knowledge of these materials can also empower homeowners to make informed decisions about repairs, renovations, and even aesthetic upgrades.
Why Plaster and Lath?
Before diving into the specifics, it’s essential to appreciate why plaster and lath were the preferred method of wall construction historically. This technique not only provided a durable and aesthetically pleasing finish but also ensured better insulation and soundproofing compared to modern drywall. The multiple layers of plaster offer a solid barrier against weather elements, contributing to the longevity of the walls. Moreover, the craftsmanship involved in plaster application can add character and uniqueness to each home.
Types of Walls in Old Houses
Naturally, plaster and lath is a quite old way to do walls. It’s a method still used today, only a wood lathe is not used sometimes as there are special boards that can be used instead. The transition from plaster to drywall illustrates a significant shift in construction practices, driven by economic considerations and advancements in technology.
There aren’t that many old drywall types, it started to become common after WWII. Its form has gone through updates with fire safety and such, but it’s pretty much the same material overall. Many homeowners today still appreciate the charm and character that plaster walls bring to a home, a stark contrast to the more sterile appearance of drywall. This appreciation often leads to a desire to restore and maintain these materials instead of replacing them entirely.
Other than that, concrete walls can be there as supporting walls and the same goes for brick walls. There are also plywood and different kinds of wooden boards that you see now and then. Each type of wall comes with its advantages and considerations, which can be crucial when planning renovations or repairs. Understanding these differences can also influence your choice of finishing materials and techniques.
If you’re interested in wooden lath and plaster removal, there is a guide on the link. There is also guide for removing plaster from brick, concrete, and drywall. These resources can provide valuable insights into the best practices for handling these materials.
Lath and Plaster Wall
When it comes to wooden lath and plaster vs drywall, the last one was originally created to offer a cheaper option for plaster walls. This led to a shift in construction methods, with many builders opting for drywall due to its ease of installation and lower initial costs. However, while drywall may be simpler to install, the aesthetic and acoustic benefits of plaster cannot be overlooked.
Plaster walls need the lath or special board behind them and there is also galvanized mesh used in modern plastering to help to fight against cracks as the wood behind lives its own life. So to cover it all and finish you need multiple layers of plaster so it will naturally cost the material and the labor. This layered approach can lead to a more resilient finish that can endure the test of time.
Now there is drywall. A board with fire-resistant attributes that can be screwed to the wall with a single man and all that needs to be done is a joint compound and some joint tape. You would place the money straight to this one for being the cheaper option. However, the trade-off is often less durability and poorer sound insulation compared to plaster walls. In fact, many homeowners find that plaster walls help maintain a comfortable acoustic environment, reducing noise transmission between rooms.
Lath and plaster repair is also something that needs some work to be done. I wouldn’t say that it’s necessarily harder than fixing holes in drywall, but it all depends on how well the wall is set in place. If there is mesh supporting it and how it all is adhering to the lath. Understanding the intricacies of these materials can save you time and money in the long run, especially if you are attempting to restore the original look of your home.
Lath and Plaster Ceiling
Ceilings are done in the same fashion as the walls. The galvanized mesh is most probably used and in older houses, it can be some sort of old chicken wire mesh. It was used a lot inside and outside, and its durability can contribute significantly to the structural integrity of the ceiling. This structural support can become crucial, especially in homes where the ceiling has experienced settling over the years.
Lath and plaster ceiling removal can be a bit more work because of that or the wire mesh can help a little. It holds the plaster together so big unexpected pieces are unlikely to fall uncontrollably. This makes the removal process a bit safer, but still requires care and proper technique. Homeowners should be aware of the potential for dust and debris during this process.
When removing lath and plaster ceiling, it’s good to make a start somewhere. Personally, I start from the middle and work my way to another edge and after that to another. I don’t have to stand under the falling plaster this way and I can use the tools and leverage to drop the old plaster and mesh down. This method minimizes the risk of injury, making for a smoother renovation process. Proper safety gear, including goggles and masks, should be worn to protect against dust and falling debris.
Lath and plaster ceiling collapse can be something that happens quite naturally. Imagine the plaster getting older and crumbling bit by bit. It doesn’t adhere so well to the lathe anymore, or it might have broken off already due to wood moving its natural life. Regular maintenance checks can help identify these issues before they escalate into more significant problems.
After some time, the mesh attachments might also be set a bit loose and suddenly, more weight is added to the points it is still attached to. At some point, it will just be too much, and it will give in. Regular inspections of your ceiling can help prevent sudden collapses, ensuring safety in your home. Keeping track of any changes in your ceiling can assist in early detection of potential hazards.
To remove it, I’d refer to removing plaster walls guide and also how to prepare the room for plaster removal. Preparation is key, as it allows you to work efficiently and safely. Ensuring the area is clear and covered can also help minimize mess and streamline the renovation process.
Lath and Plaster Exterior Wall
Now exteriors are different from indoors. The mesh can’t be installed straight to the wood as the plaster would only let moisture through, and the building systems are different. This moisture barrier is crucial for preventing damage to the underlying structure and ensuring the longevity of the exterior walls. Inadequate moisture management can lead to rot and mold, posing significant risks to the integrity of the home.
Usually, some building paper is used on top of the wood (if there is a wood wall behind) and metal lath and plaster walls are built on top of it. Metal lath or galvanized mesh serves the same purpose, to give something for the plaster to adhere to. This combination enhances the ability of the walls to resist weather-related wear and tear. Proper installation techniques are essential to ensure the longevity of these exterior walls.
Also, there is also stucco being used outdoors for rendering. There are little differences with plaster and stucco, mostly stucco being rougher and plaster being able to be used indoors and outdoors. If you’re considering using stucco, it’s important to understand how it differs from traditional plaster, including its application and maintenance requirements. The choice between stucco and plaster should be informed by the specific needs of your home, including climate and aesthetic preferences.
Lath and Plaster Asbestos
Now sometimes you hear asked is lath and plaster dangerous. The answer is, it can be, and when it comes to old buildings before the 1990s lath and plaster health risks have to be taken seriously. Understanding these risks is essential for any homeowner dealing with renovation projects in older homes. Ignoring these factors can lead to significant health hazards during renovation or demolition work.
I’ve read about asbestos in plaster, and from 1890 onward it became more common with machine technology developing. It was still used quite a lot until the mid-1980s, and today you need special equipment just to remove asbestos structures. If you suspect that your home contains asbestos, consulting with professionals is crucial for both safety and compliance with regulations. Asbestos removal is a complicated and dangerous process that should never be attempted without proper training and equipment.
So lath and plaster ceiling asbestos can be a thing as it was an effective way to make plaster more fire-resistant and better insulation. So if you have something like a room built for heating, it’s quite possible there is asbestos in the plaster. Being proactive in identifying asbestos can save homeowners from potentially hazardous situations. Regular monitoring and testing can help ensure that your home remains safe for you and your family.
It’s also good to note that it might not be the case in other rooms, so to be sure, it would be good to take a test sample and have it examined. It shouldn’t cost too much when it comes to staying healthy. Regular inspections can also help to ensure that no dangerous materials are present in your home. Keeping an open line of communication with contractors about potential asbestos should be a priority during renovation projects.
Lath and Plaster Wall Anchors
The last portion, and my favorite when it comes to plaster and drywall, is how to hang heavy things on plaster walls and other weaker building materials. I’m probably not the only one who has struggled to mount a television on a wall, especially with old plaster. The challenge often lies in finding a secure anchor point that can support the weight of the object. Getting familiar with the types of anchors available can help ensure a successful installation.
There is no working lath and plaster stud finder, at least I think so, so the next best thing would be finding the metal in the wall. The wooden lathe is attached to the studs as there is nothing else behind them. This can often lead to frustration, especially when you’re trying to achieve a precise installation. Learning about the structure of your walls can help you better plan your mounting strategy.
So to find the nails, you can use a metal finder. A wall scanner for electricity will work as well, as most often the wires to the sockets go near studs. Using the right tools can make a significant difference and simplify the process, allowing for a more seamless installation. This attention to detail can prevent mishaps that may occur during installation.
How to Hang Shelves on Plaster Walls Without Studs
So to know how to screw into lath and plaster walls would be to know how to find the wood lathe or studs. The best screws for plaster walls would be ones that go deep enough to attach to the wood behind them. It’s crucial to select the right hardware to prevent damage to the plaster and ensure that your shelves are securely fastened. The selection of appropriate anchors can also make a substantial difference in holding power.
The plastic wall plugs don’t work well if they’re attached to plaster only. The next thing to use would be lath and plaster wall anchors like molly bolts. These anchors provide a more robust solution for hanging items on plaster walls, offering greater stability and security. Understanding the different types of wall anchors available can assist you in making informed choices about your installations.
What is a molly bolt, you ask? It is a bolt designed to attach heavy objects to hollow plaster walls. It resembles the screw and wall plug, but it’s made out of metal. Understanding how these anchors work can prevent mishaps and ensure that your heavy items remain securely mounted on the wall. This can save you both time and money in the long run.
So how to use a molly bolt and how does it work? When you rotate the screw inside the metal anchor, it will cause the anchor to expand like the wall plug but also bend so that it will stick behind the plaster, anchoring into it. This unique design allows for a secure hold, making it a go-to choice for heavy installations. Knowing the correct installation technique can greatly enhance the anchor’s effectiveness.
