Alternative Materials Replacing Lath And Plaster
Due to its potential dangers and drawbacks, lath and plaster have been largely replaced by alternative building materials. Drywall, also known as gypsum board or plasterboard, and cement board are now commonly used in modern construction due to their ease of installation, cost-effectiveness, and overall durability.
Drywall has become the standard choice for interior walls and ceilings. It consists of a layer of gypsum sandwiched between two layers of paper, providing a smooth and level surface for painting or wallpapering. On the other hand, cement board is often utilized in high-moisture areas like bathrooms and kitchens because of its resistance to water damage.
These modern materials offer improved stability, fire resistance, and ease of repair compared to lath and plaster. However, it is important to note that in certain historical or listed buildings, preserving the original lath and plaster may be necessary in order to maintain the authenticity and character of the structure.
Safety Precautions For Buildings With Lath And Plaster
To stay safe in buildings with lath and plaster, it is crucial to take certain safety precautions. Here are some key points to keep in mind:
- Regularly inspect the walls and ceilings for signs of cracking, sagging, or deterioration. This will help identify potential risks and allow for prompt action.
- Address any issues found during inspections promptly. By doing so, you can prevent further damage and ensure the safety of the occupants.
- When hanging items on lath and plaster walls, avoid placing excessive weight that could strain the already weakened structure. Heavy items like mirrors or shelves can cause the laths to break, leading to crumbling plaster or even collapse.
- It is recommended to use alternative methods, such as wall anchors or picture rail systems, to distribute the weight evenly and minimize the risk of damage.
- Extra caution should be exercised with lath and plaster ceilings. They are prone to collapse due to vibrations caused by heavy machinery, construction work, or earthquakes.
- Water damage can significantly weaken lath and plaster ceilings, making them susceptible to sagging and potentially falling. If you notice any sagging, it is advisable to have a professional address the issue promptly to avoid causing further damage or compromising the structural integrity of the building.
Remember, by following these precautions, you can ensure the safety of everyone in the building. Stay vigilant and address any potential risks proactively.
Professional Inspections And Repairs Recommended For Lath And Plaster Buildings
Given the potential hazards and risks associated with lath and plaster buildings, it is strongly recommended to seek professional inspections and repairs. Professionals who specialize in historic building restoration or lath and plaster repairs have the necessary expertise to assess the condition of the materials and identify any underlying issues.
