Hanging Kitchen Cabinets On Lath And Plaster Walls

Lath and plaster walls, a common construction method in older homes, present unique challenges when installing kitchen cabinets. The traditional plaster surface can be brittle and prone to cracking, while the underlying lath structure might not provide the necessary support for heavy cabinets. However, with the right approach, hanging kitchen cabinets on lath and plaster walls is achievable, ensuring a secure and long-lasting installation.

Assessing the Wall Condition

Before embarking on the installation process, a thorough assessment of the wall is crucial. Carefully inspect the plaster surface for any signs of cracks, loose plaster, or areas where the lath is exposed. If cracks are present, they need to be repaired with patching compound. Loose plaster should be removed and the underlying lath reinforced. Furthermore, check the lath for sound integrity and ensure it is securely attached to the wall studs. Weak or compromised lath should be reinforced or replaced entirely.

Choosing the Right Hardware

Selecting the appropriate hardware plays a vital role in ensuring secure cabinet installation. Traditional drywall screws might not offer sufficient holding power in lath and plaster. Instead, opt for heavy-duty screws specifically designed for masonry. These screws, often referred to as concrete or masonry screws, have a specialized tip that drills into the plaster and lath, providing a strong anchor. Additionally, consider using toggle bolts, which expand behind the wall, providing a secure hold in hollow areas where the lath may not be directly attached to a stud.

Installation Techniques

When hanging cabinets on lath and plaster walls, it is essential to take extra precautions to avoid damage.

Pilot Holes: Before driving screws into the plaster, drill pilot holes slightly smaller than the screw diameter. This step helps to prevent cracking of the plaster by reducing the force required to drive the screws.
Locate Studs: While lath and plaster walls may not provide consistent structural support, locating studs is still crucial. Use a stud finder to identify studs and install screws directly into them whenever possible. This ensures optimal weight distribution and stability.
Reinforce Weak Spots: If the lath structure appears weak or the plaster is particularly brittle, consider reinforcing the attachment points. This can be done by installing a small piece of plywood or a metal plate behind the cabinet mounting points.

Hanging kitchen cabinets on lath and plaster walls requires careful planning and execution. By thoroughly assessing the wall condition, choosing the right hardware, and following proper installation techniques, homeowners can ensure a secure and long-lasting installation. Remember, patience and a methodical approach are key to achieving a successful outcome. If you're unsure about any aspect of the process, consulting a professional contractor is always the safest option.
