Mounting a TV to a Lath and Plaster Wall: A Step-by-Step Guide

When it comes to mounting a TV to a lath and plaster wall, it's essential to do it correctly to avoid damaging the wall or compromising its structural integrity. In this article, we'll provide you with a step-by-step guide on how to mount your TV safely and securely to a lath and plaster wall.

Understanding Lath and Plaster Walls

Lath and plaster walls are made of horizontal strips of wood called laths that are covered in a layer of plaster. These types of walls are common in older buildings, particularly those built in the mid-20th century. Unlike modern drywall construction, lath and plaster walls can be more challenging to work with when it comes to mounting heavy objects like TVs.

Choosing the Right Mounting Method

When mounting a TV to a lath and plaster wall, you have several options to choose from. One popular method is to use toggle bolts that go through the plaster and into the laths behind. This method is effective but requires careful placement to avoid cracking the plaster.

Another option is to use EMT (electrical metallic tubing) or other tubing to reinforce the wall before installing the TV mount. This method provides added stability and helps prevent damage to the wall.

Using Toggles with Wide Wings

For maximum stability, consider using toggles with wide wings that can grip the laths behind the plaster. These types of toggles are designed specifically for mounting heavy objects on lath and plaster walls and provide a secure hold without damaging the surrounding area.

Mounting the TV Board

To ensure a secure mount, attach the TV board to the wall using bolts or screws that go through the board and into the laths behind. Make sure to use big fender washers under the head and nut to prevent damage to the plaster when tightening the nuts.

Pumping Insulation Foam for Added Stability

If you're concerned about the stability of your lath and plaster wall, consider pumping expanding urethane foam insulation into the cavity to make it more rigid. This method can help provide added support for the TV mount and prevent damage to the surrounding area.

Mounting a TV to a lath and plaster wall requires careful planning and execution to avoid damaging the wall or compromising its structural integrity. By following these steps, you can ensure a secure and safe installation that will last for years to come. Whether you choose to use toggle bolts, EMT tubing, or toggles with wide wings, remember to always prioritize stability and security when mounting your TV to a lath and plaster wall.
