How to Mount a TV on a Lath and Plaster Wall? (Step-by-Step Guide)

You’ll be surprised to see how similar the process for mounting a TV to a lath and plaster wall is to mounting a TV onto Drywall with wooden studs. 

To easily mount a TV on a lath and plaster wall, just follow these steps: 

Step 1: Before you do any drilling or construction work, you must first decide where the TV will be mounted.

The location on your wall is crucial because you want the TV to be at a spot where it’s near a power outlet. Not only that but you also want it to be positioned in a way that allows you to comfortably watch TV as well. 

Hence, the spot on the wall you choose should have a fair amount of space in front of it where you can sit and watch TV. 

If possible, the spot you choose should also ideally be away from a window. This is important because light from the window during the daytime can cause glare on your TV screen. 

After you’ve decided on a spot for your TV, you can get started with the mounting process.

Step 2: First off, you need to identify the vertical studs in the wall as you will install the mount into these studs. 

We recommend that you install the TV mount into a minimum of two studs. If possible, three studs are even better. 

Use your stud finder to find the locations of the vertical studs in the wall. Your stud finder will flash or beep to indicate the location when it runs over a stud. 

Mark the locations of the studs in the wall using a pencil or a marker. 

Step 3: Hold the TV mount up to the wall so that its screw holes align with the locations of the studs you found in step 2. 

Mark the locations of the screw holes with a pencil or a marker. 

Step 4: Use your high-impact drill to drill holes into the locations you marked in step 3. 

It’s important that you be gentle at this stage. Gently pull the trigger and slowly push the drill in as it starts to penetrate the wall. 

You want the holes to be slightly smaller than the plaster anchors you are using. 

Step 5: Insert the plaster anchors into the holes you drilled in step 4. 

Use your drill to secure them into the wall. Be careful not to overdo it as that can damage the wall and make the hole much bigger than is necessary. This would make the hole unusable.

Step 6: Use your screwdriver to remove the screws from the plaster anchors. 

Step 7: Hold up the TV mount so that its screw holes align with the plaster anchors on the wall. 

Next, insert the screws you removed in step 6 back into the plaster anchors with the mount. Rotate the screws as much as you can by hand and then use a screwdriver to finish the job.

Step 8: Attach the mounting bracket to the back of your TV. 

You can easily do this by laying your TV flat on a soft surface so that its back is facing towards you. Make sure to use an extremely soft, flat surface because you don’t want the screen to get scratched. 

Insert the assorted screws you got with the wall mount and tighten them with a screwdriver to firmly attach the mounting bracket to the back of your TV. 

Step 9: Lift the TV up and slide the mounting bracket into the wall mount you attached to the wall in step 7. 

You will need to raise the TV higher than the wall mount and slowly lower it until the mounting bracket locks in place with the wall mount. 

Depending on the manufacturer and model, you may hear a loud click or some similar sound that indicates that the mounting bracket has been secured to the wall mount. 

Step 10: That’s pretty much it. All that’s left to do is test the stability of the wall mount. 

Hold your TV gently and try to push it from side to side. If it wobbles a little too much, then that means a screw or multiple screws are loose. 

In this case, you’ll need to identify which screws have not been properly tightened and tighten them again. 

Keep repeating this process until the TV does not budge and is firmly attached. 

You should contact a professional if the TV is not firmly attached.
