Tools Required to Mount a TV

You need to make sure you have the following items before you attach your TV mount to the wall.

1. TV Mount

Mostly the new TVs come with a TV mounting kit. Wall mounts are custom made for a particular size and weight.

If you have to buy the mount individually, ensure it is compatible with your TV model. You shouldn’t be surprised if your 50-inch TV falls into a 32-inch mount.

2. Stud Finder

A stud locater is a device that helps to find screws behind walls. There are two types currently available: magnetic and electric stud finders.

3. Plaster Wall Anchor

Sometimes there are no studs behind the walls. In such a scenario, finding the ideal location to hang your TV becomes challenging.

This is when plaster anchors and fastening screws come in handy!

You should use Anchors that are mainly developed for plaster walls. Generally, the anchor should be strong enough to support at least 150 pounds.

4. Drill Equipment

 A drilling machine is required to create round holes and drive screws into the wooden studs.

Drill bits will also be required for this task. But, make sure the pieces are about 1/8 inch smaller in diameter than the anchor you’re using to hang the TV.

5. Bolts


The majority of TV mounting panels come with bolts to secure them to the wall. The bolt tights the mounting panel and strengthens the entire structure. M8 bolts are often the best choice for this job.

6. Screwdriver


A screwdriver is a handy device with a slotted head that is used to turn the fasteners. To securely attach the anchor, you’ll need a screwdriver.

For mounting a TV, we recommend the Phillips screwdriver.

Things to Look for When Mounting a TV

Before we start the TV mounting process, let’s go through some key points beforehand.

Do You Want a Flexible Mount?

There are different mounting panels available on the market, fixed and moveable. You should choose one according to your needs.

Assume you want to watch TV while sitting on the sofa, but you also don’t want to skip your favorite program while in the dining room.

However, your Television cannot be in two places at the same time.

Installing a rotating TV mount will be equivalent to having a TV in two areas simultaneously!

Using the moveable panel, you may even have a TV that moves up to 20 inches from its initial position. If your Television is already at the ideal height and does not need to be adjusted, a fixed mount panel is a better alternative for you.

What Should You Do If The Stud Finder Doesn’t Work?

Electric stud finders might be challenging to use at times. If you don’t know how to utilize them correctly, they may show you misleading warnings.

To be most accurate, move carefully over the wall and let the stud finder read the density as you go.

Begin in one position and travel back and forth across the hanging spot a few times. Then, using a painter’s tape or pencil, identify each stud location before moving on to the next.

Are The Cords Visible?

You want your new TV to appear decent.

So, if a tangle of the cord is visible in front of the TV, it will look not pleasant! To keep the cords concealed, we recommend utilizing an in-wall power extender to conceal all the TV’s signal wires.

How To Mount a TV On a Plaster Wall?

Step 1: Select where you want to hang the TV

It would be best if you placed the television at eye level. Bigger screen sizes are better viewed at a higher position.

Check to see if there is a power socket nearby.

Step 2: Find the Wall Studs

Holding the stud finder flush against the wall will help you find the studs.

When the detector beeps, indicate the position of that stud and go on to the next. You can mark the spot with a pencil to help you remember the spot.

Step 3: Align the Mount

Now you should align the mount. To simplify your job, we recommend utilizing a carpenter’s leveling device (a tool used to determine whether an object is parallel to the earth).

Check that the mount’s top and bottom edges are parallel to the floor.

Step 4: Mark The Necessary Holes

Look for holes while holding the mount tight against the wall. Please remember that most mounts have 4/5 holes, and you must check that all screws are aligned with the studs.

With a marker, identify the screw holes.

Step 5: Decide on a Plaster Anchor

For a typical TV, use a plaster anchor that can support at least 150 pounds.

If you believe your TV is larger than usual, the anchor strength should be the total weight of the TV, the mounting panel, and an additional 20% on overall weight for safety.

Step 6: Drill Your Pilot Holes

Drill pilot holes into the wall with a masonry drill bit. The drill bit size should be at minimum 0.32-centimeter smaller than the anchor.

Drill thru the previously created marks, making sure the holes are big enough to support the wall anchors.

Step 7: Insert the Anchors

Depends on the sort of anchors you’ve used, you may need to screw the anchor into the wall with an electric screwdriver.

Step 8: Take the Screws Out of the Anchor

If you’ve used toggle bolts, you may skip this point and go straight to the next.

Remove the screws with the help of a screwdriver. The anchors remain intact once the screws are removed from the wall.

Step 9: Screw The Mounting Plate Into The Wall

Slide the anchor screws into the wall through the mounting panel.

Tighten the screws in place so that they are flat against the wall.

Check to see if the plate is correctly placed.

Step 10: Fasten the Mounting Plate to the TV

Place the TV on a level place so that it does not get damaged.

Remove any plastic covers from the back and screw them to the mounting panel by rotating them clockwise.

Request your housemate to raise the TV and align the plate with the mounting panel.

Step 11: Hang Your TV To The Wall

Mount the TV on the wall plate and make sure it’s in the middle position.

Try pushing the unit from both sides to verify whether everything is in place. If it’s steady, your job is completed! If not, go over each step again and study the TV’s guidebook to know more about it.

How Do You Mount A TV Without Studs On A Plaster Wall?

Tips for Mounting Your TV in the Most Convenient Way

Before installing your TV, ensure that the mount style is suitable for the model of your TV. If you want, you may also obtain a universal model.

It is possible to drill into the wrong place by accident. If this occurs, use a plaster patch to fill the hole.

Before hanging the TV, ensure all the electronic components are properly connected and that you work out a way to conceal any visible wires to get a flawless look.

Get a bit longer cables; it’s always better. If you have a hanging cable, you can always fold it and hide it in the wall.

Before drilling holes on the wall, make sure your TV is perfectly aligned.

Before installation, read the TV guidebook and, if necessary, get expert assistance.

Final Words

Poor hanging can damage your TV or, worse, cause permanent damage to the wall.

However, if the mounting panel is firmly attached to the wall, it will last a lifetime.

Hopefully, by reading this article, you’ve learned how to mount a TV on a plaster wall and enabled you to watch your favorite shows without risking harm to your TV or wall.

Remember, you’re not a professional, and it can take you about half an hour to finish the overall process. So, plan your time appropriately, be patient, and you’ll be able to mount your TV from start to finish on your own!

  1. How do you mount a TV on a plaster wall without studs?

To hang a TV without studs, use a toggle bolt or a toggle anchor. You’ll need a hollow wall anchor that looks like a standard screw and has a butterfly toggle at the end. They’ll attach to the back of the wall once you’ve installed them.

  1. How much weight can I hang on a plaster wall?

Metal toggle bolts can support (25 to 50 pounds) in drywall, concrete block, and plaster. Plastic toggles can support modest weights (10 to 25 pounds) in plaster and drywall.
