A wall with a patch of newly-applied drywall compound

If you’ve ever hung a TV on your wall, you know that mounting it can be a tricky task. But what happens when you have to remove it? Chances are that you might end up with unsightly holes or damage to your wall. However, repairing wall damage after removing a TV mount is not rocket science, and you can do it yourself without calling a professional. In this article, we will take you through the steps of repairing your wall after removing a TV mount.

Tools Needed for Wall Repair

To get started with repairing your wall, you will need some tools. Here’s a list of what you’ll need:

  • Drywall saw or cutter
  • Putty knife
  • Sanding paper
  • Spackle or drywall compound
  • Paintbrush or roller
  • Primer and paint

Before you begin repairing your wall, it’s important to assess the damage. If the damage is extensive, you may need to call in a professional. However, if it’s a small hole or crack, you can easily fix it yourself with the right tools.

When purchasing your tools, make sure to choose high-quality ones that will last. It’s also important to wear protective gear, such as gloves and goggles, to prevent any injuries while working on the wall.

Understanding Different Types of Wall Damage

Before you start repairing your wall, it’s essential to understand the different types of wall damage you may encounter. The most common types are holes, cracks, and dents. A small hole is easy to repair, but if you have a larger hole or crack, you’ll need to put in more effort to fix it. Dents, on the other hand, can be tricky to repair as they often require sanding to the surface level.

Another type of wall damage that you may encounter is water damage. This can occur due to leaks or flooding and can cause discoloration, peeling paint, and even mold growth. It’s important to address water damage as soon as possible to prevent further damage and potential health hazards.

In addition to the types of damage mentioned above, walls can also suffer from wear and tear over time. This can include scuff marks, scratches, and fading paint. While these may not be as severe as other types of damage, they can still detract from the appearance of your walls. Fortunately, these issues can often be easily fixed with a fresh coat of paint or touch-up work.

Preparing the Surface for Repair

The first step in repairing a damaged wall is to prepare the surface. Start by scraping off any loose debris, dust, and dirt around the area. Then, use a sandpaper to smooth out any rough edges. After you’ve cleaned the surface, wipe it off with a damp cloth and let it dry before moving on to the next step.

It’s important to note that if the damaged area is large or if there are cracks in the wall, you may need to use a joint compound to fill in the gaps. Apply the joint compound with a putty knife, making sure to smooth it out evenly. Allow the compound to dry completely before sanding it down to create a smooth surface. Once the surface is smooth and free of any debris, you can move on to painting or applying a new layer of wallpaper.

Repairing Small Holes in Drywall

If you have a small hole in your drywall, you’ll need to fill it with spackle or drywall compound. Start by scooping out the spackle or drywall compound and apply it to the hole using a putty knife. Make sure that you fill the hole entirely and that the surface is smooth and level. Allow the spackle or drywall compound to dry, and then sand it smooth with fine-grit sandpaper.

It’s important to note that if the hole is larger than a quarter, you may need to use a drywall patch to cover the hole before applying the spackle or drywall compound. To do this, cut a piece of drywall slightly larger than the hole and place it over the hole. Secure the patch in place with drywall tape and apply the spackle or drywall compound over the patch.

After sanding the repaired area, you may need to prime and paint the wall to match the surrounding area. It’s best to use a paintbrush or roller to apply the paint, and to apply multiple coats if necessary to achieve a seamless finish.

Fixing Large Holes in Drywall

Large holes in drywall are a bit more complicated to fix, but the process is the same as for small holes. Use a drywall saw or cutter to cut out the damaged portion of the wall, leaving behind a rectangular hole. Cut a piece of drywall that fits the hole, and attach it to the wall using screws or adhesive. Once the drywall is secured in place, use spackle or drywall compound to fill the gaps around the edges. Sand the surface smooth before moving on to the next stage.

It’s important to note that for larger holes, you may need to add additional support behind the drywall patch. This can be done by attaching a piece of wood or metal to the inside of the wall, spanning across the hole, and then attaching the patch to that support. This will ensure that the patch stays securely in place and doesn’t sag or shift over time.

If you’re not confident in your ability to fix a large hole in drywall, it’s always best to call in a professional. They will have the tools and expertise needed to make sure the repair is done correctly and looks seamless. Plus, they can often complete the job much more quickly than a DIYer, which can save you time and hassle in the long run.

Patching Cracks in Plaster Walls

If you have an older home, your walls may be made of plaster instead of drywall. Repairing cracks in plaster walls is different from repairing drywall. Start by using a utility knife or scraper to remove any loose plaster around the crack. Next, apply a coat of joint compound to the crack using a putty knife. Be sure to spread the joint compound evenly, covering the entire length of the crack. Allow the compound to dry, and then sand it smooth. Repeat the process until the crack is completely filled and level with the rest of the wall.

It is important to note that if the crack is particularly large or deep, you may need to use a plaster patching product instead of joint compound. These products are specifically designed for repairing plaster walls and can provide a stronger, more durable repair. Follow the manufacturer’s instructions carefully when using these products.

After the crack has been repaired, you may need to touch up the paint or wallpaper on the wall. If the wall has been painted, use a paintbrush to carefully apply paint that matches the existing color. If the wall has wallpaper, you may need to carefully cut out a small section of the wallpaper and replace it with a matching piece.

Removing Loose Plaster and Repairing the Surface

If you have loose plaster on your walls, it’s important to remove it before repairing the surface. Use a putty knife or scraper to remove any loose plaster from the wall. Once you’ve removed all the loose plaster, apply a coat of joint compound to the surface using a putty knife. Spread it evenly to make the surface level. Allow it to dry, and then sand the surface smooth. Repeat this process as needed until the surface is smooth and free of any bumps or imperfections.

It’s important to note that if you have a large area of loose plaster, it may be necessary to hire a professional to repair the wall. Attempting to repair a large area on your own can be time-consuming and may not result in a satisfactory outcome. Additionally, if the plaster is very old, it may contain hazardous materials such as asbestos, which can be dangerous if inhaled. In this case, it’s best to hire a professional who has the necessary equipment and expertise to safely remove the plaster.

Once the surface is smooth and free of any imperfections, you can paint or wallpaper the wall as desired. If you’re painting the wall, be sure to use a primer before applying the paint. This will help the paint adhere to the surface and ensure a smooth, even finish. If you’re wallpapering the wall, be sure to use a wallpaper primer before applying the wallpaper. This will help the wallpaper adhere to the surface and prevent it from peeling or bubbling over time.

Sanding and Smoothing the Repaired Area

After you have repaired the wall and patch, it’s time to sand and smooth the surface to make it ready for painting. Start by using a fine-grit sandpaper to remove any bumps or rough edges. Then, use a damp cloth to wipe off any dust or debris from the surface. Allow it to dry completely before moving on to the next stage.

Painting Over the Repaired Wall Surface

Now that your wall is smooth and free of any damage, it’s time to paint it. Apply a coat of primer to the surface, let it dry, and then apply your paint of choice. Be sure to use a paintbrush or roller to apply the paint evenly and in a single direction. Allow the paint to dry before applying a second coat if needed.

Tips for Preventing Wall Damage in the Future

To prevent wall damage in the future when removing a TV mount, instead of drilling directly onto the wall, use wall mounts that are designed to attach to the studs. This distributes the weight evenly, reducing the chances of damage to your wall.

Common Mistakes to Avoid While Repairing Walls After Removing a TV Mount

One of the most common mistakes people make while repairing walls after removing a TV mount is not investing enough time in preparing the surface. If you don’t clean and patch the surface correctly, your repair job will not last. Similarly, using too much spackle or joint compound can result in a lumpy and uneven surface. Be sure to apply only as much as needed, and sand the surface after every coat.

When to Call a Professional for Wall Repair

If you have a large hole in your wall or damage to your plaster walls, it’s best to call a professional for help. They have the experience and expertise needed to ensure that your wall is repaired correctly and that it lasts for a long time.

Cost Breakdown of DIY Vs Professional Repairs

The cost of repairing your wall after removing a TV mount varies depending on the extent of the damage and whether you decide to do it yourself or hire a professional. DIY repairs usually cost less, with the only expense being the cost of materials. Professional repairs, on the other hand, can be more expensive due to labor costs. Consider your budget and the extent of the damage before deciding who to hire.


Repairing your wall after removing a TV mount may seem daunting at first, but it’s a task that you can undertake yourself with a little bit of patience and effort. Remember to prepare the surface correctly, use the right tools and materials, and take your time throughout the process. With these steps in mind, you can have a repaired wall that looks good as new.
