How to fix a dent in the wall

It’s happened to all of us – you’re moving furniture around your home and accidentally bump into the wall, leaving a noticeable dent. Or maybe you have young children who like to play rough and accidentally create dents in the wall while running around. No matter how the dent got there, it’s an eyesore and can lower the overall aesthetic of your home.

Don’t despair – fixing a dent in the wall is a relatively simple task that can be accomplished with a few household tools and a bit of elbow grease. In this blog post, we’ll go over the step-by-step process of how to fix a dent in the wall so you can get your home looking pristine once again.

Assessing the Damage

The first step in fixing a dent in the wall is to assess the damage. Take a close look at the dent and determine how deep it is and whether there are any cracks or chips in the paint. If the dent is shallow and there is no damage to the paint, you can probably fix it using a few simple techniques that we’ll outline below.

If the dent is deeper or there is damage to the paint, you may need to take more drastic measures such as patching the hole or repainting the affected area. In this case, it may be best to seek the help of a professional.

Gather Your Tools

Once you’ve assessed the damage, it’s time to gather the tools you’ll need to fix the dent. Here’s a list of what you’ll need:

  • A hair dryer
  • A can of compressed air (such as the kind used to clean computer keyboards)
  • A plunger
  • A putty knife or spatula
  • Sandpaper
  • Paint and paintbrush (if necessary)

Step 1: Heat It Up

The first technique for fixing a dent in the wall involves using heat to soften the paint and wall material. This is a good option for dents that are shallow and don’t have any damage to the paint.

To start, grab your hair dryer and set it to the highest heat setting. Hold the dryer about six inches away from the dent and aim the heat directly at it. After a few minutes, the heat will soften the paint and wall material, allowing you to push the dent out with your finger or a spoon.

Step 2: Use Compressed Air

If the heat method doesn’t work, or if you don’t have a hair dryer, you can try using compressed air to remove the dent. This method works best on shallow dents with no paint damage.

To start, shake the can of compressed air well and hold it about six inches away from the dent. Aim the nozzle at the dent and spray a burst of air directly at it. The pressure from the air should push the dent out.

Step 3: Use a Plunger

If the heat and compressed air methods don’t work, or if you have a deeper dent, you can try using a plunger to remove it. This method is a bit unconventional, but it can be surprisingly effective.

To start, wet the plunger and place it over the dent. Push down on the handle to create suction, then pull the plunger up and away from the wall. The suction from the plunger should help to lift the dent out of the wall.

Step 4: Use a Putty Knife or Spatula

If the dent is still stubborn and won’t budge with the heat, compressed air, or plunger methods, you can try using a putty knife or spatula to gently pry it out. This method works best on shallow dents that have a bit of give to them.

To start, gently insert the putty knife or spatula under the edge of the dent and gently pry upwards. Use a sawing motion to work the dent out of the wall, taking care not to damage the paint or wall material.

Step 5: Sand and Repaint

If you were unable to remove the dent completely or if there is damage to the paint, you may need to sand the affected area and repaint.

To start, use sandpaper to smooth out any rough or uneven areas. Wipe down the area with a damp cloth to remove any dust or debris. Then, apply a coat of primer to the area and allow it to dry completely. Finally, apply a coat of paint that matches the rest of the wall.


Fixing a dent in the wall may seem daunting at first, but with the right tools and a bit of patience, it can be a relatively simple task. Whether you use heat, compressed air, a plunger, or a putty knife, there are several techniques you can try to remove dents from your walls. And if all else fails, sanding and repainting is always an option. With these tips in mind, you’ll be well on your way to fixing those pesky dents and keeping your home looking its best.
