5 Steps to Fix Uneven Drywall Seams

Uneven drywalls may look ugly and annoying. But fixing the problem is not so hard. Keep in mind the amount of weight the drywall can hold.

You can do it on your own. Here we’ve described how to fix uneven drywall seams in 5 easy steps. The steps are as follows-

Step 1 of 5: Cleaning the Wall

Before you start to work, your wall should be clean. There should be no dust or other residues on the wall.

For cleaning the wall, you can use soap and water or any other cleaning substance. But keep in mind that the cleaning should not make your wall condition worse. For example, don’t soak your wall in the water. Or else, there will be water clogged in your basement and floor.

Step 2 of 5: Sanding the Wall

In this step, use sandpaper. I prefer 120-grit sandpaper to remove the bumps and additional residues. A sanding pole can be handy while sanding higher places or the ceiling.

Applying a primer after sanding the wall properly is greatly encouraged. But make sure you’re not choosing the white primer.

Step 3 of 5: Applying First Coat of Drywall Compound

Now it’s time to do the main work. Store drywall compound in a pan. After that, scoop a mound of drywall compound on the edge of a tapered knife.

Fill the gaps which are making the drywall look uneven using the drywall compound. Spread the compound evenly by pressing it. Fill in the largest gaps on the first attempt.

Don’t apply too much drywall compound at the first go and allow it to dry.

Step 4 of 5: Applying Drywall Compound Completely

Apply a broad layer of drywall compound throughout the entire surface. Use the knife to apply the compound properly. Press the areas where the compound dips in and fill them accurately.

Remove the excess compound with the knife and restore them to the pan. Remove the compound from the knife’s edges as well and make it clean. 

After that, run the flat side of the knife. Run it across the wet compound to smoothen the surface.

Make the transition between the existing wall and drywall compound smooth. Finally, allow the wet compound to dry.

Step 5 of 5: Finishing Up

As you’ve done the hard work, now it’s time to wrap up and finish the project. Take a sanding sponge and dampen it.

Rotate the sponge in a circular pattern along the drywall compound area. Make the drywall compound area smoother and blend the edges. If there’s any uneven peak on the drywall compound applied area, flatten it with a sponge.

Thus finish the work of fixing uneven drywall seams.

If you are also interested in constructing a new wall, you can look into plaster alongside drywalls.

Safety Measures

Getting hurt while fixing your uneven drywall isn’t something you want to face. Maintaining safety is always important.

While working, follow the safety measures stated below:

  • Use hand gloves while working. Or else your skin can get exposed to chemical substances.
  • Carefully, use the knife. Don’t hurt your hands while operating the knife on the surface.
  • Sandpaper can be rough on your skin. So, use that carefully.
  • Make sure that you’re using a good quality product. Otherwise, it will not fulfill the purpose.
  • Don’t forget to have alternative arrangements like a temporary shower if you’re working in your bathroom.

Follow these safety guidelines to keep yourself out of danger.
