How to Fix a Drywall Crack

Apr 4

Don't panic if you notice a crack in your drywall. Your house won't be falling apart.

Actually, small drywall cracks, which are common in settling houses, can often be caused by house movement. They're also very easy to fix.

Instead of hiring a professional to fix your drywall crack, you can use this guide.

The Tools That You Will Need

Before you can get started, make certain you have the right tools.

If you are trying to use "supplement tools" from other tools around your home, you won't make the project any farther before you need to stop buying the right tools.

Here are some things that you will need.

  • Utility Knife
  • 6-inch Taping knife
  • Mud pan (you don’t necessarily need a mud pan, but it will help you apply drywall compound using the taping knives.
  • Drywall compound
  • Fine-grit, sandpaper
  • Fiberglass drywall tap is thicker than paper drywall tape and can be difficult to fix visually. For this guide, we will only be focusing on paper-based drywall tape.

Step 1.

You must first clean out the crack. You can use your utility knife to trim any edges or scrape any debris from the crack.


Place some of the compounds in the mud pan. Tape the knife to apply a small amount. Then, apply a thin coat to the crack.


Use enough tape to cover cracks. You can use small pieces to cover odd-shaped cracks.

Then, apply the tape to the drywall compound. The tape should be applied as quickly as possible after the compound has been applied.

If the crack is unusually long, you may need to cut the tape prior to applying the compound.


Tape the drywall tape to the compound using the knife.

You should make sure that there are no bubbles. Any air that is under the drywall tape will stick there forever and create a little bump in your wall. You should make sure that there are no bubbles. If there are bubbles

Cover the tape with another layer and wait for it to dry. The drying process can take up several hours or even overnight.


You can apply a second coat on top. The compound should blend in with the wall's edges. The compound shouldn't be layered too thick, as it can cause wall cracks.


Apply the third coat once the second coat has dried. Let it dry again.

Step 7

Your fine-grit Sandpaper should be used to smoothen the drywall compound. However, do not sand right to the drywall tape.

Once you're done with sanding, it is possible to repaint your patch with the same color as the rest. Make sure to apply primer before you start sanding.

If you don’t, the color won’t match your wall perfectly.

All it takes to fix drywall crack

The most challenging part of this job is waiting for all the layers on the ceiling to dry. Other tasks are easy to do and don't require too much work.
