How to Repair Drywall Corner

Most drywall repairs, such as fixing problems on flat seams, are easy to do on your own. However, when it comes to repairing the corners, it becomes quite challenging.

Any inexperienced repairer is likely to make mistakes such as failing to use enough mud on this part or failing to scrape it off correctly. It results in visible air bubbles on the wall since the tape does not adhere well to rough surfaces. In this blog post, you will learn how to repair drywall corners.

Flatten your corner

Metal corners begin to warp with time. If you notice this, then reinforce the corner with nails.

Cut the required size of drywall

Once the corner is flat, prepare the desired size of drywall depending on the amount of repair needed.

Scrape the damaged part

It allows you to remove the drywall near the damaged corner, which might have been affected even though you can’t notice it. It will ensure that you fix the problem well.

Tape the corner

Tape provides a surface for the joint compound to adhere to. Cut the required size, then place it over the section making sure that it sticks firmly.

Apply joint compound

Using a putty knife, apply your drywall mud to the damaged corners over the tape. Use enough compound to fill the damage and feather the edges to the rest of the wall.

Sand the layer and apply another one

When dry, sand the layer to remove the rough residues, then apply another layer of the joint compound. This time, expand the layer past the previous one, then let it dry and sand it.

Finishing

Prime and paint your drywall corner and give it a nice finish that matches the rest of the wall.

Precautions

Apply mud in thin layers. Multiple thin layers are advised compared to thick ones, which are challenging to smoothen. Use at least three layers of joint compound for better results.

Always scrape off excess joint compound before going to the next step.

Before laying your mud, ensure that you have the correct size of tape in place. The longer the tape, the better.
