How to Repair Drywall Outside Corners

Drywall outside corners are prone to damage from impacts, moisture, and other factors. Repairing them promptly is essential to maintain the structural integrity of your walls and prevent further damage. There are a few essential aspects to consider when repairing drywall outside corners: preparing the surface, applying joint compound, and finishing the repair.

Preparing the Surface

Before you can repair the damaged corner, you need to prepare the surface. This involves removing any loose or damaged drywall, cleaning the area, and applying a bonding agent to help the new joint compound adhere properly. Use a utility knife to carefully cut away any damaged drywall, being sure not to damage the surrounding area.

Applying Joint Compound

Once the surface is prepared, you can apply joint compound to the damaged area. Use a putty knife to apply a thin layer of joint compound to the corner, and then press a corner bead into the joint compound. The corner bead will help to reinforce the corner and prevent future damage. Allow the joint compound to dry completely before sanding it smooth.

Finishing the Repair

Once the joint compound is dry, you can finish the repair by applying a second coat of joint compound and sanding it smooth. Use a fine-grit sandpaper to sand the area until it is flush with the surrounding drywall. You may need to apply multiple coats of joint compound and sand it between each coat to achieve a smooth finish.

Repairing drywall outside corners is a relatively simple process that can be completed in a few hours. By following these essential steps, you can ensure that the repair is durable and aesthetically pleasing.
