Corner damage in drywall can be a common occurrence, especially in high-traffic areas or rooms with frequent movement. Whether it’s a small nick or a large hole, these blemishes not only affect the aesthetics of your space but also compromise the structural integrity of the drywall. Fortunately, repairing corner drywall damage is a relatively simple task that can be completed with basic tools and materials. By following a few basic steps, you can effectively conceal the damage and restore the corner to its original condition, leaving you with a smooth and flawless surface once again.
To begin the repair process, you will need to gather some essential tools and materials. These include a drywall knife, drywall tape, drywall compound (also known as spackling paste), a sanding sponge or sandpaper, and a paintbrush or roller. Once you have your materials, you can start by cleaning the damaged area to remove any debris or loose pieces of drywall. Next, apply drywall tape over the crack or hole, ensuring that it is centered and extending at least 2 inches beyond the edges of the damage. Use a drywall knife to press the tape firmly into place, smoothing out any air bubbles or wrinkles.
Once the drywall tape is applied, you can start filling the gap with drywall compound. Use a drywall knife to apply a thin layer of compound over the tape, smoothing it out evenly. Allow the first coat to dry completely, then apply a second coat, feathering the edges to blend it seamlessly with the surrounding drywall. Once the second coat is dry, sand the area smooth using a sanding sponge or sandpaper. Finally, apply a primer and paint to match the rest of the wall, and your corner drywall repair will be complete.
Inspect the Damaged Area
Before embarking on repairs, it is crucial to meticulously assess the extent of drywall damage. This thorough inspection will provide valuable insights into the appropriate repair strategy and ensure a successful outcome.
Assessing Damage Severity
Begin by determining the severity of the damage. A mild dent or small crack may require only minor patching, while a gaping hole or severe buckling may necessitate more extensive repairs.
Evaluating Moisture
Moisture is a common culprit behind drywall damage, so it is essential to check for its presence. Moisture can soften the drywall, making it more susceptible to damage and creating an environment conducive to mold growth.
Locating Studs
Identifying the studs behind the drywall is essential for proper repairs. Studs provide support to the drywall and serve as anchors for fasteners. Use a stud finder or knock on the wall to locate them.
Remove the Damaged Drywall
Removing the damaged drywall is a crucial step in the process of repairing a corner drywall. Follow these steps to do it properly:
1. Remove Fixtures and Trim
Before you start removing the drywall, you need to remove any fixtures or trim that are attached to it. This includes things like electrical outlets, light switches, and baseboards. Use a screwdriver or drill to remove the screws that are holding them in place.
2. Cut Out the Damaged Drywall
Once you have removed the fixtures and trim, you can start cutting out the damaged drywall. Use a utility knife to score the drywall along the edges of the damaged area. Then, use a drywall saw or a hand saw to cut out the drywall.

3. Remove the Nails or Screws
Once you have cut out the damaged drywall, you need to remove the nails or screws that are holding it in place. Use a screwdriver or drill to remove the nails or screws. Be careful not to damage the studs behind the drywall.
Cut and Install a Patch
To cut and install a patch for a damaged corner, follow these steps:
- Cut a square or rectangular patch from a piece of scrap drywall that is larger than the damaged area.
- Score the edges of the patch around the perimeter with a utility knife to create a bevel.
- Apply a liberal amount of drywall joint compound to the edges of the patch, as well as to the damaged area of the corner.
- Position the patch over the damaged area and press it firmly into place, ensuring that the edges are flush with the surrounding drywall.
- Use a putty knife to smooth out the joint compound and feather the edges of the patch.

- Sand the repaired area smooth and apply a coat of paint to match the surrounding wall.
- Attach the sandpaper to the sanding block or sponge.
- Gently sand the patch in a circular motion.
- Be careful not to sand too aggressively, as this can damage the drywall.
- Once the patch is smooth, vacuum the dust from the area.
- Use a brush to apply a thin coat of primer to the repaired area. This will help the paint adhere better.
- Allow the primer to dry completely.
- Apply a thin coat of paint to the repaired area. Use a brush or roller, depending on the size of the area.
- Allow the first coat of paint to dry completely.
- Apply a second coat of paint. This will help to ensure that the repaired area is fully covered and matches the rest of the wall.
- Allow the second coat of paint to dry completely.
- Once the repaired area is dry, it should be indistinguishable from the rest of the wall.

Tips for painting the repaired area: Use a high-quality paint that is compatible with the type of paint used on the rest of the wall. Apply the paint in thin, even coats. Allow each coat of paint to dry completely before applying the next coat. If the repaired area is large, you may need to apply multiple coats of paint. Repairing a Large Hole
Repairing a large hole in the corner of a drywall requires additional steps compared to smaller holes:
9. Apply a Joint Compound Layer
After the patch has been secured, you need to apply a thin layer of joint compound over the patch and the surrounding area, smoothing it out with a putty knife.
The recommended thicknesses for each layer:
Layer Thickness First Layer 1/16 – 1/8 inch Second Layer (optional) 1/16 inch Let the compound dry completely.
Once the compound is dry, apply a third, thicker layer over the patch and surrounding area. Smooth it out, feathering the edges. Let this layer dry completely.
Sand the patched area smooth, starting with a medium-grit sandpaper and gradually progressing to finer grits.
Wipe the area clean, prime it, and paint it to match the rest of the wall.
Preventative Maintenance
When hanging drywall, several steps can be taken to prevent the corners from cracking or breaking in the future:
- Use proper joint tape: Self-adhesive fiberglass mesh tape is the strongest and most durable type of joint tape for drywall corners.
- Apply joint compound liberally: Don’t skimp on the joint compound. Apply it liberally to the corner, making sure to fill in any gaps or voids.
- Embed the joint tape: Press the joint tape firmly into the joint compound, making sure that it is completely embedded.
- Allow the joint compound to dry thoroughly: Before sanding or painting, allow the joint compound to dry thoroughly. This will help to prevent the corner from cracking or breaking.
- Sand the joint smooth: Once the joint compound is dry, sand it smooth. This will help to create a smooth, even surface.
- Prime the joint: Before painting, prime the joint with a drywall primer. This will help to seal the joint and prevent the paint from cracking or peeling.
- Paint the joint: Once the primer is dry, paint the joint with a high-quality paint. This will help to protect the joint from damage.
- Inspect the joint regularly: Once the joint is finished, inspect it regularly for any signs of damage. If you notice any cracks or breaks, repair them immediately.
- Use a corner bead: When installing drywall, it is a good idea to use a corner bead to protect the corners from damage. Corner beads are thin metal strips that are installed over the drywall corners and help to reinforce them.
- Use a drywall corner trowel: When taping and mudding drywall corners, use a drywall corner trowel. Drywall corner trowels are designed specifically for taping and mudding corners and help to create a smooth, even finish.
How To Fix A Corner Drywall
Fixing a corner drywall is a simple repair that can be done in a few steps. First, you will need to remove the damaged drywall. To do this, use a utility knife to score the drywall along the edge of the corner. Then, use a pry bar to remove the drywall. Once the drywall is removed, you will need to cut a new piece of drywall to fit the corner. To do this, measure the length of the corner and cut a piece of drywall that is the same length. Then, apply a thin layer of joint compound to the edge of the new drywall. Place the new drywall in the corner and press it into place. Once the drywall is in place, you will need to apply a second layer of joint compound to the corner. Use a putty knife to spread the joint compound evenly over the corner. Once the joint compound is dry, you can sand it smooth. Finally, you can paint the corner to match the rest of the wall.
