Drywall corners are prone to damage, especially in high-traffic areas. Whether it’s a small dent or a large hole, repairing drywall corners can be a daunting task. However, with the right tools and techniques, you can easily fix damaged drywall corners and restore them to their original condition. This article will provide you with a comprehensive guide on how to repair drywall corners, covering the materials you need, step-by-step instructions, and tips for achieving a professional finish.
Before you start repairing the drywall corner, you need to gather the necessary materials. You will need drywall joint compound, a joint knife, sandpaper, a spackling knife, and a putty knife. Additionally, you may need a damp sponge, a sanding block, and a respirator. Once you have all of the materials, you can proceed with the repair process.
The first step is to prepare the damaged area. Clean the area around the damage with a damp sponge and remove any loose debris. If the damage is a small dent, you can fill it with drywall joint compound using a spackling knife. For larger holes, you will need to cut a patch of drywall to fit the hole and then attach it using drywall screws. Once the patch is in place, you can apply drywall joint compound over it and smooth it out with a joint knife. Allow the joint compound to dry completely before sanding it smooth with a sanding block. Finally, apply a thin coat of spackling paste over the repaired area and sand it smooth. Once the spackling paste is dry, you can paint the repaired area to match the rest of the wall.
Tools for Drywall Corner Repair
Putty Knife and Spackle
A putty knife is a versatile tool used for applying and smoothing spackle, a paste-like substance that fills and conceals imperfections in drywall. Choose a putty knife with a flexible blade that conforms to the contours of the corner being repaired. Spackle can be purchased in pre-mixed containers or as a powder that needs to be mixed with water.
Sanding Sponge and Sandpaper
Sanding sponges are indispensable for smoothing the spackled area and achieving a seamless finish. They are available in various grits, with finer grits producing a smoother surface. Sandpaper can also be used, but it requires more effort and can be more difficult to control than sanding sponges.
Corner Applicator
A corner applicator is a specialized tool designed to apply joint compound and paper tape to drywall corners. It consists of a metal or plastic frame with a handle that guides the tape and compound into the corner. Corner applicators simplify the process and ensure a professional-looking finish.

Steps for Patching Small Holes
1. Inspect the Damage
Before starting the repair, assess the size and location of the hole. If it’s smaller than a quarter, you can simply patch it with a spackling paste. However, if the hole is larger, you’ll need to cut out the damaged area and install a patch.
2. Cut Out the Damaged Area
If the hole is larger than a quarter, cut out the damaged area using a sharp utility knife. To ensure a clean cut, use a straightedge to guide the knife. Cut the drywall about 1 inch beyond the edges of the hole, creating a square or rectangular opening. Score the drywall along the perimeter of the cut to make it easier to remove. Carefully chip away the damaged drywall, taking care not to damage the surrounding area.
Once the damaged drywall is removed, you’ll need to create a template for the patch. Trace the opening onto a piece of scrap drywall or cardboard. Use the template to cut a patch that is slightly smaller than the opening. Apply a thin layer of joint compound to the edges of the patch and insert it into the void.
3. Apply Joint Compound
Apply a thin layer of joint compound over the patched area, feathering the edges to blend it into the surrounding drywall. Use a wide putty knife to spread the compound smoothly, working from the center of the patch outward. Allow the joint compound to dry completely before sanding and painting.
Dealing with Larger Holes
When faced with larger holes in your drywall corner, a more comprehensive repair approach is required. Here’s a step-by-step guide to help you effectively repair these larger blemishes:
-
Remove Loose Drywall Pieces: Utilize a utility knife to carefully remove any loose or damaged pieces of drywall from the hole’s perimeter. Ensure you create a clean and flush surface for the patch.
-
Install Corner Bead: If the original corner bead was damaged, replace it by cutting a new piece to the appropriate length and securing it in place using drywall screws or paneling nails. Make sure to press the bead firmly into the corner joint.
-
Apply Joint Compound:
-
First Coat: Apply a thick layer of joint compound (mud) over the affected area, extending beyond the edges of the hole. Use a 6-inch taping knife or drywall trowel to smooth the mud, creating a consistent and relatively flat surface. Allow it to dry completely.
-
Second Coat: Once the first coat is dry, apply a second coat of joint compound, feathering the edges to blend it seamlessly with the surrounding drywall. Allow this layer to dry thoroughly as well.
-
Sand and Prime: After the second coat is dry, sand the patched area lightly with fine-grit sandpaper to remove any rough spots or excess mud. Prime the entire repair with drywall primer to prepare it for painting.
- Paint: Once the primer is dry, you can apply paint to match the surrounding wall or ceiling. It may require multiple coats to achieve full coverage and blend in the repair seamlessly.
Taping and Mudding the Patch
Once the patch is secured, it’s time to tape and mud it to seamlessly blend it with the existing drywall. Here’s a step-by-step guide:
Apply Joint Compound to the Patch
Using a putty knife, apply a thin layer of joint compound to the patch area. Spread it evenly to create a smooth surface.
Embed the Drywall Tape
Roll out a strip of drywall tape and center it over the patch and the joint between the patch and the existing drywall. Press the tape firmly into the joint compound using the putty knife.
Coat the Tape with Joint Compound
Apply a second layer of joint compound over the tape. This layer should be thicker than the first, extending about 6 inches beyond the edges of the patch. Use a wider putty knife to apply the compound smoothly.
Smooth and Feather the Edges
Using a damp sponge or a trowel, carefully smooth the joint compound along the edges of the patch. Feathered the compound to blend it with the surrounding drywall. This will prevent visible transitions.
Let it Dry
Allow the joint compound to dry completely. The drying time will vary depending on the thickness of the compound and the temperature. Once dry, lightly sand the patch area to create a smooth surface.
Add a Second and Third Coat
Apply a second and third coat of joint compound, letting each coat dry completely before applying the next. The goal is to build up the compound to match the thickness of the surrounding drywall.
Sand and Finish
Once the final coat of joint compound is dry, sand the patch smooth. Start with coarse-grit sandpaper and gradually move to finer grits until the patch blends seamlessly with the existing drywall. Prime and paint the patch to match the rest of the wall.
Finishing the Patch Surface
5. Sanding and Touching Up
Once the patch is fully dry, it’s time to sand it down to match the surrounding drywall. Use a fine-grit sanding sponge or sandpaper and lightly sand the area until it’s smooth. Be careful not to over-sand and damage the drywall.
After sanding, apply a touch-up coat of joint compound to any imperfections or seams. Let it dry completely, then sand again if necessary. Once the surface is smooth and even, you can apply a coat of primer and paint to match the rest of the wall.
| Sanding Tools | Grit |
|---|---|
| Sanding Sponge | Fine (120-150) |
| Sandpaper | Fine (150-220) |
Tips for Sanding and Touching Up:
* Use a light touch when sanding to avoid damaging the drywall.
* Sand in circular motions to create a smooth surface.
* If there are any deep scratches or imperfections, apply a second coat of joint compound before sanding.
* Allow ample time for the patch to dry before sanding or applying primer and paint.
* Use a primer suitable for drywall to prevent the patch from showing through the paint.
Repairing Cracked Corners

Using Joint Compound for Seamless Repairs
Repairing a Small Hole
For small holes up to 2 inches in diameter, you can use joint compound to patch the area. Apply a thin layer of joint compound over the hole, using a putty knife. Let the compound dry completely, then sand it smooth.
Repairing a Large Hole
For larger holes, you’ll need to use a drywall patch. Cut a piece of drywall that is slightly larger than the hole. Apply a layer of joint compound to the edges of the patch and press it into the hole.
Reinforcing the Patch
Once the patch is in place, you’ll need to reinforce it with fiberglass mesh tape. Apply a layer of joint compound over the tape and let it dry completely. Then, sand the area smooth.
Applying a Finish Coat
Once the reinforced patch is dry, apply a finish coat of joint compound over the entire area. Sand the area smooth, and then prime and paint it to match the rest of the wall.
| Hole Size | Materials | Steps |
|---|---|---|
| Small (up to 2 inches) | Joint compound, putty knife | Apply joint compound, let dry, sand smooth |
| Large (over 2 inches) | Drywall patch, joint compound, fiberglass mesh tape | Cut drywall patch, apply joint compound to edges, press into hole, reinforce with tape, apply finish coat |
Tips for a Seamless Repair
* Use a sharp knife to cut the drywall patch. A dull knife will tear the drywall and make it difficult to get a smooth finish.
* Apply thin layers of joint compound and let each layer dry completely before applying the next. This will prevent the compound from cracking.
* Sand the area smooth between each coat of joint compound. This will help to create a seamless finish.
* Prime the area before painting it. This will help to prevent the paint from absorbing into the drywall and creating a uneven finish.
Painting the Repaired Corner
Once the joint compound has fully dried, it’s time to paint the repaired corner. Here are the steps:
1. Clean the Area
Use a damp sponge or cloth to wipe down the repaired area. This will remove any dust or debris that could interfere with adhesion of the paint.
2. Prime the Area
Apply a coat of drywall primer to the repaired area. This will help to seal the joint compound and create an even surface for the paint.
3. Apply the First Coat of Paint
Using a brush or roller, apply a thin, even coat of paint to the repaired area. Allow the paint to dry completely before applying a second coat.
4. Apply the Second Coat of Paint
Once the first coat of paint is dry, apply a second coat. This will help to ensure that the repaired area is completely covered and matches the rest of the wall.
5. Touch Up
Once the second coat of paint is dry, inspect the repaired area for any imperfections. If any areas need additional touch-up, use a brush or roller to apply a small amount of paint.
6. Caulk the Corner
To prevent cracks from reoccurring, apply a thin bead of caulk to the corner where the drywall meets. Smooth the caulk with a damp sponge or finger.
7. Touch Up the Caulk
Once the caulk has dried, inspect it for any imperfections. If any areas need additional touch-up, use a damp sponge or finger to smooth them out.
