1. Preparation

Start by preparing the area around the damaged corner. Remove any furniture or objects that may obstruct your work. Use a screwdriver or hammer to remove any loose nails or screws, and clean the surface with a damp cloth to remove dust and debris.

2. Apply Drywall Patch or Mesh Tape

For minor cracks or holes, you can use a drywall patch or mesh tape to reinforce the area. Cut the patch or tape to the appropriate size and apply it over the damaged corner, ensuring it covers all the cracks or holes.

3. Apply Joint Compound

Using a joint knife, apply a thin layer of joint compound over the drywall patch or mesh tape, smoothing it out as you go. Let the first layer dry completely before applying a second layer, which should be feathered out slightly beyond the patch or tape.

4. Sanding and Priming

Once the joint compound is completely dry, sand it smooth using fine-grit sandpaper. Remove any dust or debris from the sanded area. If necessary, apply a primer to match the existing wall surface.

5. Painting or Wallpapering

Once the primer is dry, you can paint or wallpaper the repaired corner to match the surrounding wall. Use a high-quality paint brush or roller for painting, or follow the manufacturer’s instructions for wallpaper application.

Tips and Expert Advice

  • If the damage is extensive or structural, consider consulting with a professional contractor to ensure proper repair and prevent further issues.
  • For deeper cracks or holes, you can use spackling paste before applying the joint compound for a more durable repair.
  • Use a sanding block for sanding to achieve a smooth, even finish.
  • Allow ample time for each layer of joint compound to dry completely before sanding or applying another layer.
  • If the wall is textured, match the texture by gently dabbing a sponge into the joint compound while it’s still wet and then smoothing it out.
