Fix a Cracked Corner of a Drywall

The exact broken or need a repair thing in this image is a cracked corner of a drywall. This part appears to be damaged due to settling or moisture issues, and needs immediate attention to restore full functionality.

Tools needed:

* Drywall repair compound (also known as spackling compound)

* Sandpaper ( medium-grit and fine-grit)

* Paint (matching the original wall color)

* Drywall tape

* Mud pan

* Putty knife (1-2 inches wide)

* Corner bead (optional)

Step-by-Step Detailed Guide to Fix it:

  • Clean the area around the crack: Use a vacuum cleaner or a damp cloth to remove any debris or dust from the cracked area.
  • Assess the crack: Examine the crack to determine its depth and length. If the crack is shallow and only affects the surface, you can proceed with the repair. If it's deep or affects the structural integrity of the drywall, you may need to consult a professional.
  • Apply drywall repair compound: Use a putty knife to apply a small amount of drywall repair compound to the crack. Fill the crack completely, but avoid applying too much compound, as it can be difficult to sand down.
  • Smooth out the compound: Use the putty knife to smooth out the compound, feathering it out towards the edges so that it blends with the surrounding drywall.
  • Allow the compound to dry: Let the compound dry completely, according to the manufacturer's instructions, which can take anywhere from 30 minutes to an hour, depending on the type of compound.
  • Sand the area: Use a medium-grit sandpaper to sand the area, feathering it out towards the edges. Sand in a circular motion, applying gentle pressure.
  • Apply additional coats: If necessary, apply additional coats of compound, allowing each coat to dry before sanding.
  • Sand with fine-grit sandpaper: Once the final coat of compound is dry, use a fine-grit sandpaper to sand the area, feathering it out towards the edges.
  • Apply drywall tape: If the crack is located near a corner, apply drywall tape to reinforce the area. Press the tape firmly onto the drywall, making sure it's centered.
  • Apply a final coat of compound: Apply a final coat of compound over the tape, smoothing it out with a putty knife.
  • Paint the wall: Once the compound is dry, paint the wall with a coat of paint that matches the original color.

Tips and Warnings:

* Work in a well-ventilated area: When working with drywall repair compound, make sure you're in a well-ventilated area to avoid inhaling fumes.

* Use protective gear: Wear a dust mask and safety glasses when sanding to protect yourself from dust and debris.

* Avoid over-sanding: Be careful not to over-sand, as this can create a depression in the drywall.

* Match the paint color: Make sure to match the paint color exactly to avoid noticeable repairs.

* Consider consulting a professional: If the crack is large or affects the structural integrity of the drywall, consider consulting a professional for assistance.
