DIY steps
- Turn off the electricity to the area and ensure the drywall is free from any obstructions. Wear a dust mask and safety goggles to protect yourself from dust and debris. Use a putty knife to scrape away any loose or crumbling drywall around the crack.
- Apply a thin layer of joint compound to the crack, spreading it smoothly with the putty knife. Press drywall tape firmly onto the compound, ensuring it's centered over the crack. Use a putty knife or taping knife to press the tape firmly onto the drywall, removing any air bubbles or excess compound.
- Allow the compound to dry completely, according to the manufacturer's instructions, usually 30 minutes to an hour. Use a sanding block or sandpaper to sand the area smooth, feathering the edges so the repair blends with the surrounding drywall.
- Apply a second coat of joint compound, spreading it smoothly with the putty knife. Allow it to dry, then sand the area again, feathering the edges for a seamless finish.
- Use a paint brush to apply a coat of primer to the repaired area, if necessary, and allow it to dry. Finish by painting the wall with a coat of paint that matches the surrounding area.
- Clean up the area, disposing of any leftover materials and washing your tools with soap and water.
