DIY steps
- Turn off the power to any nearby outlets or switches, and verify the area is clear of debris. Wear a dust mask and safety glasses to protect yourself from joint compound and drywall dust. Use a putty knife to scrape away any loose or damaged joint compound around the corner bead.
- Use tin snips to carefully cut the old corner bead away from the drywall, taking care not to gouge the surrounding surface. Remove any remaining adhesive or debris with a putty knife.
- Cut a new corner bead to the correct length using tin snips, and apply a thin layer of joint compound to the back of the bead. Press the bead firmly into place, ensuring it's centered and even.
- Use drywall screws to secure the corner bead to the surrounding drywall, spacing them about 6 inches apart. Apply additional joint compound around the bead, feathering it out towards the edges.
- Allow the joint compound to dry completely, according to the manufacturer's instructions. Use a sanding block or sandpaper to smooth out the area, feathering the edges so the repair blends in with the surrounding surface.
- Apply a second coat of joint compound if necessary, and allow it to dry before sanding again. Use a vacuum cleaner or damp cloth to remove any dust or debris from the area.
- Inspect the repair to ensure the corner bead is secure and the joint compound is smooth and even. Touch up any imperfections with additional joint compound or paint.
