What is a Corner Bead and Why Does It Need Repairing?
In the realm of home improvement and drywall installation, a corner bead refers to a pre-formed metal or vinyl piece used to protect the exterior corners of drywall.
Purpose of Corner Beads
The main function of a corner bead is to provide a seamless and tidy finish to the edges where two pieces of drywall meet. It hides sharp corners and creates a smooth line, preventing unwanted injuries while also reinforcing the drywall against damage.
Common Damages to Metal Corner Beads
Metal corner beads can be damaged by harsh impacts, moisture or improper installation. Common signs of a damaged drywall corner bead include peeling paint, cracked or chipped compound covering the bead or the metal bead itself getting bent or rusted.
Tools and Materials Needed for Metal Corner Bead Repairs
Before starting repairs, you'll need to gather some essential tools and materials.
Oscillating saw: This will be used to help you access the damaged corner bead.
Utility knife: This is used for cutting away the loose or damaged parts of the drywall corner bead.
Putty knife: Use a putty knife or taping knife to apply joint compound. You can also use it to remove peeling paint or wallpaper.
Drywall screws: These screws are necessary for securing the new corner bead in place.
Drywall nails: Nails are another option for securing the corner bead. However, screws are often preferred due to their stronger holding power.
New corner bead: When metal corner beads are damaged, they cannot be repaired. You'll need to purchase a new bead as a replacement. You can replace it with a new metal bead or a vinyl bead. It might be a good idea to switch to vinyl due to its durability, impact resistance, and ease of repair.
Drywall compound: Commonly known as joint compound or “mud,” it’s used to cover the screws and smooth out the repaired area.
