Where should gypsum board panels be protected at outside corners?

Gypsum board panels are particularly vulnerable at outside corners due to their exposure to potential impacts and wear. Protecting these corners is essential to maintain the integrity and appearance of the finish. Using a corner bead is the best method for this protection. A corner bead is specifically designed to reinforce the edges of the gypsum board at outside corners, providing a strong, durable barrier that can withstand bumps and dings.

The corner bead not only adds strength but also helps create a clean, straight edge for finishing. It can be made from various materials, including metal or plastic, which further enhances its protective qualities.

Other methods, such as using tape and compound, might help secure seams and joints but do not provide the same level of protection specifically at outside corners. Extra screws and dual layers, while they might add stability in some contexts, do not address the unique vulnerabilities of outside corners in the same effective manner as a corner bead does.
