Which product is used to protect outside corners of gypsum board panels?

• A. corner bead
• B. joint compound
• C. baseboard
• D. metal lath

Answer: (A)

The correct choice is corner bead, which is specifically designed for protecting outside corners of gypsum board panels. Corner bead provides a durable edge that helps to maintain the integrity of the wall corners, preventing damage from impacts and ensuring a clean, finished appearance. It is typically made of metal or plastic, offering additional strength and support for the corners of drywall installations. Joint compound is used for finishing the joints between drywall panels, providing a smooth surface but does not protect the corners themselves. Baseboard refers to the finish trim installed at the bottom of walls, and metal lath is used as a base for plastering or as reinforcement in stucco applications, but they do not address corner protection in drywall assemblies.
