Corner bead
Corner bead is the metal or plastic strip used to create strong, straight outside corners in drywall.
Why it matters
It protects corners from damage and keeps lines crisp.
Where people get this wrong
Corner bead still needs good mud work to look straight. Corners can look wavy if bead is installed crooked.
Real-world example
A hallway corner gets bumped by a vacuum every week. Without solid corner bead and good mud, that corner turns into a dented mess.
Where this hits your build
This comes up during the finish phase. Lighting, angles, and personal expectations collide here. What looks fine at noon can look rough at dusk.
Most people do not just struggle with terms. They struggle with the decisions tied to them.
