Intruduction:
The AE Corner bead is attached to the corner of two adjacent walls. The AE Corner bead is a long strip of rectangular building material bent along the center, lengthwise, typically at a 90-degree angle.The AE Corner bead gives the corner a crisp appearance by covering the gap between the two sheets of drywall that meet from each wall. Plaster mud is then spread over the drywall and corner bead to finish the surface.
Function:
AE Corner beads can be used to alter the style of a building by making subtle design changes. Outer corner walls that have curved corners, as opposed to the traditional 90-degree straight angle, are called bullnose corners.
To achieve this look, affix a curved bullnose corner bead along the corner, where the two sheets of drywall come together and plaster mud is applied.
