They are dent-resistant and do not rust or corrode, ensuring a long-lasting and clean finish. Moreover, vinyl corner beads can be easily cut to the desired length, making installation a breeze. Their flexibility also enables seamless adjustments along corners, resulting in a perfect fit.
Overall, vinyl corner beads provide superior durability and appearance, making them a reliable choice for drywall installations.
Advantages And Disadvantages Of Paper-Faced Corner Beads
Paper-faced corner beads have gained popularity in recent years due to their ability to eliminate cracking and nail popping, common issues associated with traditional metal corner beads. The paper facing of these corner beads provides a smooth, jointless finish, resulting in aesthetically pleasing corners.
One of the significant advantages of paper-faced corner beads is their ability to blend seamlessly with the surrounding drywall. The paper surface can be easily painted over, creating a uniform appearance without the need for additional finishing materials. However, it is essential to exercise caution during installation, as improper techniques can lead to peeling and detachment of the paper facing. Careful application and following manufacturer guidelines can prevent these issues and ensure a successful installation.
Types Of Drywall Corner Beads: Soft Profile Vs. Sharp Profile
When selecting a corner bead, it is important to consider the desired visual appearance. Two popular options are soft profile corner beads and sharp profile corner beads, each offering a distinct look and function.
Soft profile corner beads have a slightly rounded corner, contributing to a smooth and visually appealing finish. They are often chosen for areas where a softer, more subtle appearance is desired, such as in residential settings or rooms with a more relaxed aesthetic.
On the other hand, sharp profile corner beads create a sharp outside corner, reducing the need for additional finishing material, such as joint compound or plaster. These corner beads are frequently used in commercial spaces or areas that require a crisper and more defined edge, emphasizing a modern and sleek style.
Corner beads are essential components in drywall installations, providing the finishing touches to outside corners. They are available in various materials such as metal, vinyl, and paper-faced, each with its own set of advantages and considerations. Choosing the appropriate corner bead for your specific needs is crucial to achieve a professional, long-lasting, and aesthetically pleasing result.

Frequently Asked Questions
What is the purpose of corner bead?
The purpose of corner bead is to ensure a smooth and professional finish at the outside corners where two materials meet. By using corner bead, the need for repeatedly cutting and filling the gap between the materials is eliminated, resulting in a seamless join. Additionally, corner beads enhance the durability of drywall, adding an extra layer of protection to the corners and preventing them from getting damaged over time.
Do I need corner bead for drywall?
Yes, it is essential to use corner bead for drywall installations. The purpose of corner bead is to reinforce the joints where two pieces of drywall meet at a 90-degree angle, preventing them from cracking or chipping. By adding strength and rigidity, corner bead ensures a more durable and long-lasting drywall surface, increasing its resistance to potential damage and enhancing the overall quality of the installation.
What is the difference between angle beads and corner beads?
Angle beads and corner beads serve similar purposes in reinforcing the corners and returns of external rendered elevations and apertures. However, the main difference lies in their design and application. Angle beads, also referred to as quoin beads, are specifically used on corners and returns. They provide additional strength to the render system, protecting it from impact damage and maintaining sharp edges. On the other hand, corner beads, as the name suggests, are primarily used on corners. They also reinforce the render system at corners, but they may not be suitable for returns as they are specifically designed for corners.
How do you attach corner bead to drywall?
To attach corner bead to drywall, start by applying a thin layer of adhesive to both the corner bead and the drywall surface. Allow the adhesive to become tacky for a minute before carefully placing the bead onto the corner. Apply firm pressure to ensure proper adhesion, and then secure the bead to the wall using half-inch staples placed every six to eight inches. This method ensures a secure attachment of the corner bead to the drywall, resulting in a professional finish.
