What You'll Learn
Use spray adhesive
Using spray adhesive is a common method for attaching plastic corner beads. This method is effective, durable, and has been used for over 50 years.
To use spray adhesive, first, measure and cut the pieces to size using tin snips. Cut the ends of the pieces that meet on angles, and test to ensure they fit. Then, apply the spray adhesive to both sides of the corner, keeping the can at least 6 inches from the surface. Spray more adhesive on the inside of the corner bead. The Trim-Tex 847 spray adhesive is a high-tack, pressure-sensitive adhesive designed specifically for corner beads. It is a web spray, improving adhesion over standard mist sprays.
When using spray adhesive, it is essential to follow the manufacturer's instructions for drying time. After applying the adhesive, put pressure on both sides of the corner bead with a spackling knife where the bead meets the wall. Ensure that the bead is installed straight and attached firmly.
Spray adhesive can be used in conjunction with staples for added strength. The spray-and-staple technique involves spraying the adhesive and then stapling the bead in place. The adhesive minimizes slipping during expansion, while the staples provide additional security. However, some people choose to use staples alone, as they are concerned about the adhesive bleeding through and discolouring the mud and paint.

Staple them in place
Plastic corner beads are used on the edges of drywall construction walls to give a professional and finished look to corners. They can also be used between a ceiling and a wall and on a soffit. While spray adhesive is a common method to attach plastic corner beads, stapling them in place is another option.
Stapling is a good option if you want to avoid the use of adhesives. You can staple vinyl corner beads in place, but it is recommended that you use staples in conjunction with an adhesive for the best results. If you do opt for stapling without adhesive, you must ensure that the staples are spaced closely together, approximately 6 inches apart. However, stapling without adhesive can cause some sections of the edges between staples to bulge out, making it difficult to mud over.
If you are stapling and using adhesive, you will need to staple through the drywall into the stud behind, just as you would when nailing on a metal corner bead. The staples should provide enough holding power to secure the corner bead in place.
When installing plastic corner beads, it is important to apply light pressure on the bead toward the corner to ensure that the strip registers evenly along both walls and runs in a straight line. Misalignment can cause the bead to twist up the corner, and you will have to start again.

Choose the right material
Choosing the right material for your corner bead is crucial to ensure a secure and durable finish. While metal corner beads offer a crisp and sleek look, they are prone to denting and deformation, which can be challenging to repair. Metal beads are also more traditional and may be preferred for their classic aesthetic.
On the other hand, plastic corner beads, often made from vinyl, are known for their impact resistance and flexibility. Modern plastic technology has led to the development of high-performance vinyl materials that can withstand wear and tear. Vinyl beads are also available in various forms, such as abuse-resistant options for high-traffic areas and composite beads that conform to corners with angles other than 90 degrees.
Another advantage of vinyl corner beads is their ease of installation. They can be attached using spray adhesive, staples, or a combination of both. While some prefer spray adhesive for its convenience, others opt for staples to avoid the mess and potential health concerns associated with spraying indoors. However, vinyl beads installed solely with staples may require closer staple spacing and caution to prevent bulging or cracking.
For those seeking maximum durability, Mud Set Beads made from rigid vinyl offer an unbeatable bond. This innovative design features a series of hooks that grip into the joint compound, providing exceptional strength and impact resistance. The Mud Set method also saves time and labour by allowing for a quick fill coat application.
Ultimately, the choice between metal and plastic corner beads depends on the specific requirements of your project. Metal beads offer a timeless look, while plastic and vinyl beads provide durability, flexibility, and ease of installation. Consider the level of traffic and potential impact in your space, as well as your preferred installation method, to make an informed decision.

Use nails for a secure hold
Plastic corner beads are used on the edges of drywall construction walls to give a professional and finished look to corners. They can be made from a variety of materials, including plastic, metal, vinyl, paper, and composite materials.
One method of securing plastic corner beads is to use nails. While staples and screws are also an option, nails can provide a secure hold. If you plan to use nails, it is recommended to use ring shank drywall nails. This type of nail allows you to stop hammering before they are tapped too deeply, preventing puckering of the metal and avoiding issues when applying mud. Nails are also preferred by painters as they are easier to mud over.
To begin the process, cut the corner bead to length with tin snips, leaving about a half-inch gap at the bottom. Lightly press the corner bead into place, ensuring it is squared and aligned with the walls. Drive nails through the holes in the metal strip to secure its position. For added security, space nails about 8 inches apart along each leg of the corner bead.
It is important to note that misalignment can cause the bead to twist, requiring you to start over. Therefore, take care to apply light pressure when installing the corner bead and check that it is squared and straight before nailing it into place.

Apply joint compound
Applying joint compound is an essential step in securing plastic corner beads. Here's a detailed guide on how to do it effectively:
Prepare the Joint Compound:
Before you begin, ensure you have a sufficient amount of joint compound or "mud" ready. This compound will act as an adhesive and filling material to secure your plastic corner bead in place. It is recommended to use a compound specifically designed for drywall applications.
Apply the Compound to the Corner:
Using a knife or a compound applicator tube, apply the joint compound directly to the corner where the plastic corner bead will be installed. Spread the compound evenly, ensuring it covers the area where the bead will make contact. Avoid applying excessive pressure when spreading the compound, as this can result in an underfilled concave corner. The compound should be applied generously but smoothly.
Position the Plastic Corner Bead:
With the joint compound in place, it's time to position the plastic corner bead. Carefully align the bead with the corner, ensuring it is straight and level. Gently press the bead into the compound, applying pressure evenly. You can use a roller tool or the end of a taping knife to help with this process, ensuring the bead adheres firmly to the surface.
Smooth Out Excess Compound:
As you press the plastic corner bead into place, excess joint compound will likely be squeezed out through the perforations or mud holes in the bead. Use your taping knife to wipe down and smooth out this excess compound. This step is crucial for achieving a neat and professional finish.
Allow the Joint Compound to Dry:
Once you've positioned the plastic corner bead and smoothed out the excess compound, it's important to let the joint compound dry thoroughly. Follow the manufacturer's instructions for the recommended drying time. This step ensures that the compound sets properly, firmly securing the plastic corner bead in place.
By following these steps, you can effectively apply joint compound to secure your plastic corner bead, resulting in a strong and durable installation. Remember to work carefully and patiently, as rushing the process may affect the overall quality of your project.

Frequently asked questions
The standard way to attach plastic corner bead is with spray adhesive. You can also use contact cement, but this can be messier and fill up the mud lock holes.
You can use staples or screws to attach plastic corner bead. However, staples may not be as effective as they do not have much holding power and can cause bulging. Screws are more durable and sturdy, but the process is more involved.
For a quick installation, you can use the spray-and-staple method. This involves using spray adhesive and staples together.
For strong corners, the Mud Set method is the best. This involves applying mud to the corner with a roller tool or a knife and pressing the bead into place. The mud locks onto the surface through the bead's mud legs, creating a strong bond.
