There are several methods to attach a corner drywall plastic bead. One standard method is to use a spray adhesive, such as Trim-Tex 847, and then staple the bead in place. Another method is to use a mud set, which involves applying mud to the corner and pressing the bead into place. This creates a strong bond between the bead and the drywall. A third method is to use nails and screws, although this can be less secure.

What You'll Learn
Using spray adhesive
The process involves applying the adhesive to both the drywall and the bead. Spray continuously from a distance of 6 to 10 inches, ensuring that the spray is constantly moving to avoid excessive buildup on the surfaces. The Trim-Tex 847 Spray Adhesive is a recommended product for this purpose, as it is designed specifically for corner beads, improving adhesion compared to standard mist sprays.
After spraying, position the bead into place, pressing it firmly against the drywall. A pressuring tool or the handle of a taping knife can be used for this step. It is important to ensure that the bead is installed straight and securely attached to the drywall, with both sides of the bead lying flat against the surface.
Once the bead is in place, you can further reinforce the bond by stapling along the mud leg every 6 to 8 inches. This additional step provides a strong and lasting hold. Allow the adhesive to dry according to the manufacturer's instructions before proceeding with any further steps, such as spackling or mudding.
While spray adhesive is a popular choice, there are some considerations to keep in mind. One concern is the potential for adhesive bleeding through and discolouring the mud and paint. Additionally, the use of spray adhesive may be messy and can result in adhesive ending up on unintended surfaces. It is also important to work carefully and avoid creating kinks or openings between the bead and the drywall during installation.

Stapling
To begin, measure and cut the pieces of the plastic corner bead using a pair of tin snips. Cut the ends of the pieces that meet on angles and test to ensure they fit together. Next, apply a spray adhesive to both sides of the corner and the inside of the corner bead. The Trim-Tex 847 spray adhesive is a popular choice for this purpose. Spray continuously from a distance of 6 to 10 inches, keeping the spray moving to avoid buildup.
Once the adhesive is applied, position the bead into place, pressing it firmly with a pressure tool or the handle of a taping knife. Finally, staple the bead every 6 to 8 inches using a stapler such as the Trim-Tex 1/2" divergent pneumatic stapler or the T50 stapler with 3/8" staples.
It is important to note that stapling is often used in conjunction with spray adhesive for a stronger bond. The spray adhesive helps to minimize slipping during expansion, while the staples provide additional security. This combination is a standard method used by professionals and has proven to be effective and long-lasting.

Mud set beads
To install, begin by applying the mud directly to the corner. Then, press the bead into place using a roller tool or the end of a taping knife. The excess mud will squeeze through the perforations, levelling out the bead and reducing the amount of mud needed for the setting coat. This process also helps create an incredibly strong bond between the bead and the drywall.
When compared to traditional corner beads, Mud Set Beads offer superior durability and impact resistance. While traditional metal corner beads can be easily dented and deformed, requiring replacement, Mud Set Beads can withstand impacts without any damage to their nose. In the rare case of any damage, it is usually the drywall mud that fails, which can be easily patched up without needing to replace the entire bead.

Nailing
Prepare the Corner Bead:
Before beginning the installation, it is essential to prepare the corner bead by cutting it to the appropriate length. Use tin snips or a similar tool to cut the corner bead, ensuring that the bottom end is about half an inch off the floor. This will allow the baseboard molding to conceal any gaps at the bottom.
Mark the Position:
Lightly press the corner bead into the corner, squaring the legs of the strip against the walls. This will give you an idea of where to place the nails for a secure hold. You can also use a drywall corner bead clincher to help you position the metal strip accurately and quickly.
Nail the Corner Bead:
Drive nails through the holes in the metal strip to establish its position. For added strength, you can drive three nails through each leg of the corner bead, spacing them about 8 inches apart. Make sure the nails are firmly seated and do not twist or press the bead too tightly as you work. Additionally, consider using drywall nails, which allow you to stop hammering before they puckering the metal, providing a smoother finish for mudding.
Finish with Mud:
Once the corner bead is securely nailed in place, you can finish the installation by applying mud or joint compound. Use a drywall knife to apply a thin coat of mud along the corner, filling the tapered seam first to create a continuous bearing surface. This will enhance the bond between the bead and the drywall, creating a seamless corner.
While nailing is a common method for attaching corner drywall plastic beads, it is important to note that there are alternative methods, such as using adhesive or staples, which can also provide a strong and secure hold.

Screws
Using screws to attach a plastic corner bead to drywall is a common method, especially when compared to vinyl corner beads, which are usually installed with spray adhesive.
To start, you must find the wood stud in the corner of the room and measure its height from top to bottom with a tape measure. Then, cut your corner bead to the appropriate length, keeping the bottom end about 1/2 inch off the floor.
Next, take a drywall screw and line it up at the top of the bead. Drill it into the wall stud through the hole in the bead until it is flush with the bead. Repeat this process on the other side of the bead, putting a screw on each side until you reach the bottom. Make sure that the bead is secure and straight before proceeding.
After securing the corner bead with screws, you can cover it with a joint compound. Spread the compound evenly until you can no longer see the corner bead. Finally, sand down the area with medium-grade sandpaper, smoothing it out with a circular, even motion.
While screws are a common method for attaching plastic corner beads, some people may prefer to use drywall nails or staples for added security. Additionally, when working with wood studs, nails or staples are often easier to work with than screws.

Frequently asked questions
There are several ways to attach a corner drywall plastic bead. The standard way is to use spray adhesive, and then staple the bead in place. Another way is to use a product like Trim-Tex's Mud Set Beads, which does not require glue or staples. A third option is to nail the bead to the studs through the drywall and finish with a compound.
First, apply the spray adhesive to the drywall and the bead. Hold the spray can 6 to 10 inches away from the surface and keep it moving to avoid buildup. Then, position the bead and press it into place with a pressure tool or taping knife handle. Finally, staple the bead every 6 to 8 inches.
Mud Set Beads are made from high-impact, rigid vinyl and feature Trim-Tex's patented Mud Lock Technology. This technology uses a series of hooks along the bead's mud legs that grip into the joint compound, creating an incredibly strong bond between the bead and the drywall. This bond can withstand a high degree of impact, reducing maintenance costs and the need for replacements.
