Installing plastic sheet rock beads, also known as drywall corner beads, is a simple process that can greatly improve the look of your drywall. Corner beads are protective strips that cover the exposed edges of drywall where two pieces meet at a corner, creating a smooth, even seam and an attractive finish. There are several types of corner beads available, including metal, paper-faced, and plastic or vinyl beads, each with its own advantages and installation methods. Plastic corner beads, in particular, offer flexibility, lightweight durability, and resistance to rust and moisture, making them ideal for high-humidity environments. With the right tools and preparation, you can achieve a professional and seamless finish for your interior walls and ceilings.

What You'll Learn
Choosing the right material
Plastic sheet rock beads, also known as corner beads, are available in a variety of materials, including metal, vinyl, and paper-faced beads. Each type of material has its own unique characteristics and advantages. Here are some factors to consider when choosing the right material for your project:
- Metal Beads: Metal corner beads, made of galvanized steel or aluminium, offer high durability and strength. They are resistant to denting and cracking and are ideal for creating straight corners. Metal beads are traditionally used and are relatively easy to install, requiring screws or nails for installation. However, they are more prone to rust and corrosion in damp locations and can be challenging to work with due to the need for careful handling and additional fasteners.
- Vinyl Beads: Vinyl corner beads are known for their durability and flexibility. They are resistant to rust and moisture, making them suitable for high-humidity environments. Vinyl beads are less likely to dent compared to metal beads and are easier to maintain, as they can be mudded instead of replaced in case of damage. They may require adhesives for installation. Vinyl beads are often made from recycled plastics, making them a more environmentally friendly option.
- Paper-faced Beads: Paper-faced beads have a metal or plastic core coated with a layer of paper. They are popular due to their smooth finish, which seamlessly blends with drywall surfaces. Paper-faced beads create a strong bond with joint compounds, resulting in durable corners. However, they may require additional staples for security, and improper installation can lead to peeling, requiring re-installation.
- Bullnose Beads: Bullnose corner beads are available in metal, vinyl, and paper-faced varieties. They create a rounded, smooth transition between adjacent drywall surfaces, adding style and a contemporary aesthetic. Bullnose beads can be simply nailed into place, but they may require additional carpentry skills and fabrication for certain installations.
When choosing the right material for plastic sheet rock beads, consider factors such as durability, ease of installation, resistance to damage and corrosion, environmental conditions, and the desired aesthetic for your project. Additionally, think about your level of DIY skills and comfort with the required tools for each material.

Prep work
Before installing plastic sheet rock beads, there are several preparation steps to complete. First, measure the drywall from floor to ceiling, or from the moulding to the ceiling if your drywall does not reach the ceiling. For both types of drywall beads, leave a small space at each end, around half an inch.
Next, cut the corner bead to length, keeping the bottom end around half an inch off the floor. This gap will be concealed by the baseboard. If more than one piece is required, butt the beads together rather than overlapping them, ensuring that the ends are even and straight.
Before attaching the beads, ensure that any sharp edges on the drywall have been cut or sanded down. Double-check that the drywall is clean and ready to apply primer everywhere but the corner.
The next steps depend on the type of bead you are using. For paper-faced beads, cut the paper to size. For metal beads, you will need to use aviation snips to cut the bead to size. For vinyl corner beads, you can use standard vinyl, Mud Set or Fast Edge® methods. For the traditional vinyl corner bead installation, you will need to use spray adhesive and staples. For the Mud Set method, you will need to apply mud to the corner before pressing the bead into place.

Cutting the plastic sheet rock bead
First, measure the drywall from floor to ceiling, or from the moulding to the ceiling if your drywall doesn't reach the ceiling height. It is important to leave a small gap of about half an inch at each end of the drywall. This gap is crucial to prevent any potential issues that may arise if the building settles or moves.
When cutting the plastic sheet rock bead, use tin snips or aviation snips to cut it to the desired length. Ensure that the bottom end of the bead is about half an inch off the floor. The baseboard will conceal any gap left at the end, so it is important not to cut it too short. Additionally, if you are installing the bead on a wall that reaches the ceiling, cut the bead to be about half an inch short of the ceiling height. This will ensure a tight fit against the ceiling, while also allowing for any potential movement or settling of the building.
It is important to note that cutting plastic sheet rock beads is much easier than cutting drywall. When cutting the bead, focus on achieving straight and clean edges. Avoid any sharp or rounded edges, as this can affect the overall fit and finish of the installation. Take your time and cut slowly and carefully to ensure accuracy.
After cutting the plastic sheet rock bead to the correct length, it is now ready to be installed. Remember to handle the bead with care, as the edges may be sharp after cutting. With the proper measurements and cutting technique, you will achieve a seamless and professional finish for your drywall installation.

Attaching the plastic sheet rock bead
The method of attachment will depend on the type of corner bead you are using. Paper-faced beads are attached by applying a thin layer of joint compound along the corner and then pressing the beads into the compound. Metal beads are applied in a similar way, with a thin layer of compound, but are then secured with small nails or a corner crimper. Nails should be spaced around 8 inches apart.
Vinyl corner beads can be attached in a few different ways. One way is to use spray adhesive and staples. Another method is to use a compound applicator tube to apply mud to the corner and then press the bead into place with a roller tool. A third option is to use a 4-in-1 Mud Hopper to apply the mud and then press the bead into place.
Bullnose beads are another type of corner bead that may require a different installation method. These are nailed into place, with fasteners spaced around 8 inches apart.
It is important to apply light pressure to the bead during installation to ensure it registers evenly along both walls and runs in a straight line.

Finishing touches
When installing plastic sheet rock beads, there are several methods and tools you can use to achieve a seamless, professional finish. The first step is to cut the corner bead to length, ensuring that it is about half an inch off the floor. This will allow for any baseboard moulding to conceal the gap at the bottom.
Next, apply light pressure to the corner of the bead, ensuring that the legs are squared against the walls. You can then use a drywall corner bead roller, a taping knife, or a putty scraper to apply a thin layer of joint compound or mud over the bead and the corner. This compound will help fill any gaps and create a smooth, even surface for your plastic sheet rock bead.
For added security, you can also use nails or staples to fasten the bead in place. Space these fasteners about 8 inches apart along each leg of the bead. If you choose to use nails, be sure to use small nails and a hammer to avoid creating depressions in the bead.
Finally, once the compound has dried, you can sand it down to create a flawless, smooth finish. This finishing step will ensure that your plastic sheet rock bead is securely in place and will provide a seamless transition between adjacent drywall surfaces.
