Drywall Corner Bead Types and Installation Techniques
A plasterboard corner bead is a protective strip that is installed on the exposed edge of plasterboard at corners of walls and ceilings. The primary function of a corner bead is to provide rigidity and support, preventing corner damage or denting. Additionally, corner beads create a smooth, even surface for joint compound application, ensuring a professional appearance and seamless transitions between adjacent drywall surfaces.
Introduction to Drywall Corner Beads
Drywall corner beads are an important element in achieving a professional finish on interior walls and ceilings. It provides strength and protection to drywall corners, ensuring they stay crisp, clean and straight. This comprehensive guide will cover the different types of drywall corner bead available, the corner bead tools needed for a perfect installation, and detailed instructions on how to install them for a perfect finish.
Different Types of Drywall Corner Beads
paper corner bead
Paper corner beads are made of a metal or plastic core covered with a layer of paper. This type of bead is popular for its smooth finish, which blends seamlessly with drywall surfaces. The paper side also forms a good bond with the joint compound, ensuring corners are strong and durable.
metal corner beads
Metal corner beads are the traditional choice for securing drywall corners. Made of galvanized steel or aluminum, this bead offers a high level of durability and strength. Its sturdy design makes it ideal for right angles and is less prone to dents and cracks. However, working with metal corner beads can be more challenging, as they may require additional fasteners and careful handling to avoid sharp edges.
vinyl corner beads
Vinyl corner beads are a flexible and lightweight option that are easy to install. Anti-rust and moisture-proof, suitable for high-humidity environments such as bathrooms and kitchens. Vinyl corner guards are also less likely to crack or dent than metal corner guards, but it may not offer the same level of stiffness and strength.
Ox nose horn beads
Bullnose Corner Beads are designed to create rounded, smooth transitions between adjacent drywall surfaces. This type of bead is popular for its elegant, modern aesthetic and ability to soften the appearance of sharp corners. Bull nose horn beads are available in metal, vinyl, and paper varieties.
How to Install Drywall Corner Beads
1. Measure and cut the corner bead: First measure the length of the corner where the bead will be installed. Cut the corner bead to length using a utility knife, tin snips, or a fine-tooth saw.
2. Position the corner bead: Hold the corner bead against the drywall corner making sure it is aligned and level. Press the bead firmly against the wall, making sure it fits evenly along the entire length of the corner.
3. Fixing the corner beads: For metal corner beads, use the corner bead clamp to position the metal strip correctly and fix it quickly. Every time you hit the riveting tool, it cuts the metal prongs and presses them into the drywall. For added security, drive three nails into each leg of the corner bead to create a mechanical connection to the frame. For vinyl and paper corner beads, use drywall screws or nails to secure the corner beads to the wall at approximately 8 to 12 inch intervals. Make sure the fastener is straight and flush with the bead surface.
4. Apply joint compound: Once the corner bead is firmly in place, apply a coat of joint compound to the bead, extending about 2 to 3 inches on either side of the corner. Use a tape knife to smooth the compound, feathering the edges for a seamless transition.
5. Allow to dry and sand: Allow the joint compound to dry completely following the manufacturer's instructions. Once dry, use sandpaper or a sanding sponge to buff away any rough areas or imperfections.
6. Apply additional coats as needed: For a professional finish, apply additional coats of joint compound, allowing each coat to dry and sanding between applications. Be sure to feather the edges of each layer for a seamless look.
7. Primer and paint: Once the final coat of joint compound is dry and sanded, apply a coat of primer to the corner bead and surrounding drywall. Allow the primer to dry, then paint the walls as desired.
