How do you use PVC corner beads?

For over half a century, Trim-Tex's vinyl corner beads were synonymous with a single installation method: spray adhesive and staples. Today, the range of installation techniques has expanded. Whether you seek a fast installation or the strongest corners, there is a method to suit your needs.

Three primary methods to consider for corner bead installation include: traditional spray-and-staple, Mud Set, and Fast Edge®. Each approach is unique, so review product instructions carefully before starting the installation.

Once the drywall is affixed, external corners, uncased openings, beams, and soffits should be reinforced using corner bead. This not only resists impact but also provides a crisp edge for taping. Ideally, corner beads should be installed in a single piece. For vertical applications, cut the bead 1/2 inch shorter than the ceiling height, pushing it tight against the ceiling. This allows the baseboard to cover any floor gap, minimizing potential issues from wall settling. If multiple pieces are necessary, ensure they butt together without overlapping, aligned evenly.

There are various corner and trim beads available. Here’s a brief guide on their attachment methods:

Metal Beads

When attaching to drywall over wood framing, galvanized metal bead is usually nailed. For metal framing, use a corner crimper and 9/16-in. staples that penetrate both drywall and framing. Attach the bead every 8 inches with pairs of fasteners on either side of the corner. Some metal beads have barbed edges that secure the bead with minimal fasteners, requiring hand pressure or a rubber mallet for proper alignment.

WORK SMART: Ensure the corner bead edges lay flat against the wall; they shouldn’t protrude past the raised edge of the corner.

PVC Beads

PVC corner bead offers durability and ease of installation. Joint compound is typically used to secure the bead. A specialized tool can apply the compound to the bead’s back, which is then pressed into place with a roller tool. Suitable for drywall over both wood and metal framing, these beads help reduce corner cracking more effectively than standard metal beads.

Vinyl Beads

There are various vinyl bead types on the market, and they can be installed using three methods. First, measure and dry-fit the bead. Then, choose one of the following options: Install with 1/2-in. staples every 6-10 inches, use vinyl adhesive on both drywall and bead, or use joint compound, pressing the bead until the compound oozes through the holes before smoothing with a taping knife.

Attaching Vinyl Beads

Vinyl bead outlasts metal bead, especially when combined with adhesive and staples.

Paper-faced Beads

Paper-faced metal and plastic beads are installed with joint compound, typically after seams have been taped and a first layer of compound applied. This compound fills gaps and provides a level surface for the bead. Use a taping knife or corner roller to embed the bead, ensuring the paper flanges lie flat against the wall.

Shaped Beads and Accessories

Bullnose corner beads have gained popularity for their refined look. Available in sizes from 3/8 to 1-1/2 inches, they come with various accessories for smooth transitions at curves and corners. For a straight-line style with a touch of flair, the chamfer-style bead is an excellent option.

WORK SMART: If using larger bullnose beads, cut the drywall short to fit the bead’s curve.
