22x22mm Profigips PVC Corner Bead for Arches - 3m length - pack of 50

22x22mm Profigips PVC Corner Bead for Arches is uniquely engineered with a hybrid wing design. While standard beads are rigid on both sides, this version features one continuous perforated wing and one segmented, notched wing. This allows the bead to be bent into a smooth, consistent radius without kinking or snapping. Trying to form a perfect curve by hand with render or plaster is incredibly difficult. The Profigips PVC Corner Bead for Arches is the professional solution to that problem, providing a rigid guide for one face and a snake-like flexibility for the other.

CHARACTERISTICS

• The rigid wing acts as a stable anchor against the flat wall surface, while the flexible, notched wing follows the contour of the arch or curve perfectly.
• Because the PVC nose is high-quality and flexible, it maintains a uniform edge around the entire curve. This eliminates the flat spots or jagged edges often seen with hand-formed arches.
• Just like its straight-edged siblings, this bead provides a tough PVC shield for the corner. This is vital for arched doorways and walkthroughs that are prone to being knocked by furniture or passing traffic.
• Arched features are often found in high-moisture areas like bespoke bathrooms or ornate external entrances. Being 100% PVC, this bead will never rust or cause unsightly tea-staining on the finish.
• It is suitable for a wide variety of radii, from tight decorative alcoves to large-span structural archways.

APPLICATION

• Arched Doorways: Creating a sharp, reinforced edge on curved internal or external walk-throughs.
• Curved Window Reveals: Perfect for traditional or bespoke architectural window designs.
• Decorative Alcoves: Used in high-end residential interiors to finish recessed shelving or feature walls with rounded headers.
• Curved Partition Walls: Essential for modern office or retail designs that feature winding or circular wall structures.

INSTALLATION

• Always fix the rigid wing to the flat wall surface first using staples or dabs of mortar. This provides the baseline for the arch.
• Gradually bend the segmented wing around the arch, fixing it as you go. For very tight curves, you may need to use more frequent fixings (such as stainless steel staples) to ensure the bead stays tight to the substrate.
• Ensure the plaster or render is pushed fully through the perforations on both the rigid and flexible wings. This creates the mechanical lock that prevents the bead from springing away from the curve over time.
• Use the PVC nose as a continuous guide for your trowel. The result will be a curve that looks like it was factory-moulded rather than hand-finished.
