Bellcast Beads

Professional bellcast beads and drip beads designed for clean, controlled water run-off on external render systems. Our range includes durable PVC bellcast beads and metal options, providing a strong, straight edge and long-lasting protection for rendered walls, windows and base details.

What are bellcast beads?

Bellcast beads, also known as drip beads, are specialised render beads installed on horizontal terminations of render. They are designed to create a clean edge and form a drip, helping shed rainwater away from the wall and preventing streaking or water damage.

Their role in external render systems

Within an external render system, bellcast beads form a controlled break line at the base of render zones or above windows. By directing rain water away from the wall surface, they protect the façade from long-term moisture exposure and staining.

Purpose and benefits of using bellcast render beads

• Helps cut water run-off and prevent unsightly staining.
• Creates a clean straight edge finish on rendered walls.
• Designed to shed rainwater away from the building.
• Reduces surface damage caused by continuous water exposure.
• Enhances durability of the render base and lower wall section.

Preventing water runoff with drip beads

Drip beads work by projecting slightly from the surface, allowing rainwater to break away from the wall rather than tracking back underneath. This protects weaker areas around openings, exposed edges and lower wall sections.

Types of render beads

We supply a variety of render bead types and materials to suit different project requirements and budgets.

Plastic, stainless steel, and aluminium options

• PVC bellcast beads – lightweight, corrosion-resistant and easy to install. Available in clean white finishes.
• Stainless steel beads – high durability and ideal for exposed or coastal applications.
• Aluminium beads – strong yet lightweight for professional external finishes.

All options are available in multiple sizes and length options, measured in mm, to suit different render thicknesses.

How to use a bellcast bead

Bellcast beads are fitted horizontally at render terminations or transitions. They must be aligned carefully to maintain a consistent straight edge and effective water drip.

Fixing methods and suitable adhesives

• Place into fresh render or basecoat using strong adhesive materials.
• Attach to metal lath systems using fixings if required.
• Cut beads to size using tin snips for metal or shears for PVC.
• Ensure alignment before final application to guarantee a clean finish.

All beads are suitable for professional installers and DIY users, offering an easy fixing process and consistent results.
