Product Overview

The Simpson Strong Tie Plastic Bell Cast Bead is a premium-quality PVCu (unplasticised polyvinyl chloride) rendering accessory designed to create a drip detail at the base of external render systems. Measuring 3 metres in length, this bead is used to form a clean, defined lower edge to render finishes, ensuring proper water runoff and providing long-term protection to underlying building materials.

This bell cast bead is ideal for professional renderers, plasterers, and general contractors who require a neat and durable solution for finishing the bottom of rendered facades, plinths, or external wall terminations.

Boxed Weight

• Weight: 400g
  Lightweight and easy to handle on site or in storage, this bead simplifies logistics and installation for all users.

Key Features

• Durable PVCu Construction
  Manufactured from tough, weather-resistant unplasticised PVC, ensuring long-term durability and performance in all exterior conditions.

• Integrated Bell Cast (Drip) Profile
  Designed with a protruding lip to shed water away from the wall surface below, reducing staining, erosion, and moisture ingress.

• 3 Metre Length
  Supplied in a standard 3m length for efficient coverage of long wall runs with fewer joints.

• Provides Enhanced Weathering Protection
  Directs rainwater away from vulnerable wall areas and foundations, helping prevent damp-related problems and extending the life of render systems.

• Easy to Cut and Install
  The PVC material is simple to cut with standard tools such as tin snips or a fine-toothed saw, making it user-friendly for on-site adjustments.

• Safe and Clean to Work With
  Unlike metal beads, this PVC option is non-corrosive and has no sharp edges, improving safety for installers.

Applications

• External Rendering Projects
  Ideal for use at the base of rendered walls to create a drip detail and protect the structure below from water damage.

• New Builds and Renovations
  Equally suitable for new construction and refurbishment works where external render systems are being applied.

• Masonry, Blockwork, or Insulated Systems
  Compatible with a variety of external wall surfaces, including brick, block, and insulation-backed render systems.

Benefits

• Protects Against Water Penetration
  The bell cast profile ensures rainwater is directed away from the building’s surface, reducing the risk of dampness, frost damage, and staining.

• Improves Aesthetic Finish
  Provides a crisp, uniform base line to render finishes, enhancing the appearance of façades and improving visual consistency.

• Long-Term Durability
  Resistant to corrosion, cracking, UV degradation, and harsh weather conditions, this PVCu bead maintains its shape and function over time.

• Minimises Maintenance
  By reducing water runoff down the wall, this bead helps maintain the appearance and structural integrity of rendered façades.

• Lightweight and Cost-Effective
  Easy to transport and install, with minimal waste or installation time—making it both practical and economical for small or large-scale projects.

Installation Instructions

1. Measure and Cut
   Cut the bead to the required length using snips or a fine-toothed saw.

2. Fix in Place
   Attach the bead to the base of the wall using mechanical fixings, render adhesive, or embed it in the base coat of the render.

3. Align the Drip Edge
   Ensure the bell cast lip is level and projects outwards to allow water to drip clear of the wall.

4. Render Over
   Apply the render up to the top edge of the bead, allowing the bead’s profile to create a clean break at the base.

Compliance and Suitability

• Manufactured to meet standard UK construction and rendering practices.

• Suitable for use with a wide range of rendering materials including traditional sand/cement, monocouche, and polymer-modified renders.

Frequently Asked Questions (FAQ)

Q1: What is the purpose of a bell cast bead?
A1: A bell cast bead forms a drip edge at the bottom of a rendered wall, directing water away from the surface below. This helps prevent damp, staining, and erosion of the wall base or plinth.

Q2: Is this bead suitable for internal use?
A2: No. Bell cast beads are specifically designed for external rendering applications. For internal plastering, a stop bead or angle bead is more appropriate.

Q3: Can this bead be painted?
A3: Yes. Once the render is applied and dried, the entire surface—including the visible part of the bead—can be painted using standard exterior-grade paints.

Q4: How do I cut the bead to size?
A4: The PVCu construction makes it easy to cut with hand tools such as tin snips or a fine-toothed hacksaw. Always wear safety gear when cutting.

Q5: Is the bead UV-resistant?
A5: Yes. The high-quality PVCu material is UV-stabilised to resist degradation and discoloration from prolonged sun exposure.

Q6: What thickness of render is this compatible with?
A6: The bell cast profile is generally suited for use with render applications ranging from 10mm to 15mm in thickness. Always verify render compatibility before use.

Summary

The Simpson Strong Tie Plastic Bell Cast Bead 3m is an essential finishing component for external render applications, combining functionality, weather protection, and ease of installation. Its robust PVCu construction, integrated drip profile, and user-friendly design make it the go-to solution for professionals seeking long-lasting, aesthetically pleasing render terminations.
