Render Bead
Render beads are the finishing touch that gives external walls a sharp, well-defined edge. They add structure and longevity to rendered surfaces. Builders use them to achieve precise lines while reducing cracking and moisture penetration around corners and joints.
What is render beads?
Render beads, or bead for render, can be made from either metal or PVC. They come in many shapes and are designed to be set underneath or embedded in the render layer.
Their purpose is to shape and secure edges, corners, and terminations. These beads act as a guide during application, helping renderers achieve a level surface and a uniform finish with lasting stability.
What is render bead used for?
Render beads are installed wherever render meets an edge, corner, or joint in external and internal render or plaster systems. The right bead improves appearance and long-term performance.
They are used to:
- Strengthen vulnerable areas such as wall corners and window reveals.
- Create sharp, even edges for a trade-quality finish.
- Control render thickness for uniform coverage.
- Protect edges from impact, stress, and damp penetration.
- Help channel water away from façades when using render bellcast beads.
Types of rendering beads
Every rendering bead profile is designed for a specific edge, joint, or finish type:
- Render Stop Bead – Available in Plastic and Stainless Steel. Provides a neat termination point where the render ends, preventing cracks at joints or abutments.
- Render Bellcast Bead – Available in Plastic. Sheds rain effectively, reducing staining and moisture tracking to protect the wall beneath.
- Drip Bead – Available in Plastic. Deflects rainfall away from the wall base or openings for better water management.
- Render Angle Bead – Available in Plastic and Stainless Steel. Strengthens corners and ensures straight lines.
- Movement (Expansion) Bead – Available in Plastic. Absorbs heat movement and reduces strain across the surface.
