Render Stop Beads

Render stop beads are used to create a clean, defined edge where render finishes start or stop. They provide a precise termination point around windows, doors, base details, and junctions with other materials, while also protecting the edge of the render from cracking, chipping, and weather-related damage.

Commonly used in external rendering and plastering systems, render stop beads help achieve a professional finish by guiding the render to a straight, consistent edge. They reduce the need for trimming or corrective work once the render has cured and improve overall accuracy during installation.

Where Render Stop Beads Are Used

Render stop beads are typically installed:

• Around window and door openings
• At the base of rendered walls
• Where render meets frames, trims, or different finishes
• At changes in material or surface type
• To create neat edges on external façades and elevations

They are suitable for use with a wide range of render systems, including traditional sand and cement render, thin coat render systems, and selected internal plaster applications.

Materials and Finish Options

Render stop beads are available in several materials to suit different environments:

• Galvanised steel – Suitable for sheltered external areas and internal render applications where moisture exposure is limited.
• Stainless steel – Recommended for exposed locations, coastal areas, or environments subject to persistent damp or extended drying times.
• uPVC – Lightweight and corrosion-resistant, ideal for external use and areas exposed to moisture or temperature changes.

Selecting the correct material is essential to prevent corrosion, staining, and premature failure of the render finish.

Benefits of Using Render Stop Beads

• Creates clean, straight termination lines
• Protects vulnerable render edges from damage
• Improves accuracy and consistency during rendering
• Reduces cracking and edge failure
• Helps achieve a long-lasting, professional finish

Installation and Safe Use

Render stop beads should be fixed securely and aligned accurately before rendering begins. Always ensure the bead material is compatible with the environment and fixing method used. When cutting or handling beads, wear appropriate gloves, as edges may be sharp.

Correct installation and material selection play a key role in the durability and appearance of the finished render.

Pack Sizes

Render stop beads in this range are supplied in bulk packs, making them suitable for site use and larger projects.

Galvanised and stainless steel render stop beads are supplied in boxes of 50, while uPVC render stop beads are supplied in boxes of 25.
