Render Stop Beads

Render stop beads are used to create a clean finish at the base of rendered walls while allowing water to run off effectively. They form a defined drip edge that helps prevent staining and protects the render from moisture damage.

Render Stop Beads at a Glance

What are render stop beads used for?

Where should render stop beads be used?

Render stop beads are typically installed at the base of external walls to manage water run-off and create a defined edge.

• Base of rendered walls
• External rendering systems
• Areas exposed to weather or moisture
• Where a clean render termination is required

Why are drip edges important?

The drip edge created by a render stop bead helps direct water away from the wall surface. Without it, water can run back onto the render, leading to staining, damp issues, and premature failure.

• Prevents water tracking back onto the wall
• Reduces staining and discolouration
• Improves long-term performance of render systems

Choosing the right material

Galvanised render stop beads are suitable for sheltered external environments and general rendering work.

Stainless steel render stop beads are designed for exposed or coastal environments where corrosion resistance is essential.

uPVC render stop beads provide a durable, non-metal option and are ideal for external render systems, particularly where moisture exposure is high.

Choosing the right size

The depth of the bead should match the thickness of the render system to ensure a clean finish and proper water run-off.

• 6–12mm – for thinner render systems
• 10–15mm – standard render applications
• 12–22mm – thicker render builds

Supplied for trade and site use

Render stop beads are supplied in trade pack quantities to suit larger projects and consistent installation. Steel options are supplied in boxes of 50, while uPVC beads are supplied in boxes of 25.
