Movement Beads

Movement beads are designed to accommodate expansion and contraction within plaster and render systems, helping to reduce cracking and maintain a clean finish. They are commonly used where movement is expected across larger surfaces or between different substrates.

Movement Beads at a Glance

What are movement beads used for?

Where should movement beads be used?

Movement beads are installed in areas where surfaces are likely to move or where stress could cause cracking in the finish.

• Long or uninterrupted wall runs
• Junctions between different substrates
• Areas subject to thermal or structural movement
• Changes in render or plaster finish

Can movement beads be used as stop beads?

Yes, movement beads can also act as stop beads where a clean edge or defined break in the finish is required. This makes them a flexible option for both movement control and finishing details.

Choosing the right material

Galvanised movement beads are suitable for internal plastering applications and provide a strong, reliable solution for standard environments.

Stainless steel movement beads are ideal for external or exposed conditions where corrosion resistance is required.

uPVC movement beads offer a flexible, non-metal option that performs well in both internal and external environments, particularly where moisture is present.

Choosing the right size

The size of the movement bead should match the depth of the plaster or render system. Using the correct size ensures proper performance and a consistent finish.

• 10mm–12mm – suitable for thinner plaster applications
• 15mm–16mm – standard render and plaster depths
• 20mm – heavier render builds and larger movement areas

Supplied for trade and site use

Movement beads are supplied in trade pack quantities to suit larger jobs and repeat use. Galvanised and stainless steel options are supplied in boxes of 50, while uPVC beads are supplied in boxes of 25.
