Angle Bead vs Stop Bead: What’s the Difference & When to Use Each

Angle beads and stop beads are both essential for plastering, but they serve very different purposes on site.

Using the correct bead helps you achieve a cleaner finish, stronger edges and a more professional result.

What Is the Difference Between Angle Bead and Stop Bead?

Angle beads are used to form and protect external corners, while stop beads create a clean edge where plaster finishes.

In simple terms:

  • Angle bead = strengthens and protects corners
  • Stop bead = creates a neat stopping point

What Is an Angle Bead?

Angle beads (corner beads) are used to form straight, durable external corners.

  • Installed on external corners before plastering
  • Protects edges from impact and damage
  • Creates sharp, consistent lines

They are commonly used on wall corners, window reveals and high-traffic areas.

Angle beads are available in galvanised steel, stainless steel and plastic options depending on the environment.

What Is a Stop Bead?

Stop beads are used to create a clean, straight edge where plaster finishes.

  • Prevents plaster from spreading too far
  • Creates a neat finish line
  • Improves overall appearance

They are typically used around windows, doors and where plaster meets another surface.

Stop beads are available for both internal plastering and external rendering applications.
