Plaster Stop Beads

Plaster stop beads are used to create clean, defined plaster edges where plaster finishes against adjoining materials. They help form a neat termination point on reveals, frames and exposed edges while improving consistency across plastering and dry lining work.

Plaster Stop Beads at a Glance

What are plaster stop beads used for?

Where should plasterboard stop beads be used?

Plaster stop beads are commonly used where plaster needs to stop neatly against another surface, rather than continuing around a corner or edge.

• Door and window reveals
• Plaster terminations against other materials
• Internal plastered walls and ceilings
• Damp or exposed applications where a suitable stop bead material and plastering system are specified

Thin coat vs standard plaster stop beads

Thin coat plaster stop beads are designed for skim and thin-coat plaster systems, typically around 3mm. They are ideal where a low-profile finish is needed on plasterboard or aerated blockwork.

Standard plaster stop beads are used for thicker plaster builds where a deeper stop bead is required to match the finish depth.

Choosing the right material

Galvanised plaster stop beads are a reliable choice for internal plastering in dry conditions. They provide a strong, straight edge for standard site work.

Stainless steel plaster stop beads are best suited to external use, rendering, or internal areas exposed to moisture or condensation.

uPVC plaster stop beads offer a non-metal option for damp-prone or external environments and are available in a wide range of depth bands to suit different plaster builds.

Choosing the right size plaster stop bead

The bead depth should suit the thickness of the plaster system and the finished detail required. Selecting the correct profile helps create a clean termination and consistent finished edge.

3mm thin coat stop beads are designed for skim and thin-coat plaster systems, while deeper stop bead profiles are available for applications requiring a greater finish depth.

Always check the individual product specifications and installation guidance when selecting the correct profile.

Supplied for trade and site use

Our plaster stop beads are supplied in trade pack quantities to suit regular site use and larger jobs. Galvanised and stainless steel options are supplied in boxes of 50, while uPVC stop beads are supplied in boxes of 25.

• Edge Beads – for protecting exposed plasterboard edges and creating clean finishing lines.
• Movement Beads – for accommodating movement within plaster and render systems and helping reduce the risk of cracking.

Plaster Stop Beads FAQs

What is a plaster stop bead used for?
A plaster stop bead is used to create a clean termination where plaster finishes against another surface, such as a frame, reveal or adjoining material.

What is the difference between a stop bead and a corner bead?
A stop bead creates a defined termination where the plaster finish ends, while a corner bead protects and reinforces an external corner.

What is the difference between a stop bead and an edge bead?
A plaster stop bead creates a defined point where the plaster finish terminates. An edge bead is used to protect and finish an exposed plasterboard edge. The correct profile depends on the construction and finished detail required.

When should I use stainless steel plaster stop beads?
Stainless steel provides greater corrosion resistance and may be required in external, damp or exposed applications. Always select the material to suit the environment and plastering system.

What size plasterboard stop bead do I need?
The correct size depends on the required plaster depth and bead profile. Thin-coat systems may use a 3mm stop bead, while deeper profiles are available for applications requiring a greater finish depth.
