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 rendering 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
• External rendering and damp-prone areas where suitable materials are used

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 match the thickness of the plaster or render system. Using the correct size helps create a flush finish and a cleaner edge.

• 3mm – for skim and thin-coat plaster systems
• 10mm–13mm – for standard plaster builds
• 15mm–20mm+ – for thicker plaster or render applications

When should I use stainless steel plaster stop beads?
Stainless steel stop beads should be used in external applications or damp environments where corrosion resistance is important.

What size plasterboard stop bead do I need?
