Plasterboard Stop Bead

(2 Products)

Achieving a crisp, straight edge when plastering can be a challenge for both the rookie and professional. Plasterboard stop beads are a helping hand when plastering sharp, neat corners. They utilise a perforated wing as a key to prevent cracking. Used in conjunction with drywall and plastering systems at the intersections of walls, soffits, ceilings, and openings to finish and protect plaster edges, plasterboard stop beads provide a straight edge to finish the plaster against.

What Is A Plasterboard Stop Bead? 

A plasterboard stop bead, also known as a stop end bead, is a thin piece of straight-edged metal designed to create a square-finished edge for drywall and plastering systems.The beads utilise a perforated wing to aid in finishing and reinforcing these skim plaster edges.

The process involves placing the stop bead along the length of plasterboard to ensure smooth and precise corners for plastering over. The perforated metal wing is either bedded or screwed into the background, while the straight edge acts as a depth guide, protecting the plaster edge from impact. 

If you are using the stop beads on a metal lath background, you may utilise tying wire, so long as it is made from the same material as the lath and bead itself (galvanised steel). Simply twist the wire and angle the ends away from the finished coating face. 

Where To Use Plasterboard Stop Beading? 

Here at Materials Market, we stock thin coat plaster stop beads manufactured from 2.4m and 3m galvanised steel. The stop beads we sell are primarily purposed for internal use, providing a neat 3mm finish on plasterboard and smooth backgrounds.

If you are looking to use stop beads in external applications or areas that may be prone to damp or moisture, stainless steel or uPVC should be used.

Frequently Asked Plasterboard Stop Bead Questions

Frequently Asked Questions About Plasterboard Stop Beads

What Should I Consider Before Installing Stop Beads? 

When using stop beads internally, you should ensure to minimise the drying-out period of plaster as much as possible; this is especially important during periods of cold weather. Provide adequate ventilation and heating to the area where necessary. 


It's also vital that all metal beads used in an application are the same type. 

How To Cut Plaster Stop Bead To Length

Mark all of the necessary measurements, then take your tin snips and cut in accordance with your markings using either a hacksaw or tin snips. 
Wearing gloves is essential for this job - especially when using tin snips. The edges that are left behind are incredibly sharp and can easily cut you, so protecting your hands is crucial.

How Do You Secure A Stop Bead?

A stop bead can either be nailed or glued into place. Align and level the stop bead in the desired fixing location, then use special short galvanised nails to nail through the perforated edge into the timber stud beneath the plasterboard. 

Are Stop Beads Necessary?

It is difficult to achieve a professional, smooth finish without stop beads. Stop beads are critical whenever you wish to achieve a straight, uniform edge.

Why Are Stop Beads Galvanise Coated? 

The galvanise coating (which is essentially a layer of zinc) is applied as a preventative measure against rust and moisture. 

What Is The Difference Between Galvanised Steel & Stainless Steel Stop Beads? 

Galvanised steel stop beads are purposed for internal use whereas stainless steel stop beads are purposed for external use.
