Product Information
Full details
This Expamet galvanised steel stop bead is designed for builders and DIY enthusiasts needing to create clean, professional plaster edges. Its key benefit is providing a strong, straight finish that protects corners from damage. A potential caveat is its 3m length, which may require cutting for smaller projects. The product offers a durable, corrosion-resistant solution for internal plastering applications, featuring a mesh wing for enhanced plaster bonding and structural integrity.

FAQs
What is the primary purpose of a stop bead?
A stop bead is used to create a clean, straight, and protected edge for plaster finishes, particularly at junctions and external corners, preventing damage and improving aesthetics.
Can this stop bead be used for external corners?
This specific product is designed for internal use. For external corners, a different type of corner bead is typically recommended.
How is the bead secured to the wall?
It can be secured using plaster, adhesive, or mechanical fixings like nails or screws through the mesh wing.
What does 'galvanised steel' mean for this product?
Galvanised steel means the steel has been coated with a layer of zinc to protect it from rust and corrosion, making it more durable, especially in potentially damp conditions during construction.
Is it difficult to cut the 3m bead to a shorter length?
Cutting requires appropriate metal cutting tools. Tin snips can work for thinner gauges, but an angle grinder with a metal disc provides a cleaner cut for tougher materials. Always use safety precautions.
How wide is the plastering wing?
The product is described as 60mm wide, which refers to the overall width including the mesh wing, providing a good surface area for plaster adhesion.
Can I use this on a ceiling plaster edge?
Yes, this stop bead is suitable for creating clean edges on ceiling plaster lines where they meet walls or other surfaces.
Troubleshooting
Stop bead is not straight after fixing.
Check that the wall surface is flat. Re-position the bead before the fixing material sets, ensuring it is held level and plumb.
Plaster is cracking along the bead.
Ensure the mesh wing is fully embedded in the plaster. Check that a suitable plaster mix is being used and that the bead is adequately supported. Avoid applying plaster too thinly over the bead.
Difficulty cutting the bead to size.
Use sharp, appropriate metal cutting tools. For thicker gauge beads or multiple cuts, an angle grinder with a metal cutting disc may be necessary. Always wear safety glasses and gloves.
Bead appears rusty.
This is unlikely due to the galvanised finish. Ensure the product has been stored in a dry environment. Minor surface rust from prolonged damp storage can often be wiped off; if significant, consider if it impacts integrity.
Pros and Cons
Pros
- Provides a consistently straight and neat plaster edge.
- Offers superior protection against edge damage.
- Galvanised finish ensures resistance to corrosion.
- Mesh wing aids in strong plaster bonding.
- Suitable for various internal plastering projects.
Cons
- The 3m length may be cumbersome for very small areas or confined spaces.
- Requires careful handling to avoid bending the bead before plastering.
- Cutting the bead to size requires appropriate tools.
Setup, Compatibility & Care
Setup:
- Ensure the surface where the bead will be applied is clean and dry.
- Cut the stop bead to the required length using appropriate metal cutting tools (e.g., tin snips, angle grinder with metal disc).
- Apply your chosen fixing method:
- Plaster: Apply a bed of plaster to the wall and press the bead firmly into it, ensuring the mesh wing is fully embedded.
- Adhesive: Use a suitable construction adhesive applied to the back of the bead or the wall.
- Mechanical Fixings: Use nails or screws through the mesh wing at regular intervals.
- Ensure the bead is straight and level before the plaster or adhesive sets.
- Proceed with plastering, ensuring the plaster covers the mesh wing and feather edges smoothly.
Compatibility:
This stop bead is compatible with all standard gypsum-based plasters and plastering compounds suitable for internal use. It is designed for use on common building substrates such as plasterboard, masonry, and existing render.
Care:
The galvanised finish provides inherent corrosion resistance, requiring minimal maintenance. Keep the product dry during storage. Once installed and plastered, the bead is protected from the elements. Clean any dust or debris from the bead before applying plaster.
