Plastering Beads

Plastering beads play a crucial role in ensuring a clean, sharp, and professional finish in plastering work. They are used to create straight edges and protect and reinforce plaster in areas prone to impact or where a sharp, clean line is desired. Here's an overview of the different types of plastering beads and their specific uses:

1. Angle Beads: These are perhaps the most common type of plastering bead. They are used to create sharp and clean edges at corners of walls and ceilings. Angle beads are particularly useful in high-traffic areas where edges are prone to damage, as they provide additional strength and protection.
2. Stop Beads: Stop beads are used to provide a neat finish at the end of a run of plaster. They are often used around doorways, windows, and other openings. The bead acts as a 'stop' for the plaster, ensuring a clean and straight edge.
3. Bellcast Beads (also known as Drip Beads): Bellcast beads are used at the base of walls, typically above the DPC (damp proof course) line. They are designed to help shed water away from the wall, thereby protecting the plaster from water ingress and damage.
4. Movement Beads: These beads are used to prevent cracking in plasterwork due to thermal expansion or contraction, or slight movements in the building. They are typically used over expansion joints or at junctions between different materials.
5. Mesh Beads: These beads are used to reinforce areas of plaster that are prone to cracking, such as around openings or where different substrates meet. They have a mesh wing that gets embedded in the plaster, providing reinforcement and helping to prevent cracks.
6. Arch Beads: Specifically designed for curved or arched structures, these beads help create a clean line and protect the plaster on archways and curved features.
7. Corner Beads: Similar to angle beads, corner beads are used to protect and reinforce the plaster at corners. They are particularly useful in areas where the plaster is susceptible to impact damage.
8. Shadow Gap Beads: These are used to create a shadow gap or a ‘reveal’ detail in plasterwork. They are popular in contemporary designs for creating a minimalist look.
9. Feature Beads: These are decorative beads used to create features in plasterwork, such as recesses or ledges. They can add a unique aesthetic element to a room.
10. Skim Beads: These are thin beads designed for use with skim plastering. They help achieve a fine, straight finish, especially around windows and door frames.

Each type of plastering bead serves a specific purpose in ensuring the durability, integrity, and aesthetics of plasterwork. The choice of bead depends on the specific requirements of the plastering project, such as the location, the type of edge or joint needed, and the level of impact resistance required. Proper installation of plastering beads is crucial for achieving the desired finish and ensuring the longevity of the plasterwork.
