Introduction
Chicken mesh, a honeycomb-like net formed by twisted wires, is a key material used in plaster works. Its unique properties make it an essential component for enhancing the strength and durability of plaster coats while preventing crack formation. This blog explores the purpose of chicken mesh in plastering, different types of chicken mesh, and their specific applications. By understanding the benefits and characteristics of chicken mesh, construction professionals can make informed decisions regarding its usage in various construction projects.
Types of Chicken Mesh
1.Wire Mesh:
- Light Expanded Metal Mesh: Made by stretching a metal sheet to create a diamond-shaped pattern. Provides durability, strength, and maximum adhesion to surfaces.
- Welded Wire Mesh: Thin low-carbon or galvanized wire interconnected by spot welding. Suitable for plastering on uneven and rough surfaces, ensuring smooth and strong plaster.
- Linked Chain Mesh: Also known as mini or micro chain wire fences. Made of low carbon steel or galvanized wire, used to prevent crack formation in walls prone to temperature changes or vibration impacts.
There are three types of Wire Mesh:
i.Light expanded metal mesh
ii.Welded wire mesh
iii.Linked chain mesh
i) Light Expanded Metal Mesh:
Light expanded metal mesh is a diamond-patterned mesh made by cutting and stretching sheet metal. It is commonly used to support plaster or stucco and acts as a reinforcement material for interior decoration. This mesh is known for its durability, strength, and lightweight nature, while its ribbed structure ensures maximum adhesion to surfaces.
ii) Welded Wire Mesh:
Welded wire mesh consists of thin low-carbon or galvanized wire interconnected by spot welding. It is suitable for plastering uneven and rough surfaces, providing smooth and strong plaster finishes. This type of mesh helps prevent crack formation in plaster.
iii) Linked Chain Mesh:
Linked chain mesh, also called mini or micro chain wire fences, is lightweight and used to prevent crack formation due to temperature changes. It is made from low carbon steel or galvanized wire and is commonly applied in architectural interior wall plaster and outdoor wall insulation plaster. Linked chain mesh is also used in structures prone to high vibration impacts caused by machinery.
2. Fiberglass Mesh:
- Lightweight and non-combustible mesh with high strength.
- Resistant to alkalis, stretching, tearing, and rust, making it ideal for plaster facades, internal walls, and ceiling surfaces.
- Offers easy application and effectively prevents crack formation.
3. Plastic Mesh:
- An alternative to traditional metal mesh, suitable for interior and exterior surfaces.
- Enhances mechanical strength, prevents deformation, and offers resistance against cracks.
- Used in plasterwork, paintwork, pouring floors, sound insulation, and protection of facades, doors, and windows.
Purpose of Providing Chicken Mesh for Plastering
- Chicken mesh is primarily used at junctions where different materials meet, such as bricks and concrete or blocks and concrete.
- Due to variations in density, thermal changes can cause differential behavior between these materials, leading to crack formation at the junctions.
- Chicken mesh is applied to minimize or eliminate cracks by providing reinforcement and stability to the plaster.
- It acts as a bridge between dissimilar materials, ensuring a seamless and crack-free surface.
Advantages of Chicken Mesh for Plastering
- Strengthens the plaster coat, enhancing its overall durability.
- Provides reinforcement at junctions of dissimilar materials, reducing the risk of crack formation.
- Improves the adhesion between plaster and the underlying surface.
- Offers flexibility in design and aesthetics, allowing for the replication of various textures and patterns.
- Helps to distribute stress and load evenly across the plaster surface.
- Cost-effective compared to alternative methods of crack prevention.
- Easy to install and compatible with different construction materials.
- Extends the lifespan of plastered surfaces by reducing the need for repairs or maintenance.
Disadvantages of Chicken Mesh
- Potential for improper installation, leading to ineffective reinforcement and compromised durability.
- May require skilled labour to ensure proper placement and adhesion.
- Some types of chicken mesh may be susceptible to corrosion or degradation over time.
- Limitations in terms of flexibility, as chicken mesh may not be suitable for highly curved surfaces or intricate designs.
- Regular inspections and maintenance are necessary to address any signs of damage or deterioration.
Conclusion🎯
Chicken mesh plays a vital role in enhancing the strength and durability of plaster works while preventing crack formation. Its application at junctions of dissimilar materials ensures a seamless and robust surface. By understanding the different types of chicken mesh available, construction professionals can select the most suitable option for their specific projects. Whether it’s wire mesh, fiberglass mesh, or plastic mesh, each type offers unique advantages in terms of strength, resistance, and ease of application. However, it’s important to consider the limitations and potential maintenance requirements associated with chicken mesh to ensure long-lasting and visually appealing plastered surfaces.
