Chicken wire has specific properties for plastering use. Chicken wire mesh is formed by twisting two adjacent wires at least four times, forming a strong honeycomb mesh structure.
So, it has high strength and durability. Using it when plastering, effectively prevents plaster layer drying out and cracking.
Chicken mesh used for plastering purpose has three different types
- Wire Mesh
- Fibreglass Mesh
- Plastic Mesh
As per below, different types of wire mesh are:
Light Expanded Metal
This is manufactured from sheet steel blade, which cuts through and uniformly stretched at cells having like the diamond shape.
So, it has no welds or bends, and is durable and very strong, with a low weight. This ribbed surface makes it has the max adhesion.
Plaster Chicken Wire
This chicken wire mesh is formed by twisting both adjacent wires at least four times, creating a strong honeycomb mesh structure. So, it has high durability and strength.
Its hexagonal shape prevents the formation of internal stresses. Because of its flexible structure, chicken wire mesh is convenient for mounting on angled and curved surfaces. Its other benefits are twisted mesh, no risk of injury at work, and improved corrosion resistance.
As its mechanical properties and special physical, chicken wire is ideally suited for reinforcement plastering in construction, reinforcement waterproofing, leveling floors, and facade work.
Welded Wire Mesh
The welded wire mesh used for inside plastering work. The welded wire mesh is primarily made of thin, low-carbon drawn wire or galvanized wire with a dia. of 1.5mm to 0.4mm, located in mutually perpendicular directions and interconnected by spot welding. Its wire diameter is much smaller than this standard welded wire mesh. The welded mesh plastering has a wide scope. It may be used for the building outside and inside the plaster reinforcement.
If used for interior plasterwork and no corrosion material, needs no galvanizing, common carbon wire mesh will work well.
Plaster fibreglass mesh protects the wall surface. The fiberglass mesh is a cheap material that doesn’t burn and is characterized by low weight and high strength.
These properties allow it to be successfully used at this formation of plaster facades, as well as use on ceiling surfaces and internal walls. This material is widely used for fastening this surface layer in the corners of the room.
The resistant to alkalis don’t decompose and will not rust overtime, it doesn’t emit toxic and harmful substances, has a high resistance to tearing and stretching, protects this surface from cracking and improves its mechanical strength.
Plastic mesh used to plastering to a brick wall. The plaster plastic mesh for fast-drying dry mixes plastering. Plastic mesh is recommended for plastering internal and external.
Perform this function of protection against the formation and reinforcing mesh of surface crevices and cracks, increase its mechanical strength, and prevent deformation.
However, its scope isn’t limited to Plastering.
The plastic plaster mesh is also successfully used at painting works and plastering by pouring floors, for sound insulation and heat wall surfaces, for the reinforcement of door and window frames, to protect the facades.
A specially recommended for plaster using fast-drying dry mixes, plastic mesh with large mesh is an alternative to metal plaster mesh.
Why Chicken Mesh is used for Plaster?
To prevent a crack in plastering work we use chicken mesh at the junction.
Chicken mesh has this same function as reinforcement does in concrete. It strengthens the plaster against forces.
Mainly to avoid the crack formed due to insufficient gap filling between RCC column & Brick wall joint.
Therefore we used chicken mesh in plastering, and also due to this, there will a proper bond formation between finishing surfaces of the RCC column & Brick wall.
Chicken mesh in old plaster was used to prevent cracking and hold the plaster together should the house experience settlement.
