What Is Chicken Mesh for Plaster?
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.
The hair cracks are mainly formed on the plastering layer. And mainly Hair cracks are often found on the column and brickwork joints. This happens because
Contraction and expansion for concrete occur more when compared to brickworks. Hence there’s a difference between these and thus forms the crack.
Chicken mesh for plaster material virus three different
Types of Chicken Mesh as Per Material
- Wier Mesh
- Fibreglass Mesh
- Plastic Mesh for Plastering
1. Wier Mesh
As per below, different types of wire mess like.
- Light Type Expanded Metal
- Plaster Chicken Wire
- Welded Wire Mesh
- Chain Link Mesh
1.1. Light Type Expanded Metal
The expanded metal used for plastering
The expanded metal mesh is mostly used as a reinforcing material at the interior decoration, and especially when a plastering work, so sometimes referred to as stucco netting.
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.
Each of these materials has its own disadvantages and advantages. But this best currently considered material is the light type expanded metal.
1.2. Plaster Chicken Wire
Small chicken wire mesh
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.
1.3. 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 dia. It 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.
1.4. Chain Link Mesh
Chain link fence used as plastering mesh
The chain link Plastering mesh is a type of light chain link fence used to prevent wall cracks because of temperature changes.
This chain-link fence with its lightweight, thin wire from 2.0mm to 0.5mm and small mesh opening from 5mm to 25mm, this is also called mini or micro chain wire fence.
The man is plastering to a wall using a chain-link fence as support mesh Chain link fence used as plastering mesh.
This is particularly important in this construction of industrial plants, in which these walls are exposed to high vibration impacts as a result of this machine, presses, and other powerful mechanisms.
2. Fibreglass Mesh
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.
This most widely used standard fibreglass plater mesh is the density of 145g/m2 and 165g/m2 for facade work and exterior cladding.
The resistant to alkalis don’t decompose and will not rust over time, 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.
3. Plastic Mesh for Plastering
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 Use Chicken Mesh For Plaster?
To prevent a crack in plastering work we use chicken mesh at the junction. Different material such between column and wall junction where the coefficient of thermal expansion
Different material is different, and because of that, chances of crack after plastering is bound to occur, that’s why we use chicken mesh.
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.
The mesh also helps fight cracks caused by the twisting of plaster laths. Nowadays, I use galvanized wire mesh screwed to old wooden lath to protect my repairs against cracking.
In exterior plastering, you shouldn’t use chicken mesh if the plastering is thinner than 20 mm since the mesh is not galvanized enough and gives you risk for rust expansion, and then the plastering will fall down before it’s due.
