Different types of mesh used in plastering are as follows.
1. Metal wired mesh:
a. Chicken wire mesh:
The name, chicken wire mesh is used as they are used to fence the fouls or chickens in the poultry industry. These meshes have hexagonal or honeycomb-shaped openings, made of galvanized flexible wires.
Chicken wire mesh is a widely used material to reinforce plastering at masonry junctions. The flexibility, shape, & specific properties of these materials make them a more convenient material to choose for plastering work.
b. Welded wire lath:
c. Welded wire mesh:
d. Sheet metal lath:
They are used in the case of pumped or sprayed plaster applications.
In industrial walls, where there is a constant vibration of the machinery, they act as a good reinforcement for walls to prevent vibrational cracks.
e. Expanded metal mesh:
f. Linked chain mesh:
Linked chain mesh is made of low-carbon steel or galvanized wires. The zig-zag pattern wires are woven to form the mesh of the required size. They form diamond-shaped openings after weaving. The size of these openings varies from 5mm. to 25mm.
They are mainly used as a reinforcement to walls before plastering.
2. Fiberglass plaster mesh:
Fiberglass plaster mesh is a lightweight alternative to chicken wire mesh. The main advantage of these materials over metal meshes is their resistance to alkalies & they do not rust.
Fiberglass plaster mesh has high resistance to tearing & stretching & does not decompose over time. Similar to chicken wire mesh, they protect the surface from cracking & improves the bond strength of the plaster.
3. Plastic wire mesh:
Plastic wire meshes are best suitable for the fast-drying types of dry mix plastering. We can use them for both interior & exterior plastering works.
These meshes come with a wide variety of openings such as square, rectangle, diamond, hexagonal, etc.
