Plasters are pasty, usually granular masses consisting of a wide variety of materials that are applied using different techniques and can serve one or more purposes according to the application.

Plaster types:

By plaster thickness:
Fine plaster, thick layer plaster, thin layer plaster, render, base plaster, finishing plaster, spray plaster

By surface design:

By function:
Insulating plaster, renovation plaster, wall plaster, blocking plaster, foundation plaster, finishing plaster, compress plaster

By plastering technique:
Roll plaster, smooth plaster, coating plaster, felt plaster, trowel coating plaster

Function of the fibre:
Depending on the type of plaster, fibres are used in different fibre types and lengths. Moisture regulation. The fibres increase the level of protection against penetrating moisture.

Weather protection
To protect from storms, heavy rain and heat, fibres must be added to the plaster matrix. The use of fibres makes the plaster more resistant and avoids stress cracks from differing temperatures (direct sunlight).

Flexibility
The exterior plaster is very elastic. This is beneficial because it compensates for stresses in the masonry. The fibres used are responsible for the flexibility and elasticity of the plaster.

Optics and aesthetics
Whether dyed or painted over, whether yellow, red or bright white – another function of fibres in exterior plaster is the visual appearance.
