Internal Finishes and external rendering

There are two different types of finish to the building fabric , inherent finishes
Inherent finishes

• Those inherent in the material
• Materials such as timber stone , brick and glass provide a natural finish without any need for further work 
• For example , fair-face brickwork or blockwork without plastering . 

 Applied Finishes 

• Those appplied to a background 
• Application of materials to existing backgrounds such as plaster to a wall or paint to timber . 

The primary function of a surface finish is to provide a durable , visually attractive and low maintenace surface to floors , wallls and ceilings
There may be differences between the functional requirements of the finish depending on whether it is external or internal finish .
