Levels of Plasterboard finish(Euro gypsum / UEEP and ASTM C840)

Key factors in determining the level of finish required:

• Area of the work being done.

• The type and angle of surface illumination

(both natural and artificial light).

• The orientation of panels during installation.

• The type of paint or wall covering being used.

• Method of application.
