Dry lining is a system for cladding the internal faces of buildings, such as walls and ceilings. Plasterboard is attached to the internal faces, creating a smooth surface that finishes such as paint can be applied to directly, a 'wet' plaster finish is not required.

Skimming means to use a finishing plaster either on new plasterboard, or over existing walls or ceilings, to create a smooth finish for painting or wall papering.
