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. Dry lining requires less technical expertise than traditional plastering and required little water, hence the term ‘dry’ lining.
Plasterboard can be fixed direct to the internal face of a wall or ceiling, or can be fixed to a secondary framework of metal or timber attached to the internal face. Each material requires a different fixing technique:
- Dabs of adhesive can be used to attach plasterboard directly to the internal face, which sets swiftly.
- Plasterboard can be attached to metal or timber walls using nails, this is known as tacking.
- If screws are used for the fixing, this is called screwing. Typically screws support plasterboard better than nails.
Plasterboard is available in a wide range of lengths, widths and thicknesses. The larger the plasterboard, the fewer joints, but the harder it is to handle and fit. Plasterboards has a core of plaster which provides good acoustic and fire insulation. Fibres can be added for extra strength and durability. Moisture resistant plasterboards are treated with wax and can be useful when dry lining bathrooms for example.
