Residential Installation Guide
This guide provides detailed installation information for the fixing of Gyprock™ plasterboards in residential construction, and includes wet area applications.
For additional information or assistance with plasterboard fixing, please contact the Gyprock™ office in your region.
Applications
Gyprock™ plasterboard is used as an internal lining board to provide smooth, strong, long-lasting walls and ceilings for homes, offices, hospitals, hostels for the aged, schools, shops and factories. Its durable surface will accept most types of decorative finishing, including paint, wallpaper and texture compounds.
Joints between Gyprock™ plasterboard sheets are reinforced and concealed to provide a smooth, durable finish to the whole surface. Alternatively, the joints may be covered with a decorative moulding.
Gyprock Aquachek™ can be used in wet areas in accordance with details in the Wet Area Installation section. It can also be used for exterior ceilings and eaves lining, provided the ceilings are protected from the weather.
Levels of Finish
Levels of finish are defined in the Australian/New Zealand Standard AS/NZS 2589.1: ‘Gypsum linings – Application and Finishing.’ Three‘Levels of Finish’ (3, 4 and 5) are defined, and minimum specifications to achieve each level of finish are detailed in the standard.
It should be noted that, generally, domestic applications should be prepared to a minimum Level 4 finish, and this manual details the requirements for that level.
The level of finish specified affects the methods of jointing, particularly butt joints and back-blocking requirements, the number of coats of joint compound applied as well as the fitting and finishing of stopping and corner/angle accessories.
