Achieving a Quality Finish
No sheet lining has a surface that's perfectly flat or totally free of minor imperfections. These can be minimised however by thinking carefully about the design, the materials used, lighting conditions and underlying framing condition.
Whether you're building or renovating, here are some fundamentals of a quality finish. Learn more
Give your lounge, dining and feature rooms the finish they deserve.
For some rooms such as the lounge, dining and feature rooms, the finish is particularly important. As well as delivering a high-quality interior wall and ceiling finish, the GIB Ultraline® Lining System also adds benefits like noise control, bracing and fire-rated protection for your home.
GIB Ultraline® is 3mm thicker than standard plasterboard, with a dense plaster core reinforced with fibreglass for added strength. The unique Pearlcoat-coated paper is similar to the texture of the joint-filling compound making it easier to stop and paint and thereby minimising the visibility of joints.
Levels of finish
'Levels of finish’ is a guide for specifying the required quality of finish when installing and stopping plasterboard. Levels 4 and 5 are the most commonly specified for home use.
- Level 4: the generally accepted level of finish used when non-critical lighting falls on satin/flat/low-sheen paints or wallpaper.
- Level 5: for use when gloss, semi-gloss or dark-tone paints are specified or where critical lighting conditions occur on satin/flat/matt or low-sheen paints.
How to achieve a Level 5 finish
To remove surface textures and porosity, the entire wall/ceiling must be covered in a thin layer of a special compound called the ‘skim coat’. Stricter framing and installation requirements are needed.
How to achieve a Level 4 finish
For a great Level 4 finish, GIB Ultraline® has a fine, smooth Pearlcoat-coated surface paper that can reduce critical lighting levels.
