One Finish

Gyprock One Finish is a pre-mixed acrylic compound designed to create a uniform surface on interior plasterboard or fibre cement walls and ceilings affected by critical lighting conditions.

Typical Applications

One Finish is rolled or sprayed directly onto the wall or ceiling, eliminating the need for trowel application. It is easy to sand, and where a level of final texture is acceptable, sanding is not required prior to the painting process. A polyester 10-12mm nap is recommended for general roller application, and the product should be allowed to dry for 16-24 hours prior to final painting and decoration. One Finish can also be applied onto already painted surfaces after lightly sanding.

One Finish reduces the difference in porosity, texture and sheen between board and jointing compound, to create a uniform white surface ready for decoration.

Due to its superior hiding power, it can be used as part of a level 5 finish specification under AS/NZS 2589.

Achieving a Level 5 Finish

The application of One Finish over a standard level 4 finish will improve the final surface and minimise the effects of critical light, however it will not automatically upgrade the work to a level 5 finish. A Level 5 Finish under AS/NZS 2589 cannot be achieved without a high degree of preparatory work, and this includes framing/substrate preparation to required tolerances. Visit the Levels of Finish page for more information about how to achieve a level 5 finish.
