Has GTEK rebranded to SINIAT?

GTEK™ has been rebranded as Siniat in Australia.

In 2023, Etex Group, a global building materials manufacturer, acquired BGC’s plasterboard and fibre cement businesses, which included the GTEK™ plasterboard range. Following this acquisition, the GTEK™ brand has been integrated into Etex’s Siniat brand portfolio.

This rebranding means that products previously known under the GTEK™ name are now available under the Siniat brand in Australia. The transition reflects Etex’s strategy to unify its plasterboard offerings under the Siniat brand, providing customers with a consistent range of high-quality building solutions.

Is it better to use plasterboard or wet plaster on brick walls?

The choice is dependent on your needs and preferences.

Plasterboard is easy to install, relatively cheaper, lightweight, and ready to paint. On the other hand, wet plaster is easier to mould for complicated designs and can be quite durable if applied properly. However, it can cost a bit more and is labour-intensive to install.
