Gyprock™ Aquacheck®

Gyprock Aquachek is a moisture resistant wall and ceiling plasterboard designed as the perfect lining for wet areas. It is available in 10mm and 13mm thicknesses for residential and commercial applications.

Typical Applications

In residential projects Gyprock Aquachek is ideal for use in bathrooms, laundries, ensuites, toilets and protected external ceilings like soffits and verandahs.

In commercial projects Gyprock Aquachek is typically used in showers/change rooms, restrooms, laundries and kitchens, hospital ward bathrooms and soffits.

Because Aquachek is not subject to moisture movement and has extremely low water absorption characteristics, it provides an excellent, stable substrate for ceramic tiles.

The core, face and back of Gyprock Aquachek are treated to make it resistant to moisture and humidity without compromising integrity. It is specifically designed for use as a wall and ceiling lining in wet areas of residential or commercial buildings. It can be easily identified by its blue coloured face paper.

Aquachek satisfies the requirements of the Building Code of Australia for wet area wall linings in residential and commercial buildings.

Tested Moisture Performance

Gyprock wet area plasterboard products are manufactured with special additives to enhance the moisture resistance of their core. The additives also permeates the face and back paper of the board, delivering superior performance in wet area and high humidity applications.

Water resistance
Water resistance is tested by submerging a sample of plasterboard in a body of water for two hours.

Surface water resistance
Surface water resistance testing sees the plasterboard sample weighed pre-and-post surface exposure to water.
