Gyprock Aquachek 13mm is a moisture resistant wall and ceiling plasterboard designed as the perfect lining for wet areas in commercial applications.
Product Overview
The core, face and back of Gyprock Aquachek 13mm 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 commercial buildings. It can be easily identified by its blue coloured face paper.
Gyprock Aquachek 13mm is manufactured to meet or exceed the requirements of water resistant grade gypsum plasterboard as per AS/NZ 2588 Gypsum Plasterboard, and satisfies the requirements of the Building Code of Australia for wet area wall linings in commercial buildings when installed according to Gyprock installation guides. Refer to Australian Standard AS3740 - Waterproofing of Wet Areas in Residential Buildings for additional requirements. Installation information for wet area solutions can be found in the Red Book 3: Commercial Installation Guide.
Typical Applications
In commercial projects Gyprock Aquachek 13mm is typically used in showers/change rooms, restrooms, laundries and kitchens, hospital ward bathrooms and soffits.
Because Aquachek 13mm is not subject to moisture movement and has extremely low water absorption characteristics, it provides an excellent, stable substrate for ceramic tiles.

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.
