Gyprock Aquachek 


Gyprock Aquachek is part of Gyprock's specialty range of plasterboards. This gypsum plasterboard’s core, face and back are treated to make it resistant to moisture and humidity without compromising integrity. It is specifically designed for use as a lining in wet areas of residential or commercial buildings.

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

Gyprock manufactures other plasterboards with moisture resistant properties that may satisfy a wider range of performance requirements:

Gyprock Fyrchek® MR

Ceminseal Wallboard

Gyprock Aquachek is manufactured in Australia to Australian Standard AS2588 and the heavy-duty face paper is a blue colour.

Product Options

Gyprock Aquachek is available in 10mm and 13mm thicknesses and in 1200mm and 1350mm widths. The long edges are recessed for flush jointing.

In a horizontal setout, the 1200mm sheet width suits standard 2400mm ceiling heights and 1350mm suits 2700mm ceilings. In commercial applications, plasterboard is often installed vertically to cater for higher ceilings.

Gyprock Aquachek 10mm

Aquachek 10mm is predominantly used for residential walls and ceilings in wet area installations, where door frames and window reveals are generally designed for a 10mm internal lining. Aquachek satisfies the requirements of the Building Code of Australia for wet area wall linings. Refer to the Australian Standard AS3740 – Waterproofing of Wet Areas in Residential Buildings for additional requirements.

More information about wet area solutions in homes can be found under the Solutions tab.

Typical applications:

  • Bathrooms
  • Laundries
  • Ensuites
  • Toilet rooms
  • Ceilings of walkways and verandahs

Gyprock Aquachek 13mm

Aquachek 13mm is generally used for wet area walls in commercial environments where a more robust lining is desired.

Typical applications:

  • Showers/ Change Rooms/ Rest Rooms
  • Commercial laundries and kitchens
  • Hospital ward bathrooms
  • Soffits

Plasterboard Manufacture

Gyprock Aquachek is manufactured to AS/NZS 2588 Gypsum Plasterboard. Gyprock factories conduct regular testing under a Quality Management System complying with ISO 9001/2000.

Plasterboard Installation

AS/NZS2589: Gypsum linings – Application and Finishing outlines the procedures for the installation and finishing of Gyprock Aquachek in conjunction with additional details contained in Gyprock Technical Literature.

Levels of Finish

A Level of Finish sets out the minimum specifications for installation processes from framing preparation to painting and decoration. The levels are defined in AS/NZS 2589.1, and are intended to provide builders, installers and homeowners with defined methods and practices necessary to meet expectations in terms of the Level of Finish. They are not applicable to fire rated construction.

The level of finish should be specified prior to construction as it can be affected at different stages of construction and tolerances must be adhered to:

  • Frame construction

  • Plasterboard fixing and back-blocking

  • Plasterboard jointing and setting
A Level 3 Finish is for areas that do not require painting and decoration such as above ceilings and inside service shafts.

A Level 4 Finish is the generally accepted level for domestic construction

A level 5 Finish should be specified wherever gloss, semi-gloss or dark coloured paints are to be used, or where critical glancing light conditions are likely.

More information on Levels of Finish can be found in the Gyprock Residential Installation Guide

Painting and Decoration

Finishes applied to plasterboard surfaces can have a significant effect on the perceived quality of the installation, particularly where critical lighting conditions exist.

  • Textured or heavy patterned finishes tend to hide imperfections
  • Matt finishes minimise imperfection visibility

  • Semi-gloss and gloss finishes highlight imperfections

  • Light colours are less likely to show imperfections and impact damage

Gyprock recommends paint systems consisting of one coat of a plasterboard sealer followed by two coats of finishing paint. Always follow the manufacturer’s instructions for application and recoating.

Gyprock recommend decoration in line with Master Painters Australia.
