5 Coating Systems

5.1 Coating /Rendering

The proprietary coating systems consist of polymer-modified cement renders, which must be finished with an acrylic texture and paint. The proprietary coating manufacturer’s instructions and application requirements must be followed at all times. *(Available to download from the QT website) In most cases these coating systems must be applied by an approved applicator. High profile or heavy texture finishes can minimise surface imperfections or glancing light concerns. Light coloured coatings are recommended. Polymer-modified cement renders must not be applied over sealants or control joints.

5.2 Pre – Coating System Inspection

Check all internal and external corners are formed correctly and have good straight lines. Check the first horizontal course, and panels above rooflines have a good clean bottom line. Check weep holes have been installed in the first horizontal course. With a 1.8m spirit level check for variations greater than 3mm in the QT EcoSeries Wall Panels, especially where panels butt together. If variations are found, take the appropriate remedial action eg. rasp to an acceptable level, or re-fix the offending panels. It is important to eliminate large variations, as they may appear under critical or glancing light conditions. If the internal lining has not yet been installed, advise the building supervisor that internal wall lining cannot be installed using nails as the knocking vibrations will transfer through the frame and crack the render coatings (hairline cracking). Hence internal lining must be screwed. After the inspection has been completed, application of the base coat can begin.

5.3 Application of a Polymer Modified Render Base Coat

Trowel an even coat of polymer-modified cement render over the entire QT EcoSeries Wall Panel, embed QT FullMesh into the wet Render, overlapping joints by 100mm minimum. Allow to firm and then screed and or float to a flat and level finish. The purpose of this coat is to even out the substrate and the porosity of the QT EcoSeries Wall Panel. 150mm wide x 300mm long strips of QT 45° Mesh are also required to be set into the base coat at 45° angle across the corner of all windows and door openings into wet render. Do not render or texture over control joints. The above is a generic guide only. Refer to the proprietary coating manufacturer’s instructions for a detailed description of application. Any proprietary coating system specified must meet or exceed the performance criteria of the BCA.

1.0 Introduction

CSR Panel Systems is a division of CSR Building Products Limited, one of Australia’s leading building products companies.

CSR Panel Systems manufactures Hebel Autoclaved Aerated Concrete (AAC). The AAC in Hebel products is manufactured from sand, lime and cement to which a gas-forming agent is added. The liberated gas expands the mixture, forming extremely small, finely dispersed air pockets, resulting in lightweight aerated concrete.

CSR Panel Systems has manufactured Hebel products that have won wide acceptance as innovative and environmentally preferable building materials. This is due to their lightweight nature, excellent thermal, fire and acoustic properties and design versatility. These inherent properties of Hebel products help achieve quick and cost efficient construction practices as well as providing for comfortable operating environments inside the buildings all year round.

Build a premium home with Hebel PowerBlock 

Hebel PowerBlocks are large AAC Blocks with a standard face dimension of 600mm x 200mm, laid in much the same way as bricks but using Hebel Adhesive to form a monolithic structure. Typically, external walls use a single skin of 250mm thick blocks while internal, non-loadbearing walls use 100mm thick blocks. Hebel’s tight manufacturing tolerances deliver beautifully flat, true surfaces that are easily rendered and painted.

Walls built with Hebel PowerBlock are strong and durable, providing the security of solid masonry coupled with exceptional thermal and acoustic insulation properties. With over three times the thermal resistance of double brick, Hebel PowerBlocks exceed the Building Code of Australia (BCA) for energy efficiency regulations for zones 1,2, 3 and 5 without the need for additional bulk insulation.

Hebel PowerBlocks are non combustible and can achieve an Fire Resistance Level (FRL) of up to 240/240/240.

For detached houses, this is well above the requirements for building right up to the boundary line and making Hebel an ideal choice for bushfire prone areas.

Compared to traditional double brick construction, Hebel PowerBlock walls can be laid much faster, saving building time and costs. Building with Hebel Blocks may create more internal floor area for the same building dimensions.

Hebel Lintels can be used over windows, doors and garage door openings. Hebel also supplies sill blocks for under windows to complement the overall look of your home.

6.0 Design Approach

There are 2 methods of construction – typical and tie-down. Typical is the most common method of building whilst the tie-down method is required for cyclonic or high wind areas (as determined by an engineer). This guide provides information for both building methods.

Important Note

It is the responsibility of the architectural designer and engineering parties to ensure that the information in the Hebel PowerBlocks Design and Installation Guide is appropriate for the intended application. The recommendations of this guide are formulated along the lines of good building practice, but are not intended to be an exhaustive statement of all relevant data. Hebel accepts no responsibility for or in connection with the quality of the recommendations or their suitability for any purpose when installed.


The Hebel PowerBlocks Design and Installation Guide has been created to provide information for detached residential buildings. The design information in this guide has been condensed from the Hebel Technical Manual and AS3700 Masonry structures. The design basis is AS3700 Masonry structures, Section 12 Simplified design of masonry for small buildings. The footing and slab design is based on AS2870 Residential slabs and footings – Construction.

Refer to Table 6.1 for Building Geometry Limitations.

Design Parameters

The structural design information in this guide is based on the data and assumptions in Table 6.2, 6.3 and 6.4.

Design Sequence

Fig. 6.1 details Hebel recommendations for how to design a Hebel PowerBlock

Max. roof load width on external wall 3.0m (6.0m rafter/truss span)

Where the building geometry is outside the above limitations, the designer must refer to the Hebel Technical Manual and AS3700 Sections 1-11.
