AAC panels & blocks

Hebel Rendering, Adelaide

Hebel, the lightweight AAC panel and block system, needs a render system made for it: a base coat with reinforcing mesh, then a flexible finish, so the joints and panel edges don’t show through as cracks.

Rendering Hebel the right way

AAC isn’t rendered like brick. It takes a render system made for the panel: a base coat with reinforcing mesh through it, then a flexible acrylic finish. Dino renders Hebel panels and blocks across metro Adelaide and some rural areas.

That mesh-reinforced base is what stops joints and panel edges showing through as cracks later. Skip it or rush it and the finish shows it.

What Hebel is

Hebel is a brand of autoclaved aerated concrete (AAC) — lightweight panels and blocks used widely on Adelaide new builds, upper storeys and extensions. It’s quick to build with and insulates well, but the raw surface has to be rendered to be weatherproof and finished.

—What it costs

What drives the cost of rendering Hebel

Hebel has to be rendered to be weatherproof, so the render is part of finishing the build rather than an optional upgrade. It is quoted per job, and the panels being flat and consistent generally helps.

What adds work is the detail: joints, corners, penetrations, and any panel damage left over from the build all need attention before the finish coats go on.

  • Panel area and the number of joints, corners and openings to detail
  • Jointing, mesh and base-coat work across the panels
  • The condition of the panels, including any damage left from construction
  • The finish chosen over the base coat — acrylic, texture or a trowelled finish
  • Height, access and scaffold, especially on upper storeys

Hebel Rendering: your questions

Does Hebel need rendering?

Yes. Raw AAC has to be coated to be weatherproof and finished, and a simple coat of paint isn’t enough. Hebel takes a render system made for the panel: a base coat with reinforcing mesh through it, then a flexible finish coat. Dino renders Hebel panels and blocks across metro Adelaide and some rural areas, and quotes are free.

How much does it cost to render Hebel in Adelaide?

Joins, corners and openings drive much of the cost on Hebel, because each one needs detailing before the finish coats go on. The panel area, the condition of the panels, the finish you choose on top, and height and access count too. Hebel has to be coated to be weatherproof, so it’s best priced as part of finishing the build. Quotes are free.

What render goes on Hebel?

A render system made for AAC rather than a plain sand and cement render: a base coat with reinforcing mesh through it, then a flexible acrylic finish. AAC is lightweight and porous, so it pulls the water out of an ordinary cement render before it can cure, which leads to cracking and poor bonding. That’s why it’s worth using a system the maker rates for the panel.

Why does Hebel render crack?

Usually because the wall moves at the joins and the render system can’t take it. Common causes are a skimped base coat or missing mesh, render run over control joints instead of stopping at them, and movement where Hebel meets another material, such as an existing brick house. Control joints filled with a flexible sealant are meant to take that movement, and the coating needs to bridge small cracks.
