How to integrate render into your mixed material home

A “render look” facade gives your home a uniform, uninterrupted seamless appearance,” says Paul Augello, Dulux Acratex®, National Commercial Manager.

It creates the clean lines and calm, matte surfaces that make contemporary homes feel composed. The James Hardie Modern Homes Forecast 2026 puts it plainly: surfaces that combine smooth render and matte finishes balance structural precision with softness and delight. Treat render as the design canvas, then layer texture with care. Here’s how.

What is render? (And what it isn’t)

Render isn’t the wall itself; it’s a system. It sits over a substrate and, when detailed correctly, delivers the flatness and crisp edges a modern facade needs.

Augello explains it well: “Dulux Acratex multi-layered texture coating systems are built up in layers; starting with a levelling coat to smooth the surface, followed by a texture coat that defines the final appearance, and finally protective membrane topcoats.”

Phil Rogers, Technical Sales Leader at Rockcote, adds to this: “Render is a base coat application applied to a substrate that assists in levelling the surface and minimising defects. The base coat render is just as important as the finish you see.”

The render look vs fully rendered homes

Today’s “render look” is less about covering every surface and more about making render an element within a composed, mixed‑material facade.

Miles Howie, National Channel Manager at Sto, believes one of the biggest misconceptions is that render is just what you see on the surface. “In reality, the finish is only as good as what sits behind it,” he says.

“Render works best when it’s treated as the canvas, not the finish… good design comes through, not in how much you render, but how deliberately you use it.”

Mixed‑material facades explained

Smooth rendered forms paired with textured cladding create depth and wow-factor. It’s the contrast that brings a facade truly to life.

“We’re seeing a clear shift toward mixed material facades, where render provides the base and other materials introduce texture and contrast,” says Miles.

Phil agrees: “Render is incredibly versatile. Smooth rendered finishes paired with textured cladding, and textured render balanced with smooth cladding create depth and visual interest.”

Some ideas of where render works hardest:

• Entry volumes for a strong, composed arrival

• Lower levels where solidity and tactile texture is desired

• Garages or side wings to break up bulk and add rhythm

The role of Hardie™ Gravis™ Panel in rendered design

To achieve that crisp rendered look, you need a stable, flat render‑ready base behind the finish. Enter products like Hardie™ Gravis™ Panel.

Hardie™ Gravis™ Panel is an autoclaved aerated concrete (AAC) panel designed to support modern rendered finishes. It’s the dependable substrate that sets up the canvas, working seamlessly alongside James Hardie’s portfolio of fibre cement exterior solutions in a mixed‑material scheme.

What happens if you don’t render properly

Rendering the correct way is essential for a seamless, finished look. If you cut corners you could end up with cracked walls.

“A Dulux Acratex membrane topcoat is the final protective layer in the Acratex multi-layer system,” says Augello. “It forms a tough, flexible barrier that delivers crack bridging protection, resistance to dirt build up, and protects the facade from harsh environmental conditions.”

4 design styles that use render well

Here’s how to use Hardie™ Gravis™ Panel in four key looks from the James Hardie Modern Homes Forecast 2026:

1. Japandi

Using a render-ready panel like Hardie™ Gravis™ Panel in a Japandi home helps achieve a sanctuary of grounded connection. Pair it with Axon™ Cladding and timber accents for warmth and flow.

2. Modern Coastal

Render anchors the Modern Coastal house style with its soft, consistent base. Add Linea™ Weatherboard to contrast without overwhelming the look.

3. Modern Classical

The Modern Classical home brings European symmetry together with approachable detailing, making it the perfect home to experiment with rendered elegance, built on strength. Pair with Stria™ Cladding Fine Texture to complement arches and curves.

4. Box Modern

Monolithic rendered volumes speak wonders in Box Modern homes. Use Hardie™ Gravis™ Panel to articulate upper and lower levels, frame entries or define areas that need to be anchored.
