Rendering Costs

Cement render costs $30–$50 per m² in Australia. Acrylic render runs $40–$65 per m². Silicone render ranges from $55–$90 per m². Texture coat is the most affordable at $20–$40 per m². Prices vary by render type, substrate condition, and access requirements.

Cement (sand and cement) render is the traditional, lower-cost option. It is hard and durable but more prone to cracking with movement. Acrylic render is polymer-modified, making it more flexible and crack-resistant. Acrylic systems also accept integral colour pigments, reducing the need for painting. For most Australian homes, acrylic render offers better long-term value despite the higher upfront cost.

Quality acrylic or silicone render on a well-prepared substrate can last 20–30 years before requiring major attention. Cement render may show cracking earlier, particularly on homes with minor structural movement. Texture coats and painted render typically need a refresh coat every 8–12 years. Regular visual checks and prompt repair of cracks extends render life significantly.

Lime render is a traditional breathable render made with hydraulic or non-hydraulic lime instead of Portland cement. It allows moisture to pass through the wall, which is critical for older solid-wall buildings, stone, heritage brick, and mud-brick substrates. Using rigid cement render on these substrates traps moisture and causes damage. Lime render costs more and takes longer to apply but is the correct choice for heritage applications.

Yes — external rendering is one of the most visually transformative home improvements. A fresh render can lift street appeal, protect weatherboard or aging brick from moisture, and contribute to perceived property value. Real estate agents commonly cite rendered homes as attracting stronger buyer interest. The ROI depends on property type and local market but is generally considered a strong cosmetic investment.

A standard rendering quote includes materials (base coat and finish coat), labour for application to agreed wall areas, and basic clean-up. Scaffolding is commonly excluded and charged separately. Removal of old render, substrate repairs, bonding agents, and painting are also usually separate unless specifically included in the written quote.

A full single-storey house render typically takes 3–5 days. A double-storey home takes 5–8 days depending on the number of coats and complexity. Render requires drying time between coats — usually 24 hours minimum. Curing to full hardness takes several weeks, though the surface can be painted after approximately 7 days on most acrylic systems.

Yes. Rendering prices have risen 27–32% since 2023 across all render types. The primary drivers are labour costs (experienced renderers are in short supply), scaffold hire increases of 15–20%, and material cost inflation on cement, sand, and acrylic additives. Expect a further 4–6% annual increase through 2027.

You can apply new render over existing render only if the old surface is sound — no cracking, hollow spots, or delamination. A texture coat or acrylic overlay is the most common approach for refreshing sound existing render. If the old render is failing (cracking, popping off, or hollow when tapped), it must be removed (hacked off) before new render is applied. Hack-off adds $20–$45 per m² to the project cost.

Autumn (March–May) and spring (September–November) are the best seasons for rendering in most of Australia. Render needs mild, dry conditions to cure properly — temperatures between 10°C and 30°C are ideal. Avoid rendering in extreme heat (above 35°C) as the render dries too fast and can crack. Winter rendering is possible in warmer climates but risky in southern states where frost or prolonged rain can damage fresh render.

Single-storey rendering can sometimes be done from ladders or hop-up platforms, but scaffolding is strongly recommended for safety and quality. Double-storey rendering always requires scaffolding — budget $1,500–$4,000 depending on the perimeter length. Scaffolding is usually quoted separately from the render work itself. Coordinating scaffold hire with painting or other facade work in one hire period saves money.

Inspect rendered walls annually for hairline cracks, especially around windows, corners, and expansion joints. Repair small cracks promptly with flexible filler to prevent moisture ingress. Clean rendered surfaces every 2–3 years with a low-pressure wash to remove dirt and mould. Repaint painted render every 8–12 years. Silicone renders are self-cleaning and require the least maintenance. Avoid high-pressure washing which can damage the render surface.
