Frequently Asked Questions About Render Crack Repair in Box Hill North
How much does render crack repair cost in Australia?
Render crack repair typically costs $30 to $80 per square metre in Australia, depending on crack width and how much surrounding render needs cutting back. Small hairline cracks can sometimes be patched with a flexible gap filler from around $6 to $23 a cartridge, while wider cracks need a render mix and a tradesperson.
What causes render to crack?
Render cracks mainly from building movement, shrinkage as the render cures, moisture getting behind the surface, or render applied too thick over a poorly prepared wall. Hairline cracking is common and often cosmetic, but wider or spreading cracks can let water into the wall and should be checked promptly.
Can I repair render cracks myself?
Small hairline cracks can be filled with a flexible exterior gap filler as a temporary fix, but matching the texture and colour of existing render is difficult without the right tools and mix ratio. For a durable, near-invisible repair, especially on wider cracks, a rendering tradesperson gets a better long-term result.
How much does rendering a house cost in Australia?
Cement render costs $30–$60/m² for labour, plus $10–$20/m² for materials. Acrylic render costs $40–$80/m². A standard double-brick home with 200m² of wall area typically costs $8,000–$16,000 fully rendered. Prices vary significantly by region, access difficulty, and surface condition.
What is the difference between cement render and acrylic render?
Cement render is a sand-and-cement mix applied in multiple coats and painted over. It's durable but can crack over time with building movement. Acrylic render is a polymer-modified system that's more flexible, crack-resistant, and available in integral colours — no painting required. Acrylic is the more modern and preferred choice.
Can you render over existing paint or render?
Generally not recommended — the new render needs to bond to a clean substrate. Old paint or loose existing render must be removed first. Surface preparation (cleaning, removing loose material, applying bonding agent) is critical for adhesion. Rendering over a sound, existing render coat is sometimes possible with the right bonding agent.
How long does render take to cure before painting?
Cement render must cure for a minimum of 28 days before painting with a standard acrylic paint. Painting too early traps moisture and causes paint failure. Sealer coats can sometimes be applied after 7 days. Acrylic render systems are integral colour and don't require painting, but can be painted after full cure.
Is rendering suitable for a brick home in Australia?
Absolutely — rendering over brick is very popular in Australia to modernise the appearance of older homes or create a seamless façade. The brick surface must be clean, free of paint, and have open mortar joints to ensure mechanical key for adhesion. A bonding agent is recommended.
