When to Paint Weatherboards & Why You Shouldn’t Wait Too Long

Weatherboards are a classic and durable choice for Australian homes, but they need regular maintenance to stay in top condition. If you wait too long to repaint your weatherboards, they can start to crack, peel, and deteriorate, leading to costly repairs. Knowing when to repaint your home’s exterior will help protect it from the elements and keep it looking fresh for years to come.

How Often Should You Paint Weatherboards?

The ideal time to repaint weatherboards depends on several factors, including the type of paint used, the climate, and how much sun exposure your home gets. As a general rule:

• Every 5–7 years for homes in coastal or high-exposure areas.

• Every 7–10 years for homes in mild climates with minimal weather extremes.

• Every 3–5 years if the last paint job was done with low-quality paint or poor surface preparation.

If your weatherboards were painted with a high-quality exterior acrylic paint, they will typically last longer than oil-based paints, which tend to crack over time.

Signs It’s Time to Repaint Your Weatherboards

If you’re unsure whether your home needs a fresh coat of paint, look for these warning signs:

1. Peeling or Cracking Paint

Once paint starts to peel, moisture can seep into the timber, leading to rot and structural damage. Addressing this early prevents costly repairs.

2. Fading or Discolouration

Harsh sun exposure can cause paint to fade over time, making your home look worn and outdated. Lighter colours tend to last longer, while darker shades fade faster.

3. Timber Exposed or Weathering

If the paint has worn away and bare wood is visible, your weatherboards are vulnerable to moisture damage, leading to warping or rot.

4. Cracks or Gaps in the Boards

Small cracks or gaps can let water in, which can expand in colder months and cause further damage. A fresh coat of paint helps seal and protect the timber.

5. Mould, Mildew, or Water Stains

If you notice mould or mildew forming on your weatherboards, it could indicate trapped moisture. Repainting with mould-resistant exterior paint can help prevent future issues.

Why You Shouldn’t Wait Too Long to Repaint

Delaying a repaint can cause bigger problems down the track. Here’s why acting sooner rather than later is essential:

• Prevents timber rot – Once moisture penetrates the wood, it can lead to rot, requiring costly replacements.

• Saves money on repairs – Repainting before the damage worsens is far more cost-effective than repairing or replacing weatherboards.

• Improves street appeal – A well-maintained exterior boosts your home’s curb appeal and value.

• Protects against extreme weather – High-quality exterior paint acts as a shield against UV rays, rain, and wind.

Best Time of Year to Paint Weatherboards

In Australia, the best time to paint weatherboards is during mild, dry weather, typically in:

• Spring or early autumn – Ideal temperatures and lower humidity allow for proper paint curing.

• Avoid extreme heat or rain – Painting in high heat can cause paint to dry too quickly, leading to cracking, while rain can ruin a fresh coat.
