Cold, wet winters slow drying times, coastal conditions accelerate paint deterioration, and condensation leads to mould inside the home. Without the right paint, even a freshly completed project can start showing signs of wear within months.

The climate of Australia’s southern states demands paint that is made to last in moist, salty, and cold conditions. That’s why Haymes Paint, a family-owned, Australian-made company with over 85 years of expertise, develops premium paints specifically for Australian weather. Whether you're painting a home’s exterior, an interior prone to moisture, or metal surfaces exposed to salt air, choosing the right paint can mean the difference between a long-lasting finish and one that fails too soon.

Why Australia’s Climate Requires Premium Paints

Cold Temperatures and Slow Drying

Paint dries significantly slower when the temperature drops below 10°C, increasing the risk of adhesion issues. If paint doesn’t properly bond to the surface, cracking and peeling are far more likely.

Moisture, Condensation, and Mould Growth

Melbourne experiences (on average) 135 rainy days each year (Climate of Melbourne), Adelaide averages 121 days (Climate of Adelaide), and Tasmania averages 151 days (Climate of Tasmania) creating prolonged dampness. Poor ventilation inside homes results in condensation forming on walls and ceilings, encouraging mould and mildew growth, particularly in bathrooms, kitchens, and laundries.

Salt Exposure in Coastal Areas

Salt-laden air in coastal regions accelerates paint breakdown, leading to chalking, blistering, and fading. Metal surfaces corrode faster in these conditions, requiring specialist rust protection to prevent structural damage.

What to Look for in Paint for These Conditions

For a long-lasting finish, paint must offer:

• Moisture Resistance – Essential for both exteriors and interiors to withstand wet conditions.
• UV and Weather Protection – Prevents peeling, cracking, and fading in extreme temperatures.
• Mould and Mildew Resistance – Reduces growth in damp, poorly ventilated areas.
• Rust Prevention – Crucial for coastal homes and metal surfaces.

Best Paints for Australia’s Southern Climate

For Exterior Protection: Ultra Premium Solashield® Exterior

A home’s exterior is constantly exposed to wind, rain, and temperature fluctuations, requiring paint that holds up in these conditions.

• Self-priming technology on most surfaces, reducing preparation time.
• Superior UV and moisture protection to prevent peeling, cracking, and chalking.
• Mould and salt resistance, making it ideal for coastal and wet climates.

For Interior Durability: Ultra Premium Expressions® Interior

Homes in the south often struggle with dampness and condensation inside, particularly in bathrooms, laundries, and kitchens. Haymes Expressions® Low Sheen is designed to combat these conditions.

• Mould and mildew resistance, preventing stains and deterioration.
• Washable, scuff-resistant surface, making it easy to maintain.
• Durable finish that holds up in high-humidity environments.

For Metal Protection: MetalPlus Universal Primer

Coastal regions expose metal surfaces to high humidity and salt corrosion, increasing the risk of rust. Haymes Paint MetalPlus Universal Primer provides exceptional rust prevention by:

• Delivering high build coverage for long-term durability.
• Fast-drying, making it suitable for rapid application in changing weather conditions.

Expert Tips for Painting in Cold and Coastal Climates

Even the best paint will fail without proper application. Follow these expert tips to ensure a professional, long-lasting result.

1. Choose the Right Season for Painting

The best time to paint is in late spring or early autumn, when temperatures are moderate and humidity is lower. Avoid painting during winter, as moisture in the air slows drying time. 

2. Apply Paint in Thin, Even Coats

Thicker coats take longer to dry, increasing the risk of poor adhesion and peeling. Applying thin layers and allowing proper drying time between coats prevents these issues.

3. Use Premium Paints That Adapt to Temperature Changes

Paint naturally expands and contracts with temperature shifts. Using high-quality, flexible paints, such as Ultra Premium Solashield® Exterior, ensures the finish remains intact without cracking.

4. Prepare Metal Surfaces Thoroughly Before Painting

Rust-prone surfaces should be cleaned before painting. For best results:

• Remove rust and debris with sanding or a wire brush.
• Apply MetalPlus Universal Primer to improve adhesion and extend longevity.
• Finish with MetalPlus Cold Gal for long-term corrosion resistance.
