Exterior paintings in Australia need to be determined by the nature of the weather, which helps in indicating the longevity of the work. With vast geography and different climates ranging from tropical north through temperate south affect how the paint is applied, including its drying time and overall finish. In this blog, Australian Painting, one of the best painters in Northern Beaches will cover how Australian weather affects exterior painting of the buildings and explore how to deal with these challenges for the best results.

The Impact Of Weather On Exterior Painting:

High Temperatures: 

The central and Western part of the country, the temperatures can go up to 40°C in summer. High temperatures cause the paint to dry too fast, resulting in poor adhesion, uneven finishes, and visible brush strokes. It can also cause blisters or bubbles in the paint because of heat action that absorbs moisture onto the surface.

Low Temperature: 

When temperatures have dropped to as low as 10°C or 50°F, it takes much time to dry, making them sticky for extended periods, and thus, dust and dirt start settling on the finish. Sometimes, when the temperature has gone down extremely low, paint fails to dry correctly, compromising durability.

High Humidity: 

The air with more than 70% humidity allows moisture into the painted surface. This can cause streaking, improper adhesion, and a longer period before drying. Hence, streaking in wet paint or peeling due to rain or dew can accumulate more dirt and debris before the paint is dry.

Low Humidity: 

While low humidity is desirable to many, it might cause the paint to dry too fast, especially during hot temperatures. The paint dries before settling, thus causing uneven coverage and a far from smooth texture.

Rain: 

The most obvious threat rain poses to exterior painting is rain itself. Painting on a day when it is going to rain creates streaking, improper adhesion, and an all washout of wet-on-wet fresh paint. Hence, it is essential to check out the weather forecast and ensure at least 24-48 hours of dry weather should be expected. In this way, the surface will remain dry and provide time for drying, which needs to cure up so that it will not get wet before it can dry and cure up. Rain-saturated surfaces need enough time to dry before they get painted. However early the sun may appear after rain, moisture can be trapped inside the surface, which may result in problems with adhesion and peeling very soon.

Seasonal Timing For Exterior Painting

The best time to undertake an exterior painting project in Australia depends on the region:

• In southern or coastal areas, the best time to paint is early fall or spring. The temperatures are a little cooler, the humidity is not as overwhelming, and avoid the month of winter.

• In northern and tropical areas, exterior painting is best during the dry season, usually May to September, since the rainy season has much more rainfall and humidity than the dry season.

• The ideal time for exterior painting in central and western parts of Australia is early spring or autumn. It is because around this time the temperature is moderate, wind is calmer, and are not extremely hot or cold.

Exterior painting works in Australia require weather. Indeed, it is challenging work in every weather condition as it affects temperature, humidity, wind, and, at times, rain.
