The best time to paint a roof in Queensland is typically during spring. This is because the weather for this period is usually mild, with less extreme humidity and heat present.
The temperature during springtime is usually around 15 to 28 Celsius with approximately 50% humidity. These conditions allow a fresh coat of paint to dry and cure properly. It also makes for a more comfortable working environment for roof painters than in summer or fall.
In this post, we’ll discuss how long it takes for roof paint to dry, whether or not white paint can reduce the indoor temperature, and if roof coating can prevent leaks.
How Long Does It Take for Roof Paint to Dry?
Roof paint can take 2 to 12 hours to dry to the touch. This time difference will depend on two crucial factors: the temperature and humidity while painting and the type of paint used.
Elastomeric roof paint, a common paint used on roofs, normally takes about 3 to 5 hours to dry to the touch. Recoating will typically be possible after 24 hours.
Meanwhile, acrylic roof paint can dry within 1 to 2 hours. Roof painters can then begin recoating the painted surface after giving it 4 to 6 hours to settle in.
If you plan to use oil-based roof paint, it’s essential to keep in mind that these products will take the longest time to dry. They can take as long as 12 hours to dry to the touch and a minimum of a full day before they can be recoated.
Although roof paint can dry in a matter of hours, it usually takes a few days to cure. This means that the paint will not fully adhere to the roof surface despite being hard to the touch.
Can White Roof Paint Reduce Indoor Temperature?
A white roof can reduce the indoor temperature by reflecting the rays of the sun away from a house or building, helping reduce the amount of heat the structure absorbs overall. That’s why most people consider white the best colour for roof.
This “cool roof” effect is a popular advantage that white-coloured reflective roof coatings are known for. Such paint products are made with lighter pigments so that they can reflect sunlight more than their traditional dark-coloured counterpart.
It’s important to note that the cool roof effect will depend on the types of roof paint that were used, the roof surface, and the colour of the paint products. Paint with higher reflectivity will be more effective at lowering indoor temperature than those with lower values.
Can Roof Coating Stop Leaks?
Roof coating won’t stop leaks. However, it can help fill in the small cracks on a roof’s surface where water can seep through.
Minimising the chances of water getting into one’s roofing system is crucial, as this can cause significant damage over time.
