Thinking of painting your home’s exterior? Australia sees some pretty wild weather, but even if you aren’t at the mercy of a Cairns cyclone, you’re still likely to be suffering through the heat in summer. Even temperate cities like Melbourne are cresting 40 for days at a time in January, so make sure you, your house and your new paint is up to the task.
The first thing you have to do is pick the right paint for the job. In high temperatures, paints will dry faster. It’s as simple as that. The important thing is ensuring that they don’t dry so fast that they make it impossible to cover the surface evenly and show all of your brushwork. Many mixers will be able to add hot weather additives to the paint which will slow the process down for when you absolutely cannot avoid painting in extreme heat, which can cause blistering in low humidity and peeling in high humidity.
Many paints can be custom-mixed for certain climates, ensuring that you have the greatest chance of getting the job right the first time. You won’t be able to just put up any old tin of off-white, though. You’ll have to go to a professional.
Protecting yourself and your project
Slip, slop, slap isn’t just the sound of a painter hard at work, it’s a vitally important reminder for anyone working outdoors in the heat. If you’ve already gotten the heat-additive treated paint and the only day you’ve set aside is a blistering 42 degrees, you don’t have to abandon your plans. Even though they may not look like much, setting up simple shades and awnings for where you’re working can dramatically cut the temperature both on you and on the wall you’re working on.
When it comes to exterior painting, surface temperature is much more important than ambient air temperature. A wall in the sun can be as much as 25 degrees hotter than the surrounding air. If you can keep the worst of the sun off a surface, you’ll not only be able to work longer and safer, you’ll likely do a much better job. Paint requires a certain amount of liquid to set cleanly, and if hot weather removes this, the pigment and resin particles can fail to fuse, meaning a cracked paint job.
In cases like this, it can be worthwhile considering changing your approach. Hiring a paint sprayer can mean a much more even coat that’s less likely to be visibly affected by the heat. They’ll also likely make the work go faster, meaning less chance of you suffering from heatstroke or heat distress.
A little forethought goes a long way
Painting the exterior of your home is a big job even in perfect weather. Guard against failure by looking at the forecast, having a back-up plan and being ready to abandon the work if it’s just impossible to get the job done right. Don’t create more work for yourself. Do your homework and make sure you’re working with the best tools.
