Need To Paint In Extreme Weather? Here’s How…

Painting is one thing, but painting according the the weather is another thing altogether. Paint is very sensitive to temperature, wind, and moisture. Extreme weather will dramatically change the way you need to apply paint.

Let’s break down the ways that your painting technique needs to change according to the weather. 

Painting In Hot Weather

Professional painters get paid to paint. That means that we need to find creative ways of powering through inclement weather – or we would never get anything done! 

There are a few ways we paint in hot weather. The first is to put more thinner in the paint than the recommended limit. For most paints, the recommended limit is 20% thinners. So, if we have a 4L can of paint, we would normally not add more than 800mL of thinner. For more information, check out our guide to using thinners.

At first, experiment with the upper limit. If it still dries off too quickly, add another 100mL at a time. 

On really hot days or on surfaces that dry quickly such as Fibre Cement (Cement Sheet), I add 30-40% water.If that means that more coats will be required for it to cover, but so be it. It doesn’t take that much longer, because it’s faster to apply per coat. 

Painting in Extreme Cold/Snow

Painting in temperatures below 10°C is a whole different ball-game. Most manufacturers of Australian paints don’t recommend painting their products in temperatures below 4ºC. Paints in Britain and America are different – they’re manufactured for colder climates. 

When working with Australian paints, be sure to keep an eye on the ambient temperature. If the temperature is likely to reach 4º before the paint dries, discontinue until the weather warms up. 

Working in the rain

Rain is considered the enemy of the painter. Painting in wet weather should of course be avoided! However, in a world where dollars need to be made, painters often try to push through. 

Rain on paint might look good on glass, but it doesn’t look good on your back pocket. Paint with care in harsh weather.

If you must paint during light rain, keep the following in mind: 

If light rain falls on wet paint, it’ll bring up the tint and leave marks. Acceptable for under-coats, obviously not advisable for the final coat. 

A rule of thumb should be that if rain seems likely, postpone if possible. 

Pushing through to paint in extreme weather can cost you lots of money in material and time.

Painting In Windy Weather

It’s pretty self-explanatory. There are a couple of things to keep in mind, however. 

  1. Be sure to fasten all extension ladders and A-frame ladders. 
  2. Keep brush strokes tight and small, as the paint will dry quickly, especially in hot weather. 
  3. Add thinner to the paint. 

The next time you’re faced with inclement weather, throw these tips in your back pocket – you’ll be ready to tackle the elements fearlessly! 

Happy decorating.
