Exterior paint needs the right weather to bond and cure properly. Paint applied in the wrong conditions can blister, peel or dry with a patchy finish. Here is how to plan an exterior repaint around Melbourne’s famously changeable weather.
Autumn and Spring Are Usually Best
For most Melbourne homes, autumn (March to May) and spring (September to November) give the most reliable painting conditions: mild temperatures, lower humidity than mid-summer storms and fewer very hot days. Many painters book out early for these seasons, so it pays to get quotes a few weeks ahead.
Can You Paint in Summer?
Yes, but timing matters. On hot days paint can dry too quickly, leaving lap marks and poor adhesion. Professional painters work around the sun, painting each side of the house when it is in shade and avoiding the hottest part of the afternoon.
What About Winter?
Interior painting is fine all year round. Exterior painting in winter is possible on dry, mild days, but cold mornings, dew and short days limit how long paint has to dry before evening moisture settles. Most acrylic exterior paints have a minimum application temperature printed on the tin.
Weather Conditions to Avoid
- Rain forecast within a few hours of painting
- Surfaces that are still wet from rain or morning dew
- Strong, gusty winds that blow dust onto wet paint
- Very hot surfaces in direct afternoon sun
- Very high humidity
Plan Ahead for the Best Result
Good preparation matters just as much as good weather. Washing, scraping, sanding, filling and priming before painting is what makes an exterior finish last. Learn more about our exterior house painting and roof painting services, or book a free quote before the busy season.
