Timing is everything when it comes to exterior painting, and getting it right can make a huge difference in how your home looks and how long that fresh coat will last. If you paint during the right season and under the right conditions, you’ll likely enjoy those vibrant colors and crisp lines for years to come (without needing to repaint anytime soon!).
Spring and fall are typically solid choices for exterior painting thanks to their milder temps, but weather isn’t always predictable, and not every “perfect day” on the calendar turns out to be ideal for paint. That’s why it’s smart to look beyond just the season and pay close attention to the forecast before diving into your next project.
Let’s take a look at which times of year are best for painting, what weather conditions to avoid, and how to make sure your paint job turns out smooth, durable, and built to last.
Which Seasons Are Best for Exterior Paint Projects?
Spring
Spring’s mild temperatures make it a good time to paint your exterior. Just keep an eye on the wind, rain, or severe weather in the forecast and make sure you have at least a few days before and after your project that won’t be rainy or too windy.
Fall
For many regions, fall is a great season to paint a home exterior. The weather is mild with less humidity, which helps the paint to dry evenly and thoroughly without issues.
How to Ensure You Get a Long-Lasting, High-Quality Finish for Your Home’s Exterior
How long paint lasts is directly related to the temperature and conditions at the time of its application, so there are a variety of factors to consider when planning your next exterior painting project.
Weather Conditions
Plan your paint project on a day that the weather is mild, dry, and there is no chance of rain. It’s crucial that your siding is fully dry before you start painting so the paint adheres. Make sure it hasn’t rained in a few days before you’re scheduled to begin your project.
When planning your exterior paint project, avoid windy days because wind can blow dirt and debris onto the wet paint, marring its appearance.
Dew can ruin a fresh coat of paint, so make sure the temperature is at least 5 degrees above the dew point so you don’t end up with a sticky mess.
Cloudy skies are beneficial when your exterior is being painted because it allows paint to dry at an optimal pace. While it’s not imperative to paint on a cloudy day, it’s a bonus if you can.
Temperature
The temperature plays a big role in how your paint dries and cures. Stay in the recommended range for the best possible finish.
- Not too hot – If you paint when it’s too hot outside, your paint will dry too quickly. It won’t adhere properly, which may leave you with a cracked, peeled, or blistered exterior.
- Not too cold – If it’s below 35 degrees Fahrenheit, the water in your water-based paint could freeze and prevent it from curing properly.
- Just right – The best temperature range for exterior painting is between 50 and 85 degrees Fahrenheit. (Although if you can paint when it is between 50 and 70 degrees, that’s even better!)
Humidity Level
High humidity doesn’t allow paint to dry fast enough. The ideal humidity level to paint your exterior should be between 40–70%.
Know Your Paint Type
The type of exterior paint that is used for your project will also factor into the best time to paint your home. Water-based acrylic latex paint (which is excellent for home exteriors) is negatively impacted by high humidity levels. Oil-based paint needs warmer temperatures to cure than water-based paint.
Time of Day
Painting your exterior at the right time of day will ensure it looks fabulous and lasts for years to come. When scheduling your exterior paint project, avoid painting too late in the day. Get started early so you have plenty of daylight hours to get the work done.
Follow the Shade
Direct sunlight can cause paint to dry too fast, leading to brush marks and uneven paint application. The solution? Follow the shade around your house as you paint throughout the day. This means since the sun rises in the east, paint on the west side in the morning. Paint on the east side in the afternoon to keep the sun from softening your crisp coat of paint, causing it to attract dust.
Understand the Difference Between Paint Drying and Curing
Drying
Paint may feel dry to the touch, but that doesn’t mean it is cured. When paint dries, the solvents in it evaporate, leaving the paint “feeling dry.”
Curing
For a paint job to last, it needs to “cure.” This means it achieves maximum hardness and durability. This takes 2–3 weeks for latex paint. Curing is a chemical process where pigments and binders fuse together creating a strong, durable, weather-resistant film. Temperature, humidity, and airflow affect curing time. So can the type of surface you’re painting.
For paint to cure properly, have your home painted on a day when weather is consistently mild and dry. Check the forecast a few days before and after your painting project begins to ensure it is dry throughout those days too. Make sure your paint has enough time to harden and fuse to your siding, attaining its full durability and strength long before rain is in the forecast.
