Tips for Exterior Painting in Delaware 

• Know the Best Time of Year to Paint

In central Ohio, the best time for exterior painting is between May and October. This is when temperatures are steady, the air is drier, and there are fewer surprise weather changes.

Most paints work best when the temperature is between 50°F and 85°F. If it’s too cold, paint won’t dry properly. If it’s too hot, it might dry too fast and crack later on.

Always check the weather forecast before starting your project. You’ll want at least two to three dry days—that means no rain, and low humidity. This gives the paint time to stick and cure properly.

• Spring: Get a Head Start with Preparation

Spring is an ideal time to prepare your home for painting. The weather is mild, and it’s the perfect time to inspect for any winter damage.

Focus on these steps:

• Power wash to remove dirt and mildew

• Scrape peeling paint

• Sand rough areas

• Caulk cracks

• Repair damaged trim or siding

Completing this task early allows you to start painting as soon as the weather improves.

• Summer: Best Time for Full Paint Jobs

Summer is a popular time for exterior painting in Delaware, thanks to its longer days and dry weather. However, high heat can cause paint to dry too fast, leading to bubbling or fading. To avoid this, paint in the morning or late afternoon and stick to shaded areas. When using a sprayer, be mindful of the wind to prevent overspray on windows or plants.

• Fall: Paint Early and Finish Fast

Early fall can work for exterior painting, but you’ll need to plan ahead. In Ohio, temperatures drop quickly—especially at night. If you're painting in the fall:

• Start in September or early October

• Make sure daily highs stay above 50°F

• Paint early enough in the day for it to dry before sunset

Morning humidity and evening dew can affect the finish. Waiting too late in the season may leave you with a paint job that won’t last through winter.

• Winter: Rarely Ideal for Painting

In Delaware County, winter painting isn't familiar. Between snow, freezing temps, and ice, it’s hard to find a good window for outdoor work.

But if there’s a short warm spell—like a few days above 50°F—you might be able to handle minor touch-ups. Just make sure:

• The surface is 100% dry

• There’s no snow or salt on the walls or trim

• You use cold-weather paint if available

Still, most painters avoid exterior work in winter and focus on interior projects or planning future jobs instead.

• Choose the Right Paint for Each Season

Not all paint is made for every season. If you're painting in spring or fall, consider using low-temperature paint, which is designed to cure properly even when the outside temperature is cooler—some of these work down to 35°F.

During summer, use paint that has UV protection to prevent fading. In humid months, mildew-resistant paints are a wise choice, especially when painting shady areas or those near plants.

Also, check if your chosen paint is self-priming or if you’ll need a separate primer coat. For older homes with wood siding, always use a quality primer for better grip and protection.

• Plan Around Delaware County’s Unique Weather Patterns

Ohio weather can be unpredictable. One week it's sunny, and the next there could be thunderstorms. If you’re planning a big paint project, always give yourself a few extra days in case the weather changes your schedule.

If it rained recently, wait 24–48 hours before painting—especially if you’re painting wood. Even if it feels dry, moisture can stay inside the material and cause peeling later.

Check real-time humidity and wind levels. High humidity slows drying time, and strong winds can affect spray tools or blow dust onto wet paint.

By staying flexible and watching the weather, you’ll have a much smoother painting process and longer-lasting results.

Summary!

Each season in Delaware County brings different challenges for painting the outside of your home. Spring is great for prep, summer is best for full projects, fall is good if you work quickly, and winter is usually best for planning.

The key to a lasting paint job is timing, proper prep, and using the right paint for the season. By thinking ahead and paying attention to Ohio's weather, you’ll get results that look better and last longer.
