What Is the Ideal Temperature and Humidity for Exterior Painting in Woodstock?

June 19, 2023

Summer makes an excellent time to paint your home’s exterior. But did you know that the temperature and humidity can affect the painting process? So, what is the ideal temperature and humidity for exterior painting?

Keep reading to learn what Green Summit Contracting, Woodstock’s exterior painters, suggest as the best weather for painting.

How Weather Affects Painting

How do temperature and humidity affect the quality of a paint job?

Temperature

A high temperature provides the minor benefit of a quick dry time, especially when the paint is in direct sunlight. However, this benefit also creates a disadvantage. Direct sunlight and high heat reduce the life span of your paint and cause it to crack or peel much faster than normal.

If you paint during high heat, you reduce your paint’s lifespan before even starting!

Humidity

High humidity levels can prevent the paint from drying correctly, and you might notice drips. It can also cause mold or mildew to grow on the paint. About 75% of a paint’s durability problems occur from poor adhesion during the application process.

What Happens With Improper Exterior Painting

To fully understand the ideal temperature and humidity for exterior painting, you should know what happens when a painting project goes wrong. The biggest loss stems from time and money. Without the ideal temperature and humidity, your paint won’t adhere or will quickly bubble, blister, or peel.

The Ideal Conditions

Once you know the ideal conditioners, you can confirm the quality of any painter you hire. If they believe they can paint when the conditions aren’t beneficial, request a second opinion.

Temperature

The best time to paint is when the temperature remains between 50 and 70 degrees. Expert painters consider how direct sunlight affects the paint temperature and don’t just rely on the ambient outside temperature.

What does this mean for Woodstock, GA? The average high reaches above 70 degrees from April through October. Painters have ideal conditioners in November through March or during the early hours of the day before the sun rises high during summer.

Humidity

The ideal humidity for painting ranges between 40% and 70%. Fortunately, in Woodstock, the average humidity only climbs higher in July, August, and September. Humidity rarely drops below the ideal threshold.

Types of Paint

Painters typically use either oil-based or water-based paint for your home’s exterior: 

  • Oil-based: This paint holds up better to high humidity and should be your painter’s first choice. Oil-based paint provides more durability and resists mold and mildew growth.
  • Water-based: The only water-based paint resistant to humidity is 100% acrylic latex. While not as durable as its oil-based counterpart, it handles humidity well and offers some protection against staining, mold, and mildew.
