How Temperature and Humidity Affect Paint Application

April 25, 2020 12:00 am Published by Leave your thoughts

The elements are a major cause of exterior building wear and tear. Keeping the paint fresh helps protect your buildings and extend their lifespan, so long as you do it right—which is where DJC Enterprises Inc. comes in. We specialize in sandblasting and preparing tanks before we expertly paint them, resulting in the best possible paint application in Colorado.

What causes problems in paint application

  • Temperature: The temperature in which you apply paint can have a lasting effect on its dried quality. For example, if you apply paint in freezing temperatures, it may not dry until the weather has warmed up, which is a disaster. On the other hand, applying paint in extreme heat can also cause major issues. If you apply paint in hot weather, the surface may “skin,” or dry faster than the rest of the paint. If you’re thinking “at least it’s dry,” think again—that type of paint drying can cause bubbling and other big issues when the job is done.
  • Humidity: Humidity can also cause big problems in your paint job. Humidity leads to surfactant leaching, which can create brown or white discoloration within the paint. It also keeps water in the paint long past when it should be dried out, resulting in an uneven, bubbly or otherwise unattractive finish.
  • Drying time: If your paint doesn’t have enough time to dry or “cure,” the end result will be more unpleasant than you might realize. Humidity leads to not-completely-dry paint, which can be smeared or discolored if it’s touched before the official dry time. If the temperature is extreme in either direction, the paint might not dry at all, or it may take far longer to completely cure than it would in more favorable conditions.

Painting tips

  • Don’t paint in direct sunlight: If your industrial painting is scheduled to take place in direct sunlight during a hot day, you’re just asking for bubbling and other issues.
  • Don’t paint in the wind: Wind can also contribute to negative paint results, such as dirt and dust embedded in the paint, and paint that dries too quickly on the surface instead of drying fully throughout.
  • Know your paint: Latex-based paints can be applied to any dry surface, whereas oil-based paints need a completely dry, non-humid surface to adhere to.
  • Know your surface: If you are painting a wood surface, bear in mind that it can retain moisture and affect the drying time of your paint job.
