Is There a Right Time To Paint a House’s Exterior?

Paint is fickle. Too much humidity, and it will dry too slowly. Too much (or too little) heat, and it will crack or peel.

Thankfully, there are widely accepted temperature and humidity ranges that are acceptable for painting: it can be as cool as 40 degrees or as hot as 85 or 90 degrees. Humidity-wise, you should aim for a day that’s humidity index is between 40% – 70%.

Why does it matter? Well, there are several reasons to keep track of all of these weather measurements.

Temperature is important when painting your house’s exterior. Both low and high temperatures can cause for chipping and peeling paint. This ultimately happens because paint applied in temperatures like these fails to bind together as it should.


Too much condensation can also present a series of issues when waiting for paint to dry. It can cause for paints to be very slow to dry. In some cases, high humidity may even lead to paint that leaves long, unsightly streaks. This, of course, is not a good scenario. You certainly don’t want your house’s exterior to be covered in obvious blemishes.

However, this isn’t the worst of the problems high humidity can cause. Humidity can also be responsible for paint that fades quickly or sticks to the surface poorly.

Other Things to Look Out For

  1. The Nightly Low – Don’t forget that the temperature still matters after you’ve laid down your brush. If you’re thinking that there’s a chance the temperature will dip below 40 overnight, consider waiting for a warmer night to come along.
  2. Temperature Fluctuations – Even if you’re expecting an 85-degree day and 40 degrees come night, you may want to consider re-scheduling your painter. Massive temperature fluctuations have the potential to cause problems with paint that’s in the process of drying.
  3. Work with a Professional Who Cares – If your painter doesn’t seem to care much for the idea of waiting for an ideal day to paint, they may not be the one to hire. After all, a day’s conditions really do matter. Keep in mind that there are some instances where specific kinds of paints can be utilized in different conditions, but no matter what, don’t forget that your painter should be putting your best interests first, and it should be obvious that they are doing so.
