The Basics of Exterior Masonry Paint Drying

Exterior masonry paint drying is the process of allowing a coat of paint to dry on the outside walls and surfaces of your home. It typically takes between two and four days for exterior masonry paint to dry completely, depending on factors such as temperature, humidity, and air flow. If it rains during this time period, the water will cause the newly-applied paint to become soft again and may need additional time to fully cure. The best way to ensure that your exterior masonry paint dries properly is by avoiding painting in wet or humid conditions, if possible.

Knowing the basics of exterior masonry paint drying is important to ensure a successful project. Now let’s look at what factors can affect the time it takes for this paint to dry.

Factors That Affect Drying Time

Temperature is one of the most important factors that affect drying time. If temperatures are too low, the paint will take longer to dry and may not even harden properly. On the other hand, if it’s too hot outside, the paint can dry out quickly but could also be prone to cracking or peeling over time. The ideal temperature for exterior masonry paint to dry correctly is between 10-25°C (50-77°F).

Humidity levels can also have an effect on how long it takes for your paint job to finish drying. High humidity slows down evaporation which means that moisture stays in the air longer and makes it harder for your paint job to completely set up and cure. Lower humidity levels allow more moisture in the air to evaporate faster, so your exterior masonry paints dry more quicker.

To get the maximum benefit from this process, you should try to open windows or use fans during painting projects whenever possible. However, avoid using them directly onto wet surfaces as this could cause streaking or unevenness in colour coverage instead of speeding up drying times as intended.

It’s important to understand the factors that affect drying time, such as temperature and humidity, so you can make an informed decision about when to start painting. Now let’s look at some tips for speeding up drying time.

Tips for Speeding Up Drying Time

It’s important to take the necessary steps to speed up the drying time of exterior masonry paint. Priming is one way to do this, as it helps create a barrier between the paint and any moisture that may be present in the wall. This can help reduce drying time significantly. Additionally, applying multiple thin coats instead of one thick coat will also help speed up drying time, as each layer won’t need to dry completely before another can be applied.

Another great tip for speeding up drying time is protecting your paint from the rain while it’s still wet. If you know there’s a chance of rain during or shortly after painting, make sure you cover your work with plastic sheeting or tarpaulin until it has dried completely. Doing so will prevent water droplets from settling on top of the wet paint and causing streaks or smudges when they dry out later on.

Finally, if you want your exterior masonry paint job done quickly without sacrificing quality, consider investing in an airless sprayer. Airless sprayers apply even layers at high pressure and significantly speed up overall application and drying times compared to traditional brush methods.


When it comes to exterior masonry paint, there is no one-size-fits-all answer to the question of how long does exterior masonry paint take to dry. Factors such as temperature, humidity and even rain can affect drying time significantly. However, with a few simple tips, you can speed up the process and ensure that your painted surfaces are ready for use in no time at all. So next time you ask yourself, “how long does exterior masonry paint take to dry?” remember these helpful hints and get painting!
