The best temperature for exterior painting

The temperature at which you paint will have a big impact on the surface in general, it will determine factors like how well the paint adheres to the surface, how quickly it dries, and how durable it will be.

The ideal temperature range and painting season for painting with Sherwin-Williams exterior paints is between 40 degrees Fahrenheit (4.5°C) and 80 degrees Fahrenheit (27°C).

If you paint outside within the range of the ideal temperature, the paint sticks to surfaces better and dries faster, giving it maximum durability and lifespan.

It’s important to remember that certain exterior paint could have different specifications for surface temperatures, therefore, for exact specifications, always check the label of the product.

Once you’ve completed the painting process, resist the urge to rush the curing process, while paint may feel dry to the touch, it takes time for it to fully cure and harden.

Also, avoid exposing freshly painted surfaces to excessive moisture, abrasion, or extreme temperatures until the paint has cured completely according to the instructions of the paint manufacturers.

Cold temperature painting

The longer working hours that cold-temperature painting provides are among its most important advantages. Cold weather delays the drying process, unlike hot and humid circumstances that might cause paint to dry quickly.

We’ve all encountered the difficulties of painting in the blazing heat or warmer temperatures, like experiencing exhaustion and even risking the possibility of heatstroke.

Painting in colder weather takes care of these issues, it’s easier to stay relaxed and focused while painting in milder weather, which makes it more fun. You may completely concentrate on your artistic vision without having to worry about hydrating frequently or prevent getting too hot.

Cold weather tends to send insects and pests prompt to seek shelter elsewhere because due to the cold weather, there won’t be as many bothersome insects flying over your painting area, and there is less danger of them ending up in your paint.

On cold summer days, annoying flies, mosquitoes, and other insects won’t unintentionally end up on your surfaces, so in cold weather, you can focus on your painting without the added distraction of worrying about flies and other pests.

You can produce a faultless finish that rivals the work of seasoned professional exterior painters with the right paint handling and technique, your surface has a sense of precision and skill thanks to the easiness of paint application in cold weather.

Surprisingly, certain paints even work better when it is cooler outside. Some low-temperature paints are intentionally created to function well at low temperatures, these specialized paints contain additives that enhance their adhesion and cure effectively in cold temperatures.

Hot temperature painting

Painting in hot temperatures has its own set of challenges and considerations, but it also offers certain benefits.

The quicker drying time is one of the important advantages of painting at high surface temperatures, the high air temperature aids in the evaporation of paint’s moisture, hastening the drying process.

The high surface temperature may also be helpful if you have a limited amount of time or need to apply several coats, which might be harder at lower temperatures.

The flow and smoothness of the paint may be improved by the higher surface temperature, facilitating application and resulting in smoother coverage.

When exterior painting occurs at low temperatures, paint spreads more easily, lowering the possibility of the noticeable brush or roller markings and producing a more even and smooth surface.

The paint may also adhere to the substrate more effectively thanks to the heat, this is especially useful for porous surfaces like wood or concrete because the paint will penetrate deeper, resulting in better coverage and durability.

Hot weather speeds up paint drying, but it also increases the risk of paint drying out too soon, rapid drying might result in lap markings, especially when using dark colors.

Paint may become less viscous at high temperatures, this makes it challenging to retain control and produce a smooth finish since it can cause excessive amounts of paint to go to waste.

To avoid this, greater effort and technique might be needed, such as painting in smaller parts and applying thinner coats, painting at hot temperatures has some benefits, such as a quicker drying period and better paint penetration.

However, it’s important to be aware of the potential drawbacks and difficulties related to painting in hot weather, you can still produce outstanding outcomes with careful planning, preparation, and a conscious approach.

There are several paint manufacturers and various types of paint that can be used for exterior painting, your choice will be determined by your taste, but the best ones are latex paint and oil-based paint.

Latex paint

While there are various options available, latex paint stands out as a top choice for many homeowners and professional exterior painters. With its exceptional durability, versatility, and ease of use, latex paint has become the go-to solution for exterior painting projects.

Compared to other types of paint, latex paint dries more quickly, enabling you to apply more coats in less time.

A smoother and more professional finish is also achieved as a result of the rapid drying time, which reduces the possibility of debris, insects, or other particles becoming caught in the wet paint.

Since latex paint is water-based rather than oil-based, it has a milder odor, which makes it more enjoyable to use, especially in outdoor settings where ventilation may be restricted.

Oil-based paint

For years, oil-based paint has been popular due to its remarkable attributes and classic beauty.

Exterior surfaces are frequently exposed to severe weather, such as rain, sun, wind, and changing temperatures. Oil-based paint’s unmatched longevity guarantees that your outside surfaces are kept safe year after year.

They offer a rich, shiny finish that highlights your property’s architectural details, it also provides a glitter-like shine, giving any exterior surface an attractive and refined appearance that can improve its visual appeal.

Should I consider humidity?

Understanding and considering humidity levels can make a significant difference in the success and longevity of your paint job.

In general, a relative humidity range of 40% to 70% is considered normal. However, this can vary based on the type of paint you’re using.

High humidity levels can hinder the evaporation of water in water-based paints, causing them to dry more slowly. On the other hand, low humidity can lead to rapid evaporation, which might result in a compromised finish.

By paying attention to the weather conditions, using the right paint for the job, and working during recommended humidity levels, you can ensure a successful and long-lasting painting.

Tips for cold weather painting

Protect painted surfaces. Whenyou’re done painting, take precautions to shield the freshly painted surface from snow or moisture. To avoid any potential harm, cover or shield the area until it is totally dried.

Avoid direct sunlight. In cold temperatures, painting in direct sunlight might cause paint to dry too quickly, which could result in cracking and adhesion problems, try to work in the shade or during periods of less intense sunlight.

Prepare the surface. Before painting, thoroughly clean the surface and make any necessary repairs to any cracks, holes, or other damage, before applying the paint, make sure the surface is in good shape, as cold weather can make the existing damage worse.

Cold weather painting vs hot weather painting

Hot weather painting has several advantages, but exterior painting in colder temperatures is considered better because it offers greater paint adherence and lowers the danger of heat-related issues, even though painting in lower temperatures may provide quicker drying times and increased paint flow.

A durable and resilient paint job depends on achieving a strong bond between the paint and the surface.

Therefore, to ensure a successful and long-lasting exterior painting project, I will recommend painting in colder weather or cold temperatures especially when using dark colors.

How cold is too cold to paint outside Sherwin-Williams?

When the ambient temperature drops to 38 degrees Fahrenheit, it is considered too cold to paint outside because the cold temperature might not allow it to cure properly.

At what temperature should you not paint outside?

You should not paint outside at any temperature lower than 38 degrees Fahrenheit or any temperature higher than 90 degrees Fahrenheit.

What happens if you paint below 50 degrees?

Painting below 50 degrees is totally okay, although there is a higher chance of improper drying which can affect the physical appearance of the surface.


Understanding the impact of temperature on Sherwin Williams’s exterior paint is crucial for achieving a successful and long-lasting painting. By following the procedures above, you can ensure optimal exterior paint performance and a beautiful finish.

Remember, temperature matters when painting with good exterior paint, so choose wisely and enjoy the results that stand the test of time.
