According to The Paint Quarterly Institute, most latex paints should not be applied when the air temperature is below 35°F to 50°F. The ideal temperature for outdoor painting varies by climate and region, but is generally within a specific range.
A temperature range of 50°F (10°C) to 85°F (29°C) is considered optimal for exterior painting projects.
Within this range, the paint can adhere properly to the surface, dry at an appropriate rate and provide a smooth finish and uniform. However, remember that humidity levels also play an important role in the painting process.For example, in Sacramento, where the climate is characterized by hot, dry summers, it is advisable to paint during the milder seasons, when temperatures are more moderate, usually in spring or fall. In addition, taking into account relative humidity, the goal of achieving levels between 40 and 70% guarantees optimal painting conditions and helps prevent problems such as long drying time or poor adhesion. By considering Sacramento's specific temperature and humidity factors, you can plan your exterior painting projects effectively and achieve exceptional results. As most people know, painting in winter and in the colder months is totally forbidden. Once the temperature drops too low, we have to postpone our exterior painting projects until next spring or summer.
So now, as we enjoy the warm summer weather, a question comes up. Can it also be too hot to paint exteriors? In other words, what's the right temperature for painting outside?It is strongly recommended not to paint below 50 degrees Fahrenheit if you are using latex-based paint. If you use oil-based paint, you can get away with 40 degrees Fahrenheit, but anything below that temperature is too cold. Why is temperature important when it comes to outdoor painting? If it's too cold, the paint may not adhere properly and cause unwanted cracking and peeling.
Lower temperatures mean slower drying and longer cure times, usually of 24 hours. In addition, watch for peeling or the inability to adhere to the coating or surfaces. Latex paints work best when applied at temperatures between 50° and 85° Fahrenheit. However, if you decide to use oil-based paint, its ideal range is a little wider than 40° to 90° Fahrenheit.
If you dare to paint in cold weather, make sure you don't let the surface or air temperature drop below 35 degrees for at least 36 hours after application. The paint doesn't cure or process properly and you can end up with unsightly bubbles and bumps in the paint when spring comes. For best results, we recommend not painting if the temperature drops below 50 degrees Fahrenheit. When painting a house, most professionals begin the process by following the sun's shade around the house.
When it gets colder, it's best to postpone any exterior painting project until the warmer months arrive.

Likewise, cooler temperatures can hinder the drying process and increase the time needed for paint to fully dry and cure. The truth is that the best time to undertake a painting project is when the temperature is moderate and with very little wind.
Latex acrylic paint, also known as water-based paint, is a versatile and widely used option for outdoor projects. But these high temperatures raise a fairly common question: How much heat is too hot to paint the outside of your house? While specific temperature ranges may vary depending on factors such as humidity and type of paint, it's generally a good idea to avoid painting in excessively hot climates. But how do you know when you shouldn't paint outdoors? Understanding the circumstances that may hinder the quality of your work is important for achieving a flawless finish. Under ideal outdoor conditions, oil-based paint can take six to eight hours to dry to the touch, and curing can take up to seven days or more.
Latex paint is also more environmentally friendly, as it has lower levels of volatile organic compounds (VOCs) compared to oil-based paints. A common mistake is to paint when the maximum temperature during the day is over 60°F and nighttime temperatures are much cooler because dew forms on almost everything as soon as the sun goes down. When deciding when not to paint outdoors, time is key to achieving results that will satisfy you.
