How Temperature and Humidity Affect Paint and Painting Application

While states that experience cooler climates need only worry about rain and wind for exterior painting projects, homeowners in Las Vegas must contend with temperature and humidity during both interior and exterior projects.


Each manufacturer will provide guidelines for use on paint containers. It is in your best interest to follow the instructions, as each paint formula is designed for use within specific temperature and humidity parameters. Take your time when purchasing paint, and make sure you are well informed on likely temperatures and humidity levels before you go shopping.

Temperature and Drying Paint



In order for paint to properly apply to the substrate (the surface that the paint is being applied to), it must be allowed to dry under suitable temperature and humidity levels. Too cold and the paint may not adhere, leaving you with paintwork that is patchy and unsightly.

Bumps and wrinkles occur when the paint is allowed to dry too rapidly. Think about cooking a thick steak in a microwave on high power in less than two minutes. You will find that the outside of the steak is hard and dehydrated, while the center of the steak remains raw. The same principle applies to rapidly dried paint. The surface dries before the center, resulting in bumps and wrinkles.

Humidity and Drying Paint


Painting wooden surfaces is also problematic in high humidity, as wood is porous and will absorb any excess moisture from the air. The added moisture will usually cause the paint to peel and bubble as it dries. It doesn’t matter how many coats you use, if you continue to apply paint in conditions with adverse humidity, the results will likely be the same.

Then there is the problem that low temperatures and high humidity present for exterior painting. Surface condensation can ruin a paint finish, and that is something you will want to avoid when carrying out large exterior painting projects.

Avoiding Problems

It is a good idea to monitor temperature and humidity levels during painting projects. However, you should also avoid painting during times of the day when adverse levels of temperature or humidity are likely to occur. You can also use website services, such as Weather and Climate, to help you predict the best times of the year for your project.

If you are carrying out a large project, using different types of paint, planning becomes much more difficult. Rather than taking a gamble, it makes more sense to seek the help and expertise of professionals.
