What is the Ideal Humidity for Painting?
The best, most ideal weather for painting your home’s interior is between 40% and 50% humidity. However, for residents or businesses in Grand Rapids, Michigan, this can be a bit of a problem. With an average humidity of 71%, it isn’t a perfect environment for painting. Many cities in West Michigan suffer from high humidity due to their close proximity to Lake Michigan.
Fortunately, it is still possible to paint well in humidity ranging from 50% to 80%. Be warned, though, that humidity below 40% or above 80% means that painting should wait for another day.
What Happens to Paint in High Humidity?
When humidity is high, there is a lot of moisture in the air. This could greatly affect indoor painting and the result of your work.
High humidity has the following effects on interior painting:
- Longer Drying Time - Due to the moisture in the air, paint can take hours longer to dry, prolonging your project if adding multiple coats of paint
- Peeling or Fading - The paint could peel, buckle, or blister and cause the color to fade due to high humidity
- Potential Condensation Problems - In some homes or offices, condensation could form on the walls, causing paint to appear abnormal
Taking the necessary extra steps and precautions when painting in high humidity can avoid these issues, though.
How to Paint in High Humidity
It is completely possible to paint in high humidity. There are just some extra steps and considerations to ensure your paint goes on smoothly and dries in a timely fashion.
At VanDerKolk Painting, we’ve become experts at painting interiors in the humid weather of Grand Rapids. So, we’re sharing our tips that guarantee a perfect paint project.
Choose the Proper Paint
Some paints do better in high humid areas than others. When painting in high humidity, it’s best to choose either a water-based paint such as acrylic or latex. These paints are not as heavy as oil-based paint and will dry in an appropriate amount of time, even with the humidity.
Make sure to paint thin layers of water-based paint in high humidity so it dries faster. It’s also important to remember to wait until the paint is dry before adding another coat. Normally, water-based paint has a
recoat dry time of four hours. However, this may be longer in high humidity. Along with water-based paint, you may choose a solvent-based finish when painting in high humidity.
Increase Airflow
Adding extra air circulation methods will help paint dry faster in high humidity. If possible, open a window in the room and set up fans to keep the air moving. It’s even better to have a ceiling fan that can move air throughout the room.
Use a Dehumidifier
One of the most useful tools when painting in high humidity is a dehumidifier. This will take the moisture out of the air, allowing the paint to dry faster and avoid peeling or buckling.
If you use a dehumidifier, turn it on in the room a few hours before you begin painting. This will remove most of the moisture and better prepare the area for painting.
Paint in the Morning
The best time for interior house painting in high humidity is in the morning - but not first thing. Overnight, moisture may condense and become heavier without the sun absorbing water droplets. It is best to wait until the sun has risen and been up for an hour or two before painting.
Painting in the morning also gives you more time to let the paint dry properly before adding additional coats to it.
How Do You Dry Paint in Humid Weather?
Even in highly humid weather, the paint will dry on its own. However, it will take longer than expected.
Some ways to decrease the dry time of your paint in high humidity are to:
- Use a dehumidifier
- Increase air circulation with fans and by opening windows
- Using a hair dryer on specific parts of the wall
Remember, it’s important to be patient and not add more coats of paint before the initial coat is fully dry. This could cause bubbling and uneven coloring.
Can Paint Dry in 80% Humidity?
Painting your home with 80% or more humidity is not recommended. While the paint will take longer to dry, other risks, such as peeling, buckling, and splotchy color, should be considered.
The best humidity for interior painting is 40% to 50%, but up to 80% is also acceptable. If painting in humidity above 50%, use additional methods and equipment such as fans, dehumidifiers, and water-based paint for the best results.
