How Does Florida’s Humidity Affect My New Paint Job?

Humidity does affect how your new paint job dries. It’s best for your new paint to dry smoothly, so any moisture in the air can be really problematic.

Mold Growth

Humidity prevents surfaces from drying quickly, and this includes painted surfaces. Most people clean their walls before painting but the humidity can mean that the walls are still damp when you start painting. This has the potential to lead to mold growing in between the wall and the new paint job, which will eventually grow through the new layer of paint. 

Slow Drying

Your paint will dry eventually, so why is it a problem if it dries slowly? For paint to dry, the water component of the paint needs to evaporate faster than the solvents. When it’s humid, the water evaporates slowly, leaving a thick, gel texture and layer on the paint. Then, when it becomes less humid again, this consistency will eventually dry and leave behind a wavy consistency due to not being set correctly. All in all, you’ll get a paint job that just doesn’t look great.


Paint drying slowly might lead to some imperfections. This could include issues with bumps in your paint, blisters, and even lifting, cracking, or discoloration.

This has the possibility of potentially getting worse depending on the quality of the paint used so always ensure that the painters you hire are using high-quality paint. Also, oil-based paints and latex and acrylic paints have different ambient temperatures that they dry best at—which means that humidity can impact when and how your paint actually dries.


There might be bumps or imperfections in your paint when it dries, but you also might notice an odd texture to it since the water in the paint will be struggling to evaporate. When it dries, you can actually see a waxy sort of texture, which definitely isn’t what you want after painting your entire home.


The moisture on the wood in wooden houses can cause it to swell. If you don’t have the expertise and put on a coat of paint incorrectly, the wood could swell. This means that when the humidity falls, you’ll likely notice cracks or chips in your wood.
