There’s Condensation on My Garage Floor — What’s Going On?


Homeowners want predictability and reliability from their garage floors. They want a system that can withstand the rigors of their daily life and not give them cause to worry. So when you’re walking into your garage to get into your car and start your morning commute, the last thing you want is to see condensation on your garage floor. If you find condensation on your garage floor, your natural reaction is to ask, “what’s going on?”


In most cases, condensation on your concrete garage floor isn’t cause for alarm, but you still want to understand the underlying causes can help ease any anxiety. Here are some of the possible reasons why there’s condensation on your garage floor.

When you have condensation on your garage floor, chances are it’s an issue with moisture levels in the air of your garage. When warm and moist air interacts with the cooler epoxy and polyaspartic floor coating, the air begins to cool when it comes into contact with the slab. Once that air reaches its dew point, it begins to condense on the surface of your concrete.


The dew point represents the temperature where the air becomes completely saturated with moisture. Therefore, when your concrete surface is cooler than the surrounding dew point, it will cause the warm air coming into contact with it to cool down significantly.

It Stems From Moisture Beneath the Slab

All moisture content does not come from the air — sometimes, it comes from the ground beneath your garage. While the two conditions may appear similar on the surface, moisture from the earth represents an entirely different issue for garage floor owners. If the soil beneath your concrete floor has a high moisture content, it can quickly absorb into the concrete. Conversely, if the air above the concrete is warmer and has less moisture, the concrete will try to get back into balance by pushing what’s absorbed to the surface so it can evaporate.

How Do I Protect My Garage Floor From Condensation?

Now that you know the potential causes of your wet and darker-looking garage floor, you want to know how to protect it. While there are steps you can take to adjust the temperature controls in your garage, one of the most surefire ways to account for condensation on your installation is to apply a sealer. While other companies may promise long-lasting sealants that protect your garage floor, Garage Kings offers our customers a proven epoxy and polyaspartic coating to address condensation issues.

Our epoxy and polyaspartic garage floor coatings will help prevent the moisture content beneath your garage from seeping up into your concrete and coming to the surface. Having one of our coatings can make it easier to clean up and mop away any moisture whenever it is present.


Additionally, you can improve air circulation across your garage floor to help better distribute the moisture content. Finally, by keeping your garage’s humidity levels in check   — late spring and throughout the summer months — you can make great strides in preventing the phenomenon in the first place.
