Why Does My Garage Floor Sweat

Hi catherine there are two possibilities that can cause your garage floor to be damp.

Why does my garage floor sweat.

Condensation occurs when excessive water vapor in the atmosphere comes into contact with a cold surface. Why garage floors sweat before you stop the floor from sweating you have to investigate as to what s causing it. The most common is condensation aka sweating garage floor. When relatively warm moist air comes in contact with a very cool concrete slab the cold temperature of the concrete will cause the air that comes in contact with it to cool.

When warm humid air comes in contact with a cold concrete slab water vapor in the air can condense on the surface of the concrete in the same way that a glass with ice sweats in summer. For many homeowners the reason for a slick garage floor is condensation. So one of the most effective ways to combat the issue is to install a dehumidifier in the garage. Running appliances in a cold garage without proper ventilation will also create excess moisture in the air.

Garage condensation is particularly common in the winter time in regions where temperatures. Having this running in the garage will pull much of the moisture out of the air allowing two things to take place. This usually happens more in the spring and early summer since the ground temperature is still low and the air is warm and humid. A sweating concrete floor can be a real nuisance that can create a slippery surface and make the floor damp.

Excess condensation can also be caused by improper roof drainage that causes leaks in your garage. There are a couple of reasons why your garage floor may be getting wet. When warm humid air from outside comes into contact with the cold concrete the air rapidly cools and condenses on the surface causing the wetness. For most floors condensation is the main reason for the sweating especially in warm weather.

Another very common source of condensation is rainwater and melting snow from cars parked in garages.
