Why is my garage floor so wet?
For many homeowners, the reason for a slick garage floor is condensation. Condensation occurs when moist air comes into contact with the cool concrete of the garage floor. Upon this meeting of two conflicting temperatures, the air begins to cool below the dew point, condensing on the concrete’s surface.
Why does my concrete garage floor get wet?
The most common is condensation — AKA sweating garage floor. When relatively warm and moist air comes in contact with a very cool concrete slab, the colder temperature of the concrete will cause the air that comes in contact with it to cool.
Why does my concrete look wet?

Why does my concrete have spots?
As the water evaporates to the surface and soaks into the cement that is an ingredient of concrete, it leaves behind darker spots where the cement contains more moisture. These will fade over time as the water eventually soaks into or evaporates out of the slab.
How do you fix blotchy concrete?
Cleansing — For mild discoloration, repeatedly flushing the hardened concrete surface with hot water, then scrubbing with a stiff brush, can reduce or remove discolored blotches. Acid treatment — If the discoloration is more severe, a mild acid solution of 1-3% muriatic acid to water can help remove the discoloration.
What is concrete mottling?
