Re: Condinsation on floor
Where do you live? How hot does it get? How humid does it get? What is the temperature of the floor in the garage, compared to the ambient temperature?

Dehumidifier but if your up in the northeast right now good luck. Concrete is colder than the moist hot air perfect recipie for wet floor.

Re: Condinsation on floor
I don't think there is a lot you can do really, but keeping the place reasonably air tight will eventually condense much of the water out of the atmosphere. Unfortunately you still have to open doors and suchforth which lets new damp air in.
A dehumidifier would help, but as above, as soon as you open a door or window you have fresh wet air entering.

My parents garage had a similar problem. We found that if we removed the attic access cover (and installed a screen) the problem went away.

Condensation happens when warm moist air contacts a cooler floor. The air temperature at the floor level drops below the dew point of the air and moisture in the air condenses.
There are a few things that can help, not all are necessary:
Leave the doors open and let the floor warm up. It will have condensation for a while and then it will subside.
Run a dehumidifier (I do this in garage #2)..
Air condition the garage (I do this in garage #1).
Run ceiling fans; air circulation will reduce or eliminate condensation (I do this, too, in both garages).

I have this problem in my shop primarily in the winter though it is the same phenomenon -- warm moist air on a cooler floor. Here in the PNW, we frequently get the "pineapple express" which are warm, heavily moisture-laden fronts that comes through repeatedly in the winter. This humid air condenses on the floor leaving it wet. You know it's condensation when it is limited to the floor surface.
Two things have completely cured this for me: first is a ceiling fan with air movement in the downward direction during the winter. The other is a humidistat-actuated exhaust fan that I built out of 6 inch round duct with an in-line duct fan. The intake end of the duct is about 1 inch off of the floor. It then exhausts about 3 feet up and through the exterior wall. Works great!
I set the humidistat after some trial and error and got it dialed-in in a week. When used in tandem with the ceiling fan, the floor stays dry, dry, dry.

The problem with concrete floor is they tend to stay cold, even when the above ground temperature is warm, which is why they have condensation in the first place.
Our house in Asia is built with concrete and tiled floors, specifically because it will stay (relatively) cool even when the room air temp is 35C (95f)
Back in the UK people always said you need plenty of ventilation to get condensation out of the garage. It might work, but the garage is then freezing cold, which isn't very conducive to working in it.
