Hello All,

We just completed our 2.5+ garage in March of this year, and for concrete, I chose an epoxy and had the contractor complete the application.

We are located on Long Island, NY...right on the water, and it tends to get rather humid.

Several times, I have walked into the garage after it has been closed up for the week (we only get out on weekends for the most part), and within a couple minutes, the entire floor of the garage is cover in water/moisture - akin to a beer bottle sweating. It obviously is not coming THROUGH the floor, as the paint is not pealing and I know the contractor put down a vapor barrier.

As best I can figure, the concrete is significantly cooler than the ambient temperature, and when the doors are opened up, the differences in air temperature cause moisture to form on the floor. With the epoxy on top of the concrete, the moisture as no where to go, and forms on the floor. Does this make sense?

Our garage is not air conditioned during the summer, only heated during the winter.

Is there a solution to this problem? Is something like RaceDeck the only solution, so I do not have to worry about boxes getting soaked?

 

Try a dehumidfier. Its been a very hot and humid summer. Or wait until the fall and determine if there is still moisture. I only think RaceDeck will hid the moisture.

 

Learn to live with it. A humidifier is no match for an open garage door. Maybe get some open type walking mats like you would put around a pool to keep you from slipping on your butt.

 

You may need to ventilate your garage. Sounds like it's buttoned up pretty tight. You would know if it was coming up from below because the hydrolic pressure will lift the epoxy right off the concrete.

 

Garage Guy,

I know it isn't coming up from below, as you mentioned. It all just settles on top of the epoxy. As far as ventilating...open up windows and doors during the day to allow for temperatures to equalize?
