I've seen Drylok mentioned in a few posts, and was wondering if it would stop my garage floor from sweating? The floor is almost 4 years old, and ever since it started getting warmer this spring, the floor sweats really bad whenever I open the overheads. It nerver did this before this year. Thanks

Nothing you put on the floor will stop it form sweating. The moisture is not coming from the concrete - it's coming from the air. The warm air flowing in through the doors hits the cold concrete and condenses. You really only have three options: 1) keep the doors closed to keep the warm moist air out; 2) keep the floor warm so the moisture doesn't condense (radiant floor heat), 3) live with it - it'll be summer soon.

I am currently using option 3) to deal with the condensation on my tools (I don't care about the floor beacuse it's not so smooth that it's slippery). I do the same every spring.

Well my biggest concern is my Mustang. i had it in a storage unit that "developed" a similar problem and the interior started to mildew. After threatening to beat the owner within an inch of his life (guaranteed dry) I got my deposit and a few months rent back. So I dont want the same thing to happen here. Guess I'll invest in a dehumidifier. Thanks

Any cool object will condense water out of the air when exposed to humid air, check out the bathroom mirror. A heater will probably work better than a dehumidifier. Don't open the overheads.

Guaranteed dry is only for rain or ground water. Nothing can be done to get rid of moisture in the air unless everything is hermetically sealed. There are salt caves here that are dry but then you have to deal with the salt. You were wrong to threaten the storage owner. Lucky he didn't just call the cops.

 

I wasnt wrong...I had a SIGNED lease that guaranteed NO moisture or water. No matter what the form.

 

What about something like a cold air return vents a couple just too equal out the temp swing,just like leaving the overhead open a crack but no critters get in.They could even be powered for better equalization of the temps.On in summer off in winter.

 

You need a heated and airconditioned space to keep off water vapor from the air.

 

DO NOT use Drylok on a floor. It will track every where and it will dust for a long time. It is made for stopping hydrostatic pressure in walls.
I have used sheets of cardboard under my cars for years and now that my shop is heated i have no condesation problems
