Detached garage floor wet, epoxy or not?

[Hivolts]

All,
Just demo'd 3 car detached garage. Roughly 800 sq ft here in SC. Garage was built in 1986 and the floor has never had a coating on it yet is still in very good shape.

Question is. During high humidity, probably 95% and up, especially rainy days. The floor gets wet through the concrete. Not wet enough to shop Vac or use a towel but moist, changes color type moist. Any other time concrete is dry with no issues. Can epoxy still be a choice on my install?

Thanks

You have to determine if the wetness is condensation on the floor of moisture coming from below. With the building now gone I'm not sure how you would do this. In a building you would do this by taping a sheet of visqueen over an area and checking when the problem happens. If the area under the visqueen stays dry then its condensation, if its wet then it is coming up from below.

no neat sig line

Not a complete demo. Just took down all drywall and ceiling drywall to replace.

I'll leave some plastic and tape on an area I know gets wet during high humidity. If that area is stays dry I'd assume it's condensation.

If wet under I'll assume its coming from below.

If coming from below epoxy wouldn't be an option?
Thanks

At that point you would have to determine how bad it is using a moisture test kit.
If too much moisture, then you would have to pass.

If I have a customer with visible moisture, I would suggest they pass on it. There are other options, breathable sealers, polishing, etc...

It may be that you have condensation forming on the surface so an inexpensive wall fan to ventilate may solve this problem. Once you determine it's not coming up from the slab then you can proceed once the floor has been tested with a moisture test kit which measures them moisture level emanating from the floor. We carry these if needed.

An alternate would be ventilated garage tiles as offered by us, or other vendors on this site.
