Concrete sealer

In my experience concrete 'sweating' is more the cold concrete drawing moisture from the air, not coming out of the slab. Sealing it probably wouldn't change that, and might be slippery unless you add some grit. I have epoxied floors, but they need to be fully cured and very clean and dry or it won't adhere well. It will stop it from absorbing moisture, so it can be dried quicker with a little heat and circulation. Just keeping a fan circulating in there might solve your problem.
