I have almost 2 gallons off this stuff left over from the cash for clunkers days.
Will it be useful to treat a sweaty floor in my house garage? Not looking for a cure. If it slows it down (vapor transmission) I'll be happy.

Quote from another thread......

Concrete: (use in basements to slow or prevent Radon leakage)

Concrete treated with a sodium silicate solution helps to significantly reduce porosity in most masonry products such as concrete, stucco, plasters. A chemical reaction occurs with the excess Ca(OH)2 (portlandite) present in the concrete that permanently binds the silicates with the surface making them far more wearable and water repellent. It is generally advised to apply this treatment only after the initial cure has taken place (7 days or so depending on conditions). These coatings are known as silicate mineral paint.

Apparently sodium silicates are broken down over time by water. It may work for a few years, try a sample patch and see what happens over a couple of months.

Early version of the densifiers we use today.
Good at dust-proofing and stopping efflorescence but will definitely not stop water transmission.

I don't see why not, but are you sure the sweating is moisture coming up, and not condensation?

Almost 100% sure. I'm no expert but you cannot leave a plastic tote on the floor w/o lots (not a little but LOTS) of moisture dripping standing water.
cardboard boxes get ruined. My shop has none of these issues.
Because I made them use a vapor barrier.
We open the garage door daily or leave it cracked.
There are days in the Seattle area where when you open the door the moisture comes in fast and covers all the cold items in the shop or garage.
So I do understand what your asking.
