Epoxy Garage Floor Paint Keeps Moisture Out...And In.

Garage floor paint will certainly protect the concrete from any moisture in the air, but it do nothing against moisture that comes from underneath. Epoxy, by design, creates a seal that is nearly impenetrable by moisture of any kind. When oil drips onto the floor, this is a good thing because that means it will not get past the paint, so will not be absorbed by the concrete, and can therefore be sprayed off.
