ripping up old carpet::Floors are very difficult to paint properly, and the failures tend on the high side.
With that being said, it appears that you are serious about painting.
As stated, a clean dry floor is required.
Duct tape all around the plastic and stick on floor.
The duct tape acts as a air seal.
Leave this on floor for minimum 24 hours.
Pull off plastic and examine concrete.
If it has changed color relative to the surronding floor, dont paint.
There is no commercial paint available that will stop hydrostatic pressure for floors.
Very unpleasant and not easy to repair.
Latex floor coatings are very nice, and have come a long way.
These will allow some moisture to migrate out of the coating, better than oil.
Muratic acid is the most effective washes, but can be deadly in an inclosed enviroment.
Again, acid filter, as the acid will compromise a paint filter in seconds.
There is special charcole for acid.
Also, remeber to remove any electronics from the basement, as the acid vapor is very caustic and will degrade circuit boards, and any exposed metal.
There are some etchers that are not as toxic, but are more expensive, and work much more slowly.
