I removed the carpeting and drywall from one bedroom due to mold from a slow pipe burst. Now the mold is gone, the wall is repaired. I have a clean concrete slab floor. I have slightly painted the floor with a very watered down latex wall paint, just to see if it would adhere. I am looking at both your floor paint and the penetrating sealer. Is it too late to put the sealer on? Because I put the washed down paint on? I laid a towel down on one corner of the floor and it got musty. I think this is because moisture is slowly coming in the slab from outdoors. Would the penetrating sealer rectify this? Thank you for your help.

A critical point of the Penetrating Concrete Sealer is it needs to be applied to porous, clean, uncoated concrete so that it can penetrate into the concrete slab. If you got paint in the way (even watered down paint) then the penetrating sealer can't penetrate.If you get the paint off, you might be able to use the sealer, and it will help prevent moisture from coming up from under the concrete.
