I have a stone mortar foundation with concrete floor (not floating). The walls and floor were painted/coated with many layers of thick paint or sealer by the previous owners. The basement does not leak or flood, but the floors and walls show signs of moisture. The surface is stained and flaking off because of the moisture. If something is placed directly on the floor, a significant amount of water collects under it in a 24 hour period despite the many coats. The thick coats of paint/sealer, dust and dirt make it almost impossible to clean and prep properly. Is there something that I can seal the surfaces with that doesn't require the removal of the old paint? I'd like to use something that sticks well, blocks moisture, prevents further flaking, and has a uniform look. Drylok doesn't seem to do the trick. Any suggestions w=or advice welcomed.
