Hi Diane:

Dry-Lok is a compound that applies like paint and will seal poured concrete and cinder block walls for a time, and can be painted over, I believe. Its available at most home improvement centers and paint centers. There are other similar sealants.

But please keep in mind; this is only a temporary fix. If you have a problem with moisture coming through your cinderblock walls and if you don't solve the source of the hydrostatic pressure, it will simply be a matter of time before it returns. When we moved in to our present house, the entire basement had just recently had two coats of Dry-Lok applied. Within 2 years it was starting to bubble off in several locations.

Best wishes

Bruce M
