I recently offset and reconstructed a retaining wall against my house, which exposed more of the basement's exterior cinder block wall. This previously underground cinder block has tar coating on it for waterproofing, and my wife and I hate how it looks. We don't really want to tar the rest of the wall, and I know the existing tar will not come off without a sandblaster. Any suggestions on what might look nicer? I'm hoping something like a white tar coating exists, just so it looks nice.
