Hi, I offset and reconstructed a retaining wall against my house and, in doing so, I exposed more of the basement's (exterior) cinder block wall. The previosuly underground cinder block has tar coating (waterproofing) on it. My wife _hates_ how it looks. I think it would be awful to tar the rest of the wall. I know the existing tar will not come off without a sandblaster . Any suggestions on what might look nicer? I was hoping something like a white tar coating exists, just so it looks nice.
