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 previously underground cinder block has tar coating (damp/waterproofing) on it. My wife _hates_ how it looks. It would be awful to apply tar to the rest of the above-ground wall just for the sake of consistency. 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.
