I recently offset and reconstructed a retaining wall against the
house, and it exposed more of the basement's (exterior) cinder block.
The previosuly underground cinder block has tar coating
(waterproofing) on it. The wife _hates_ how it looks. I think it
would be awful to tar the rest of the wall, and I doubt the existing
tar will come off without a sandblaster (or a pressure washer so
strong that it would damage the cinder block). Any suggestions on
what might look nicer?
There is an exterior cement wall paint that you could even out the
I recently had it done in a situation similar to yours. Paid but
should have done the job myself.
First the contractor went over all the small foundation cracks with
silicone and then painted over.
It looks good and corrected several spots I had repaired where color
was never the same as the rest of the foundation and where some of the
original cement finish flaked off exposing tar coating. All now a
uniform white coating.
May get posted twice as Google Groups post I made earlier did not show up.
I recently had my foundation coated with a white acrylic sealer type
paint to cover up blemishes like this or crack repairs I had made over
the years that did not blend in.
First the contractor covered any cracks with silicone caulk and then
painted the whole thing. Now the foundation is a uniform white and
looks good. I could have/should have done it myself.
Thanks for all replies!

I also suspect this is bad condition because wind-driven rain can hit
top (unsealed) section of cinder blocks, be absorbed, and have nowhere
to go but inside.
Any product recommendations appreciated!!
I can't see how far that wall extends, but I'd consider putting
one of the stone veneer products on the whole thing. The only
obvious issues are if the thinset or whatever is used will bond
to the coating that is there and the cost.
The tarred area of the wall looks to be mostly parged, as it would be when
intended to be buried. I had a small area about 6" tall that was exposed and
tarred, across a 20 foot wall and I managed to use a wide masonry chisel to
chip off the parging. It was slow and difficult but I managed to remove it
all and then recoat it with a new color-matched parge to blend in with the
bricks. Depending on how well it was applied sometimes the parge will come
off in sheets, sometimes you have to chip away at the whole area.
