Hi!
I talked to an old builder, you know the old-fashioned kind of combined builder and engineer who "knows everything."
He said I should mix a loose slurry with cement and water and add a few drops of dish soap to reduce surface tension, and then "paint" this on my newly built wall (masonry blocks and mortar) to reinforce it.
Rice or roses?
Worth it? It's been about a week since I finished the wall, and a little extra cement can never hurt, right?
