We have a 1950's style brick ranch house that has parging on the
foundation as well as the lower levels of brick, below ground level.
We are planning on building a dry stack wall in the front of the house
to make level flower beds. Once we backfill the beds there will be
about 10-15" of un-parged brick that will be below the "new" ground
level (our property slopes away from the house on either side). I'm
going on the assumption I should parge the brick to keep it sealed,
right? But what do I use? Just some pre-mixed cement, or is there a
special product or "formula" I should use? Also, is there any
particular prep I need to promote adhesion? What about cure time?
Any other suggestions, tips, words of advice on the parging/skim coat
as well as the dry-stack wall would be most appreciated.
