Can we just seal the walls?
Yes, seal the walls, but VENT them first. We believe all CMU, especially split face block, should be sealed to prevent water intrusion. All hard mortar types should also be sealed.
However - if you're working on a WET building, you don't want to SEAL trapped water in the walls. Imagine a 90ª day with sun beating down on a sealed wet wall with no exhaust path. Moisture vapor expands up 1600x. It has to go somewhere – so it leaks into the building, destroying trusses, drywall, crown molding and baseboards.
WickRight General Contracting's installation team uses siloxane-based sealants to manufacturer specs. We do not recommend water-based, "environmentally friendly" sealants. They do not work as well nor last as long as siloxane-based sealants.
Do masonry sealants work on Renaissance Stone?
It depends on who you ask. We say, not well enough to prevent moisture intrusion.
How WickRight General Contracting's team deals with cast concrete and Renaissance stone details...
If a detail
ISN'T structural – We remove it, flash behind it to divert water to the exterior of the building and away from other "stone", reinstall it AND attempt to seal it.
If a detail
IS
structural – We attempt to seal it, then design flashings, cornices or awnings to divert rain water from hitting it or sitting on it.
