Forum, We have a 100 year old stucco house. At least part of the wall I can see in the garage looks like the cladding was applied as stucco with wire over wood board sheathing. I've found evidence of building paper on other sides of the house, but at least in the garage (and I'm assuming the bedroom above) it looks like there's no paper. On rainy days the water wicks through, and wets the framing. Some of the framing is ok, but some looks like it has definitely gotten some dry rot, though the house is clearly still standing.
I gather the ethos was just, pray the wall dries out before the next big rain, and, who cares about insulation, which if it was in there would just get wet and moldy. The outside of this wall is expansive, flat, and windowless.
Has anyone faced with this had positive results using an elastomeric paint to waterproof the stucco? The outside needs to be repainted regardless and I wondered if this would help, while not making the situation worse if intruding moisture then can't exit (there are no formal weep screeds, the water just runs down to the foundation knee wall).
