Fixing an airsealing miscommunication
I’m working on new construction in a mixed humid environment. I specified tape be placed on all OSB seams, but when I visited the construction site I found that the seams had not been taped. The housewrap is already on, and I’d really rather not set the project back by removing the housewrap to tape everything.
My question is whether there is a good (or at least workable) alternative to airseal the OSB joints from the inside of the house? I realize this will not be as effective (or likely as time efficient) than if it had been done right to begin with, but I’m essentially trying to mitigate the problem.
I imagine that I could tape from the backside of the OSB (although from what I read I’d likely have to use primer to get the tape to stick), but that seems like it would be pretty fussy. Would it be kosher to use acoustic sealant, mastic, caulk, etc. on the joints from the inside, or would that prove problematic? The last thing that I want to do is inadvertently create durability issues.
For reference, I’m planning on using board and batten siding, with dense pack cellulose insulation in the walls. The walls are 2×6 framing, 24″ on center.
Thanks for any input,
