Re: Coated OSB
Never heard of tar paper being touted as being self sealing . Besides the asphalt is used to provide moisture resistance of the paper substrate and isn't elastic enough to seal a pentration.
The coating on the panel is a weather resistant barrier -- not a weather proofing barrier , so , pentrations from fasteners is not a big deal. The fasteners are filling the hole they create.
Mr. Kirk --- well said about the difference between the types of contrators and the types and use of materials -- so true.
