Ice & Water Shield over OSB
I’m going to be putting Ice+Water shield over a barn I’m insulating on the outside. The OSB is gapped (1/8″). Will the gaps pose a problem for the water shield? These gaps will be visible on the interior for at least a year. Should I use a flashing tape first (like 3M’s All Weather Flashing) on the seams first, before covering the siding? Grace (and other mfg’s) of the peel and stick warn you not to have it exposed to living spaces. I’m also concerned that the Ice+Water will not be tough enough to span the largest of the 1/8″ gaps.
