subfloor OSB exposure
for the construction folks out there, what would you consider normal exposure levels for OSB subflooring? The subflooring has been left exposed for 5 months now due to delays and it’s showing quite a bit of flaking, discoloration, and raised edges. The brand is durastrand. According to the durastrand website Q&A they brush off any moisture issues as purely cosmetic and you should just sand them. Should I be concerned about long term issues? In at least one place where things were put on top of them, I saw some mildew/mold, probably small enough to be sanded off but still concerning.
