I am replacing subfloor in a 6x18 addition. How do I lay out the 4x8 TG OSB? The joists are 12” on center and run parallel to the 20’ length. I’m not sure if 6x4 sections side by side perpendicular to the joists are OK without staggering? But there’s only 6 feet to stagger with. Unsure how to proceed. Advice will be appreciated. Thanks.
