Steps
Store gypsum panels flat, fully and evenly supported, on a firm, dry, level, structurally sound surface
Limit stack height per GA-801 guidance and ensure stacks are stable and cannot topple
Keep panels off wet or damp surfaces and away from locations where they could be dripped on by grease, oil, or condensation
Remove any shipping plastic wrap promptly upon delivery/warehouse storage to prevent trapped moisture and mold growth
Avoid storing panels on edge for extended periods, since this can cause warping or sagging
Known gotchas
Confirm the current GA-801 edition being referenced (GA-801-2023 supersedes GA-801-2017); older printed copies on the jobsite may reference outdated guidance
Leaving factory shrink-wrap on stored panels traps condensation and is a common cause of mold/discoloration claims against the supplier or installer
Storing panels on edge instead of flat, even briefly, is a frequent cause of bowed board that fails at hanging
