My father in law said build the shed floor with 3/4 inch plywood, not OSB
He told me OSB would swell up and rot within a year if it got wet. I figured he was just being old school and cheap, so I went with OSB anyway to save $40 on a 10x12 shed build last spring. Well guess who was under the shed yesterday pulling out floorboards that look like sponges after a few rainy months? He gave me that look like 'I told you so' and didn't say a word. Anyone else have a relative who was annoyingly right about building materials?

Learned that same lesson with a chicken coop floor. OSB looked fine for two months then turned into a sponge. Switched to pressure treated plywood on the rebuild. Never again.

Man, hard disagree @leo603. OSB is fine if you keep it dry and seal it right. Pressure treated is overkill for a coop floor unless you're literally flooding it. I've had OSB under a tarp for years and it's fine.
