OSB over Pressure Treated deck?

[HeelSpur]

I have an 8x10 PT deck and want to turn the deck into a pantry. What do you think about osb over the decking boards? It will be very lightly traveled and have linoleum on top of it.

I'd use 3/4 exterior sheathing. More than likely a vapor barrier as well. Are the deck boards solid?

I would think putting something down between the deck boards and the OSB would be a good idea. I think you would want to keep moisture from coming up from the bottom, getting into the OSB and ruining it over time.

The deck is solid, have never done this or seen it done before so looking for pro's and cons.
