Floor questions

Iím a little lost on how I should prep my wood for installation. Iím going to pick up this wood to lay down on top of my insulation https://www.lowes.com/pd/Plytanium-2...-4-x-8/3602906

Itís untreated, am I supposed to use a wood sealant on it to protect the wood? If so, do I seal both sides? Or is this unnecessary and I can just screw the wood down? Any help is appreciated, Iím clueless

I wouldn’t spend the time or money to seal the subfloor.

I'd just screw it down untreated, but in the grand scheme it wouldn't cost much to put a coat of Drylok on it just in case there's a water leak. If it was OSB I'd definitely recommend sealing it but plywood should be good to go.

You could seal the joints in case of spilled water.

I think you can put it in as is with no worries. Since it will be sitting on top of your insulation, it shouldn't get soaked even in the case of body leaks or the occasional spilling of something inside. Generally, plywood can get wet and dry out and be pretty much OK (which is not true for OSB).

The plywood that comes in buses from the factory gets badly rotted because it gets soaked for long periods of time.
