Treating OSB for Vinyl Flooring in Bathroom

[roboputt]

Hi,

I have 18mm OSB laid down in a new bathroom, screwed into joists beneath. I've probably sunk the screw heads a bit much, and there are some joins where one board butts up against another. Wondering what the best thing to do is beneath vinyl flooring.

Wondered about a resin of some kind and painting that on. I assume it would cover the screw head dimples and also the cracks between boards, as well as helping to increase the moisture resistance. Any thoughts please?

Thanks

OP,
Could you post a couple of pics of the floor - show a bit of detail and a context.
What kind of vinyl do you have in mind?
