Pine T&G Floorboard - Can you leave it unfinished if covering?

[Argute]

Simple one, hopefully.

I’ve had to replace a couple sections of pine flooring due to a leak.

I will be covering with ply and then vinyl / LVT (I’d rather have a wooden floor but half the room’s floor is concrete so I can’t…)

I’ve covered with a boron treatment to protect from dry/wet rot - can I leave them as is now or is it wise to apply a varnish to protect them further? They’ll be covered and won’t be exposed in the future.

thanks

Your choice, really. If you seal it with a lacquer or something else dirt won't end up being ingrained, however, there are lots of Victorian houses out there that have bare timber boards. And in any case you are going to cover it

Leave them as they are.

Seems straightforwards and one less job to do then.

thanks
