I'm planning to lay some cheap ish vinyl wood effect plank things on top of tongue and groove, which is in pretty poor condition. This is a temporary solution, to stop imminently crawling dd getting splinters - we plan to get a nice floor at some point. Although round here temporary solutions have a habit of lasting longer than we had planned.
My question: do I really need to seal the floorboards with PVA? Or can I just lightly sand, damp dust, and leave to dry?
