Hello there hope you’re okay yes i would highly recommend not put in a vinyl plank straight on top or floorboards for one floor boards are not treated and yes you would need to put a wpb plywood down before installing and probably will take around about a month for the lions underneath to start showing through so i would highly recommend not installing on top of floorboards thanks jordon
Hi i would contact the main manufacturer about the product and find out whether they are meant to be like that if not you need to call up a local rap and get them to come out to have a look hopefully they can point you in the right direction but if they are 40 or misprint they have to change them or give you a refund
