Thanks for your idea of using that liquid rubber, that could really work. I have used plastic, expensive thick plastic that ripped and was not effective at all. because of my lcoation, it's tough to discreetly bring all that plywood in. I have three total rooms that i woudl love to protect. Do you think that I could use a 2x4 border with a vinyl floor instead of plywood and cover that? The room is currently carpeted, so I am wondering if the vinyl floor would be strong enough to keep the rubber floor solid. Any ideas? Thanks again man, this is the best idea I have seen so far for protecting my floors.
