I am building a 4x2x2 Birch Plywood Enclosure. I have stained the inside and out and polyurethaned it in and out (a 2-in-1 stain and poly). I am going to seal the inside with mod podge to kill any lingering fumes or toxins. This got me to thinking. Can I just put 2-3 coats of Mod Podge on the wood flooring and be done with it and not have to worry about tiling? I know the mod podge on the rock/grout items I made will make cleanup easy so I wondered if I could do the same with the wood flooring of the enclosure. Any thoughts or opinions?
