My only concern with vinyl sealant would be if it wouldn't allow any trapped moisture in the flooring to
escape. While it would go a long way of protecting your floor of any moisture from inside and I guess like a spray-on truck bedliner, it'd be super durable, but I just wonder it it may seal the floor too much.
I do know in home construction you have to allow wood floors & walls to "breathe", otherwise you're inviting dryrot or worse. An example is putting weatherseal on a wood deck, you apply it on top to keep rain from getting into the wood but you don't apply it to the underside of the deck to let the wood breathe.
Of course, that may not be the case with
Fiberglass Eggs with floors made with
fiberglass impregnated plywood, sealed
fiberglass floors, ect.
My Scamp's carpeting was totally nasty when I got it, so I pulled it up and replaced it with interlocking faux hardwood flooring. It's was just so easy to install and looks great. I bought a lesser priced grade of flooring that was closeout priced at Lowes for $24 for a 6 sq. ft. pack. Two packs floored my
Scamp with leftovers. Took one day to install & trim. It has a blond oak veneer that closely matched the Scamps stock dinette table veneer.
I can sweep it clean in a minute. I never could understand why have wall to wall carpet when a little area rug is so much easier to maintain...just take it outside and shake the dust out, wash it with a gardenhose & a bit of laundry soap, rinse and let dry in the sun.
