I had it in the house when I moved in...they all lifted and dirt liked to get in the cracks. I'd think the typical heat/ cool cycles of a trailer that isn't in a controlled environment would cause them to lift prematurely, maybe the adhesives are better now though. You'd need to seal the plywood with something like an epoxy and then sand it level so that you got good adhesion, and use a roller on each tile. Check the application instructions. I'd think you're better off with sheet vinyl and a troweled adhesive and then capture the edges with a base shoe or the aluminum cove molding. While it's not cheap, Marmoleum gives you a fantastic vintage appearance in a standy. It's thick and won't allow any rocks to scratch. Done it 2x now, I won't do anything but IT on any future standy builds. Just my experience. Doug
Against my wishes and my better judgement... my wife picked a peel and stick for a bathroom remodel project. To make matters worse the design called for 3/8" spacing and, wait for it, grout. [sigh]That's right, he said peel & stick vinyl tile with grout joints.[/sigh]
I laid the tile over new 3/4 OSB T&G and per manufacturer's recommendation I used a bonding primer on the bare OSB.
That was 6 years ago and not a single tile has budged, not even the grout. This was 'the kids' bathroom and the floor has seen its share of water and wet towels etc.
I still don't like the idea but I have had to eat some crow over the deal. I give all the credit to the bonding primer.
