Pressure treated 3/4" plywood and Altro Transflor Meta Flooring

[OrionsComfortBus]

While doing research on types of flooring, I came across Altro Transflor Meta. It offers slip resistance in wet or dry situations. Comes in 6.5' wide rolls and sold for $30 per sq yd. Looking at the Storm color. https://www.altrofloors.com/Altro-Transflor-Meta
Got in contact with a "local" rep and discussed the color and pattern to lay it to minimize cost. I'm all about saving money.
Then in a conversation with a service guy at International Santex, He told me that to get the floor done there would cost about $7,000.00 YIKES! Any discounts for retired and military guys? Not really. BUT he does side jobs and if we purchased the material, only have to pay for his labor of removing the old floor, 4 benches and the lift. Then clean and patch the metal before laying new plywood and the Transflor with non PVC reacting adhesive. Then reinstalling the lift and wheelchair tie downs. Thinking of using lifting blocks on two of the bench seats and installing longer seat belts so it will be better suited for adult use.
The plywood is $38 per 4x8 sheet and I would need 6. Non pressure treated is $10 cheaper. Perhaps I can talk the International guy into removing and sealing up the roof escape hatches with sheet metal.
Not in any hurry to get this done as I am still wanting to get the transmission upgraded to a MT643 and get a lower ratio rear diff. Took a short trip and ended up getting about 8 MPG. A bit of stop n go traffic but mostly I was cruisin at 55-60 MPH with the engine at 2900 RPM.

Personally, I wouldn't use any kind of ply that was not at the very least water resistant. Anything short of real "marine grade" and I'd at least treat both sides to a couple of healthy coats of old fashioned shellac. Bus floors get wet, wet wood rots, wet wood rusts out floors.


And everything else you build out inside is on top of whatever is on bottom.

Pressure treated will rust steel real bad. Not sure if putting tar paper under it would be fine or not, but marine grade and varnish or shellac is a better bet. Must say 3/4 marine grade is $100 a sheet here, so not cheap.

The ultimate coating is epoxy.

Marine is not much cheaper here at about $80 a sheet...but having a Shorty helps.

I have priced marine grade plywood, $80+ a sheet. Perhaps I could put a protective layer between the metal and the wood. Save $10 and also coat both sides of the regular plywood before the Altro Transflor. I haven't purchased any materials yet. Plenty of time to adjust things.

Yes...the "new" pressure treating chemicals will definitely eat ordinary steel in a heartbeat. Bunch of contractors discovered this the hard way when they switched from the old arsenic or whatever and had structures collapsing cause the old style nails and screws they used in the new wood dissolved after six months. The new stuff requires a special treatment for any fasteners (or any other metal in contact). Definitely want some kind of barrier in between.
