treatments to Thrifty Board

I am lining the walls of my bathroom, excluding the shower/tub enclosure, with 4 x 8 Thrifty Board. The other option was plastic but I did not think a matt surface would offer any cleanability at all. (Smudgeability).
Anyway, what I want to know it whether I can treat the backs and edges with a sealer to make it more water resistant? Or will this cause buckling? I also have a two part epoxy I intend to roll on to the completed wall
since the coating they give you is little better than a primer.
Will the panels remain flat if I roll a finish on the back with panel flat on floor? I know I am not the first to try this so I might as well ask in advance.

If I were to paint the backside I'd use a solvent based coating as it would be less likely to cause warping along with providing better moisture protection than a latex coating would.

I also would question why you would want to use this?

I am not sure I am talking about the same product you are referring to. The material I have seen as a shiny surface.
Shiny means smooth so you would have to rough it up before painting it.

Also it is flimsy so I would only use it if it had a backer re: drywall etc.
So why bother with this when you could just use drywall?

There is nothing you can do with that panel to make it last.
What is made for damp areas are FRP panels made of solid fibreglass.

Of course, I have to agree that objectively it is a sub-cheap stuff, enough I understandable to raise some hackles even, but I once saw it done as a cheap fast bathroom and it was done well. Not to say it would last. It was a tenancy anyway.
But said to tell I could not acquire the skills to do it as well as he did. I think in 1970 he charged $150 for the wall job. But he did it in a few hours and it was a marvel.
But actually this may be fine with the ambient moisture in any bathroom, since the shower-tub enclosure is clad with cement board.
In any case, my quest for a cheap, flashy bathroom has advanced. I painted the backs/edges with Thompsons for wood treatment and I was happy it did not cause any bending. So now, I will feel assured that a leak or a spill on the floor will not lead to wavy walls.
At the moment I am tasked with trimming an edge sufficiently to conceal behind the plastic corner trim. The great skill in this job is accurately cutting each piece. That's what I have not got. My biggest problem is I cut out a piece to go around the door. This leggy thing must fit againt the wall and either side of the door and remain within the concealment of the trim. That, or auto bondo, which would be okay since I am epoxying the whole thing once it is up. I will have the kind of bathroom that inspires grafffiti.

I have found it is necessary to cut and fit each piece before attaching anything. Now I am next going to epoxy each panel. For this purpose I have them in their places, although I would like it better if they were horizontal. But no room for all of that. This way the trim will not be painted over.
