Flooring
I asked this before but didn't get any thoughts so trying again.
My bus has a wood floor thats about 1 1/2 in thick, just about ready to start the interior & wondering should I coat the plywood with Red Guard or maybe coat it with flexseal ? I'm planning on 1 1/2in insulation & 3/4 in plywood subfloor on top of that. Do I also need to put in a barrier between insulation & subfloor but then I think if I do that any moister will get trapped in the insulation.
Thoughts??
