And thank you Skoolie net , you are the best
I haven't seen it done here on skoolie.net, but I have seen it done on a travel trailer. The installer sprayed foam and then sprayed a healthy coat of undercoating over the foam once it was cured.
I am also looking to minimize lost ceiling height; I will not be doing the rigid foam insulation sub-floor sandwich. My Gillig has very large pass thru storage bays and I intend to spray foam the underneath of the floors in those bays (the "ceilings" of the bays).
For the rest of the under floor areas and entry stairs, I am looking for reasons NOT to spray foam and then undercoat it. I intend to do a thorough cleaning and restoration of the entire undercarriage of the bus prior to doing the foam.
This technique will also allow me (force me?) to do the spray foam in two sessions (interior and exterior) that can be done at different points in the build. This of course is only a "plan" at this point, but again, it sure seems like a viable solution to me...
