Bus floor

Hi! were are in the beginning process of gutting a bus. We have gotten down to the sub floor and are having trouble getting it out. We were wondering if anyone has kept the original sub floor and sealed it with epoxy or fiberglass resin. We would put a thin layer of insulation above that between a new sub floor. We our also plan on applying an undercoat to the bus also. Are there any long term problems this could lead to? or has anyone had any experience using fiberglass resin or epoxy. Thanks!!

Circular saw with a demo blade and depth set to just less than the thickness of the plywood (3/4"), make side-to-side and front-to-back cuts in the floor, about a foot apart. Pry up squares of plywood one at a time EZPZ. You want that plywood out.

What type of bus do you have? Some are quite different. Filling out the user profile will help you get an appropriate answer.

This is a very good point. On some buses the plywood is all there is and my advice would not be the best. On most, though, it's plywood on top of sheet metal.

We considered leaving our plywood floor b/c our bus is newer than most, and no indication of rust. I am glad we decided to remove it. I could not believe how much moisture and rust was under the plywood, as there is not even a hint of visible rust anywhere else. My advice, which is only as good as what you paid for it (nothing), is to pull the floor up. We used a long (6’) rock busting bar with a flat end on it, had the whole floor ripped out in an hour.

So far, I have not read even a single post that someone removed the subfloor and regretted it. Most have removed the subfloor and discovered rust.
