Hi all,
I'm at the point in my restoration where I have pulled everything out back to the bare bone shell. With all the cabinetry removed and the old flooring pulled up I can see that the floor (the floor is 3/4" plywood with a layer of
fiberglass mat over top which is fiberglassed right into the shell) is far from level.
As you can see from the photo the floor undulates up and down along the trailers length. I have included a sketch of the floor set up to hopefully better explain my issue. The sketch shows the 3/4 inch plywood sheets that make up the floor of the trailer. These plywood sheets are covered in a layer of
fiberglass mat which is also what connects them at the joints. The arrows in the sketch show the locations of the frame rails running side to side under the trailer which support the floor. As you can see the locations that the plywood sheets are joined are not located above frame rails. I see this as an area of weakness (I am not very experienced with
fiberglass and don't know what kind of strength this type of join would withstand)? Also where the plywood has been joined it looks like the fiberglass was built up thicker (I'm guessing for strength) causing the floor to undulate up and down from joint to joint.
My questions are:
1. Is the floor strong enough as is or should more fiberglass mat be added to the joints?
2. In order to level the floor I see two possible options:
a. Add more fiberglass mat between the joints to build them up the the level of the joints
b. Use a pour able epoxy floor leveling material?
