Trillium Floor Repair

[ChrisDunbar]

I bought my trailer under the impression that the floor by the stove/fridge and the couch was rotten and expecting a ton of work. A while back I drilled into the floor just to see what was going on. To my surprise dry wood came out. Leads me to believe that the fiberglass has just lifted up in that corner.

Now I'm scratching my head to determine the best way to repair just the corner. Both doors under the couch have trouble opening over the floor because it's "bubbled." Towards the back of the trailer everything seems fine.

Has anyone had this issue? What would the cause be? Should I cut out the offending fiberglass and redo it? Then I could get a real inspection of the wood as well.

I would like to refinish the flooring so would like to have the flattest floor before I begin.

Our 1978 Trillium 4500 has similar issues where the interior fiberglass components the comprise the floor don't lay flat. In our case either a previous owner or the manufacturer put some screws through the fiberglass floor into the plywood. To install finish flooring, I would have to remove the screws and somehow secure the fiberglass flat to the plywood. I would probably use construction adhesive and hold in place with some heavy weights, e.g., sandbags.

Edit: On our FG floor, there is also a 1/2" gap between 2 interior FG modules (i.e., the plywood is exposed here). I would probably grind the edges here and fill with bondo-glass.

you might try trimming the doors or move the doors up.

I'll likely have to do this anyway depending on what flooring I install but that doesn't address the actual issue.

I've thought about this as well. Cut the floor to relieve the wavyness, peel it back, and then PL it all back down.
