Just I suspected water leaking from clogged window channels (before I owned camper) has rotted the O.S.B. flooring on the back of the camper, I was able in one spot to puts a pocket knife clear thru the flooring! Now what, the rest of flooring is good. Any advice, suggestions? I know the flooring and paneling will have to be remove and new installed, luckily the rear of the rig has a fiberglass cap much like the fronts of most fifth wheel’ do. Any input is appreciated.
You could also cut out the bad spot and then add a connection piece underneath then place new floor section in. Also would use some glue along with screws to hold everything together. Once dried it would make it one piece again then replace the floor covering. I have done this process many times when I couldn’t replace the complete floor. In fact it was stronger than the rest by far. You might want to also use a dehumidifier for a while to make sure you get as much moisture out as possible. A few days would make quite a difference.
I should have added that yes they do make a “paint” that will seal any structure pieces like 2/2s in side walls. I have used that before by myself have not had any luck using the epoxy that can be added to the floor and let it reseal and make solid again. Just my experiences from past.
