I'm in the middle of multiple projects on a 1990 16' Scamp
(layout 4). I found some floor rot under the water heater. The heater sits underneath the kitchen cabinet above the wheel well. Probably only a 10"x10" area that butts up to the outer wall and the wheel well. When inspecting the floor from underneath that area is soft and not very thick and in danger of breaking out completely.
From the inside it looks like Scamp's process was to put the floor in and then 2" strips of fiberglass covered the edges of the wood flooring at the wall, wheel well and side cabinet. The wood under the fiberglass strips has been rotted away enough that the strips have separated.
My thought was to apply a wood rot hardener (Git Rot) and then build up the wood floor with plastiwood. I'd then sand and apply fiberglass resin over the top.
I am totally new to this type of work so any advice would be appreciated. Is this a sufficient way to fix this problem or do I need to consider replacing that section of the floor completely. I have no idea how I'd do that!
Any other alternatives?
Thanks for your help.
