So, I want to redo the floor in a cheap little cabin. The subfloor is
particle board, covered with linoleum tile, subsequently carpeted.
I've removed the carpet and tile (shingle rake was helpful for that).
The particle board has gotten wet in some places and softened and
gotten lumpy, and doesn't smell very good. I'm thinking of trying to
seal it with some sort of paint or varnish or something, before
putting a plank floor on. Something that would soak in and harden and
restore some integrity to the soft spots, and seal in the musty
smell. Anyone have an idea as to what might work, or general advice
on dealing with particle board subfloors?


It is already crap. Replace it. Any shortcut now will be a big deal later.
Could be moldy if it stinks.


Is it adequate simply to replace the soft lumpy section (about 6 sq. ft.
near the sink in my case) or do you advise replacing the whole
underlayment? What material is best to use under vinyl tiles instead of
particleboard?
