Particle Board as Subfloor?
#1

My cousin recently helped me by installing a new subfloor in preparation of laying sheet vinyl. However, he used particle board. Now I'm being told that the particle board is not acceptable, and that I will need to have it pulled up and use plywood. On the other hand, I see other messages that refer to using particle board. Is it a critical enough issue to warrant the expense of redoing the subfloor? Can I put a thinner plywood directly over the particle board?

Glue and use long staples to adhere ¼" birch finish grade hardwood plywood underlayment, to the particle board.
It's not perfect, or to required specifications, but it will be ok as long as NO WATER gets to the particle board.
