Using nails long enough to reach the solid subfloor should be fine. I would probably not remove it either. I did remove a 3/4 particleboard underlayment for a kitchen I did, but was not planning on using extra-long nails. Even there, I'm not certain it actually made that much difference.
Read your floor manufacturer warranty to see if it will affect warranty. If not important, or unaffected, leave it. Particleboard provides a very flat underlayment, it just doesn't serve a structural function. |
