Hardwood Floor Underlayment?
Is it necessary or desirable to use a soft underlayment when installing
3/4" nail-down hardwood flooring on 3/4" plywood sub-flooring? The floor is above ground level. A Google search turns up a bewildering array of underlayments, but details on applications are often hazy. If you have used an underlayment such as I described I would be obliged if you could name the brand and/or type (material, thickness, means of attaching to the sub-floor, e.g.) Many thanks!

No. It is necessary to be sure the plywood is good quality and nailed firmly to prevent squeaks. My old home has a hardwood rough plank base and then harwood flooring nailed onto that. Jumping up and down on it is like jumping up and down in the paved driveway ...solid. |

I have read that years ago heavy roofing felt (tarpaper) was sometimes used between hardwood flooring and solid timber underlayment. The result was a non-squeaking floor. The felt acted as a cussion, glue and vapor barrier. It is not clear which of the three was the original purpose. If you understand _why_ something is done the way it is, then probably you can decide what and how to do it for yourself. If you _misunderstand_ why something is done the way it is, you can produce a real disaster. -- FF |

All of the installers we work around use felt (tar paper) under solid hardwood flooring. Under the laminate flooring they use some kind of thin blue foam pad which I think is recommended (if not required) by the manufacturer. Mike O. |

Hardwood Floor Underlayment?
Never liked tar paper used inside a house. Offgassing of the tar or pitch,
whatever they use, is not for me. I used a special heavy waxed paper that is made for under hardwood floors. Certainly made it easier to slide the boards together, and to drive them home.
