Rosin paper or felt under hardwood.

You are better off just flipping the shots over after you cut them. Rosin paper offers no benefit to the assembly whatsover. A lot of the squeaking on older floors are actually the nails moving in the subfloor so today we use threaded nails and for the most part and that solves that problem. Asphalt felt paper is installed by rolling out on the subfloor before installing nail down products.

Sure there may have been felt paper or rosin paper installed under the hardwood floors or behind the siding but these pieces weren t as much about vapor protection as they were about stopping rainwater. Hardwood flooring can increase your home s value. While overlapping of underlayment on the 15 is often up for debate the 30 pound product will be too thick for this purpose and should be butted together. Your first task is preparing the surface that the hardwood will lie on which means deciding whether you need to use felt paper under the hardwood.

It won t mark walls and it is a more effective vapor retarder than 15 felt. Thus make a decision that makes sense given your particular job site issues and don t work under the illusion that underlay paper is an easy solution to moisture migration or squeaking in hardwood flooring installation. Adding either a layer of felt or rosin paper isolates the wood layers and helps to minimize squeaking wood to wood. After the subfloor is down roll out either felt paper or rosin paper starting next to the longest wall.

When old houses were built there was no such thing as a vapor barrier. Stapling is not the best way to do it. Felt paper will not help either of these conditions. While manufacturers have made hardwood floors easy to install you do need to take a few steps to prepare the room to make installation easier.
