Questions on engineered Brazilian Koa?

I guys I am going to be installing 500 sqft 1/2" x 5" wide engineered Brazilian koa in a bed room on the second floor with a plywood subfloor. I plan on nailing this floor down with cleats.

I have the read the specs and since this is my first time with this type of floor I have some questions and would some feedback.

1- the specs say that I can use 15lb felt as an underlayment which is considerably cheaper then using any store bought underlayment, has anyone ever used this an are there any draw back to going this route?

2- the specs say to leave a 1/2" gap between walls, etc, this sounds like a lot of room to leave. I live in Arizona which is a pretty dry state and have always used 1/4" gaps and never had any problems (but that was also a glue down floor) the reason I ask is that doesnt seem to leave enough room for the 1/4 round trim to cover the gap to sit on.

Thanks for any advice and any tips would be appreciated too.

15# felt is a perfect underlayment and will give you no issues.

If you remove the baseboard and install the flooring with 1/2" spacing, the baseboard (1/2") plus shoe molding (1/2") will more than cover the edge.

I concur with Z. Remove the baseboards and install with the 1/2" gap, and use 15# felt. I do it all the time, and have never given it another thought. Laying your felt along the run make sure you don't overlap it. It can cause problems if the overlap falls between two boards. I have had that puky 1/16" become obvious before. Luckily before I went too far.

thanks for the help guys.

I didnt plan on pulling off the baseboard is the half inch that critical?

should I staple down the felt or just let it float?

do I run the felt the same direction as the floor?

Thanks

Why would you not pull the baseboards? Makes no sense to me to leave out a basic step. The floor will look more finished and will be easier to install around doors and openings if the baseboards are pulled. Can understand why you would want to complicate the install to save a couple of minutes.

If you don't pull the base you'll at least need to add shoe mold [or quarter round ] How high is the base off of the subfloor?

If there are plaster walls, you can do a lot of damage pulling the baseboards. I would need to know the age of the house before I said they need to come out.
