So I've already completed the upstairs which was 3/8 engineered stapled to the 3/4 ply subfloor.

For the 1st floor, I'm planning install the same 3/8 engineered over concrete and decided to do staple it to a floating subfloor (We like the feeling of the additional plywood that provides a solid feeling as opposed to directly gluing).

Here's what I'm planning:

1) On Ground Install (Texas)
2) 6 mil virgin poly over concrete
3) 2 layers of 3/8 plywood, 2nd layer at a 90 degree angle using urethane glue and 5/8 staples
4) Aquabar B underlayment (instead of felt due to smell and black smudges)
5) 3/8 engineered

Now for my question, I had a Calcium Chloride test from before when we were thinking of a glue down. So since I had it I decided to use it just to see. The results are 4.01 lbs. and 4.21 lbs.

I read somewhere online where the NWFA states it's OK as long as there results are below 7 lbs. and you are using a vapor retarder. But I could not confirm this since I don't have the actual installation guidelines from NWFA.

With those results and the method of install I am using, should I be concerned?

Thanks in advance.
