Hi, I hope I can find the answer for this here because this is the first time the internet has failed me!
We are installing 1200 sq ft of 4" prefinished hickory solid 3/4in hardwood (Mullican). It will be going on the first level of our home, which is above grade. We currently have tile floors over a plywood subfloor. The tile and backerboard will be demoed tomorrow.
We contacted the manufacturer and they recommended gluing and nailing the floor, using a liquid nails type glue in a serpentine pattern on the boards. If we glue down the floor am I correct in assuming we can't use a vapor barrier?
If we can't use a vapor barrier, will that cause more issues/movement in the floor?
Would it be a bad idea to just nail the floor?
I'm not sure if they recommended this because its a 4" board or because its hickory, but its a little frustrating because on the product page on the manufacturer's website it says nail. Nothing about glue.
Thank you for any insight/expertise you can offer!
