I'm going to be installing some Brazilian Cherry prefinished wood floor in older home. It was built in 1906 and it's two stories. Lower story is a basement with a ceiling that's close to 8 ft tall. About 3/4 of the basement is a concrete floor or concrete surfaces. The rest of it is dirt covered with black plastic.
The underlayment for this engineered 5-in Brazilian cherry is a dense thin felt with an aluminum foil moisture barrier. The floor in one bedroom is 80% bare plywood, but the other 20% of the room is covered in linoleum. I don't have a clue what the perm rating is on linoleum.
There is a smaller bedroom about 10x11 or less and a hallway that's 9x3 and 1/2. these both have linoleum on them too.
I'm wondering if it's a good idea or a bad idea to unroll another layer of protection at least on the plywood areas. I'm thinking of aquabar b paper, overlapped and taped, and then unrolling the synthetic felt on top of that. Since the underlayment already has a vapor layer on it, would at adding the aquabar paper on the floor first be a good idea or a bad idea?
