Questions & Answers

Can this be used with wood laminate flooring?

basically it's all in the question, we are planning on putting down some wood laminate flooring and from everything I can tell this would be suitable for it, or am I mistaken? We would join the strips with some aluminum tape to make sure there are no gaps between the strips. Any advice would be greatly appreciated thank you
Asked by: Debarto
Laminate flooring manufacturers usually require a cushioning pad under their floating flooring to transition subfloor irregularities, stop moisture vapor and/or deaden sound. Aquabar is not a pad, neither is roofing felt. Aquabar is a Vapor retarder which will not trap moisture for use under nail down wood floors.

Can I put down multiple layers of this underlayment between plywood and nailed-down hardwood?

For added padding and soundproofing, can I put down multiple layers of this underlayment between plywood and nailed-down hardwood (3/4" red oak)? Thank you

is this suitable for use over crawl space?

I am using it over 3/4" T&G OSB and will be installing 3/4" hickory over top. Don't really want to use #15 felt paper, will this work over a crawl space?
Asked by: abugarcias
It will work great on top of the wood subfloor when nailed down. The manufaturer's installation guidelines on their website, recommends installing their Moistop Ultra 6 on the ground in a crawl space before installing Aquabar over the subfloor for more vapor protection.

Rated 5 out of 5 by from Aquabar "B"est This underlayment is great. It was used under my stranded bamboo flooring. Thick enough so it doesn't rip easily, thin enough to be able to overlap without issues. Helpful lines on the paper for overlapping and keeping straight lines. No mess. Extremely easy to put down. I would definitely use this again. Don't mess around with felt, asphalt, or rosin paper by this instead!
