Hello, I plan to use 12mm laminate floor in my basement. I have very low moisture level, and by m...
Asked by Konrad May 9, 20188
AnswersAquabar is really good stuff. II have used it on two installations - both on wood subfloors. Even in a low moisture environment, concrete slab will release some moisture. Myself, I would use a moisture barrier like PVC- plastic in a basement-over-concrete installation.
can you glue wood to this
Asked by tom November 9, 20197
AnswersMy guess is, you are looking for a more affordable alternative to the Tavy membrane process. I don't blame you. My guess is it would work.
I have concrete floor, lay the fortifiber underlayment then thinset then tile? Is this how to use it?
Asked by Edy September 20, 20187
AnswersThe Aquabar "B" underlayment is typical used for wood flooring installations. Best is to use an Elastomeric Membrane waterproofing and crack prevention on a concrete sub floor, like RedGard.

Can I staple this on top of wooden subfloor?
Asked by Ws6ramair June 21, 20186
AnswersYes you can staple this to a wooden subfloor, but not needed. It Can be used for vapor barrier on either a slab concrete or wood subfloor.
can this be used for underlayment for floating laminate on a concrete subfloor
Asked by MD October 12, 20186

Asked by Kay September 24, 20186
AnswersThis wouldn't work by itself. There would be no good way to securely attach the Aquabar to the linoleum and similarly the Aquabar to the tile. While I have never done it you can supposedly lay tile directly over the linoleum if it is sound (you would have to research this further though as the details really matter for good adhesion).
Will this product work well in my bathroom for an underlayment over plywood for tile?
Asked by AT May 10, 20206
AnswersWe used it as a recommended under layment for the Eucalyptus flooring we installed. This floor was glued & nailed. We really don't think the paper layer will adhere to the tile to make it a serviceable surface without problems.
Can I put this directly over my bahroom wooden subfloor, then thinset, backboard, then tile?
Asked by Ws6ramair June 30, 20185
AnswersYes , over your subfloor however the thinset doesn’t go over this . Thinset is what is used to adhere the tile to the backer board.
Can this be used with wood laminate flooring?
Asked by Debarto March 21, 20155
AnswersLaminate 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.

It's not what in the specification. It's only <7 mil, not claimed 12 mil!

Ordered online according to the specification. However, 7 mil is far away from 12 mil. It will be returned tomorrow to the store.

Great product
December 26, 2018
Used this product on top of plywood. This priduct made laying the flooring very easy. Stayed in place once it was rolled onto the plywood. Did not use anything to hold in place. I will use throughout the whole house. I will recommend this product.

Worked great! Use under Bamboo hardwood, just rolled out and cut. Did not staple, just put hardwood down right on top. Also used it to put under hardwood and tread nose that I was gluing to make my own hardwood stair treads. The Aquabar kept the glue squeeze out from sticking to the plywood that I was making my stair tread on.
National Wood Flooring Association Approved Vapor Retarder
October 9, 2013
This product is great in that it provides the necessary vapor protection when installing wood floors in rooms over unfinished spaces (in my case, the living room over the basement). It is an product approved by the NWFA as a underlayment for wood and tile.
This is a much cleaner product to user over asphalt / felt paper, as the asphalt material is sandwiched in between to layers of kraft paper. In addition, rosin paper and felt paper are no longer recommended underlayments. A penny more per square foot compared to rosin paper.
Product was shipped faster than the estimated delivery. Installation is a breeze, especially with the markings showing your where to overlap adjacent sheets (min 4").
No need to attach the paper to the subfloor, as it will be held in place with the nails or staples holding down the wood floor. I just did one line of staples near the middle to hold the paper in place.
