Aquabar B Hardwood Flooring Underlayment
Aquabar B is an underlayment that is fast replacing the traditional 15 and 30 pound asphalt felt paper many hardwood flooring professionals have used for years. Some of the advantages and benefits of this product manufactured by Fortifiber include the following.
The older asphalt felt paper or what is also used as roofing paper to keep moisture from entering a home was always somewhat difficult to work with. This is especially apparent with homes that have the final painting completed. Often when working with the felt paper while rolling out near walls or cutting around the perimeter black “scuffs” originating from the oily makeup would mark up walls, baseboard, or door trim. To repair, paint touchup became necessary on drywall or trim painted with flat sheens.
Easier To Work With And Much Lighter in Weight
Aquabar does not have the course texture older felt paper is characterized by. The construction is based on two layers of standard kraft paper with a thin asphalt membrane sandwiched in the middle. An outer surface feel and appearance is smooth, allowing easier shifting or positioning of boards while doing nailed or stapled hardwood floors over wood sub floors.
Overall weight is substantial as well. Fifteen pound felt rolls (432 square feet) will weigh in at approximately 35 pounds while the Aquabar B at 500 square feet per roll about 15 pounds in weight. As an
Aquabar is installed by simply rolling out parallel to the installation starting at the longest parallel wall. To insure maximum benefit, overlap the seams by approximately four inches working outwards in the area being installed. Our suggestion is to lay only two swaths and fasten with a staple gun to prevent movement. Laying out too much with constant foot traffic back and forth will lead to tearing of the underlayment.
