Used to glue the FloorMuffler to the sub-floor, HPPA is a revolutionary breakthrough in adhesive technology. A solvent-free, latex resin emulsion, which allows the contractor to install the non-porous pad within 20-30 minutes after spreading the FloorMuffler HPPA. This will increase productivity without compromising the integrity of the installation. The ultra-fast flash time grabs The FloorMuffler and holds the pad in place while the installer lays the wood flooring. Available in 4 gallon pails and covers approximately 540 square feet per pail.
