Use and Care Manual
Installation Instructions
1. All subfloors and substrates must be inspected
prior to installation. They should be smooth and
level to prevent irregularities in the performance
of the QuietSound™ acoustical underlayment. All
recommendations and requirements provided by
the subfloor manufacturer must be followed and the
surface must meet the requirements of ACI 117R.
2. Wood subfloors must be prepared according to ANSI
L/360 standards when supporting grouted floor
coverings such as tile. Particleboard, chipboard,
Masonite and Luan/lauan are not suitable subfloors.
3. Concrete subfloors must be fully cured and
permanently dry. ASTM F710 requires the subfloor
to be free of dust, solvent, paint, wax, oil, grease,
asphalt, sealers, curing and hardening compounds,
alkaline salts, old adhesive residue and other
extraneous materials. To avoid moisture-related
flooring failures, test the concrete or other cement-like
materials for moisture before installation.
4. Remove all traces of old adhesives, paint or other
debris by scraping, sanding or scarifying the
substrate. Do not use solvents.
5. Grind all high spots until level and fill low spots with
an approved patching/leveling compound. Allow
patching/leveling compound to dry thoroughly.
1. QuietSound™ acoustical underlayment should be
delivered to the job site in its original, unopened
packaging with all labels intact and stored
appropriately to prevent damage.
2. Inspect all QuietSound™ acoustical underlayment for
visual defects before gluing the product to the subfloor.
Under our warranty, U.S. Rubber is not responsible for
any incidental or consequential damages, including,
but not limited to, a labor claim for installation or
removal of product with visually apparent defects.
3. QuietSound™ acoustical underlayment and any
adhesive must be acclimated at room temperature
for a minimum of 24 hours before commencing the
installation.
4. QuietSound™ acoustical underlayment is stretched
slightly when it is rolled at the factory. At the job site,
the installer should allow all cuts to relax before gluing
down. Shaking the product once it is unrolled can
help accelerate the relaxation of the product.
Job Site Preparations
Do not commence installation until suitable temperature and humidity controls are operable and working. A suitably “clean”
means of ingress and egress is also required.
Base Preparations
6. All saw cuts (control joints), cracks, indentations and
other nonmoving joints in the concrete must be filled
with an approved patching/leveling compound.
Allow patching/leveling material to dry thoroughly.
