Cork underlayment has always been the
choice. Inexpensive, cork delivers the control that eliminates
sounds from adjacent or above neighbors.
Engineered Hardwoods & Condominiums
For hardwood floor installations there
are several methods. Most often engineered hardwoods are
chosen for condo installations, but that doesn't rule out
3/4" solid hardwood
with plywood subfloors with proper planning.
Important Tips To
Avoid Installation Failures
When using engineered hardwoods and
cork it is vital to use the same adhesive for the work as with
the actual hardwood. Failure to do so will cause the
underlayment to come unattached from the subfloor. Why? Today's
urethane adhesives used for gluing down hardwood are much
stronger than the more common latex adhesives that were used
in the past for cork underlayment installation.
A successful install requires
different adhesive applications. Unfortunately many less
experienced carpet/vinyl store installers out there aren't
familiar with the methods. Do
they actually own the correct trowel for this type of work?
Our experience tells us no. What happens if they do not follow
the correct trowel recommendation? Over time you may
begin to hear crunchy sounds as the cork releases from the
Unlike vinyl floor installations, more
common 1/4 inch thick cork requires a deeper notched trowel in
the range of 1/8" x 1/8" x 1/8" When used correctly the yield
should be approximately 80 square feet per gallon of adhesive.
Good procedures do not stop there. Once
the cork is laid into the adhesive, bond transferring to the
subfloor must be accomplished. The use of a 100 pound roller
not only insures a good bond, but pushes out any air bubbles
that may be under the cork.
For any type of cork sound deadening
application it is recommended the actual final floor
installation not take place for at least 18 hours, allowing
time for proper bonding
