INSTRUCTIONS FOR CORK UNDERLAYMENT
When noise transmission
is an issue, Natural CORK Sound Control Underlayment
provides a natural and economical solution in
combination with other flooring materials. Easy to
install, environmentally friendly cork underlayment does
not deteriorate after years of use. Natural CORK
Underlayment is recommended for sound reduction and
stress crack protection. It has been independently
tested according to ASTM standards for acoustical
values.
INSTALLATION
Read and understand
Installation Guidelines completely before beginning
installation.
SURFACE PREPARATION
Surfaces must be clean,
dry and smooth, free of voids, projections loose
materials, oil, grease, sealers, and all other surface
contaminants. Maximum floor variation is 1/8” in 10’.
Concrete slabs requiring patching or leveling should be
repaired with Portland cement based material.
CREATING AN ISOLATION BARRIER
An isolation barrier will further reduce sound
transmission. This barrier is adhered to the lower
portion of walls, not to the floor.
Unroll cork and cut 2”
wide strips. Apply a small amount of CCT 500
Underlayment Adhesive along one long side. With the
adhesive edge closest to the floor, install isolation
barrier around the entire perimeter of the room. Buff
edges at joints.
INSTALLING SOUND CONTROL UNDERLAYMENT
Unroll cork and cut to the
desired length. Lay cork loosely over area to be
installed. Both edges of the roll must curl down towards
the sub floor. If the ends curl up, flip the material
over. Butt cork directly against the isolation barrier
already installed. Pull the loose laid material backs at
least half its length. Using a 3/32” x 3/32” x 3/32”
v-notch trowel, apply Natural CORK CCT 500 Underlayment
Adhesive to the substrate. Spread rate is 100 sq. ft.
per gallon. Gently return the pulled back material and
roll in both directions with a 100lb. roller. Repeat
this procedure for the other half of the sheet. Proceed
to cover entire floor making sure all joints butt
together tightly. Allow cork adhesive to take a firm set
prior to installing surface flooring material.
A-WOOD FLOORING INSTALLATION
Follow industry standards
and wood floor manufacturer recommendations for subfloor
moisture content, design, layout, and application of
wood flooring materials.
 |
1. |
|
Install wood floor with recommended adhesive
over the sound control underlayment. |
| |
2. |
|
After wood
floor is installed, trim isolation barrier ¼”
below the finished floor surface. |
B-CERAMIC TILE
FLOORING INSTALLATION
|
|
1. |
|
Install ceramic tile according to applicable
ANSI standards using Hydriment Single-Flex;
Hydroment PM; or Tile-Mate thin set mortar mixed
with #425 Flex-a-lastic- Admixture. |
| |
2. |
|
Refer to
setting mortar data sheet for complete
instructions. |
| |
3. |
|
After the tile
floor has been installed, trim isolation barrier
¼” below the finished floor surface. |
| |
4. |
|
Caulk the
trimmed areas with a bead of acoustical sealant
flush to the finished floor. |
C-CARPET
OR LAMINATE FLOORING INSTALLATION
Lay cork loosely over area to be covered. Install
surface flooring materials. Do not use nails or screws
during installation. After carpet or laminate floor is
installed, trim isolation barrier ¼” below the finished
floor surface. |
