General Instructions
Storage Conditions
All flooring product should be stored in a climate-controlled area,
which is equal to the environment it will be installed. Flooring
should not be delivered to the job site until all “wet trades” are
completed, and the subfloor moisture has been determined to meet
the recommended moisture level required for installation. ( T o
assure the moisture warranty will be valid in case of future
problems please document the method and results of
testing prior to installing. Keep a copy for records and give
a copy to the homeowner with the warranty registration.)
Packaging must not be removed prior to installation. A maximum
moisture variance not to exceed 4% difference between the
subfloor and the flooring must exist prior to installation. Do not
open flooring packaging prior to installing the product. Upon
delivery to job site, stack unopened boxes above grade only in a
“waffle” pattern to allow for airflow until installation.
grain mixing. This is extremely important when working with wood
specie or grades that have drastic color variation. Loose lay rows
before installing, and remove any boards that are aesthetically
unpleasing or have natural defects.
Do not install any material that is defective or may have
been damaged. We do not accept responsibility for any
costs incurred when plank(s) with visible defects have
been permanently installed.
The key to a smooth installation is making sure there is no
deflection in the starter row during installation, both at the back
and sides of each row. This is of most concern when using the
floating method of installation, as the starting row is not secured to
the subfloor. Begin installing the floor in a stair step fashion. Work
each successive plank into place, continuing the stair step process
until three full rows have been installed. After three full rows are in
place, re-check that you are square to the adjacent wall, and all
wedges are secure. Since the floor is floating, repositioning the
installed flooring and re-setting the wedges during initial set-up will
allow for minor adjustments to the positioning of the installed
planks. Although not necessary, allowing the initial three rows to sit
for one hour will securely bond the planks together prior to
installing the rest of the floor. If you leave the floor for any length
of time, be sure all planks are securely installed in the correct
position, as adjustments become difficult over time, and securely
bond in one hour.
Pre-Installation Guarantee
Although each board is subject to stringent quality assurance
checks before it leaves our factory, the installer should inspect
again before installation. Any defects should be reported, and we
will immediately arrange for replacements to be provided. We offer
pre-installation guarantee of our products returned
unused/unopened.
Pre-Installation Planning (Requirements)
Interior walls should be complete of all “wet trade” work, and
should be thoroughly dry prior to installation.
The use of a backer board is recommended to assist with the
starting of the first few rows. Begin installing the Floating
Engineered against the secured backer board. After the floor is
installed across the room, remove the backer board, and install the
final piece of wood and matching foam underlayment.
The relative humidity must be between 35-55% before installation
can begin, and should remain at this level year round. Flooring
installed or exposed to conditions outside the
recommended levels will react i n c o n s i s t e n t with normal
expectations, and void the manufacturing warranty.
Use a minimum 20-ounce hammer to tap into the block. Engage
the end joint first, and work the board in at an angle, starting from
the outside, and tapping toward the previously installed plank. Use
firm even strokes against the tongue side only.
The heating and cooling system must be installed and maintaining
a minimum 60°F for at least 14 days prior to installation. All doors
and windows must be installed. All water drainage must direct
away from the foundation, with all gutter and downspouts in place.
Tap the block parallel to the flooring. Do not stand and swing the
hammer perpendicular to the flooring. For best results simply slide
the hammer across the foam underlayment into the tapping block,
using firm strokes.
Basements and crawl spaces must be dry and well ventilated.
Adequate ventilation, and 6-8 mil black polyethylene film is
essential to divert moisture away from the framework, subfloor and
flooring. Check for moisture (see requirements).
Only use the recommended tapping block to install Tarkett Wood
Floors Floating Wood Floors. Cut pieces of plank, or other makeshift
tapping blocks can damage fit of the tongue, or the face of the
plank?
Never install your Tarkett Wood Floors flooring in a full bath.
Do not use flooring planks or stair nosing strips to build stair
treads. Stair nosing pieces are designed to transition the floor to a
down-step or set of stairs, not for individual stair construction.
INSTALLERS–Advise your customer of the following:
Varying levels of humidity and temperature will affect the
performance and appearance of Wood Flooring. Care should be
taken to control the environment the floor is exposed to. Heating
season brings low humidity (dry air) that can lead to shrinkage and
cracks in the wood floor. Non-heating season brings high humidity
The use of putty to fill small gaps should be considered normal in
wood floor installation.
Always install from various boxes to ensure accurate color and

(humid/wet air) that can lead to expansion, cupping, or buckling of
the wood floor. To protect your investment and to assure long
lasting satisfaction we recommend that the Relative Humidity be
kept at 35%-55% year round. Problems arising from lack of
environmental control inside the building the floor is installed in is
not covered under the warranty.
NOTE:
requirements chart below to determine installation requirements.)
Subfloor requirements for wood type subflooring is a preferred 3/4”
or thicker plywood or OSB rated underlayment with a maximum
19.2 inch o.c. joist span. Existing wood flooring, or solid plank T&G
is also acceptable. The wood subfloor must be securely fastened
before installing your new wood floor. Be sure to check that your
subflooring material is dry, and secured with a fastener every 6”
along the floor joist to avoid squeaking, and potential gapping of
the attached wood floor. The maximum allowance for both
deviation and deflection is not to exceed 3/16” per 10’ span.
Installing 5” widths adds to dimensional stability
of flooring. Installing 3” widths is approved also.
Helpful Hints:
1) Start by installing the pre-cut planks along the wall following
the directions listed above. Be sure to allow for expansion
around the perimeter of the flooring with the use of wedges.
Guidelines for expansions space are the thickness of the
product being installed.
2) Lay the planks along the chalk line, being sure that the floor
is installed absolutely straight. Use the Tark Tool to engage
the sides and end joints of each successive plank. The use
of putty to conceal small gaps should be considered
normal in wood flooring installation.
3) After the initial 3 rows are installed, re-check for squareness,
and secure all wedges. Do not install pieces less than 9” in
length. End joints should be staggered a minimum of 6”
between end joints of adjacent row.
4) Begin the next row with the leftover piece from the row
before. Be sure not to visually repeat the end joints
throughout the installation. Continue installing the floor
across the room, being sure each board is placed in position
and fully engaged as the glue becomes more difficult with
time, and will permanently bond in one hour.
5) Doorjambs can be removed and replaced, however it is much
easier to undercut them. Use a leftover piece of the plank as
a guide to mark the bottom of the doorjamb, and use a fine
tooth saw to make the cut, allowing the foam underlayment
as well. The installed plank should slide easily under the
doorjamb with no restriction.
6) Installing the last row:
Most often the last row does not fit in width. When this
occurs, follow this simple procedure: Lay a row of boards,
unglued, tongue toward wall, directly on top of the last
installed row. Take a short piece of floating floor with the face
down and the tongue against the wall. Draw a pencil line
along the groove side of the small plank, moving down the
wall. The resulting line gives the proper width for the last
row, which when cut, can be wedged into place using the pull
tool. Make sure when the installation is complete that all
wedges are removed, and the expansion gap is covered with
the appropriate moldings. Always attach trim work to the wall
or other vertical object, never to the hardwood.
7) Maintaining the floor:
Protect the floor with fabric type floor protectors such as felt
back pads under all furniture.
8) Place protective mats under chairs with wheels, by entrance
areas, and in high traffic areas. Use only Tarkett Wood Floors
or other approved cleaners. Never use oil base or ammonia
based cleaners on your Tarkett Wood Inc. hardwood flooring.
9) Minor damage can be repaired with Tarkett Wood Inc. TouchUp Kits.
Concrete subflooring must be cured to a hard, dry, non-powdery
finish. The maximum deviation in the slab cannot exceed 3/16” per
ten-foot radius for floating Engineered. Dry sand may be used to fill
depressions less than 1/4” in depth. If depressions are greater than
1/4” use a Portland base leveling compound.
NOTE:
Subfloor irregularities that cause wood flooring
installation to develop movement or hollow spots
between the subfloor and the wood flooring, are
NOT the result of manufacturing defects and are
not covered by Tarkett Wood Inc. warranties!
For concrete subfloors, when Tarkett Wood flooring will be
installed directly to the subfloor, one of the following moisture
tests must be performed and documented prior to installation.
In any situation when test results indicate moisture levels
exceeding the guideline for that test D O N O T I N S T A L L T H E
F L O O R I N G. No warranty coverage will apply.
Subfloor Moisture Requirements
Calcium Chloride test (maximum 3.0 pounds)
Tramex Moisture Meter (maximum reading of 4.5)
Delmhorst G-40 Moisture Meter (reading of green/dry)
Mat Test (Visual Condensation)
New wood type subfloors should also be checked for moisture
using a reputable manufacturers moisture meter, designed for
use with flooring manufacturers. In general wood or plywood
subflooring should not exceed 14% moisture content, with a
maximum moisture variance not to exceed 4” difference
between the flooring and subfloor.
Radiant Heat Subfloors (Oak, Cherry and Walnut only)
• First lay 6 mil plastic sheeting should be loose laid with
seems overlapped 8” and lapped up the wall 4” all the way
around the room. This can be trimmed off after moldings are
installed. Then roll out foam butting edges.
• Maximum subfloor temperature should not exceed 80°F.
• Heating pipers must be covered with 1-1/4” concrete or
minimum 1/8” below bottom side of plywood subfloor. In
addition, heat transfer plates or insulation boards must be
under pipes.
• Heat system must be operated at normal living conditions for
a minimum of 14 days before installing flooring. 1-2 days
before flooring is laid, turn heating system off (at time of
installation subfloor must be 64°-68°F). Bring heat up to
normal temperature over 3-4 days.
• Room temperature must not vary more than 15° from season
Subfloor Requirements
The subflooring must be flat, firm, structurally sound, clean and dry
prior to installation. Test for moisture. If high moisture levels are
found, do not lay the floor. (Refer to subfloor moisture

Before starting to glue planks, dry lay (no glue used) a trial layout
of the first two rows of flooring. Working from left to right, install
planks so that the tongue faces out. Leave a minimum of expansion
space the thickness of floor that is being installed, between flooring
and wall. When reaching the end of the first row, cut the plank as
necessary to fit. (An easy way to mark the last plank in the row is
to place the plank in position with the side tongue against the side
tongue of the previously laid plank and the end of the plank
against the spacing wedge. Mark across the plank with a pencil and
cut along this line).
As part of your subfloor preparation, remove any base, shoe
moldings and interior thresholds. These can be replaced after the
floor has been installed. Undercut doorjambs to allow for your
expansion gap, and avoid difficult scribe cuts. This can be easily
done by using a small piece of the flooring as a guide for your
handsaw.
Tools & Materials Needed
Pencil
Measuring Tape
Safety Glasses
Hammer
Tarkett Wood Adhesive
3M Blue Tape
6-8 Mil Poly Plastic Sheeting
Insert spacers around all vertical walls every 8” apart to maintain
the expansion space between the flooring and the wall. Look for
walls that are not straight and use spacers as needed to keep
flooring square and straight.
Foam Underlayment
Table Saw or Chop Saw
Jamb Saw (Hand or Power)
Tapping Block
Pull Tool
Spacers
Your local retailer can help you with the items listed above.
Job Preparation
Remove all doors and shoe moldings. undercut all door casings
1/16” higher than the thickness of the flooring and underlayment to
be installed. Place a scrap piece of the flooring and sheet of
underlayment against the door casing to act as a guide and cut the
door casing with a hand or power jamb saw (set to correct height).
Be sure subfloors are sound and dry and level within the
recommended 3/16” in 8 linear feet.
Apply glue in the groove of each plank as you install. Begin 2” from
the end and fill the groove completely in 6” lengths, skipping 6”
and repeating the length of the board. Fully glue the end joint. It is
very important to fill the groove to its full thickness. This will
ensure proper transfer to the tongue of the adjoining planks.
Failure to follow proper glue schedule will void all warranties.
After deciding the direction in which the planks run, measure the
width of the room (the dimension perpendicular to the directions of
the flooring). The last row of the flooring should be no less than 11/2” wide. If it is less we recommend cutting the starter row
narrower. This will require extra cutting, but it will make the rest of
the installation easier and faster.
NOTE:
Planks installed parallel to the longest wall will
accent the floor best.
Racking the Floor
This process is essential to achieve a random appearance. Start by
either using random length planks found in the cartons or by
cutting four to five planks in random lengths, differing by at least
6” minimum end joints on all adjacent rows. Randomly install
different lengths to avoid a patterned appearance. Never waste
materials; the ends (if over 8” in length) cut from starter rows
should be used at the opposite side of the room to complete rows
or used to start the next row.
Tarkett Wood Floors’ Floating Wood Floors can be installed above
grade, on grade, or below grade. When installing over concrete or
below grade a moisture barrier of 6-8 mil plastic sheeting is
required. Loose lay the sheeting with the seams overlapped 8
inches, and lapped up the wall 4 inches. The plastic can be
trimmed at the walls after the molding is installed.
Installing the Floor (Floating Method)
3” and 5” width (minimum 3/8” thick) Tarkett Wood Inc.
Engineered floors may be installed using the floating method of
installation.
Once the subfloor preparation is complete, and the 6-8 mil plastic
sheathing (if required) you are ready to install the foam
underlayment. Once you have determined the direction the floor
will run, install the foam in the same lengthwise direction you plan
to install the flooring. Then roll the foam out, butting the edges to
ensure they do not overlap. For foam with plastic sheeting
attached, butt the foam.
When choosing the floating method for Engineered, the subfloor
must be flat to within 3/16” per 10 ft. radius. Tarkett Wood does
not warrant movement or flexing of the floor when using the
floating method. Whole unit or individual pieces with slight
movement should be considered normal, and provides comfort
under foot.

Instruction No. 11
Install Underlayment
To provide a moisture barrier for floors on concrete or below grade,
install 6 mil poly plastic sheeting, overlapping edges 4” and seal
seams with duct tape. Install 1/8” foam underlayment on top of
plastic sheeting.
the last row which when cut can be wedged into place using a
tarktool. Be sure that when the installation is finished the wedges
are removed and the expansion is covered with the appropriate
Tarkett Wood moldings. Always attach the trim to the wall or
vertical object and never to the installed floor.
When the decision is made on the direction the planks will run, be
sure to allow for expansion (thickness of floor) around the
perimeter of the room. Begin by snapping a chalk line 5” plus
expansion space off the starting wall. If the starting row is out of
square, it is recommended that the first row of boards be scribed
to allow for expansion, and a straight working line. Use wedges to
secure the planks during installation at both the side and ends of
each plank. Always work with the tongue facing away from the
starting wall.
Stagger a minimum of 6 inches between end joints of adjacent
planks (no less than 9” in length). End joints should not repeat
visually across the floor. The floor can be installed in successive
rows, or with the stairstep approach. We recommend using the
stairstep method to ensure a tight fit for the first few rows, and
limiting board separation during initial set-up. Always use a random
pattern to begin the installation:
Now that your Tarkett Wood Inc. floor has been installed you
should take every precaution to keep it beautiful for years to come.
Please refer to the maintenance guide for proper care.
Example: begin by using a half plank to start the first row a whole
plank for the second row and a quarter plank for the third row.
Install in numeric order as shown in picture. (Before cutting starter
pieces for the first row, always be sure that the plank size being
installed at the adjacent end of the row will be a minimum of 6
inches.) To ensure a random pattern, the center plank should be
longer than the first or third plank when laying the first row.
Installing the Last Row:
Most often the last row does not fit in width. When this occurs,
follow this simple procedure. Lay a row of boards unglued, tongue
toward the wall directly on top of the last row installed. Take a
piece of the engineered floor with the face down and the tongue
side against the wall. The resulting line gives the proper width for
