Pergo Extreme Installation Instructions
Pergo Extreme
Preparation
We recommend placing a single order for all cartons required for a commercial flooring project.
1. Always store and transport Pergo Extreme Luxury Vinyl Flooring on a flat surface in neat stacks
to prevent warping. Never store the boxes upright or in moist, dusty rooms or in places with
extreme temperatures. Pergo Extreme Luxury Vinyl Flooring must be acclimated in the room of
installation between 55-85°F (13-30°C) for a period of at least 48 hours before installation. This
temperature range should be maintained during installation and for at least 24 hours after the
installation is complete.
2. The type of subfloor, its quality and its preparation will greatly aect the results of the final
installation. If the subfloor is not suitable for the installation of Pergo Extreme Flooring,
then necessary corrections must be made. Contact your Pergo Extreme Flooring dealer
for assistance as needed. Be aware that unevenness and imperfections in the subfloor may
translate through the planks, negatively aecting the final appearance of the installation.
It is possible to install Pergo Extreme Flooring over many existing floor coverings, providing
it is stable and firmly fixed. Existing flooring cannot be soft, damaged or loosely laid. Please
remove carpet, needle felt, cushion vinyl, floating laminate and floating hardwood. You may
install directly over ceramic tiles, PVC, VCT, glued laminate, glued hardwood and fixed wooden
boards, provided they are installed over a wooden subfloor.
3. When installing over a wooden subfloor, first remove any existing floor covering. Ensure the
subfloor is free of mold and mildew. Ensure the subfloor is level and nail down any loose
boards. Repair the wooden subfloor as needed by applying an appropriate underlayment
board or leveling compound. The underlayment boards must be stapled according to
manufacturer’s recommendations. The crawl space under the plank floor must be suciently
ventilated. Remove any obstacles and make sure there is sucient ventilation—the crawl
space should have perimeter venting 1.5 sq. ft. per 100 sq. ft. of crawl space, except where local
builder codes dier. The moisture content of the wood subfloor must not exceed 12%. A 6 mil
vapor barrier covering all exposed soil in a crawl space must be used.
4. Make sure the subfloor is completely flat. Any joints of more than 1/8 inch (3 mm) in depth and
1/4 inch (6 mm) in width should be leveled using an appropriate primer and leveling compound.
5. The moisture content of the concrete subfloor must be less than 90% relative humidity (RH
test, ASTM F2170) or less than 8 lbs moisture vapor emission rate (MVER test, ASTM F1896).
Always measure, record and keep moisture content results.

Preparation (cont.)
6. Any unevenness greater than 3/16" in a 10' radius (5mm in 3m) must be leveled. Use an
appropriate leveling compound and use primer or sealer if recommended by supplier. In some
cases, the use of an underlayment may eliminate the need for additional leveling of subfloor.
7. Floor heating systems (hydronic or electric) that are built into the cement subfloor may be
used with Pergo Extreme Flooring if a constant room and floor temperature of 65 to 85°F
(18 to 30°C) can be maintained during acclimation and installation and for 48 hours after
installation is complete. For health and safety reasons, a maximum floor surface temperature
of 82°F (27°C) must be maintained. Separate rooms with and without radiant floor heating
or rooms with dierent temperature controllers using a transition profile. We recommend
Mohawk RevoFit™ moldings, following manufacturer’s installation guidelines and utilizing a 1/4
inch (6 mm) expansion gap 5/8 inch (16mm) for areas that will be exposed to temperatures
greater than 85°F (30°C) to allow expansion and contraction of the subfloor.
8. Make sure that the subfloor is dry, flat, stable, clean and free from debris, grease and
chemical substances. If needed, scrape o and clean up old adhesives. Prior to installation,
carefully remove all debris, sweep and vacuum. Repair surface imperfections and cracks. We
recommend removing existing base trim and installing new moldings after installation of Pergo
Extreme flooring is complete.
9. The following standard tools are needed: utility knife, tape measure, safety glasses, chalk line,
speed square, tapping block, circular saw, gloves and a pencil. In addition to the standard tools,
we recommend having a pull bar and a carpenter’s square available.
The use of any accessories other than Pergo Extreme accessories may cause damage
to your Pergo Extreme flooring. In such cases, the warranty provided by Pergo will be
void. Therefore, we advise using only Pergo Extreme accessories, which have been specially
designed and tested for use with your Pergo Extreme flooring. The RevoFit™ molding can be
used as a T-molding or reducer, and track may be stapled to wooden subfloors or glued, using
a moisture-cured polyurethane based adhesive and following manufacturer’s instructions. Do
not glue any transition strips or moldings directly to the floor.
10. Visually inspect all planks before and throughout installation in optimal lighting. Unacceptable
planks should be discarded or, when possible, used as cut pieces to start or finish rows after
removing the defective portion of the plank.

Pergo Extreme Installation Instructions
Installation
1. During installation, blend the planks by working out of multiple cartons to avoid laying too
many identical lighter or darker panels adjacent to one another. For optimal results, it is best
to fit the panels in the direction of the longest wall and parallel to the light source in the
room. Avoid installing plank flooring using the “brick” method of staggering. It is best to use a
random stagger of at least 8 inches (20 cm).
2. Measure the room before you start installing underlayment or flooring planks. Make sure that
the last row of panels is at least 3 inches (7.6 cm) wide when finishing the installation. We
recommend snapping a chalk line to ensure a perfectly straight installation.
3. Pergo Extreme flooring has been designed for floating installations in indoor areas including
three season environments with or without underlayment inclusive of sunrooms and solariums
with ambient temperatures ranging between 0 and 140°F (-17 and 40°C). Please contact your
flooring dealer or Mohawk Technical Services if you have any questions.
4. If you choose to use underlayment, install it simultaneously with the floor installation. We
recommend Mohawk ActiveSound underlayment, which helps ensure joint integrity, reduces
sound, helps prevent indentation, and insulates and helps level the subfloor. Pergo Extreme
products with pad attached cannot be installed over separate underlayment.
5. Begin in the left corner of the room. Start the first row with a whole plank. Cut o the long side
tongue (end and edge) for the first panel. Position the cut edges adjacent to the wall.
6. Fit the plank with cut side against the walls. Make sure that you leave an expansion space of 1/4
inch (6 mm) [5/8 inch (16mm) for areas that will be exposed to temperatures greater than 85°F
(30°C)] between the plank and the wall, using spacers as needed.
7. Cut using a circular saw or reciprocating jigsaw.

Installation (cont.)
8. Turn the long side of the first panel of the second row into the already secured panel in the first
row at an angle of 20 to 30°. Move the panel to be fitted slightly up and down; at the same
time, exert some forward pressure. The panels will click together.
9. Then slide the third plank together horizontally. Slightly lift the plank to be
installed by holding your hand underneath. Push the short side joint down
gently with your thumb, moving from the inner corner towards the outside
until you hear a “click”. Ensure the short side ends are closed by knocking
gently on the short side click connection with the palm of your hand or
tapping block.
Next, connect the panels of the first two rows on the short sides.
10. Check the expansion space to ensure it is at least 1/4 inch (6 mm) [5/8 inch (16mm) for areas
that will be exposed to temperatures greater than 85°F (30°C)] and make sure the first two
installed rows are perfectly straight. A chalk line can help ensure the installed planks are
aligned. Adjust the straightness of your floor as necessary.
11. Continue installation row by row toward the opposite side of the room. Always check each joint
to ensure a good locking connection before continuing to the next plank. Press down gently
with your thumb on top of every short end joint to ensure a good locking connection.
An expansion space of 1/4 inch (6 mm) [5/8 inch (16mm) for areas that will be exposed
to temperatures greater than 85°F (30°C)] around the perimeter of the room should
be maintained; this same expansion space should be maintained when using transition
moldings. Otherwise, there is no need for additional expansion space within or between
rooms.
Finishing
You may walk on your new Pergo Extreme floor immediately after installation.
1. Inspect the final surface of the installed floor. Install base molding to the wall. Never attach the
base to the floor itself. In places where profiles or base cannot be installed, fill the expansion
space with silicone.

Finishing (cont.)
2. When the new flooring meets a threshold or a doorway, we recommend undercutting the door
jamb. To secure the right cut, turn a plank upside down and place it on the floor up to the door
frame. Then place a handsaw flat against the plank and simply cut through the frame. Remove
the cut-out piece and vacuum away debris. You can now secure the plank on the long side at
the side of the door jamb. Use an installation tool pull bar to securely join the long and
short joints.
3. If it is dicult to tilt the planks (e.g. under radiators), use a pull bar installation tool to pull the
planks together.
4. In rows where there is a pipe, make sure the pipe falls exactly in line with the short side of two
planks. Select a drill bit with the same diameter as the pipe plus 1/2 inch (13 mm). Click the
planks together on the short side and drill a hole centered on the joint between the two planks.
Then install the planks.
5. For a double pipe, drill a hole equivalent to the diameter of the pipe plus 1/2 inch (13 mm) at
each of the marked points. If located on the long side of the plank, make a 45° cut from each
hole to the edge of the plank.
Then, using an appropriate glue along the cut edges of the piece you cut out,
glue the piece in place. Be sure no glue comes between the cut-out piece and the
subfloor.
Maintenance
For full care and maintenance instructions for residential and commercial
applications, please visit www.mohawkflooring.com.
1. Use a vacuum cleaner suitable for hard surface flooring (with no moving parts
and without rotary beater bars) to clean your Pergo Extreme floor. Your Pergo
Extreme floor can also be cleaned with a damp or wet mop.
Never use a steam cleaner on your Pergo Extreme floor.
2. Remove spills from the floor immediately.

Maintenance (cont.)
3. Protect the floor from furniture and chair legs by using felt pads and coaster
protectors. Ensure chairs with castors have suitable soft rubber wheels. Replace
hard or plastic castors with soft wheels designed for a vinyl floor and/or use a
suitable desk mat.
Never drag heavy items of furniture over the floor, always lift instead. Make sure furniture
legs have a large surface area in contact with the floor and are axed with non-staining floor
protectors. The taller and wider the furniture feet are, the greater the disbursement of weight,
which helps avoid damage to the floor.
4. Ensure that the indoor room temperature is always
maintained between 0 and 140°F (-17 and 40°C).
Place non-rubber backed mats at all outside entrances to prevent dirt, grit and soil from being
tracked onto your floor. This will help keep the floor clean and extend the life of your floor.
Do not allow cigarettes, matches or other very hot items to contact the floor as this may
cause permanent damage. Also, prolonged contact with items made from rubber can cause a
permanent stain on the floor.
