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 aect 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 aecting 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 suciently
ventilated. Remove any obstacles and make sure there is sucient ventilation—the crawl
space should have perimeter venting 1.5 sq. ft. per 100 sq. ft. of crawl space, except where local
builder codes dier. 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.
