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 affect 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 affecting 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 sufficiently ventilated. Remove any obstacles and make sure there is sufficient ventilation—the crawl space should have perimeter venting 1.5 sq. ft. per 100 sq. ft. of crawl space, except where local builder codes differ. 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. www.Pergo.com 55–85ºF (13–30ºC) <8 lbs MVER or <90% RH
