Caution: Wood Dust

Cutting, sanding or machining wood products produces wood dust. While wood

products are not hazardous under the OSHA Hazard Communication Standard (29 CFR

1910.1200), the International Agency for Research on Cancer (IARC) and the State of

California have classified wood dust as a human carcinogen.

Precautionary Measures: Airborne wood dust can cause respiratory, skin and eye irritation.

Power tools should be equipped with a dust collector. Use an appropriate NIOSH-designated

dust mask. Avoid dust contact with skin and eyes.

First Aid Measures in case of irritations: In case of irritation flush eyes with water. If needed

seek medical attention. If dermatitis occurs, seek medical attention.

PROPOSITION 65 WARNING: This product contains chemicals known to the state of California

to cause cancer.

WARNING! DO NOT MECHANICALLY CHIP OR PULVERIZE EXISTING RESILIENT

FLOORING, BACKING, LINING FELT, ASPHALTIC “CUTBACK” ADHESIVES OR OTHER

ADHESIVES.

Previously installed resilient floor covering products and the asphaltic or cutback adhesives used to install

them may contain either asbestos fibers and/or crystalline silica. The products in this carton DO NOT

contain asbestos or crystalline silica. Avoid creating dust. Inhalation of asbestos or crystalline dust is a

cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the

risk of serious bodily harm. Unless positively certain that the product is a non-asbestos containing material,

you must presume it contains asbestos. Regulations may require that the material be tested to determine

asbestos content and may govern the removal and disposal of material. See current edition of the Resilient

Floor Covering Institute (RFCI) publication “Recommended Work Practices for Removal of Resilient Floor

Coverings” for detailed information and instructions on removing all resilient covering structures.

IMPORTANT HEALTH NOTICE FOR MINNESOTA RESIDENTS ONLY: These building materials emit

formaldehyde. Eye, nose, and throat irritation, headache. Nausea and a variety of asthma-like symptoms,

including shortness of breath, have been reported as a result of formaldehyde exposure. Elderly persons and

young children, as well as anyone with a history of asthma, allergies, or lung problems, may be at greater risk.

Research is continuing on the possible long- term effects of exposure to formaldehyde. Reduced ventilation

may allow formaldehyde and other contaminants to accumulate in the indoor air. High indoor temperatures

and humidity raise formaldehyde levels. When a home is to be located in areas subject to extreme summer

temperatures, an air-conditioning system can be used to control indoor temperature levels. Other means of

controlled mechanical ventilation can be used to reduce levels of formaldehyde and other indoor air

contaminants. If you have any questions regarding the health effects of formaldehyde, consult your doctor or

call your local health department.

INSTALLER / OWNER RESPONSIBILITY:

It is the responsibility of the installer and owner to ensure that job site environmental, sub-floor and

subsurface conditions involved meet or exceed all requirements as outlined in installation instructions

prior to installation. Manufacturer declines all responsibility for product performance or installation

failure due to sub-floor, substrate or environmental deficiencies or jobsite conditions.

All wood continually expands and contracts until it reaches moisture equilibrium with the environment

in which it’s installed. As with all wood flooring, expansion and contraction will be minimized if the

interior relative humidity is consistently maintained year round. Humidification and/or

dehumidification systems may be necessary to maintain your home environment to prescribed

relative humidity conditions.

The owner/installer assumes all responsibility for final inspection of product quality. Examine flooring

for color, finish, and style PRIOR TO INSTALLATION. If material is unacceptable, contact the seller

immediately. Wood is a natural product and contains characteristics such as variations in color, tone

and graining. Flooring is manufactured in accordance with industry standards, which allows

manufacturing and natural deficiency tolerances up to 5% of the total installation. Installer should

work from minimum of 3 cartons at the same time to ensure good color and shade blend. The installer

must use reasonable selectivity and hold out or cut off piece with deficiencies. Do not install

undesirable pieces. Flooring warranties DO NOT cover materials with visible defects once they

are installed. Installation is acceptance of product quality.

All work involving water or moisture (plumbing, masonry, painting, plastering) must be completed

prior to flooring being delivered. Building envelope must be complete and exterior doors and windows

installed. Exterior grading and gutter downspouts should be completed and permanent HVAC

systems in operation.

Precautions should be taken to protect floors from other trade work. Do not cover floors with

plastic, red rosin, felt or wax paper or previously used cardboard. Instead use a breathable

material such as clean, dry, plain uncoated cardboard or Kraft paper. Inks from printed

cardboard could damage the hardwood floor. The floor should be thoroughly cleaned before

covering to remove grit and debris that would damage the finish. The floor must be completely

covered to eliminate uneven ambering from exposure to UV light.

Permanent HVAC should be on and operational a minimum of 5 days and maintained between 65 –

75 degrees and a relative humidity of 35%- 55% prior to delivery, during, and after installation of the

flooring for the life of the product. If HVAC is not possible at time of installation the environmental

conditions must be at or near normal living conditions between 60 – 80 degrees and at the average

yearly relative humidity for the area.

Building interiors are affected by two distinct humidity seasons – Heating and Non- Heating. Care

should be taken to maintain humidity levels between 35-55% year round.

Heating season – Low Humidity, Dry. All heating methods create dry, low humidity conditions.

Humidifiers are recommended to prevent excessive shrinkage or gapping in wood floors due to

seasonal periods of low humidity.

Non-Heating Season and Coastal or Waterfront Areas – High Humidity, Wet During the non-

heating season proper humidity levels should be maintained by using an air conditioner or

dehumidifier.

Manufacturer warranties do not cover natural expansion and contraction which results in

separation between planks, or damage caused by excessively low or high humidity. Seasonal

gapping is not considered a manufacturing defect.

Purchase an additional 5% of flooring to allow for cuts and additional 10% if installing diagonally

WARRANTY NOTE: Installer should provide owner with one carton end label from product

installed along with the pre-installation moisture content readings for warranty purposes.

Owner should retain carton end label and copy of invoice with product style name and style

number for their records. Owner should retain excess flooring and store in a climate

controlled area for future repairs in the event flooring is damaged.

The use of stain, filler or putty for correction is considered a normal practice and a routine part of

installation.

PRE-INSTALLATION & JOB SITE CONDITIONS Do not install wood flooring until appropriate temperature and humidity conditions have been achieved. Flooring should be delivered and stored inside the HVAC controlled portion of the jobsite. Flooring should be stacked with at least a four inch (4”) airspace under the cartons. Remove any and all plastic wrap that may have been used to ship the material. Make certain that the room temperature is set to normal living conditions as described above.
PAGE 3
Direct Glue Installation: Make sure the floor covering materials are well bonded to the subfloor/underlayment with full spread adhesive and no more than two layers thick, not to exceed 3/16″ (5 mm). With approved wood/wood composite sub-floors, if vinyl or tiles are loose, broken, or in poor condition, install a 3/8″ (9.5 mm) approved sub-floor panel directly over the flooring materials. Clean the flooring materials as necessary to remove waxes, sealers or cleaning residues to allow a good adhesive bond.

MAINTENANCE Performance Core Engineered Hardwood Floors are very easily maintained. No wax, no mess. The best way to care for your new floor is to schedule routine maintenance which includes sweeping the entire floor at least once a week to remove dirt and debris that may scratch the floor. High traffic areas such as entrances, doorways, and traffic lanes will require cleaning more frequently depending upon of the amount of concentrated foot traffic.
