ATTENTION INSTALLERS

Sawing, sanding and machining wood products can produce wood dust. Airborne wood dust can

cause respiratory, eye and skin irritation. The International Agency for Research on Cancer (IARC)

has classiﬁed wood dust as a nasal carcinogen in humans.

Precautionary Measures: If power tools are used, they should be equipped with a dust collector. If high dust

levels are encountered, use an appropriate NIOSH-designated dust mask. Avoid dust contact with eye and skin.

First Aid Measures in Case of Irritation: In case of irritation, ﬂush eyes or skin with water for at least

15 minutes.

CAUTION: WOOD DUST

I. GENERAL INFORMATION

Owner/Installer Responsibility

Beautiful hardwood ﬂoors are a product of nature and therefore, not perfect. Our hardwood ﬂoors are manufactured in

accordance with accepted industry standards, which permit grading deﬁciencies not to exceed 5%. These grading

deﬁciencies may be of a manufacturing or natural type. When ﬂooring is ordered, 5% must be added to the actual square

footage needed for cutting and grading allowance (10% for diagonal installations).

• The owner/installer assumes all responsibility for ﬁnal inspection of product quality. Inspection of all ﬂooring should

be done prior to installation. Carefully examine ﬂooring for color, ﬁnish and quality before installing it. If material is not

acceptable, do not install it. Contact the seller immediately.

• Prior to installation of any hardwood ﬂooring product, the owner/installer must determine that the job-site environment

and the sub-surfaces involved meet or exceed all applicable standards. Recommendations of the construction and

materials industries, as well as local codes, must be followed. These instructions recommend that the construction

nd subﬂoor be clean, dry, stiff, structurally sound and ﬂat. The manufacturer declines any responsibility for job failure

resulting from, or associated with, subﬂoor and substrates or job-site environmental deﬁciencies.

• Prior to installation, the owner/installer has ﬁnal inspection responsibility as to grade, manufacture and factory ﬁnish.

The installer must use reasonable selectivity and hold out or cut off pieces with deﬁciencies, whatever the cause.

Should an individual piece be doubtful as to grade, manufacture or factory ﬁnish, the installer should not use the piece.

• Use of stain, ﬁller or putty stick for touch-up and appropriate products for correcting subﬂoor voids is accepted as part

of normal installation procedures.

Subﬂoor Conditions

• CLEAN – Subﬂoor must be free of wax, paint, oil, sealers, adhesives and other debris.

• LEVEL/FLAT – Within 3/16″ in 10′ (5 mm in 3 m) and/or 1/8″ in 6′ (3 mm in 2 m). Sand high areas or joints. Flatten

low spots with a maximum 6 layers of 15# builders felt, plywood or shims (not leveling compounds).

• DRY – Check and document moisture content of the subﬂoor with the appropriate moisture test. Install moisture

retardant materials if needed or desired. (See plank installation note.) Moisture retardant materials must meet

minimum perm standards of 3 > 50 ASTM D4869-88, Type I or F.S. UU-B-790a, Type I, Grade D, Style 1a. Most asphalt

saturated papers, #15 felt or Grade D kraft paper meet this perm rating. Common brown kraft builder paper and red

rosin generally do not qualify as vapor retarders. Concrete subﬂoors must be a minimum of 30 days old before testing

begins.

• STRUCTURALLY SOUND – Nail or screw any areas that are loose or squeak. Wood panels should exhibit an adequate

fastening pattern, glued/screwed or nailed as system requires, using an acceptable nailing pattern. Typical: 6″ (15 cm)

along bearing edges and 12″ (31 cm) along intermediate supports. Flatten any swollen edges as necessary. Replace

any water-damaged, swollen or delaminated subﬂooring or underlayments.

NOTE: Avoid subﬂoors with excessive vertical movement. Optimum performance of hardwood ﬂoor covering products

occurs when there is little horizontal or vertical movement of the subﬂoor. If the subﬂoor has excessive vertical

movement (deﬂection) before installation of the ﬂooring, it is likely it will do so after installation of the ﬂooring is

complete.

Subﬂoors with Radiant Heat

NOTE: Do not install this product over Subﬂoors with Radiant Heat.

Tools & Accessories Needed

NOTE: IT IS EXTREMELY IMPORTANT TO USE THE PROPER ADAPTERS, FACE PLATES, AS WELL AS STAPLES

OR CLEATS. IMPROPER FASTENERS, MACHINES AND AIR PRESSURE CAN CAUSE SEVERE DAMAGE. THE

MANUFACTURER OF THIS FLOORING PRODUCT IS NOT RESPONSIBLE FOR DAMAGE CAUSED BY USE OF

IMPROPER TOOLS OR MISUSE.

• Chalk line & chalk • Recommended hardwood ﬂooring cleaner • Nail set • Tape measure • Hammer

• Electric power saw • NIOSH-designated dust mask • Electric drill and bits

• Compressor and hose w/in-line regulator for pneumatic tools

• “Blind’ fastening machine for 3/4″ (19 mm) ﬂooring (see note below)* w/1-1/2″ or 2″ (4–5 cm) fasteners

• Pneumatic ﬁnish nailer with 1-1/ 2″ or 2″ (4–5 cm) nails • 6-8d ﬁnish nails

• Moisture meter (wood, concrete or both) • Broom • Hand saw or jamb saw

• Eye protection • Transition and wall moldings

• Urethane construction adhesive for ﬂoors wider than 4″ (10 cm)

*Use a “Blind” nailing machine designed for installing 3/4″ (19 mm) hardwood ﬂooring

using staples or cleats. The nailing machine MUST HAVE a protective foot attachment to

prevent edge bruising and ﬁnish damage. Use one of the following: Stanley Bostitch (multiple

models) with M-4 foot, Powernail (multiple models) with NailerShoe, Primatech (multiple

models) with Trak-Edge.

III. SUBFLOOR/UNDERLAYMENT REQUIREMENTS

NOTE: Solid hardwood ﬂooring can be fastened to most existing ﬂooring materials providing they can be penetrated with the

fastener and the subﬂoor/underlayment materials meet or exceed the recommended subﬂoor/underlayment requirements.

Laminated rosin paper or 15# builders felt (tar paper) acts as a moisture retarder and may be used to reduce movement caused

by changes in subﬂoor moisture, thereby reducing cupping and warping. (This is especially helpful over crawl spaces and

basements.) In addition, the use of these materials can give the ﬂooring a more solid feeling, reduce sound transfer, prevent

noise caused by minor irregularities and debris, and make it easier to slide the hardwood together across the surface of the

subﬂoor. Kraft paper may be used to make installation easier but DOES NOT serve any other purpose.

Wood Subﬂoors and Underlayment

General: The wood subﬂooring materials must not exceed 13% moisture content. Using a reliable wood moisture meter,

measure the moisture content of both the subﬂoor and the hardwood ﬂooring to determine proper moisture content. The

difference between the moisture content of the wood subﬂoor and the hardwood ﬂooring must not exceed 4% for strip

and 3% for plank ﬂooring. When installing parallel to the ﬂoor joists it may be necessary to stiffen the subﬂoor system

by installing an additional minimum of 3/8″ (9.5 mm) approved wood underlayment. Applicable standards and

recommendations of the construction and materials industries must be met or exceeded.

NOTE: As ﬂooring manufacturers, we are unable to evaluate each engineered joist/subﬂoor system. Spacing and spans,

as well as their engineering methods, are the responsibility of the builder, engineer, architect or consumer who is better

II. PREPARATION

Storage and Handling

Solid hardwood ﬂooring should be stored in the environment in which it is expected to perform. Deliver the materials to

an environmentally controlled site. The wood subﬂooring materials must not exceed 13% moisture content. Using a

reliable wood moisture meter, measure and document the moisture content of both the subﬂoor and the hardwood

ﬂooring to determine proper moisture content. The difference between the moisture content of the wood subﬂoor and

the wood ﬂooring must not exceed 4% (3% for plank). Acclimate the hardwood ﬂooring on or off the job, as necessary,

to meet these requirements. Store in a dry place, being sure to provide at least a four-inch air space under cartons which

are stored upon “on-grade” concrete ﬂoors. Flooring should not be delivered until the building has been enclosed, with

windows and doors in place, and until cement work, plastering and all other “wet” work is completed and dry. Concrete

should be at least 60 days old.

Job-Site Conditions

• The building should be enclosed with all outside doors and windows in place.

All concrete, masonry, framing members, drywall, paint and other “wet” work

should be thoroughly dry. The wall coverings should be in place and the

painting completed, except for the ﬁnal coat on the base molding. When

possible, delay installation of base molding until ﬂooring installation is

complete. Basements and crawl spaces must be dry and well ventilated.

• Exterior grading should be complete with surface drainage, offering a minimum

drop of 3″ in 10′ (7.6 cm in 3.05 m), to direct ﬂow of water away from the

structure. All gutters and downspouts should be in place.

• Solid hardwood ﬂooring may be installed on- or above- grade level. Do not

install in full bathrooms. Installation of a suitable subﬂoor is required over

concrete.

• Crawl spaces must be a minimum of 18″ (46 cm) from the ground to the

underside of the joists. A ground cover of 6–20 mil black polyethylene ﬁlm is

essential as a vapor barrier with joints lapped 6″ (15 cm) and sealed with

moisture resistant tape. The crawl space should have perimeter venting equal

to a minimum of 1.5% of the crawl space square footage. These vents should

be properly located to foster cross ventilation (Figure 1). Where necessary, local

regulations prevail.

• Permanent air conditioning and heating systems should be in place and operational. The installation site should have

a consistent room temperature of 60–75° F (16–24° C) and humidity of 35–55% for 14 days prior to and during

installation and until occupied.
