Installation Instructions

For 3/4" Mohawk Solid Hardwood oors

Solid hardwood flooring can be installed over most properly prepared subfloors, making them suitable for installation on or above grade levels where moisture

conditions do not exist. We continuously make technological advancements that improve product performance or installation techniques and methods.

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 irritation flush eyes with water. If needed seek medical attention. If dermatitis occurs, seek medical attention.

To request Safety Data Sheets, call 888-387-9881, option 3.

WARNING: Drilling, sawing, sanding or machining wood products can expose you to wood dust, a substance known to the state of California to cause

cancer. Avoid inhaling wood dust, or use a dust mask or other safeguards for personal protection. For more information, visit: P65Warnings.co.gov/wood

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.) Avoid creating dust. Inhalation of such 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 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.

Installer/Owner Responsibility

It is the responsibility of the installer and owner to ensure that job site environmental, subfloor 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 subfloor, substrate or environmental deficiencies or jobsite conditions.

Manufacturer requires solid hardwood products acclimate for a minimum 72 hours prior to installation. Additional time may be required for

5" wide or wider products as determined by moisture content. Acclimation allows flooring to achieve equilibrium moisture content (EMC) with the

installation environment. 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 climate control is consistently maintained year round. This is especially important

with tropical species because denser woods experience more significant shrinkage in low moisture or low humidity environments.

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 operational.

Installation Instructions For 3/4" Mohawk Solid Hardwood floors 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. Inks from printed cardboard could stain the hardwood floor. Instead use a breathable material such as clean, dry, plain, uncoated cardboard or Kraft paper. The floor should be thoroughly cleaned before covering to remove grit and debris that could damage the finish.

Installation Instructions For 3/4" Mohawk Solid Hardwood floors Subfloor Preparation On or Above Grade Only We recommend three types of subfloors: plywood or OSB, solid wood planks measuring 1" x 6" or larger, or 2" x 4" sleepers. Each subfloor type requires separate installation guidelines.

Installation Instructions For 3/4" Mohawk Solid Hardwood floors Wood Subfloor Moisture Content Test both wood subfloor and wood flooring for moisture content using a reliable pin type moisture meter. The subfloor material must not exceed 12% moisture content. The difference between the moisture content of the wood subfloor and the hardwood flooring must not exceed 4%. For hardwood products greater than 3" wide, the moisture content of the wood subfloor and hardwood floor should not differ more than 2%.

Installation Instructions For 3/4" Mohawk Solid Hardwood floors Helpful Hints • Use solid flooring only on or above ground level. • Make sure mechanical fastener is approved for use in OSB if plywood is not used as a substrate. • Lay out several cartons to check quality and grading, and “rack” or stagger the end joints in random lengths. • Leave 3/4" at all perimeter walls and vertical structures to allow for expansion. • The mechanical fastener cannot be used on the first and last few rows.

Installation Instructions For 3/4" Mohawk Solid Hardwood floors Step 2 – Install first row • Using the string as a straight edge, lay the first row of flooring in place with the tongue facing the center of the room. Leaving a 3/4" gap at the wall, pre-drill and face nail using 10D nails. Continue nailing the entire length of the room. • Leave a 3/4" expansion gap at each end. Set nails and fill holes with matching putty. Remove string and nails.

Installation Instructions For 3/4" Mohawk Solid Hardwood floors Final Touches Install the proper trim molding at the doorways to achieve the transition and along the walls to cover expansion gap and the edges of any gaps along the wall due to irregularity. Complete the job using wood filler that coordinates with the installed hardwood flooring to fill any gapping along the joints or areas where brad nails were used in the trim or the flooring. Sweep the floor to remove any particles that could scratch it.

Installation Instructions For 3/4" Mohawk Solid Hardwood floors Transition Mats Transition mats should be used at all exterior entrances to minimize tracked-in soil and reduce moisture during inclement weather. Ideally, the purchase of two sets of transition mats for each exterior entrance will allow a fresh one to replace the soiled one during routine weekly cleaning. This will prevent the transition mat from becoming a soil source.
