Navarre Hardwood Flooring
Installation Instructions
You must read and understand these instructions
completely before installing your flooring. In the event these
instructions leave unanswered questions or if you would like additional
information, please contact the manufacture or us prior to beginning
installation.
Responsibility for the suitability of the flooring
for each individual installation cannot be assumed by the manufacture or
retailer, since neither has no influence on the installer's proper
application. Should an individual plank be doubtful as to appearance or
dimension the installer should not use this piece.
Any defect must be
reported directly to the manufacture or retailer immediately. The
manufacture will send a replacement in a timely manner.
NOTE:
The Manufacture and
retailer makes no warranty or guarantee of the quality of work performed
by a selected installer. The manufacture and retailer disclaims all
liability for imperfect installation of its product. The manufacture
pre-finished flooring is best installed over a wood subfloor using
staples/brads or glue. Navarre floors may be applied over in-floor
radiant heating systems in a floating installation. Recommended
equipment is the
Stanley Bostitch MARK III Flooring Nailer & Mark
III Foot Kit.
The foot kit is needed to adjust the thickness to fit the 5/8’’
dimension. Typical air pressure settings are 85 lbs. (However, these
settings may vary depending on the equipment being used). Proper use of
this equipment will render good results.
ACCLIMATION:
Navarre flooring must
be allowed to acclimate on-site a minimum of 72 hours in advance of
installation. Open each box and remove shrink-wrap completely. During
the acclimation period it is important that temperature and humidity
levels be maintained in accordance with those expected to exist after
installation. Optimum installation conditions are 70 degrees Fahrenheit
at 30 - 50% humidity.
SUBSTRATE PREPARATION:
Underlayment-grade plywood and man-made board substrates must be clean, level,
dry, and free of contaminants. Optimum results will be achieved through use of 3/4” CDX plywood substrate.
Fill any low spots with appropriate filler and sand any high spots. For
buildings with a raised foundation, install ground cover of 6 mil polyethylene sheets over
the earth in crawl space.
Concrete Substrate must be on or above grade. Concrete
is required to be sound, smooth, level and flat with a maximum variation of 1/8”
in 10’. Fill any low spots with appropriate filler and scrape any high spots.
Subfloor must be properly cured and tested for moisture content. Slab must be properly
cured. Flooring must not be installed if vapor pressure exceeds 3 lbs. per 1000
square feet in 24 hours using calcium chloride test method.
INSTALLATION:
Flooring should be square with the space, running
parallel to longest room dimension. A 1/2”
expansion space must be left around entire perimeter. It is important that the tongue & groove of
each plank fit together tightly at all seems and butt joints. Starter row must be held
firmly in place using either nails or wedging. Use of proper equipment will improve overall
quality of installation.
Nail Down Method: Flooring should be installed over a 15
lb Asphalt paper (roofing felt) or Red Rosin paper. Once starter rows are
secure, additional rows should be blind nailed using a professional quality
flooring nail gun. Excessive splitting or cracking of plank tongue can
result from use of improper equipment or incorrect equipment settings.
Holding nail gun at a 45-50 degree angle to face of plank, insert nails
directly above tongue.
Beginning a minimum of 2 inch from end of first plank,
space nails at 8 inch intervals. To prevent splitting, nails should not be
placed closer than 2 inch from either end of plank. Two inch long flooring nails
(cleats), or 2-inch, 15 gauge flooring staples with a ½ inch crown are
recommended.
Floating Method: Make sure subfloor is tested for
moisture content first and is properly prepared.
When using Natural Cork CorkShield underlayment, no
additional moisture barrier is necessary. If using an alternative 1/8” thick
pad and installing below or on grade, polyfilm is required.
Laying polyfilm: lay 6-mil polyfilm with seams
overlapped 8”. Fasten seams every 18-24” with duct tape. Run the outside edges of
film up perimeter of each wall 4”. Trim after flooring installation is
complete.
Laying pad: lay Natural Cork CorkShield or equivalent
underlayment by butting edges, not overlapping. Tape full length of the
seam with duct tape. Leave ½” space between pad and all walls and permanent
vertical fixtures.
Installing the floor: start first row with groove toward
wall. Glue end joints of first row by applying a small but continuous bead of
Eurobond®
D3 T&G
Adhesive or Franklin®
Titebond 2 PVAC glue to bottom side
of the groove.
Always leave at least a 3/8” expansion space between
flooring and all walls and vertical objects such as pipes and cabinets. Use
wood or plastic spacers during installation to maintain this expansion space.
Lay subsequent rows of flooring by applying glue to side and end joints and
fitting planks together with a tapping block. Remember to stagger end joints
from row to row at least 8” apart. Clean up any adhesive that is on the
face of the floor by using a damp rag. DO NOT allow adhesive to dry on the flooring face as it
is difficult to remove without damaging the finish.
In-floor Radiant Heat:
Regardless of season, radiant heat system should be
turned on and remain on for five days in
advance of installation. A radiant floor should not produce surface temperatures over 85 degrees
Fahrenheit. Continue to operate radiant heat system after
installation.
*This type of installation requires a specific
construction of the plywood subfloor and the installer for such
must be familiar with the NWFA recommendations.
NWFA (National Wood Flooring Association) can be
reached at 800-422-4556 U.S, or 800-848-8824 Canada.
Engineered bamboo and hardwood flooring is
better suited for installation over floors with radiant heat.

NOTE:
Any wood flooring, including bamboo, will expand and contract in
response to changes in temperature and humidity. There should be no more
than a 2% maximum difference in moisture content between the subfloor
and surface flooring material. The amount of movement varies dependant
upon temperature, dimensional stability of the materials involved, and
moisture content of both the surface flooring and subfloor. Visible gaps
at seams and joints will vary seasonally.
