Read all instructions completely and carefully before beginning any project. Final product inspection is the responsibility of the installer/owner prior to installation. Installer must use reasonable selectivity and hold out or cut off pieces with obvious defects, whatever the cause. Five percent (5%) must be added to actual square footage needed as allowance for cutting waste and errors in manufacturing. If an individual piece appears to be doubtful as to grade or manufacture, the installer should not use the piece of flooring. Installation implies acceptance of flooring.
As with all Hardwood manufacturers, if any questions arise that are not covered within our installation instructions, always refer to the National Wood Flooring Association (NWFA).

Caution: Wood Dust
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. -
Tools
The following tools will be helpful, if not necessary for proper
installation: moisture meter, mallet, table or circular saw,
chalk-line, tape measure, hammer, drill with 1/16” drill bit,
nailset, and jamsaw or handsaw. A good quality power nailer in
proper working condition will greatly speed installation. -
Job Site Conditions
In a new construction, hardwood flooring should be one of the
last items installed. All work involving water or moisture
(plumbing, acoustical ceilings, dry wall taping, etc.) should be
completed prior to wood flooring being installed. Heating and
air systems should be fully operating maintaining a consistent
room temperature at 16°C to 27°C (60-80° F) and a constant
relative humidity of 40 to 55%.Flooring should not be delivered until the building has been
closed in and cement work, plastering, painting and other
materials are completely dry. Concrete and plaster should be
cured and at least 60 to 90 days old. Check basements and
underfloor crawl space to be sure that they are dry and well
ventilated to avoid damage caused by moisture.For proper acclimation, flooring should be at the job site at
least 72 hours prior to installation or as long as necessary to
meet minimum installation requirements for moisture content.
Acclimation within a closed or sealed carton may not be
adequate due to lack of air movement, especially in dryer
climates. Please take appropriate measures to ensure proper
acclimation, which may Eastern Hardwood Installation
Instructions Page 1 of 8 Last Updated on 4/11/19 entail
removal of outer plastic wrapping or opening of cartons and
peeling back of interior plastic wrapping if packaged in
this manner. (Do not open the ends of cartons only, as this can lead to
tapered ends of individual flooring strips or planks).Handle with care. Do not stand on ends. Store flooring in a dry
place being sure to provide at least a four-inch air space under
and around cartons.Do not store directly on concrete or near outside walls. Cartons
should be placed in the installation area.The installation site should have consistent room temperature at
16°C to 27°C (60-80° F) and a constant relative humidity of 40
to 55% for a minimum of 5 days prior to installation of wood
flooring.Note: The moisture content of the subfloor and wood flooring
should be checked by an appropriate method. There should be no
more than 4% (2% on planks 3” and wider) moisture content
difference between properly acclimated wood flooring and
subflooring materials, taking into consideration normal living
conditions and equilibrium moisture content (EMC).IMPORTANT: ¾” solid flooring is for on or above grade
installation only. ¾” solid flooring cannot be installed over
radiant heat. -
Approved Subfloor Types
1.- APA approved ¾” or thicker exterior plywood.
2.- ¾” (23/32”) OSB on 16” center floor joists properly nailed.
3.- Concrete slab with additional approved wood sleepers and
screed system. (See NWFA’s guidelines)4.- Wood Floors (if installed at proper angle only).
5.- Resilient tile and sheet vinyl if installed over an above
mentioned and approved subfloor.6.- Particle board is not an acceptable subfloor.
-
Subfloor Must Be
Clean – scraped or sanded, swept, free of wax, grease, paint,
oil and other debrisSmooth/Flat – within 1/8” on 6’. Sand high areas or joints, fill
low areasStructurally Sound – nail or screw any loose areas that squeak.
Replace any damaged subflooring or underlaymentDry – an 8 to 10% moisture content is ideal and must never
exceed 13% prior to installation of wood flooring.Remember: All moisture testing must be before wood has been
acclimated 72 hours and job site requirements met.Wood Substrates: Test the moisture of the wood substrate using a
calibrated moisture meter approved for testing wood moisture
according to the meter manufacturer. The reading should not
exceed 13%, or read more than a 4% difference than moisture
content of products being installed. (maximum 2% for planks 3
1/4” and wider)Concrete Slabs (regardless of existing floor covering): Must
have a minimum of ¾” plywood installed as a screed/sleeper
system with a minimum of 6mil polyfilm vapor barrier secured to
the slab for solid hardwood to be nailed or stapled only.
Engineered may be glued directly to the concrete.All concrete subfloors must be tested for moisture content prior
to installation of the hardwood flooring. The moisture content
of the concrete subfloor must not exceed 3 lbs/1000 sq. ft
emissions or contain a Relative Humidity of 75% or less,
referring to ASTMF2170.Below are methods to test if moisture is present in the concrete
subfloor:1.- Use an approved calibrated concrete moisture meter as a
preliminary measurement for moisture such as: Delmhorst Moisture
Meter Model G Tramex Concrete Encounter. Follow manufacturer’s
specific calibration requirements.Generally, this type of
testing will only give you an idea if moisture may be present.
This does not imply a safe reading to install.2.- Perform a polyfilm test. Tape down 2’ x 2’ polyfilm squares
(a clear garbage bag or plastic drop cloth will do) in several
places on the floor. Wait 24 – 48 hours, and then check for the
appearance of condensation on the inside of the bag or plastic
for a darkening on the concrete subfloor. Either occurrence
signals the likely presence of excess moisture, requiring a
mandatory calcium chloride test or in-situ RH test ASTMC2170.Once you have determined the moisture content, a test must be
performed to determine the moisture and alkalinity emissions
through the concrete slab.– Perform a calcium chloride test according to the
manufacturer’s instructions. The maximum acceptable reading is
3-lbs. /24 hours/1000 sq. ft. for moisture emissions or RH
in-situ probe test have a max of 75%.– Perform a pH test according to the manufacturer’s
instructions. A pH reading of 6-9 on a pH number scale of 1 – 14
is acceptable.– If the test results exceed this number the concrete slab
should be sealed with appropriate sealers to correct those
emissions as per the manufacturer’s recommendations. -
Installation On Plywood And Wood Substrates: Do Not Install
Over Particleboard.Subfloor should be constructed of 5/8” or thicker plywood when
installing directly over minimum 2 x 10 floor joists 16” on
center. Plywood sheets should be laid with grained outer plies
at right angles to joists; adjacent rows staggered four feet and
nailed every 6” along each joist with 7D or larger nails. When
installing directly over old wood or strip floor, sand any high
spots, re-nail old floor to eliminate squeaks or loose boards,
and install new planks at right angle (perpendicular) to the old
floor, or over lay old floor with ¼” plywood underlayment. Leave
a 1/8” gap at the edges and nail with 7D or larger nails every
6” at the edges and every 12” in both directions and through the
interior of each sheet of plywood. The moisture content of the
wood or plywood should not exceed 13%. -
Job site Preparation
– Acclimate product for 72 hours prior to installation
– Verify subfloor is level to within 1/8” in 6’, and
structurally sound. Repair as needed– Undercut door casings
– Remove any existing wall base, shoe molding, quarter round and
doorway thresholds -
Getting Started
For optimal visual appeal, install parallel with the longest
wall. However, to reduce subfloor sagging, the floor should be
installed perpendicular to the flooring beams unless the
subfloor has been reinforced. Installation should start from the
straightest wall, usually an outside wall whenever possible. In
at least two places, at least 18” from the corner, measure out
equal distance from the starting wall and snap a chalk line.
This measurement must be the sum of the width of the flooring
plus an additional ¾” to allow for expansion space and the width
of the tongue. Allow ½” expansion when installing floating
floors. -
Installation – First Second Rows
For the first two rows, use boards that are among the longest
and straightest. Use the widest plank for the first row for
random and alternate width products. Align tongue of first row
on chalk line. The groove should be facing the starting wall.
Pre-drill ½” from back (groove) edge, 1” – 2” from each end, and
at 6” intervals when possible. Fasten using 4 or 6d finishing
nails or 1” pneumatic finish nails/ brads. Countersink the
nails.Pre-drill and blind-nail at a 45° angle through the tongue of
the first row every 1” – 2” from the ends and spaced in 8” to
10” intervals. To ensure flush engagement of groove with the
following row(s), countersink the nails. Continue blind nailing
using this method with following rows until stapler can be used.
Alternatively use a pneumatic finish nailer and install
nails/brads at the same intervals with a minimum length of 1
1/2”-2”. To ensure the desired overall appearance, stagger
end-joints of adjacent rows at a minimum of 4” to 6”when
possible.Please see nailing patterns chart at end of document.
-
Installing The Floor
Always use the recommended fastener for the specific product
being installed. Use a minimum 1 1/2” fastener recommended by
the stapler manufacturer 1”to 2” (2.5 – 5cm) from the ends
spaced at 8”to 10” intervals.Set compressor at 70 PSI. If tongue damage occurs, lower air
pressure. Fasten several sacrificial boards to the floor. Check
for surface damage, air pressure setting, tongue damage, edge
blistering, etc.., before proceeding. Make all adjustments and
corrections before installation begins. Once proper adjustments
have been made, remove and destroy the boards. Work from several
cartons when installing the floor to vary the depth and color of
the overall look. The last 1 to 2 rows will need to be face-on
the tongue side, following the nailing pattern used for the
first row. -
Glue-Down Installations (General Information)
The maximum adhesive working times for urethane adhesive is 60
minutes. When not in use, keep the adhesive container tightly
closed to prevent thickening. Thickening will cause difficulty
in spreading the adhesive. Open times and curing times of ALL
adhesives vary dependent upon subfloor porosity, air movement,
humidity and room temperature. Urethane adhesive has a shortened
working time in high humidity environments, whereas the working
time for polymeric resin adhesives will be lengthened. In areas
of low humidity, open time will be longer with urethane
adhesives and shorter with polymeric resin adhesives. Adjust the
amount of adhesive spread on the subfloor accordingly. The
adhesive should not be applied if subfloor or room temperature
is below 60° F (16° C). Working time will vary depending on job
site conditions.Hold trowel at a minimum 45° angle firmly against the subfloor
to obtain a 40 to 60 ft. per gallon spread rate. The trowel will
leave ridges of adhesive and very little adhesive between the
ridges. This will allow you to still see the chalk lines between
the ridges and provide the recommended spread rate. For
additional application instructions, follow the recommendations
on the adhesive container. Proper ventilation within the room
must be provided. An electric fan is helpful. -
Spread The Adhesive (Glue-Down Installations)
Spread sufficient amounts of the recommended adhesive with the
recommended trowel in an area that can be covered in 60 minutes.
If necessary, nail a sacrificial row with 1” nails on the dry
side of your chalk line to help hold the first row in place.NOTE: Avoid installing on the surface of the flooring. If
necessary, distribute weight using a kneeler board. -
Installing The Floor (Glue-Down Installations)
Use the longest, straightest boards available for the first two
rows. For random and alternate width products, use the widest
plank for the first row. The first row of planks should be
installed with the edge of the groove lined up on the chalk
line. The tongue should be facing the starting wall. The first
row must be aligned and seated in the adhesive, as all
additional rows will be pushed back to this original row. Remove
tongue to allow for expansion space, if necessary, on the row
adjoining the wall.When installing products wider than 3-1/4”, apply a bead of
recommended wood glue to all of the end grooves prior to
installing adhesive. When installing pieces, engage the
end-joint first, as close to the side (long) tongue and groove
as possible, then slide together tightly to engage the side
(long) joint tongue and groove. To avoid adhesive bleed-through
and memory pull-back, avoid sliding pieces through the adhesive
as much as possible when placing them in position.During the installation occasionally remove a piece of flooring
from the subfloor and inspect the back for proper adhesive
transfer. Adequate adhesive transfer is necessary to ensure
sufficient holding strength. If the adhesive skins over and
fails to transfer, remove and spread new adhesive to achieve
proper bonding. NOTE: Clean adhesive from the surface of the
floor frequently, using the recommended adhesive cleaner.
Urethane adhesives become extremely difficult to remove when
cured. Do not use tape before adhesive is removed from the
surface. Use clean towels, changed frequently, to prevent hazed
and adhesive residue.Check for a tight fit between all edges and ends of each plank.
End-joints of adjacent rows should be staggered 4” to 6” when
possible, to ensure a more favorable overall appearance. To
eliminate minor shifting or gapping of product during
installation, use house wrap tape to hold the planks together.
After installation is complete, remove all of the house wrap
tape from the surface of the newly installed flooring. Do not
let the tape remain on the flooring longer than 24 hours. Avoid
the use of masking or duct tape, which leaves an adhesive
residue and may damage the finish. If necessary, use weights to
flatten boards with bows until adhesive cures, in order to
prevent hollow spots. Boards that cannot be flattened should be
cut in length to reduce the bow, or not used. Be sure not to
spread adhesive too far ahead of your work area. Complete the
installation using the same technique for the remainder of the
floor. Avoid heavy foot traffic on the floor for at least 24
hours. Lift the furniture or fixtures back into place after 24
hours. -
General Information For Floating Floors
Floating floors can be installed over any structurally sound
surface that meets or exceeds local building codes. Any width of
flooring can be installed in this manner but wider widths are
preferred. Plan the floor layout (in width) to avoid having to
rip the last row narrower than 1”. This may require ripping the
first row to assure the last row is at least the minimum width.
Allow ½” expansion around all vertical obstructions. -
Installing The Underlayment
Acceptable Vapor Retarders Over Wood Subfloors:
A. ALWAYS FOLLOW LOCAL CODES AND MANUFACTURERS INSTRUCTIONS FOR
ACCEPTABLE VAPOR RETARDERS.B. An acceptable vapor retarder is a vapor resistant material,
membrane or covering with a vapor permeance (perm rating) of
greater than or equal to .7 and less than or equal to 50 when
tested in accordance with ASTM E-96 Method A. Installation of a
vapor retarder reduces the potential for moisture or vapor
related problems, but does not guarantee elimination of moisture
or vapor related problems. Install a vapor retarder over wood
panel or board sub-floors prior to installing nail down solid
strip or plank flooring. Over-lap seams a minimum of 4 inches or
more as required by manufacturer or specifier and local building
codes.C. Some examples of acceptable vapor retarders over wood
subfloors include:1.- An asphalt laminated paper meeting UU-B-790a, Grade B, Type
I, Style 1a.2.- Asphalt-saturated kraft paper or #15 or #30 felt paper
meeting ASTM Standard D-4869 or UU-B-790, Grade D.D. NOTE:
1.- A vapor retarder has some extra benefits in that it
eliminates wood-on-wood contact, wood strips slide more easily
when positioned, minimizes the impact of seasonal humidity
change and may reduce dust and noise levels.2.- However, by today’s standards, asphalt saturated kraft or
felt paper may not be an effective vapor retarder in all
applications. The 2006 International Residential Code requires a
vapor retarder on the warm-in-winter side of exterior floors (a
floor over a vented crawl space, for example), with a vapor
permeance of 1 perm or less in Zones 5 and higher.3.- Over a wood subfloor, do not use an impermeable vapor
retarder material with a perm rating of .7 or less, such as 6
mil polyethylene film or other polymer materials, as it may trap
moisture on or in the wood subfloor.4.- Do not use common red rosin or building paper which is not
asphalt saturated. They are not vapor retarders as their perm
rating is far greater than 50. -
Installing The Floor (Floating Installations Only – Not
Click)Select the first board. All installations should begin with the
groove side against the wall using the longest boards available.
Apply a continuous 1/8” glue bead to the inside bottom of the
groove on the end of the board. Do not apply glue to the groove
side at this time. Products with the end tongue on the left
should be installed right to left, opposite tongues should be
left to right. If a sacrificial board was used DO NOT glue the
first row to it. Complete the first row. Cut the last board
allowing for ½” clearance between the wall and the floor. (Use
the remaining end of the cut board as a starter board for any
row following row three).Install a wedge on the end of the board between the hardwood
flooring and the wall, allowing ½” expansion space. Avoid
installation of any boards shorter than 16” in the first four
rows. Use a pull bar to pull the last board into place from the
opposite end. Install wedges into the gap and tighten. If any
glue gets on the surface of the flooring, wipe off immediately
with a clean damp cloth. Cut or use a shorter board for the
first board of the second row. Start the second row by applying
1/8” bead along the inside bottom of the end and side groove of
the new board.Install the first board of row two. Apply a bead of glue to the
inside bottom of the end and side groove of the next board and
install. When installing boards together, use a tapping block
against the tongue, not the groove. Tap the boards into place by
tapping with a hammer on the tapping block. DO NOT tap on the
edge directly with the hammer. Complete the second through
fourth rows using this technique. Insert wedges on the ends, as
necessary, to restrain the movement of the floor.In the remaining rows, stagger joints 4” to 6” apart. Install
the rest of the floor. Be sure all joints are tight. Use spacers
on the long and butt walls. Use a tapping bar to tighten the
joints from the ends.Complete the Installation (All Installation methods)
