Coastal Woodlands 3/8" &
1/2" Floating Floors for Floating or Glue-Down Installation
INSTALLER/OWNER RESPONSIBILITY
Beautiful hardwood floors are a product of
nature and therefore, not perfect. Our wood floors are manufactured in
accordance with accepted industry standards, which permit a defect tolerance
not to exceed 5%. The defects may be of a manufacturing or natural type.
-
The installer assumes all responsibility for final inspection of product
quality. This inspection of all flooring should be done before installation.
Carefully examine flooring for color, finish and quality before installing it.
If material is not acceptable, do not install it and contact the seller
immediately.
-
Prior to installation of any hardwood-flooring product, the installer must
determine that the job-site environment and the sub-surfaces involved meet or
exceed all applicable standards and recommendations of the construction and
materials industries. These instructions recommend that the construction and
subfloor be dry, stiff and flat. The manufacturer declines any responsibility
for job failure resulting from or associated with sub-surface or job-site
environment deficiencies.
-
Prior to installation, the installer/owner 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 defects, whatever the cause.
-
Use of stain, filler or putty stick for defect correction during installation
should be accepted as normal procedure.
-
When flooring is ordered, 5% must be added to the actual square footage needed
for cutting and grading allowance.
-
Should an individual piece be doubtful as to grade, manufacture or factory
finish, the installer should not use the piece.
-
Use of appropriate products for correcting subfloor voids should be accepted as
a normal industry practice.

PRE-INSTALLATION PROCEDURES
Job Site Inspection
-
The building should be closed in 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.
-
Exterior grading should be complete with surface drainage directing water away
from the building. All gutters and downspouts should be in place.
-
Floating floors may be installed on, above or below grade level. Do not install
in full bathrooms.
-
Basements and crawl spaces must be dry and well ventilated.
-
Crawl space must be a minimum of 24" (600 mm) from the ground to underside of
joists. A ground cover of 6-8 mil black polyethylene film is essential as a
vapor barrier with joints lapped six inches and taped. 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
(see figure #1).
-
Subfloor must be checked for moisture content using the appropriate testing
method.
|
|
-
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 and humidity of 35-55% for 14 days prior, during and until occupied,
to allow for proper acclimation
STORAGE AND HANDLING
andle and unload with care. 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 closed in 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. Floating floors should be stored in the
environment in which it is expected to perform. Air conditioning/heating
systems should be in place and in operation at least 14 days prior, during and
after installation of the flooring. Do not open the packages until you are
ready to install. Humidity may cause the tongue to swell on opened packages
making installation difficult. Check adhesive label for storage limitations.

SUBFLOOR REQUIREMENTS
-
CLEAN - Scrape, broom clean, and smooth. Free of wax, paint, oil, sealers,
adhesives, curing agents and other debris.
-
LEVEL/FLAT - Within 3/16" in 10' and/or 1/8" in 6'. Sand high areas or joints.
If the floor is to be glued down, fill low areas (no more than 1/8" at a time)
with a cementitous leveling compound or milk additive latex patch of 3,000-PSI
minimum compressive strength. Follow the instructions of the leveling compound
manufacturer. Leveling compounds must be tested for moisture to ensure they are
properly cured and within the manufacturer's specified requirements for proper
installation.
-
STRUCTURALLY SOUND - Nail or screw any loose areas that squeak. Replace any
water-damaged, swollen or delaminated subflooring or underlayments. Avoid
subfloor with excessive vertical movement unless they have been properly
stiffened prior to the installation of the wood flooring.
-
DRY - Check moisture content of the subfloor with a reliable moisture meter.
RECOMMENDED SUBFLOOR SURFACES
-
PREFERRED: ¾" (19 mm) CDX grade plywood
-
¾" (23/32") OSB PS2 rated underlayment
-
MINIMUM: 5/8" CDX grade plywood
-
Existing solid wood flooring
-
Vinyl, resilient tile, cork flooring
-
Concrete slabs
|
-
¾" chip, waferboard, particleboard
-
Radiant heated subfloors
-
Acoustic concrete
-
Ceramic, terrazzo, slate and marble
-
Metal
-
Cork (Acoustic)
|
CONCRETE SLABS
Floating floors can be glued directly to
concrete or floated over them. In glue-down applications, do not use a concrete
sealer nor install over one. Surface preparation using mechanical methods such
as sanding or scouring with open coat paper or a titanium disk is preferred.
The concrete must be of high compressive strength. All concrete subfloors
should be tested for moisture content. Visual checks are not reliable.
Acceptable test methods for subfloor moisture content include:
NOTE: Test several areas, especially near exterior walls and walls containing
plumbing.
-
A 3% Phenolphthalein in Anhydrous alcohol solution. Chip the concrete at least
¼" deep (do not apply directly to the concrete surface) and apply several drops
of the solution to the chipped area. If any color change occurs, further
testing is required.
-
Calcium Chloride test. The maximum moisture transfer must not exceed 3
lbs./1000 square feet with this test.
-
Tramex Concrete Moisture Encounter meter (figure #3). Moisture readings should
not exceed 4.5 on the upper scale. (Figure #3 shows an unacceptable reading of
over 4.5)
|
 |
A "DRY" SLAB, AS DEFINED BY THESE TESTS CAN BE
WET AT OTHER TIMES OF THE YEAR. THESE TESTS DO NOT GUARANTEE A DRY SLAB. ALL
CONCRETE SLABS SHOULD HAVE A MINIMUM OF 6 MIL POLY FILM MOISTURE BARRIER
BETWEEN THE GROUND AND THE CONCRETE.
Moisture Barrier System: If moisture is
present, inexpensive sheet vinyl or "slip-sheet" (PVC) may be installed. Use a
premium grade, alkaline resistant adhesive and a full spread application system
to properly bond the vinyl to the subfloor. Follow the sheet vinyl manufacturer
instructions for installation procedures. A patch test may be required as an
adhesion test. Install several small areas (3' x 3') and allow the vinyl to set
for 72 hours. Remove the vinyl; if the backing remains attached to the
concrete, the subfloor should be acceptable for sheet vinyl installation. If
you have any questions regarding installation or the handling of moisture
problems, please contact the distributor/retailer from whom the goods were
purchased.
ACOUSTIC CONCRETE
Acoustic concrete normally contains large
quantities of gypsum that may inhibit the adhesive's capability to properly
bond. For glue-down applications, acoustic concrete must be primed with the
concrete manufacturers recommended primer/surface hardener.
WOOD SUBFLOORS & WOOD STRUCTURAL PANEL
SUBFLOORS
Plywood: Must be APA grade rated sheathing or
CDX minimum.
Oriented Strand Board (OSB): Must be PS2 rated installed sealed side down.
Particleboard must be a minimum 40-LB density, stamped underlayment grade and
¾" thick.
Make sure existing floor or subfloor is dry and
well nailed or screwed down every 6" along each joist to avoid squeaking or
popping before the floor is installed. The wood subfloor must not exceed 13%
moisture content. Measure moisture content of both subfloor and wood flooring
to determine proper moisture content with a reliable wood moisture meter. The
difference between the moisture content of the wood subfloor and the wood
flooring must not exceed 4%.
Optimum performance of hardwood floor covering
products occurs when there is no horizontal or vertical movement of the
subfloor. The MINIMUM subfloor recommendations described above for 16" O/C
joist spacing. The thicker, PREFERRED subfloor recommendations described above
will allow 19.2" O/C joist spacing if the joist manufacturer's recommended span
is not exceeded. Spacing in excess of 19.2" O/C does not offer optimum results.
Install flooring perpendicular to the floor joists when possible. Installations
should not be made parallel to the floor joists or on joist spacing that
exceeds 19.2" O/C unless the subfloor has been properly stiffened. Stiffening
may require the addition of a second layer of subflooring material to bring the
overall thickness to at least 1-1/8".
All underlayment panels should be spaced 1/8"
apart to insure adequate expansion space. This can be achieved by using a
circular saw set at the depth of the underlayment and cutting around the
perimeter of the panel. T&G panels normally have built in expansion; DO NOT
cut around the perimeter of T&G panels. Do not install over existing
glue-down wood floors. Do not install over nailed floors that exceed 3-¼" in
width. Wide width floors must be overlaid with plywood. When installing over
existing wood floors parallel with the flooring, it may be necessary to install
an additional ¼" layer of plywood to stabilize the flooring or install the wood
floor at right angles. Applicable standards and recommendations of the
construction and materials industries must be met or exceeded.
RESILIENT TILE, RESILIENT SHEET VINYL &
CORK FLOORING
If the tiles or sheet goods are well bonded,
the flooring can be glued directly to the surface. Clean the surface thoroughly
with a good quality household detergent. De-gloss flooring as necessary to
create a good adhesive bond using an abrasive pad. If vinyl appears to have a
coating of wax or other maintenance materials, it must be removed with the
appropriate floor stripper. Allow ample drying time. (Note: Do not sand any
resilient products for they may contain asbestos fibers, which may be harmful.)
Do not direct glue to floors that exceed two layers; install as a floating
system only under these circumstances. Cork floors must have all sealers and
surface treatments removed before installation begins if a direct glue-down
application is preferred.
CERAMIC, TERRAZZO, SLATE & MARBLE
All grout joints and broken corners that exceed
1" must be filled with a cementitous leveling compound mixed with Latex
additive of a glue-down application is preferred. The surface should be cleaned
and abraded to create a good bonding surface for the adhesive. Loose tiles must
be re-adhered to the subfloor or filled as above for both glue-down and floated
applications.
CORK (ACOUSTIC)
Floating floors can be glued or floated
directly over full-spread, permanently bonded acoustic cork. The cork should
have a density of no less than 11.4 lb./cubic foot and no more than 13
lb./cubic foot. The cork, in general, should be pure cork combined with a
polyurethane binder. Cork thickness is to be no more than ¼" (6 mm). Install
cork in accordance with manufacturer's recommendations. DO NOT use cushion
underlayment when floating over these surfaces.
SUBFLOORS WITH RADIANT HEAT
-
System must be operational and heated for at least 7 days prior to beginning
installation.
-
Turn off heat and let subfloor cool down to room temperature 3-4 hours prior to
starting the job.
-
Radiant heated floors must be temperature controlled or engineered for the
R-rating of the floor-covering product installed upon them. BEFORE installation
begins, ascertain that the system is designed and controlled for wood flooring.
Failure to do so may cause excessive heat damage, shrinkage and delamination.
-
After installation, turn system back on immediately to its normal room
temperature setting. The subfloor surface must not exceed 85° F throughout the
life of the floor.
|
DOORWAY AND WALL PREPARATION
Undercut door casings. Remove any existing base, shoe mold or
doorway thresholds. These items can be replaced after installation. All door
casings should be notched out (figure #4) or undercut to avoid difficult scribe
cuts.
|
 |
|
GENERAL INSTALLATION TIPS
-
Floor should be installed from several cartons at the same time to ensure good
color and shade mixture.
-
Be attentive to staggering the ends of boards in adjacent rows at least 16"
when possible (figure #5). This will help ensure a more favorable overall
appearance of the floor.
-
DO install from closed/sealed cartons. DO NOT remove materials from their
sealed container prior to installation.
-
DO tighten panels by tapping against the recommended tapping block with a
hammer. DO NOT tighten panels by striking directly with the tapping block or a
hammer.
|
 |
-
DO glue all joints with EverSeal when using a floating system. The glue MUST be
applied to the top of the tongue, DO NOT apply adhesive in the groove
-
DO use a starter board that is adequately fastened to a straight starting line.
-
DO use Comfort Guard underlayment on all floating floors over subfloors that
require it.
-
DO Not use short tapping blocks that can damage the edge. Do Not use
lightweight wooden tapping blocks. Do Not use grooved tapping blocks.
-
DO NOT use laminate straps to tighten the flooring panels.
STEP 1: ESTABLISH A STARTING POINT
-
Installation parallel to the longest wall is recommended for best visual
effects, however, the floor should be installed perpendicular to the flooring
joists unless subfloor has been reinforced to reduce subfloor sagging. Find
appropriate subfloor from "Subfloor Type" section in this instruction manual.
-
When possible, always begin layout or installation from an outside wall, as
these are normally the straightest.
|
 |
-
Pre-plan the floor by counting the number of planks (in width) that it will
take to complete the floor. Avoid finishing out with a rip narrower than 2".
Plan to start the first row with a partial board, ripping it to the necessary
width to avoid a narrow rip on the final wall.
-
In at least two places 12"-16" from the corner, measure out equal distance from
the starting wall (figure #6) and snap a chalk line. The chalk should be of a
bright color so that it is visible through the underlayment or adhesive. If a
partial, ripped board is required (as above) it can be installed after the
balance of the flooring has been completed. Adjust the starting line to allow
for the width of the board plus ½" for expansion. Ascertain that the wall is
straight. If it is not, scribe the first row (figure #9) to allow for
irregularities.
-
Install a starter board on the inside edge of the chalk line aligned to create
a straight edge to work against (figure8A). Attach the starter board to the
subfloor using nails appropriate to the subflooring materials. When installing
using the floating system install the cushion underlayment BEFORE installing
the starter strip.
FLOATING FLOOR INSTALLATION
STEP 2: INSTALLING THE UNDERLAYMENT
-
Roll the underlayment in the same direction that the wood flooring is to be
installed.
-
Extend the underlayment a few inches up the wall. Excess will be trimmed off
prior to installing trim or moldings.
-
Firmly bond the sheets together to cover the entire floor. The floating floor
underlayment already has double sided tape for ease of taping the precut
overlapping seams (figure #7).
-
Always allow ½" expansion around all vertical objects.
|
 |
STEP 3: INSTALLING THE FLOOR
-
Select your first board; apply a continuous 1/8" glue bead to the top of the
tongue on "the end of the board." Do not apply glue to the side-tongue at this
time (Item C, figure #8).
-
Lay the first board (Item D, figure #8) with the grooves facing the edge of the
starter board and the left wall of the room. (Always leave expansion space).
-
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 after row three). Use an installation bar to pull the last
board into place. Install wedges into the gap and tighten (Item B, figure #8).
-
If any glue gets on the surface of the flooring, wipe off immediately with a
damp cloth.
-
Start the second row by applying a bead of EverSeal adhesive along the top side
of the tongue of row one.
-
Cut a board in half for the first board of the second row. Avoid installation
of any boards shorter than 25" in the first four rows which may reduce the
strength of the floor (Item F, figure #8).
-
In the remaining rows, stagger joints at least 16" apart. When installing
boards together, use a tapping block against the tongue, not the groove (Item
G, figure #8). Apply a bead of EverSeal to the tongue on the end and side (Item
C, figure #8). Tap the boards into place by tapping with a hammer on the
tapping block. DO NOT tap directly on the boards with the hammer. Install the
rest of the floor. Be sure all joints are tight. Use spacers on the long and
butt walls. Use an installation bar to tighten the joints from the ends. Remove
excess adhesive with a damp towel.
|
-
The final row of boards, in most installations, will need to be ripped
lengthwise to fit. The cut has to compensate for uneven walls and the expansion
clearance or gap necessary between the wall and the flooring. First lay up the
last row, face-up over the top of the last row permanently installed. Now using
a stub of a board and a pencil, scribe the proper guide lines and cut (figure
#9).
-
Use an installation bar to pull in the last row (figure #10) and install
wedges.
-
Remove the starter board and install the final row using the installation bar
as above.
-
Allow the completed floor to rest undisturbed (no foot traffic) for a minimum
of 8 hours before removing the wedges.
-
Before leaving the job site, check the floor under proper lighting for any
trace of glue on the surface. Use Bruce Adhesive Cleaner to remove stubborn
glue. Install molding the following day. Refer to the floor care and
maintenance section for maintaining your wood flooring.

GLUE-DOWN INSTALLATION
-
Maximum Adhesive Working Times
-
Equalizer Urethane Adhesive - 60 minutes (Always read container label before
proceeding)
-
Connection PR+ Polymeric Resin Adhesive - 90 minutes (Always read container
label before proceeding)
-
Open times and curing times of ALL adhesives vary dependant upon subfloor
porosity, air movement, humidity and room temperature. Urethane adhesives have
a shortened work time in high humidity environments whereas polymeric resin
adhesive working time will be lengthened. In areas of low humidity, open time
will be longer with urethanes and shorter with polymeric resins. Adjust the
amount of adhesive spread accordingly. The adhesive should not be applied if
subfloor or room temperature is below 65° F (20° C).
-
Spread sufficient amounts of Equalizer or Connection PR+ adhesive (shown in
header on page 1) with the recommended trowel (figure #2) in an area that can
be covered in 60-90 minutes. Polymeric resin adhesives should be rolled every
two hours and at the end of the day. If a urethane adhesive is to be rolled, do
not do so until the adhesive has cured for two hours.
-
NOTE: Avoid installing from the surface of the flooring. If necessary
distribute weight using a kneeler board. Always refer to specific adhesive
instructions on the adhesive label. Comfort Guard underlayment will not be used
in this application.
STEP 2: SPREAD THE ADHESIVE
-
Hold trowel at a minimum 45° angle (figure #11) firmly against the subfloor to
obtain a 50-60 sq. 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. If the adhesive skins over and fails to transfer, remove and spread new
adhesive to achieve proper bonding to the subfloor. WORKING TIME WILL VARY
DEPENDING ON JOB SITE CONDITIONS
|
|
-
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.
-
For additional application instructions, follow the recommendations on the
adhesive container.
-
When not in use, keep the adhesive container tightly closed to prevent
thickening. Thickening will cause difficulty in spreading the adhesive.
-
Proper ventilation within the room must be provided. An electric fan is
helpful.
-
If the floor is to be covered, use a breathable material such as cardboard. Do
not cover with plastic.
NOTE: Clean adhesive from the surface of the
floor frequently using the recommended adhesive cleaner. Do not use blue tape
before adhesive is removed. Use a clean towel, changed frequently to prevent
haze and adhesive residue.
STEP 3: INSTALLATION OF FLOORING
-
Use the straightest boards available for the first two rows. The first row of
planks should be installed with the edge of the groove lined up against the
starter board. The tongue should be facing the ending wall. The first row must
be aligned and seated in the adhesive as all additional rows will be pushed
back to this original row.
-
Apply a bead of EverSeal to all of the end tongues prior to installing into the
adhesive. Gluing of the edges is not necessary in glue-down applications.
-
Use wedges against the starting wall to prevent movement. Tighten or loosen as
necessary to allow for variations in the wall, always keeping planks aligned
with the chalk line.
-
Avoid working from the surface of the newly installed floor to prevent
scooting. Use a kneeler board if necessary to distribute weight.
-
When installing planks, engage the end-joint first as close to the side (long)
tongue and groove as possible and then slide together tightly to engage 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.
-
Check for a tight fit between all edges and ends of each plank. End-joints of
adjacent rows should be staggered 16" when possible to ensure a more favorable
overall appearance.
-
Use a glue-down tapping block and a hammer to tighten all joints.
-
To eliminate minor shifting or gapping of product during installation, use 3M
2090 Blue Mask Tape to hold the planks together. After installation is
complete, remove all the 3M 2090 Blue Mask Tape from surface of newly installed
flooring. Do not let tape remain on flooring longer than 24 hours. Avoid use of
masking tape which leaves an adhesive residue.
-
Be sure not to spread adhesive too far ahead of your work area.
-
Complete the installation using this same technique for the remainder of the
floor.
-
Remove the starter board and install the final row as above.
-
Avoid heavy foot traffic on the flooring for at least 24 hours. Lift the
furniture or fixtures back into place after 24 hours.
INSTALLERS - ADVISE YOUR CUSTOMER OF THE
FOLLOWING
SEASONS: HEATING AND NON-HEATING
Recognizing that wood floor dimensions will be
slightly affected by varying levels of humidity within your building, care
should be taken to control humidity levels within the 35-55% range. To protect
your investment and to assure that your floors provide lasting satisfaction, we
have provided our recommendations below.
-
Heating Season (Dry) - A humidifier is recommended to prevent excessive
shrinkage in wood floors due to low humidity levels. Wood stoves and electric
heat tend to create very dry conditions.
-
Non-Heating Season (Humid, Wet) - Proper humidity levels can be maintained by
use of an air conditioner, dehumidifier, or by turning on your heating system
periodically during the summer months. Avoid excessive exposure to water from
tracking during periods of inclement weather. Do not obstruct in any way the
expansion joint around the perimeter of your floor.
FLOOR REPAIR
Minor damage can be repaired with the Bruce
Touch-Up Kit or Acrylic Filler. Major damage will require board replacement,
which can be done by a professional floor installer.
ALL INSTALLATIONS
STEP 4: COMPLETING THE JOB
-
Clean floor with the Bruce Dura-Luster Cleaner. (See adhesive container for
specific information)
-
Re-install any transition pieces that may be needed, such as Reducer Strips,
T-moldings, or Thresholds. The products are available pre-finished to blend
with your flooring. (See moldings below)
-
Re-install all base and/or quarter round moldings. Nail moldings into the wall,
not the floor. Inspect the floor, filling all minor gaps with the appropriate
blended filler.
-
If the floor is to be covered, use a breathable material such as cardboard. Do
not cover with plastic.
-
Leave warranty and floor care information with the owner. Advise them of the
product name and code number of the flooring they purchased.
-
To prevent surface damage avoid rolling heavy appliances and furniture on the
floor. Use plywood, hardboard or appliance lifts if necessary.
MOLDINGS
-
Reducer Strip: a teardrop shaped molding. Used around fireplaces, doorways, as
a room divider, or as a transition between Parquet and adjacent floor coverings
that are thinner. Fasten down with adhesive or double-faced tape.
-
Threshold: a molding undercut for use against sliding door tracks, fireplaces,
carpet, ceramic tile, or existing thresholds to allow for expansion space and
to provide a smooth transition in height difference. Fasten to subfloor with
adhesive and/or nails through the heel. Predrill nail holes to prevent
splitting. Always leave expansion beneath the undercut.
-
Stair Nosing: a molding undercut for use as a stair landings trim, elevated
floor perimeters, and stair steps. Fasten down firmly with adhesive and nails
or screws. Predrill nail holes to prevent splitting.
-
Quarter Round: a molding used to cover expansion space next to baseboards, case
goods, and stair steps. Predrill and nail to the vertical surface, not into the
floor.
-
Combination Base and Shoe: a molding used when a base is desired. Used to cover
expansion space between the floor and the wall. Predrill and nail into the
wall, not the floor.
-
T-Molding: a molding used as a transition piece from one
flooring to another or to gain expansion spaces. Fasten at the heel in the
center of the molding. Leave expansion beneath the undercut on both sides.
