Wood Subfloors:
Preferred Wood Subflooring:
3/4” (23/32”, 18.3mm) CDX grade Plywood subfloor
/ underlayment (Exposure 1), 4’x8’ sheets or 1/8”
(23/32”, 18.3mm) OSB subfloor / underlayment
grade, PS2 rated, sealed side down, joist spacing of
19.2” (475) on center or less.
Minimum Wood Subflooring:
5/8” (19/32”, 15.1mm) CDX Plywood subfloor /
underlayment (Exposure 1), 4’x8’ sheets, maximum
16” on center joist construction. Follow panel
manufacturer’s recommendations for spacing and
fastening. Typical panel spacing and fastening for
joist systems, 1/8” (3.2mm) around perimeter and
fastened every 6” (150mm) on bearing edges and
every 12” (300mm) along intermediate supports.
Installation of flooring should not be made over joists
spacing greater than 19.2” on center or parallel to the
joists unless the subfloor has been properly
strengthened. Applying a second layer of
underlayment may be necessary to bring the overall
subfloor thickness to 1-1/8”.
Test the moisture content of the wood subfloor and
wood flooring with a pin type moisture meter. Wood
subfloors must not exceed 13% and the wood
flooring should be within 4% of the wood subfloor.
For existing wood floors install new flooring at right
angles to the existing flooring.
Do not glue, staple, or nail down hardwood flooring
over particle board, floating application is
acceptable (for products 3” or wider).
Do not install over existing glue down hardwood
floors.
Ceramic Tile and Terrazzo:
All wax and sealers must be removed with an appropriate
cleaner / stripper. Ceramic tile and terrazzo should he
abraded to allow for proper adhesion. Check for loose
tiles by tapping and re-adhering. Fill grout lines with a
cementitious latex fortified leveling compound.
Resilient Tile, Resilient Sheet Vinyl:
Material must be full spread and secured to the subfloor.
Do not install over perimeter glued floors. Do not install
over more than one layer that exceeds 1/8” in thickness.
Nail / Staple Down Only:
If old flooring is unsuitable to install new flooring
then overlay with new underlayment. Test to
conclude that the staples / cleats are able to properly
penetrate and secure the flooring to the subfloor.
Glue Down Only:
Do not install over more than one layer that exceeds
1/8” in thickness. Clean flooring with an appropriate
cleaner and allow to thoroughly dry. If necessary de-
gloss the floor using an abrasive pad to enhance the
bonding of the adhesive, if wax or other coatings are
present, completely remove the material with a
quality stripper, rinse the floor and allow to dry.
Always check for proper adhesion bond prior to
installing.
Acoustic Cork Underlayment:
Install cork underlayment according to manufacturer's
instructions.
The cork underlayment must be fully adhered to the
subfloor. The cork underlayment should be of pure
granulated cork combined with a polyurethane binder
with a minimum density of 11.4 lbs. per cubic foot and
not to exceed 13 lbs. per cubic foot.
Radiant Heated Subfloors:
Prior to installation of flooring over a radiant heat system
it is important that these guidelines are followed in strict
accordance. Failure to follow the guidelines may
produce unsatisfactory results.
JOBSITE REQUIREMENTS & INSTALLATION
Subfloor must be flat to 3/16” in 10’ or l/8” in 6’.
Concrete must be allowed to properly cure and dry for
a minimum of 4 weeks prior to operation of a radiant
heat system.
It is highly recommended that the radiant heat system
be designed specifically to accept a wood floor.
Follow the manufacturer’s installation instructions.
o Use of an in-floor temperature sensor as well a
separate thermostat for the individual room is
required.
o An outdoor temperature sensor should be used to
adjust water temperature according to anticipated
heat loss.
Radiant heat system should be set to run at 2/3
maximum output for a minimum of 2 weeks prior to
installation of flooring to further allow moisture from
concrete to dissipate and reach a final moisture
content. This must be done in both heating and non-
heating seasons.
Reduce to a temperature of 65° Fahrenheit for at least
4 days prior to flooring installation.
Prior to flooring installation moisture testing must be
conducted and documented per ASTM test method
1869-89 for concrete or using a pin type meter for
wood subfloors.
o The moisture content for concrete subfloors
registered after a calcium chloride test must not
be greater than 2 lbs. per 1000 square feet of
area. If it exceeds these limits, DO NOT install
the flooring.
o Wood subfloors may not exceed 13% and must
be within 4% of the wood flooring.
AFTER INSTALL & SEASONAL OPERATION
48 hours after completion of flooring installation
slowly raise the temperature of the heating system to
its preferred operating level over a period of 5 days.
Do not allow the surface temperature to exceed 82°
Fahrenheit.
Relative humidity of the jobsite must be maintained
between 35-55% relative humidity. Use of
humidification system may be required to maintain
the proper humidity level. Failure to maintain proper
humidity level can result in excessive dryness of
flooring.
Surface checking can be expected if the humidity
level is not properly maintained between 35-55%
R.H. or if the floor's surface temperature exceeds
82° Fahrenheit.
Seasonal gapping should be expected.
Refer to our Radiant Heat Precautions document
for other important information.
PRE-INSTALLATION: JOB PREPARATION
Inspect the Flooring:
Inspect material for color, finish, milling, and grade.
Hold out pieces that may not be acceptable once
installed. PLEASE NOTE: Manufacturer does not
accept responsibility for any costs incurred when
plank(s) with visible defects have been permanently
installed.
Undercut Door Casings:
Undercut all door casings l/16” higher than the
thickness of the flooring being installed. To do this, use
a scrap piece of flooring as a guide, lay it on the
substrate and cut the casing with a handsaw or use a
power jamb saw set at the correct height.
Blending of Cartons:
To achieve a uniform appearance across the entire
floor, you are urged to open / work from several cartons
at a time, and to dry-lay the flooring, mixing the planks
from several cartons. This will allow you to blend the
planks for maximum aesthetic appearance. Make
certain the room is well lit to ensure color is consistent
and that any visual defects can be seen and removed.
Match Transition Moldings:
For best appearance, be sure to match & blend all
transitions and moldings to planks that have similar
color and graining prior to installation, especially with
wide color range products. Set them aside for use as
needed.
Layout of Flooring:
Expansion space at vertical surfaces around the
perimeter of the room is required and should be
equal to the thickness of the flooring material. For
glue down installation, allow 1/4-3/8”. For staple /
nail down installation, allow 3/8-1/2”. For floating
installations the minimum is 1/2” regardless of the
thickness of the material. For commercial
installations use a minimum of 1/2” expansion.
Select a starter wall. An outside wall is best as it is
most likely to be straight and square with the room.
Measure out from this wall at each end: The overall
width of the plank (including the tongue), plus the
necessary expansion space. After determining the
direction to run the planks, measure the width of
the room (the dimension perpendicular to the
direction of the flooring). The last row of the
flooring should be no less than 1-1/2” wide; if it is
less, cut the width of the starter row to avoid a
narrow last row. If the first row requires ripping,
then measure from the wall the width of the ripped
board plus expansion space.
Snap a chalk line (using a brightly colored chalk)
from these points.
Insert spacers at walls to maintain the expansion
space between the flooring and the wall.
