GENERAL INFORMATION
The key to a successful and trouble-free installation is thorough
preparation. Do not install LVT flooring without first performing a
thorough on-site evaluation (including jobsite testing), ensuring that
subfloor preparations are finished, and that the work of all other trades
has been completed. Site conditions must comply with the information
provided within this document, with the requirements detailed in ASTM
F710, “How to Prepare Concrete Substrates to Receive Resilient
Flooring,” as well as relevant building codes, and local, state and national
regulations. Note: It is highly recommended to have substrate moisture
and pH testing conducted by a certified ICRI (International Concrete
Repair Institute) Tier 2 technician. Documentation of moisture and pH
test results may be required when submitting LVT claims.
•L
VT is available in different sizes and formats. Note: Be aware
that some LVT products are square edge and some are microbeveled. Mixing different edge treatments together will require
hand beveling of the square edge material.
• LVT is intended for interior use only and is suitable for above-grade,
on-grade and below-grade applications. However, LVT should not
be installed in locations where the substrate beneath the building
structure is exposed to the elements.
• LVT is not recommended for exterior installations or for use in areas
that are not climate-controlled.
• LVT is recommended for the use over properly prepared concrete,
suspended wood, metal and other suitable substrates.
• Acclimate flooring, adhesives, and the job-site: only install LVT in
climate-controlled structures consistently maintained at temperatures
between 65°-85°F (18°-29°C) and 35%-85% RH a minimum of 48
hours before, all times during, and continuously after installation.
• Protect LVT from foot traffic for 24 hours after installation. Do not wash
LVT for five days after installation.
JOBSITE INSPECTION AND TESTING
Prior to installation, plan and attend an on-site construction meeting
with the General Contractor, Architect, and Property Owner to review all
requirements and inspect site conditions as outlined in this document, as
well as those outlined in ASTM F710, and any relevant building codes,
and local, state or national regulations. Flooring installation should not
begin until all site conditions have been assessed, testing has been
completed, the subfloor has been prepared, and all conditions are in
compliance. Defects should be addressed immediately and corrected
before installing LVT Flooring. Installation of material constitutes
acceptance of all conditions.
1. The building must be completely sealed before jobsite testing can
begin (ASTM F710). This includes: windows, doors, roofing, walls,
etc.
2. I nterior environmental conditions must be maintained at
65°-85°F (18°-29°C) and 35%-85% RH a minimum of 48 hours
before testing, and at all times during testing (ASTM F710).
3. Plan, prepare, and protect the substrate moisture test-sites for the
duration of the testing in order to achieve valid results.
4. S ubfloor flatness for all substrates shall not exceed 3/16"
in 10 ft. (3.9mm in 3m).
MATERIAL RECEIVING, HANDLING AND STORAGE
1.Upon receipt, immediately remove any shrink-wrap and check
material for damage, and that the material is of the correct style,
color, quantity, and run number(s).
2.Immediately report any discrepancies.
3.General Storage: Store all materials flat and off of the floor in an
acclimatized, weather-tight space between 65°-85°F (18°-29° C). Do
not double-stack pallets.
4.Jobsite: Acclimate LVT material and adhesives in the acclimatized
jobsite between 65°-85°F (18°-29°C) and 35%-85% RH for 48 hours
prior, all times during, and maintain temperature continuously after
installation. Spread unopened cartons no more than 6 cartons high
and at least 4" apart. Keep away from heating and cooling ducts and
direct sunlight. If permanent HVAC is not yet operational, temporary
means should be used to maintain the noted temperature and RH.
SUBFLOOR PREPARATION
LVT can be installed on wood, concrete, terrazzo, stone, and many
other properly prepared subfloors, including in-floor heating. One key
factor to ensuring an excellent, finished appearance of an LVT floor is
careful subfloor preparation. The information provided in this document
includes general recommendations on how to prepare various types of
subfloors. The selection of all materials, including: moisture-mitigation
systems, self-leveling compounds, floor patch products, wood
underlayments, and any other ancillary products are dependent upon
existing conditions. The application of subfloor preparation materials
must be in strict accordance with the manufacturer's instructions.
All warranties and guarantees pertaining to the suitability and
performance of any preparation or ancillary product rests solely
with that material manufacturer or the Flooring Contractor. The
condition of the subfloor and bond issues resulting from the use of
non-recommended, improper, or incorrectly prepared adhesives,
sealers, embossing levelers, patches, concrete, gypsum-based
products and other such items, are the sole responsibility of the
Flooring Contractor, General Contractor, and/or manufacturer of
the particular sub-flooring product.

Product Description
Dryback LVT/LVP
CONCRETE SUBFLOORS
GENERAL CONDITIONS
All concrete floors, regardless of age or grade level must be properly
cured, free of excess moisture, and prepared in accordance to the
most current version of ASTM F710 (Standard Practice for Preparing
Concrete Floors to Receive Resilient Flooring). Below and on-grade
concrete subfloors must have a suitable vapor retarder properly
installed beneath the slab (ASTM E1745). The surface of concrete
floors to receive resilient flooring shall be dry, clean, smooth, and
structurally sound. They shall be free of dust, solvent, paint, wax, oil,
grease, residual adhesive, adhesive removers, film-forming curing
compounds, silicate penetrating curing compounds, sealing, hardening,
or parting compounds, alkaline salts, excessive carbonation or laitance,
mold, mildew, and other foreign materials that might affect the rate of
moisture dissipation from the concrete, the adhesion of resilient flooring
to the concrete, or cause a discoloration of the flooring from below (ACI
302.1 and ASTM F710). Non-chemical methods for removal, such
as scraping, abrasive cleaning, or bead-blasting, including methods
described in ASTM D4259 (Standard Practice For Abrading Concrete),
may be used on existing slabs with deleterious residues. In all cases,
the subfloor must meet the moisture and pH requirements prior to
installation.
Warning: Concrete Subfloors Containing Coal Fly Ash: Fly ash is
routinely used in cement in LEED-certified projects. No doubt it will
continue to grow in popularity as LEED points become the norm in
commercial construction. Fly ash contains silicon dioxide and calcium
oxide. Silicon is difficult to bond to, and calcium oxide is a caustic,
alkaline by-product which plays havoc on flooring adhesives. Installing
floors on concrete substrates containing coal fly ash can be problematic
and therefore may require aggressive scarification or shot blasting
prior to installation of flooring materials. Perform bond test prior to the
installation of LVT flooring. Refer to the manufacturer’s instructions of
such subfloor preparation products for guidance regarding the proper
use of their products.
Moisture and Alkalinity: Perform either the In-Situ Relative Humidity
(RH) test (ASTM F2170) or Moisture Vapor Emission Rate (MVER) test
(ASTM F1869) in strict accordance to the most current version. Test
surface alkalinity per ASTM F710. Refer to the adhesive manufacturer
for acceptable moisture and pH ranges. Follow the adhesive instructions
located on the product label, or contact the manufacturer for further
information. If test results exceed recommended adhesive tolerances for
moisture, then the area must be allowed to further dry to an acceptable
level, or remediated using a moisture-mitigation system before installing
LVT. (Note: see “Moisture Mitigation” section, page 6). Concrete
floors should be tested for pH following the procedures outline in the
most current version of ASTM F710. Rinsing and vacuuming with clean,
potable water is the best way to lower surface pH, but it will not prevent
future issues. Do not acid-rinse concrete floors to neutralize pH. Some
moisture-mitigation systems are designed to control pH. Electronic
meter testing is not considered a replacement for a Calcium Chloride
Test or Relative Humidity Test.
ATTENTION: Mold and mildew grow only in the presence of
moisture. Jobsite mold and moisture issues must be addressed
and corrected prior to installation. Please visit www.epa.gov/mold
for information about safely preventing and removing mold, mildew
and other biological pollutants.
Floor Flatness: The surface shall be flat to 3/16" in 10 ft. (3.9 mm in 3
m). Level high spots by sanding, grinding, etc. and fill low spots. Smooth
surface to prevent any irregularities or roughness from telegraphing
through the new flooring.
Concrete PSI: Concrete substrates must have compression strength
of 3,000 psi or greater.
Installation Method
Glue Down
Concrete Absorbency: Be aware that absorbent (porous) and nonabsorbent (non-porous) subfloors may require different trowel sizes
for adhesive application. Check absorbency by randomly placing 1"
diameter droplets of water directly onto the surface of the concrete
subfloor. If the water droplet does not dissipate within 60-90 seconds,
then the substrate is considered non- absorbent. Even after removing
old, glued-down flooring materials, do not assume that the concrete is
absorbent (porous). Often, the old adhesive has sealed the floor. Follow
adhesive manufacturers instructions for recommended trowel sizes.
Chemical Abatement / Other Contaminants: The use of adhesive
removers or solvents in the abatement process or removal of
existing or old adhesives is prohibited, and may void the warranty.
If oil, grease or other contaminants have deeply penetrated the
concrete and cannot be thoroughly removed, do not install LVT
Luxury Resilient Flooring.
Expansion Joints / Isolation Joints: Such joints (or other moving
joints) are incorporated into concrete floor slabs in order to permit
movement without causing random cracks in the concrete. These joints
must be honored and not be filled with underlayment products or other
materials, and floor coverings must not be laid over them. Expansion
joint covering systems should be detailed by the architect or engineer,
and based upon intended usage and aesthetic considerations.
Treating Surface Cracks: Cracks, grooves, depressions, control
joints, or other non-moving joints, and other irregularities shall be filled
or smoothed with high-quality Portland cement-based patching or
underlayment compounds for filling or smoothing, or both. Some surface
cracks may need to be chased and filled. Patching or underlayment
compound shall be moisture, mildew,and alkali-resistant, and shall
provide a minimum of 3,000 psi compressive strength after 28 days,
when tested in accordance with Test Method ASTM C109 or ASTM
Test Method C472, whichever is appropriate. Refer to manufacturer’s
instructions of such subfloor preparation materials for more details.
Self-Leveling and Patching: For concrete subfloors, use only
high-quality Portland cement or synthetic, gypsum-based materials
(minimum 3,000 psi compressive strength per ASTM C109), and
allow to dry according to manufacturer’s instructions. Self-leveling
compounds may have very high moisture content, thus requiring longer
curing times. Note: Adding latex to levelers will normally make the floor
NON-POROUS. Test for porosity and follow non-porous adhesive
recommendations, if necessary. FOLLOW THE MANUFACTURER’S
INSTRUCTIONS, AND DO NOT OVER-WATER PATCHING AND
LEVELING COMPOUNDS. The installer is responsible for observing
cure times, moisture content, adhesive bonding, and the structural
integrity of any leveling or patch compound used.
WARNING: Do not lightly skim-coat highly polished or slick,
power-troweled concrete surfaces. A thin film or residue of
floor patch will not bond sufficiently to a slick subfloor and may
become a bond breaker, causing tiles to release at the interface
of the subfloor and patching material. In addition, it may be an
unnecessary, added expense
NEW CONCRETE
New concrete subfloors contain a high percentage of residual moisture.
Allow new concrete, including lightweight and gypsum toppings, to
cure for at least 90 days before conducting moisture tests. In lieu of
wet curing, quite often curing agents are applied to concrete slabs to
retard the escape of water during the initial curing process. Compounds
left on the slab can retard the escape of free-water during the drying
process and eventually break down over time after the flooring is
installed, affecting the integrity of the bond. Solvent-based adhesives
will not adhere, and water-based adhesives will not set-up and properly
cure. Note: In the event of adhesion failure, the responsibility for
warranties and performance guarantees rests with the compound
manufacturer.

Product Description
Dryback LVT/LVP
OLD CONCRETE
Old or existing concrete subfloors may pose more of a risk than new
concrete, therefore requiring special attention. Remove existing floor
covering, all traces of old adhesives, paint, or other contaminants by
scraping, sanding, grinding, shot-blasting or scarifying the substrate.
The use of adhesive removers or solvents in the abatement or
removal of existing or old adhesives is prohibited and may void
the LVT warranty.
WARNING: ASBESTOS & SILICA – Refer to the current Resilient
Floor Covering Institute (RFCI) document “Recommended Work
Practices for Removal of Existing Resilient Floor Coverings” for
guidance.
POWER-TROWELED CONCRETE
Power-troweled concrete surfaces can be very slick, relatively nonabsorbent, and may produce surface laitance. These conditions can
have an adverse effect on the bondability of subfloor preparation
materials, flooring adhesives, and therefore mechanical preparation
(such as shot-blasting or scarification) is recommended. Always
perform bond tests to determine suitability.
Lightweight Concrete: The minimum density of lightweight concrete
should be greater than 90lbs. per cubic foot, with minimum compression
strength of 2,500 psi or greater. Perform only In-Situ Relative Humidity
(RH) test in strict accordance to the latest edition of ASTM F2170.
Existing lightweight concrete or gypsum substrates may need to
be primed prior to the installation of flooring. Contact the Subfloor
Preparation manufacturer for recommendations, and always perform a
bond test before proceeding. You can also contact Customer Service.
In-Floor Heating: Radiant heating systems must be cast ½" below the
surface of the concrete slab, and should be operating at least 2 weeks
before installing LVT flooring. Set the temperature of the radiant heating
system to 68°F 48 hours before, at all times during, and 72 hours after
installation. The temperature of the radiant heat floor may be gradually
increased 72 hours after installation, but the surface temperature should
never exceed 85°F. Contact the manufacturer of your radiant heating
system for further recommendations.
MOISTURE MITIGATION
Concrete subfloors that exceed the maximum moisture value per
the specified adhesive must be brought into compliance prior to the
installation of LVT flooring (Refer to the adhesive manufacturer for
moisture tolerances). Due to the complexities associated with concrete
moisture vapor emissions and movement of soluble salts in concrete
subfloors, a specific product is not warranted. The use of products that
meet the criteria listed in ASTM F3010 (Standard Practice for TwoComponent Resin Based Membrane-Forming Moisture Mitigation
Systems for Use Under Resilient Floor Coverings) are recommended.
Refer to recommended Subfloor Preparation Materials under the
“Subfloor Preparation” section in this document.
WOOD SUBFLOORS
GENERAL CONDITIONS
LVT is recommended for use on suspended wood subfloors. Wood
subfloors should have standard, double-layer construction with a
minimum total thickness of at least 1" (25mm). As a finish layer, use
minimum ¼" (6mm) thick, APA-rated “underlayment grade” plywood
with a fully sanded face, or other underlayment panel that is appropriate
and warranted for the intended use. Follow manufacturer’s instructions.
Wood subfloors must be sturdy, sound, and flat within 3/16" in a 10-foot
radius, and should not slope more than 1" per 6 ft. in any direction, with
a minimum 18" (45cm) of well- ventilated air space underneath. Crawl
spaces should be insulated and protected by a vapor barrier. Do not
install LVT flooring over a sleeper type subfloor, or over plywood that
Installation Method
Glue Down
is in direct contact with a concrete slab. All wood substrates must meet
national and local building code requirements. Test wood subfloors
and underlayment panels using a suitable wood-moisture meter. The
maximum moisture content is 14%, and the readings between the
subfloor and underlayment panels should be within 3% prior to installing
the underlayment panels.
UNDERLAYMENT PANELS:
Underlayments for resilient flooring must be:.
•Structurally sound
• Specifically designed and warranted for resilient flooring
• A minimum of ¼" (6mm) thick
• Of a smooth surface, so as to prevent telegraphing
• Able to resist indentations
• Free of any substances that may cause flooring to stain
Plywood: Use only American Plywood Association (APA) rated
underlayment grade plywood, with a minimum grade of “BB” or “CC”,
and minimum ¼" thickness. Allow expansion spacing between plywood
butt joints of 1/32"–1/16", or follow manufacturer’s instructions. When
installing underlayment, stagger cross-joints 4' on an 8' panel (minimum
16"), lightly butt the panels, and set fasteners flush or slightly below
the surface level of the underlayment. Fill underlayment seams, nail
holes, and any indentations with an approved Portland Cement-type
floor patch, allow recommended drying time, and sand the patch until
smooth. Otherwise, use manufacturer-certified poplar, birch, and spruce
plywood underlayment, with a fully sanded face and exterior glue. All
dust must be COMPLETELY removed to ensure a strong adhesive
bond. Vacuum or sweep thoroughly, then apply adhesive.
Lauan Plywood: Use only Type 1 lauan exterior grade “BB” or
“CC” for underlayment. The use of lesser grades of lauan plywood
is unacceptable, and may cause severe problems when used as an
underlayment, including: discoloration, indentation, loss of bond, and
delamination.
NOTE: The use of lauan plywood and other extremely porous
wood underlayments will reduce the flash and working time of
adhesives. It is best to apply an acrylic-based primer-sealer to
any porous substrate prior to installing LVT. A manufacturer’s
certification of lauan grade must accompany any claim involving
the use of a lauan underlayment.
UNAPPROVED SUBSTRATES
Remove the floors listed below and refer to the appropriate “General
Conditions” subsection under the “Concrete Subfloors” and “Wood
Subfloors" sections. For glued-down floors, remove old adhesive
before installing LVT. Encapsulate adhesive and cutback residue.
Any appearance- or performance-related issues associated with the
underlayment are the responsibility of the flooring contractor and/or
underlayment manufacturer.

Product Description
Dryback LVT/LVP
NOTE: Various Federal, State, and Local government agencies
have regulations governing the removal of in-place asbestoscontaining material. If you contemplate the removal of a resilient
floor covering structure that contains (or is presumed to contain)
asbestos, you must review and comply with all applicable
regulations. Do not sand, dry sweep, dry scrape, drill, saw, bead
blast, or mechanically chip or pulverize existing resilient flooring,
backing, lining felt, asphalt “cut-back” adhesive, or other adhesive.
These products may contain asbestos fibers and/or crystalline
silica. 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 bodily harm. Unless
positively certain that the product is a non-asbestos containing
material, you must presume it contains asbestos. Regulations may
require that the material be tested to determine asbestos content.
RFCI’s Recommended Work Practices for Removal of Resilient
Floor Covering are a defined set of instructions addressed to the
task of removing all resilient floor covering structures. For further
information, visit the Resilient Floor Covering Institute website at
www.rfci.com.
OTHER SUBFLOORS
GENERAL CONDITIONS
It is always best practice and recommended to remove existing flooring
and start new with the original base. Recognizing that there are certain
situations in which this is not possible, existing flooring materials such
as terrazzo, marble, ceramic tile, or quarry tiles may be a suitable
substrate for LVT if properly prepared. Note: Special attention in the
preparation of these substrates must be taken. Consult with substrate
preparation material supplier for appropriate material selections,
application requirements, and warranty information. The responsibility
of the assessment, determination, and selection of the substrate
preparation material, along with application and product performance,
rests with the applicator and preparation material provider.
Terrazzo and Stone Subfloors: These materials are porous and allow
moisture to pass through. As such, the subfloor must be tested for
moisture and pH, as outlined in the "Moisture and Alkalinity" subsection
under "Concrete Subfloors". If the moisture and pH do not meet the
tolerances of the appropriate adhesive, moisture mitigation is required.
Any loose or damaged tiles must be repaired or removed. Thoroughly
clean the surface to remove all old sealants, varnishes, oil, grease, wax,
or finishes. Roughen smooth or glazed surfaces to provide a mechanical
key for self-leveling compounds or preparation materials. Follow the
manufacturer’s recommendations for such preparation materials.
Existing Resilient Floors: LVT may be installed over a single layer
of existing resilient flooring, on-grade and suspended moisture-free
substrates (never below grade), when properly prepared. Never
install over existing cushion vinyl, rubber, or slip-retardant flooring.
The existing material must be fully and firmly bonded to an approved
subfloor or underlayment. All polishes, waxes, floor finishes, and
contaminants must be properly stripped. Indented or damaged areas
must be replaced or repaired. Use appropriate patching, repair or
embossing levelers.
Embossing Levelers: Use embossing levelers on sheet goods with
textures that could telegraph through flooring. Self-leveling compounds
must fully cure according to manufacturer’s instructions before installing
LVT flooring. The flooring contractor is fully responsible for moisture
and leveler-related issues. Note: The use of embossing levelers on
sheet goods will not create a porous subfloor.
Installation Method
Glue Down
contaminates that may interfere with the adhesive bond. The surface
may require cleaning with mineral spirits to remove oil or grease prior to
abrading or lightly sanding the surface to achieve a satisfactory bond.
A bond test should be performed prior to installation. Metal substrates
require the non- porous application method. Due to the softness of lead,
it is recommended that it be coated with a minimum of 1/8” cementbased underlayment. While this may not be a requirement for thin
applications of lead, it must be understood that lead will indent quite
easily. A bond test should be performed prior to installation. Contact
Customer Service for details.
Polymeric Poured Floors: These type of floors are generally two-part,
resin-based, epoxy paints or coatings. It’s very difficult to tell whether or
not they are well bonded to the substrate and are subject to issues with
excessive moisture. Thus, it is recommended that polymeric poured
floors be removed, so as to avoid potential problems.
SPECIAL CONSIDERATIONS
Radiant Heat: Radiant heating systems must be cast ½" below the
surface of the concrete slab, and should be operating at least 2 weeks
before installing LVT flooring. Set the temperature of the radiant heating
system to 68°F 48 hours before, at all times during, and 72 hours after
installation. The temperature of the radiant heat floor may be gradually
increased 72 hours after installation, but the surface temperature should
never exceed 85°F. Note: For best performance it is recommended
to use a Two-Part Epoxy Adhesive over floors with radiant heating.
Follow adhesive manufacturers instructions.
Removal of Existing Resilient Flooring - Asbestos Abatement:
It is recommended following the Resilient Floor Covering Institute
Guidelines for removal of existing tile and mastic. Existing resilient
flooring and adhesive should be mechanically removed. The use of
adhesive removers or solvents is strictly prohibited. Any mastic remover
residue including Soy or Citrus products can attack and break down
the new adhesive, resulting in tiles releasing from the subfloor. Floor
covering warranties do not cover instances where adhesive removers
or solvents cause damage to the flooring or installation failure.
Concrete Curing, Sealing, Hardening or Parting Compounds: Wet
curing concrete for seven days is recommended, if at all possible.
This will prevent the need to use curing, sealing, hardening, or parting
compounds. Curing compounds leave a film that can interfere with
the adhesion of floor coverings, and thus their use should be avoided.
Some contain wax, soap, oils, or silicones, and must be removed prior
to installing resilient flooring. Mechanically remove compounds by using
a concrete or terrazzo grinder, or by shot-blasting. Some materials are
advertised as being “dissipative,” but should not be taken for granted.
Always conduct bond tests to determine the need for removal (see
“Adhesive Bond Testing” section, directly below).
ADHESIVE BOND TESTING
Use the following test to determine if a subfloor is compatible for use
with the adhesives, or to determine if the porous or non-porous adhesive
application method is required: Using the flooring and adhesive suitable
for the subfloor, install a 3' x 3' section following the recommended
installation procedures. Tape the edges with duct tape to prevent the
adhesive from prematurely drying. Select light traffic areas, such as
those located next to walls or columns. The adhesive should be dry
and the flooring should be difficult to remove after 48 hours. Note: the
adhesive is dry at this point, but not cured. Full cure and maximum
bond will not occur for 6-8 days. On large installations, tests should be
performed every 50 linear feet.
Metal Substrates: It may be possible to install directly over steel,
stainless steel, aluminum, and lead substrates using the appropriate
adhesive but confirm and follow the adhesive manufacturers
recommendations. These types of substrates must be thoroughly
cleaned, dried and free of dust, dirt, wax, paint, grease, or any other

ADHESIVES
GENERAL INFORMATION:
Areas of usage and subfloor conditions determine the appropriate
adhesive. For areas with high point loads, rolling loads, topical spillages,
radiant heat or direct sunlight only use Two Part Epoxy. Always use new
trowels to ensure proper adhesive coverage.
INSTALLATION
GENERAL INFORMATION
Before starting the installation, verify that the material is of the correct
style, color, quantity, and run numbers, and ensure that the correct
adhesive has been selected for area of usage. Also, confirm that all preinstallation requirements, as detailed in the remainder of this section,
have been satisfactorily completed. Start of flooring installation indicates
acceptance of current subfloor conditions and full responsibility for
completed work.
CHECK RUN NUMBERS AND MANUFACTURE DATE
Locate the run number on the short end of each carton and verify that all
of the material for your job is from the same run. Minor shade variations
within the same run number contribute to the natural look of LVT. To
avoid noticeable shade variations, do not install material from different
runs across large expanses.
To determine manufacture date, locate the run number on the short end
of the carton. It is the eight-digit number separated by decimal points
beginning with the two-digit day, then the two-digit month, and finally
the four-digit year. EX: 15.07.2018 (Day.Month.Year)
•
Acclimate tiles (keep cartons flat), adhesive, jobsite, and subfloor to a
stable condition between 65°-85°F (18°-29°C) and 35%- 85% RH for
a minimum of 48 hours before and after installation.
•Confirm quantity of LVT flooring and adhesive are sufficient for area
to be installed. Check material for visual defects before installation.
Installation of flooring acknowledges acceptance of materials.
•Make sure all surfaces to be covered are completely clean, dry,
and smooth, and that all necessary subfloor preparation has been
properly completed and documented.
•Perform final acceptance inspection of substrate.
•Protect adjacent work areas and finished surfaces from damage that
could occur during product installation.
•LVT should be the last material installed, so as to prevent other
trades from disrupting the installation and adhesive set-up, and to
prevent damage to the floor.
LVT can come in plank, rectangular, and square tile formats. Install
tiles running in the same direction (block or staggered), quarter-turned
or as specified by architect. LVT plank flooring should have end-joints
offset by at least 6" and should be installed in a staggered manner,
so as to create a random appearance that avoids alignment of endjoints. LVT can be laid out to run either parallel or diagonal to the room
or primary wall. The following conditions must be given consideration
when determining how LVT will be installed:
Layout: Layout shall be specified by the architect, designer or end user
(refer to architectural drawings).
•Establish center lines and determine starting point to balance the
installation by having equal tile widths on opposite sides of room.
This can be facilitated by measuring or dry-laying tiles and marking
baselines.
•
Wet-Set Applications: The room layout must be arranged so that
all flooring can be installed while working off of freshly installed tiles.
Installation Method
Glue Down
This will keep tiles from shifting, minimize adhesive displacement,
and prevent wet adhesive from oozing up and getting onto the
surface of the tiles. This can be accomplished by snapping chalk
lines to create work zones that are no wider than a comfortable arm’s
reach, and in multiples of the tile or plank width. Periodically pull back
a tile or plank during installation and check for adhesive transfer to
backing.
•When all preparatory work is satisfactorily completed, including dry
fitting cut tiles (if applicable), proceed with installation. Inspect each
tile for visual defects before installing. Installation of flooring implies
acceptance of materials.
•
Protecting Newly Installed Floors: Newly installed flooring must be
protected while the adhesive sets, and also protected from damage
of other trades. Early foot traffic, as well as point or rolling loads,
can cause shifting of tiles, adhesive displacement, or breaking of the
bond between the adhesive and the tile or substrate.
Always start with a clean jobsite. All trades must finish before
installing LVT. Carefully inspect each plank or tile for defects prior
to installation, and do not install damaged material. Be sure to
check run numbers/manufacture dates prior to installing.
TILE INSTALLATION
STEP 1: SQUARE THE ROOM
Square the layout of the room, find the
center of one end of the room. Locate
5’
the same point at the other end-wall.
4’
Snap a chalk line between these points
to mark the center line on the floor. Then,
3’
measure along this center line to find the
middle of the room. At the center point,
mark off a line across the room at precise
right angles to the first line This can be
Figure 1
accomplished using the 3-4-5 triangle
method. Starting from the center point,
make a mark measuring 4 feet vertically and 3 feet horizontally. Connect
the marks with a diagonal line to complete the triangle. If the diagonal
line does not measure exactly 5 feet, then the center crossing lines are
not at a true right angle. (See Figure 1)
TIP: Multiples of the 3-4-5 triangle method may be used for greater
accuracy in large rooms (e.g. 6-8-10, 9-12-15, etc.).
STEP 2: BALANCE THE ROOM
Either measure or dry-lay a row of tiles
from the center line to the side wall to
determine the size of the first and last
tiles. If the resulting border is too small
in either direction, move the row of tiles
over one-half tiles’ width and snap a new
line. This becomes your new starting
line. (See Figure 2)
TIP: Use the dimensions of the room
to calculate the size of the first tile
without dry-laying.
STEP 3: INSTALL THE TILES
After determining the layout and snapping
center line, spread adhesive and install flooring
as outlined below using the dry to touch or wetset application method. (See Figure 3)

Product Description
Dryback LVT/LVP
Pressure Sensitive (dry-to-touch) Applications: Lay tiles from the
center of the room in a pyramid fashion while working towards the walls
as shown in Figure 3. The dry, tacky adhesive makes it possible to work
on top of the material without compromising the installation.
Wet-Set Applications: The room layout must be set-up so that all flooring
can be installed while working off of freshly installed tiles. This will keep
tiles from shifting, minimize adhesive displacement, and prevent wet
adhesive from oozing up and getting onto the surface of the tiles. This
can be accomplished by creating work zones outlined with parallel chalk
lines. Create work zones that are no wider than the installer’s comfortable
arm reach and in multiples of the tile width. Measure and snap chalk line
parallel to the established base line. Spread adhesive within the work
zone, and begin installing tiles using the row-by-row method, as shown in
Figure B under “LVT Resilient Plank Installation” (next section).
TIP: Do not apply more adhesive than can be worked within
the recommended working time. Always follow the adhesive
manufacturer’s recommendations.
IMPORTANT: All LVT flooring must be rolled with a minimum 100lb
roller after installation. Use a hand roller in areas that cannot be reached
with a 100lb roller.
PLANK INSTALLATION
STEP 1: SQUARE THE ROOM
To square the layout of the room, find the center of one end of the room.
Locate the same point at the other endwall. Snap a chalk line between these
points to mark the center line on the
5’
4’
floor. Then, measure along this center
line to find the middle of the room. At the
center point, mark off a line across the
3’
room at precise right angles to the first
line. This can be accomplished using the
3-4-5 triangle method. Starting from the
center point, make a mark measuring
Figure A
4 feet vertically and 3 feet horizontally.
Connect the marks with a diagonal line
to complete the triangle. If the diagonal line does not measure exactly
5 feet, then the center crossing lines are not at a true right angle. (See
Figure A)

CARE & MAINTENANCE
LVT DRYBACK GENERAL CARE & MAINTENANCE
LVT dryback flooring is manufactured with a high-performance, UVcured urethane and ceramic bead coating, which provides improved
maintenance characteristics and options for the end-user in commercial
environments. All floor coverings require some care to look their best, and
many problems can be prevented before they occur. The area of usage,
type of traffic, and frequency of traffic on the floor will determine the type
and frequency of maintenance needed. Proper care and maintenance
are an essential part of keeping your LVT flooring attractive and safe.
These guidelines will help to maintain the appearance of and extend the
life of your LVT flooring.
FLOOR-CARE BEST PRACTICES
• Sweep or vacuum daily; use only vacuums without beater bars.
• Protect the floor from tracked-in dirt and grit particles by using walk-off
mats at all outside entrances.
• Avoid the use of rubber-backed mats, as certain rubber compounds can
permanently stain vinyl.
• In order to prevent indentations and scratches, provide glass, plastic,
felt, or other non-staining cups with flat under-surfaces not less than 2"
wide for the legs of heavy furniture or appliances. Equip swiveled-type
office chairs and other rolling furniture with broad-surface, non-staining
casters at least 2” in diameter. Remove small diameter buttons from
the legs of straight chairs and replace with metal or felt glides that have
bearing surfaces no less than 1" in diameter.
TIP: For large rooms, multiples of the above dimensions may be
used to obtain greater accuracy. (6-8-10, 9-12-15, and so on.)
• Always use the proper equipment to protect the flooring from damage
that could be caused by the moving of heavy fixtures or appliances.
STEP 2: INSTALL THE PLANKS
• Never use anything coarser than 3M-equivalent red cleaning pads
or brushes on LVT resilient flooring (see Maintenance Procedures
section).
After snapping the center starting chalk
lines, spread the appropriate adhesive
on the center lines, leaving portions of
the lines at center and near each wall
uncovered. Start laying the planks from
the right angle formed by the center
lines. Lay the material from the center of
the room, working towards the walls as
shown. It is imperative that the first row is
placed precisely and accurately against
the reference line as you install. Make
sure each plank is flush against the chalk
line and tight against the adjoining plank.
The ends of the planks should align
perfectly. Lay row-by-row or in pyramid
fashion (See Figures B & C).
• The use of aggressive strippers, such as mop-on/mop-off, no-scrub and
no-rinse strippers, may affect the adhesive bond.
Row by Row
Figure B
• Protect your floor against burns. Burns from the glowing end of
cigarettes, matches, or other extremely hot items can damage LVT
floors.
• Do not flood floor or subject to frequent standing water.
• Only use premium cleaning products that are designed for Luxury Vinyl
Tile (LVT) floors with urethane coatings.
Pyramid
Figure C
TIP: Pay special attention to the edges of the planks. Do not slide the
planks through the adhesive as you install.
IMPORTANT: All LVT flooring must be rolled with a minimum 100lb
roller after installation. Use a hand roller in areas that cannot be reached.
• All LVT floors have good resistance to stains and are not affected by most
common spills. However, any spill should be cleaned up immediately.
The longer the spilled materials are left on the floor, the greater the risk
of permanently staining the floor. For information regarding the proper
method or solution to use on a specific stain, contact Customer Service.
• Avoid exposure to direct sunlight for prolonged periods. The use of
drapes or blinds is recommended during peak sunlight hours. Prolonged
exposure to direct sunlight can result in discoloration, and excessive
temperatures might cause tiles or planks to expand.

MAINTENANCE PROCEDURES
Safety: When performing wet maintenance, always use proper signage and
prohibit traffic until the floor is completely dry. Always use caution and follow
electrical equipment manufacturer’s safety instructions.
NO-POLISHING/NO-BUFFING MAINTENANCE OPTIONS
Initial Maintenance for a Newly Installed floor
1.Allow the adhesive to cure for at least 48 hours prior to wet-cleaning the
floor.
2.Thoroughly sweep, dust-mop, or vacuum (without beater bar assembly)
the floor to remove all loose dirt, dust, grit, and debris.
3.Remove any dried adhesive-residue from the surface with a premium
neutral pH cleaner, or with mineral spirits applied to a clean, lint-free
cloth. Do not allow excessive amounts of solvent to sit on the vinyl
or to penetrate the joints of the flooring. NEVER APPLY SOLVENT
DIRECTLY TO FLOORING.
4.Damp-mop the floor using a premium neutral pH cleaner.
5.If necessary, scrub the floor using an auto scrubber or rotary machine
(175 rpm or less) with a premium neutral pH cleaner, using the proper
dilution ratio and the appropriate scrubbing brush or pad. Fit the buffer
with a 3M-equivalent red or white scrubbing pad and work the solution
over the floor.
6.Thoroughly rinse the entire floor with fresh, clean water. Remove the dirty
residue with a wet-vacuum or with a clean mop and allow the floor to dry
completely.
DAILY/ROUTINE MAINTENANCE
1.Clean entryway walk-off mats to remove dirt, grit, sand and other
contaminants from being tracked onto the floor (as needed).
2.Thoroughly sweep, dust-mop, or vacuum (without beater bar assembly)
the floor to remove all loose dirt, dust, grit, and debris that can stick to and
damage the surface of the floor.
3.Spills should be cleaned up immediately. Spot-clean using a premium
neutral pH cleaner and micro fiber or preferred mop.
4.Damp-mop the floor on a regular (recommended - daily) basis using a
premium neutral pH cleaner.
PERIODIC MAINTENANCE
Installation Method
Glue Down
3.Apply two or more coats of a premium matte or gloss specifically
designed for LVT flooring.
4.Apply additional coats of floor finish (only as needed). Refer to
manufacturers instructions.
GENERAL RECOMMENDATIONS FOR SPRAY BUFF OPTION:
1.After completing Steps 1 and 2 under the “Initial Maintenance for
a Newly-Installed Floor” section, machine-scrub the floor with a
premium neutral pH cleaner, using the proper dilution ratio. Fit the
buffer with a 3M-equivalent red or white scrubbing pad and work the
solution over the floor to remove contamination and promote adhesion.
NOTE: Always use a premium quality product specifically designed
for LVT flooring and follow the manufacturers instructions.
2.Thoroughly rinse the entire floor with fresh, clean water. Remove the dirty
residue with a wet-vacuum or with a clean mop and allow the floor to dry
completely.
3.Using a handheld spray-bottle with a premium matte or gloss finish,
and working in small areas (10 x 10 foot), lightly mist the floor and buff
using an auto scrubber or rotary machine (175 rpm or less) fitted with a
3M-equivalent red pad.
4.Routine (recommended - daily) and periodic maintenance should be
performed, as stated in above sections.
5.Machine-scrubbing should always be conducted prior to spray buffing.
RESTORATIVE MAINTENANCE
1.Mix vinyl stripper solution per instruction-label. Blockade and set up
caution signs. Using a clean, string mop, apply liberal amounts of solution
onto the floor and allow to soak per the instructions. Rewet if necessary.
2.Using a low speed machine (175 rpm or less), scrub the floor with a
scrubbing brush or pad equivalent to a 3M red pad.
3.Use a wet-vacuum or a clean mop to remove the dirty stripping solution.
If the floor begins to dry, it may be necessary to drizzle fresh, clean water
onto the stripper solution to remove it.
4.Thoroughly rinse the entire floor with fresh, clean water. Remove the dirty
residue with a wet-vacuum or with a clean mop and allow the floor to dry
completely.
5.Next, start over by following the Finish option.
1.When necessary, scrub the floor using an auto scrubber or rotary
machine (175 rpm or less) with a premium neutral pH cleaner, using
the proper dilution ratio. Fit the buffer with a 3M-equivalent red or white
scrubbing pad and work the solution over the floor.
OPERATING ROOMS
2.Thoroughly rinse the entire floor with fresh, clean water. Remove the dirty
residue with a wet-vacuum or with a clean mop and allow the floor to dry
completely.
AUTOMATIC SCRUBBERS
ALTERNATIVE MAINTENANCE OPTIONS
Alternative maintenance options provide end-users with the flexibility of
using different methods to maintain their floors, based upon the needs of
the area of usage. LVT floors may be maintained using the Finish Option or
the Spray Buff Option, as detailed below.
GENERAL RECOMMENDATIONS FOR FINISH OPTION:
1.
After completing Steps 1 and 2 under the “Initial Maintenance
for a Newly-Installed Floor” section, scrub the floor using an auto
scrubber or rotary machine (175 rpm or less) with a premium neutral
pH cleaner, using the proper dilution ratio. Fit the buffer with a
3M-equivalent red or white scrubbing pad and work the solution
over the floor to remove contamination and promote adhesion.
NOTE: Always use a premium quality product specifically designed
for LVT flooring and follow the manufacturers instructions.
2.Thoroughly rinse the entire floor with fresh, clean water. Remove the dirty
residue with a wet-vacuum or with a clean mop and allow the floor to dry
completely.
The frequent use of disinfectants in operating rooms will make
the use of floor finish impractical. DO NOT USE PHENOLIC
DISINFECTANTS ON ANY FLOOR.
Automatic scrubbers come in walk-behind and ride-on styles with some
being compact for hard-to-reach areas around equipment or fixed seating.
Auto Scrubbers are efficient, safe and cost effective delivering substantial
time savings compared to the mop and bucket method of floor maintenance.
STAIN REMOVAL
To remove stubborn spots and stains from LVT floors, always begin with
mild cleaners, such as a premium neutral pH cleaner. If such cleaners fail to
remove the spots and stains, and “if permitted,” use mineral spirits. Do not
use harsh solvents, such as lacquer thinner or straight acetone, as these
can permanently soften and damage the vinyl surface.
For stubborn spots and stains (such as paints, permanent markers, and
dyes), and “if permitted,” try applying fingernail polish remover containing
acetone (do not use straight acetone) to a soft cloth and rubbing across
the affected areas. Subsequent to this cleaning procedure for stubborn
spots and stains, please clean the affected area with clear water to remove
any residue. Any damage resulting from the use of pure solvents IS NOT
covered by the LVT Warranty. Always test stronger cleaning agents on
sample pieces or in unnoticeable areas first.
Never use a brush or pad more aggressive than a 3M red equivalent. Blue,
Green, Brown and Black pads will damage the surface of the floor.
