1. Substrate Preparation
General Substrate Guidelines
Ensure the substrate is clean, dry, at, sound and
suitably prepared according to these instructions prior
to installation, as manufacturer is not responsible for
problems related to substrates that have not been
properly prepared. All substrates must be free of visible
water or moisture, dust, residual adhesives and adhesive
removers, solvents, wax, oil, grease, asphalt, visible
alkaline salts or excessive eorescence, mold, mildew
and all other extraneous coating, lm, material or foreign
matter. Substrate and/or suboor deection, movement, or
instability may cause issues with the ooring installation –
these are not covered under warranty.
Flatness Guidelines
Check all substrates for atness prior to installation. All
substrates must have a oor atness of FF32 and/or have
a maximum deviation of < 1/8-in. gap (2 x US quarters
should not slide underneath) within 6-ft. and ≤ 1/16-in. gap
(1 x US quarter should not slide underneath) within 1-ft..
Substrates that do not meet this requirement must be
corrected appropriately before installation begins.
Concrete Substrates
All concrete must be at least 28-days old, free of
contaminates and structurally sound. If required, atten
and/or smooth the surface using a suitable, moisture-
resistant, commercial-grade leveling or patching
compound, following the product instructions. Do not
install if water or hydrostatic pressure is visible, present or
suspected. If a chemical adhesive remover has been used,
contact the technical department.
All expansion joints must have a suitable expansion joint
covering system installed to allow for expansion and
contraction of the concrete. All dormant construction joints
and surface cracks > 1/4-in. must be cleared of all dust, dirt
and debris and lled with a rigid crack treatment designed
for use in construction joints or cracks. Follow the products
instructions and ensure surface is troweled ush with
surface of concrete.
Concrete Moisture Requirements
All on and below-grade concrete must have a conrmed
and eective vapor retarder that is compliant with ASTM
E1745 installed directly beneath the slab. All concrete
substrates must be tested for moisture in accordance with
the adhesive in use and must be below all published limits.
If a vapor retarder is not present, conrmed or adequate
and/or if the results of concrete moisture testing exceed
the published limits, a suitable concrete moisture
mitigation product must be installed, following the product
instructions.
Installation Instructions
Concrete Moisture Mitigation
When appropriate, use a dimensionally stable, surface-
applied moisture mitigation system that, when tested in
accordance with ASTM E96 / E96M Standard Test Methods
for Water Vapor Transmission of Materials (Method B),
has a permeability value of ≤ 0.1 grains/sq. ft./hr. Conrm
compliance with the manufacturer before use.
Gypsum / Lightweight Concrete Substrates
Lightweight or gypsum substrates must be dry (according
to the product manufacturer’s requirements) and have
a minimum compressive strength of 2000 PSI when
installed over a wood substrate or 3000 PSI when
installed over a concrete substrate. Lightweight or gypsum
substrates must be installed and prepared in accordance
with ASTM F2419 or ASTM F2471, respectively. Gypsum
and lightweight substrates must be rmly bonded to a
structurally sound suboor. All cracked or fractured areas
must be removed and repaired with a compatible repair
product. New or existing gypsum or lightweight substrates
may require a sealant or primer be installed prior to resilient
ooring installation - follow the product manufacturer’s
recommendations regarding preparation for resilient
ooring.
Wood Substrates
All wood substrates must be structurally sound, dry
and within the moisture content percent (MC%) for your
region. Wood substrates and suboors must be compliant
with and, if necessary, prepared in accordance with
ASTM F1482. Wood substrates should be of double layer
construction with a recommended total thickness of 1-in.
or more, depending on federal, state and local building
codes. Sleepers and sleeper systems must not make direct
contact with concrete.
Resinous Coating Substrates
When installing directly over a resinous coating, such as
an epoxy coating or a moisture mitigation system, ensure
the coating is clean and free of contaminates, structurally
sound, smooth, dry and has cured for the prescribed length
of time.
Metal Substrates
Metal substrates must be clean, dry, structurally sound
smooth and free of oil, rust and/or oxidation. When installing
in areas that may be subject to topical water, moisture
and/or high humidity, an anti-corrosive coating should be
applied to protect the metal substrate. Contact a local paint
or coating supplier for coating recommendations.
Other Substrates
Installing over existing resilient vinyl ooring is not
recommended. However, it may be possible over some
materials, such as VCT, quartz tile, solid vinyl tile, sheet
