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 substrates 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. For all on and below grade concrete

substrates refer to "Concrete Moisture Requirements".

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

For all On and/or Below Grade concrete substrates, test

the surface to conrm it is absorbent (porous). Follow the

ASTM F3191 Standard Practice for Field Determination of

Substrate Water Absorption (Porosity) for Substrates to

Receive Resilient Flooring - water droplet(s) placed on the

surface must be absorbed into the concrete within 12-hours

for the surface to be considered absorbent. If required, the

concrete can be made porous by mechanical methods, such

as diamond grinding, a DiamaBrush buer attachment,

shotblasting or similar.

Installation Instructions

If the substrate cannot be made porous and will not have

a topical moisture mitigation system installed, install a ≥

6-mil thick polyethylene (PE) sheet, which is available at

most home improvement stores. Use sheeting that is ≤ 10-

ft. wide to prevent wrinkles and folds. Sheeting must be

installed over the entire area and extend at least 2-in. up the

walls. All seams must be overlapped and sealed according

to the product instructions.

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 VAT, VCT, quartz tile, solid vinyl tile, sheet
