Removal of Existing Floor Covering and
Adhesive”, and all applicable local, state,
federal and industry regulations and
guidelines. When removing asbestos
and asbestos containing materials,
follow all applicable OSHA standards.
CONCRETE SUBSTRATES
All concrete must have a minimum
compressive strength of 3500 PSI and
be prepared in accordance with ASTM
F710. When flooring is being installed
directly over concrete, concrete surfaces
that have an ICRI Concrete Surface
Profile (CSP) over 4 should be flattened
with a self-leveling underlayment or a
patch to prevent imperfections from
telegraphing through flooring materials.
On or below grade concrete must have
a permanent, effective moisture vapor
retarder installed below the slab.
New or existing concrete substrates
on all grade levels must be tested in
accordance with ASTM F2170, using in
situ Probes, to quantitatively determine
the amount of relative humidity no more
than one week prior to the installation.
In addition to ASTM F2170 Relative
Humidity Testing, existing concrete
that has previously had floor covering
installed on all grade levels must be
tested in accordance with ASTM F1869,
using Calcium Chloride test kits, to
quantitatively determine the Moisture
Vapor Emissions Rate (MVER) of the
concrete.
If ASTM F2170 or ASTM F1869 test
results exceed the prescribed limits, a
moisture mitigation product, such as
Excelsior MM-100 Moisture Mitigation,
must be installed prior to proceeding
with installation. Install The MM-100
per technical data sheet at a rate of 400
sq. ft. per gallon. When installing over
concrete as moisture mitigation, material
must be applied in two coats. Do not
install flooring until moisture testing has
been conducted per the appropriate
standard and/or moisture mitigation has
been installed and is dry to the touch. Do
not install flooring in below grade areas
when hydrostatic pressure is visible or
suspected.
RESINOUS SUBSTRATES
When installing directly over a resinous
products, such as the Excelsior MM-
100 or an epoxy coating, ensure that
coating is dry to the touch and has
cured for the prescribed length of time.
Substrate must be clean, dry, sound and
free of contaminates. Ensure to follow
installation procedures and trowel sizes
for non-porous substrates.
GYPSUM BASED SUBSTRATES
Gypsum-based substrates must have a
minimum compressive strength of 3500
PSI. Gypsum substrates that do not meet
this requirement must have one coat
of the Excelsior MM-100 or equivalent
installed to improve the tensile/pull-
off strength of the substrate. Substrate
must be structurally sound and firmly
bonded to subfloor. Any cracked or
fractured areas must be removed and
repaired with a compatible patch or
repair product. Follow instructions for
installation over a gypsum substrate.
New or existing gypsum substrates
may require a sealant or primer. Follow
all manufacturer’s recommendations
regarding preparation for resilient
flooring installation.
WOOD SUBSTRATES
Wood substrates must be prepared in
accordance with ASTM F1482. Wood
subfloors should be of double layer
construction with a minimum thickness of
1”. Crawl spaces beneath wood subfloors
shall be in compliance with local building
sound. Substrates must be free of
visible water or moisture, dust, sealers,
paint, sweeping compounds, curing
compounds, residual adhesives and
adhesive removers, concrete hardeners
or densifiers, solvents, wax, oil, grease,
asphalt, visible alkaline salts or excessive
efflorescence, mold, mildew and any
other extraneous coating, film, material
or foreign matter.
All substrates must have any and
all existing adhesives, materials,
contaminants or bond-breakers
mechanically removed via scraping,
sanding, grinding or buffing with a 25
grit DiamaBrush Prep Plus tool prior
to adhesive installation. In extreme
situations, shotblasting may be required.
Mechanical preparation must expose
at least 90% of the original substrate.
Following cleaning and removal, all
substrates must be vacuumed with a flat
vacuum attachment or damp mopped
with clean, potable water to remove
all surface dust. Sweeping without
vacuuming or damp mopping will not
be acceptable.
All porous substrates must be tested
per ASTM F3191 to confirm porosity.
Use a pipette or equivalent to conduct
three tests by placing a .05 mL (1/4”
wide) droplet of clean, potable water
onto the surface. If the substrate absorbs
water within 60 seconds, the substrate
is considered porous. Conduct 3 tests
for the first 3000 sq. ft. and one for each
additional 2000 sq. ft., at least one per
room. All other substrates that do not
meet this requirement are considered
non-porous. Ensure that all non-porous
substrates are not contaminated with any
aforementioned contaminates.
It is recommended that all substrates
have a floor flatness of FF32 and/or a
flatness tolerance of 1/8” in 6’ or 3/16”
in 10’. Substrates that do not meet this
requirement should have a compatible
cementitious patch (such as the Excelsior
CP-300) or self-leveling underlayment
(such as the Excelsior SU-310) installed
to flatten the installation area.
Do not use solvent/citrus based adhesive
removers prior to installation. Follow
