All warranties and guarantees pertaining to the
suitability and performance of any preparation or
ancillary product rests with that material
manufacturer or the Flooring Contractor and NOT
with NUFLORS™. The condition of the subfloor and
bond issues resulting from improper subfloor
preparation and/or the use of incorrectly prepared
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 products.
WARNING: ASBESTOS & SILICA –
Various Federal,
State, and Local government agencies have
regulations governing the removal of in-place
asbestos- containing 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.
CHEMICAL ABATEMENT:
NUFLORS™ does not
recommend the use of solvent adhesive removers
(inorganic or bio-based) or chemically abating
an existing floor covering or adhesive. Adhesive
removers can remain in the slab, under walls and
within cracks and cause failure of the new
floor covering after installation. For removal of all
flooring and adhesives, follow the resilient flooring
removal procedure as detailed in the
RFCI’s Recommended Workplace Practices for
Removal of Resilient Floor Coverings.
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, ASTM F1482 and 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 SETAGRIP™ 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. Interior environmental conditions must be
maintained at 65°-85°F (18°-29°C) and 35%-65%
RH a minimum of 48 hours before testing, and at all
times during testing (ASTM F710).
3. Moisture Testing: Perform one or more of the
moisture evaluation methods listed to determine
the moisture levels of the subfloor.
CONCRETE SUBFLOORS
A.
Electronic Moisture Meter: Using a Tramex
Concrete Moisture Encounter Meter, Check the
moisture level of the surface of the concrete slab.
The moisture limit is 4.0%.
B.
Mat Test (ASTM D4263): Duct tape 2 ft. x 2 ft.
pieces of plastic sheet down to the surface of the
concrete making sure the edges are completely
secure. After 24 hours, peel back the plastic. The
limit is darkness and dampness but no water drops.
Any beads of water on the slab or on the plastic are
not acceptable.
C.
Calcium Chloride Test (ASTM F1869): Place the
calcium chloride tests as specified in the current
ASTM F1869. The maximum limit is 8.0 lbs. MVER.
D.
In-Situ Relative Humidity (RH) Test (ASTM
F2170): Place the RH probes as specified in the
current ASTM F2170. The maximum limit is 90.0%
RH.
E.
Alkalinity testing is not required.
WOOD SUBFLOORS
A. Pin Wood Moisture Meter: Wood substrates
must be checked with a calibrated pin moisture
meter. Readings between the subfloor / structural
wood and underlayment panels must be within
3.0% and be less than 14.0% moisture content.
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.
