CONCRETE SUBFLOORS
GENERAL CONDITIONS
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
installed beneath the slab (ASTM E1745). The surface of concrete
structurally sound. They shall be free of dust, solvent, paint, wax, oil,
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
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,
installation.
Fly ash is
continue to grow in popularity as LEED points become the norm in
commercial construction. Fly ash contains silicon dioxide and calcium
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 4).
Concrete
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
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:
surface to prevent any irregularities or roughness from telegraphing
Concrete PSI: Concrete substrates must have compression strength
of 3,000 psi or greater.
Concrete Absorbency: Be aware that absorbent (porous) and non-
for adhesive application. Check absorbency by randomly placing 1"
diameter droplets of water directly onto the surface of the concrete
then the substrate is considered non- absorbent. Even after removing
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
permit
movement without causing random cracks in the concrete. These joints
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
or smoothed with high-quality Portland cement-based patching or
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
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
compounds may have very high moisture content, thus requiring longer
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,
become a bond breaker, causing tiles to release at the interface
unnecessary, added expense
NEW CONCRETE
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
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.
