OSB (underlayment grade)
OSB underlayment panels must be underlayment grade as specied and warranted by the manufacturer. Underlayment panels and joints must be
fastened and reinforced according to manufacturer’s instructions. Completely sand the oor with a oor sander, so that the oor is smooth and
at. Note: The chips in OSB overlap. Without sanding properly, OSB has high and low spots throughout the oor that could telegraph through the
vinyl.
- Surface must be primed using IVC FLEX-PRIM Acrylic Latex Primer.
Particle Board (underlayment grade)
Particle board underlayment panels must be underlayment grade as specied and warranted by the manufacturer.
- Surface must be primed using IVC FLEX-PRIM Acrylic Latex Primer.
Unacceptable Surfaces
• Inter-ex and any perimeter bonded products • Carpet
• Any oating oor system • Cork
• Resilient tile installed below grade • Cushion-back vinyl
Mohawk will not warrant or accept responsibility of any kind for ooring failures related to the use of unacceptable substrates and surfaces.
Floor Preparation
Floor must be clean, smooth, at and dry. Remove all foreign substances such as wax, grease, dirt, construction markings, paints, sealeres and
contaminants, and any substance or chemical that would interfere with a good bond. Fill all holes and cracks with a latex fortied
Portland cement based patching compound. Mohawk only recommends the use of latex fortied Portland cement based products as a
satisfactory patching or leveling compound.
Mohawk recommends priming extremely porous oors with IVC FLEX -PRIM Acrylic Latex Primer to prevent over absorption of adhesives, dust
containment, and to insure a better bond of the adhesive to the suboor/underlayment.
Moisture Testing: It is the responsibility of the ooring contractor and the installer to conrm all concrete substrates, both old and new, for
moisture transmission using the Calcium Chloride Moisture Test according to ASTM F-1869. Moisture vapor transmission should not exceed the
recommended levels of 8 lbs. or less per 1,000 sq. ft. in 24 hours. This test should be performed and documented prior to installation.
A second testing option determines relative humidity in concrete oor slabs using In-Situ Probes, which should be less than 90% RH per ASTM
F-2170 before, during and after installation. These acceptable moisture readings are only applicable when using IVC FLEX-TECH adhesive
for sheet vinyl.
PH LEVELS: PH must be between 5 and 9
Inspection of ooring material prior to installation is required. Any defects should be immediately reported to the retail store from which the
ooring was purchased before installation.
Mohawk will not be responsible for labor costs to repair or replace material with defects that were apparent before or noticed at the end of an
installation. The job site and all ooring material and adhesive must be kept for 24 hours before, during and after installation between 65° F and
85° F (18°C and 29°C).
PLEASE NOTE: If removal of existing resilient oor covering is required, follow all recommended Resilient Floor Covering Institute
(RFC) work practices at www.rfci.com.
