• 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 Henry 366 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, sealers 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 Henry 366 Primer to prevent over absorption of adhesives, dust containment, and to ensure 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 5 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 75% RH per ASTM F-2170 before, during and after installation.
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 between 65° F and 85° F (18°C and 29°C) for 24 hours before, during and after installation.
PLEASE NOTE: If removal of existing resilient oor covering is required, follow all recommended Resilient Floor Covering Institute (RFCI) work practices
at www.rfci.com.
Permanent Full Spread Installation Steps:
Step 1
Align the pattern with the most dominant wall. Using a sharp utility knife, trim away excess material along the walls, cabinet and other permanent objects,
leaving approximately 2” of material to be trimmed off later.
Step 2
Make relief cuts at corners to allow the material to lay at before the nal cuts are made. Final trimming does not require a 1/8” to 1/4” expansion gap when
using M640 Pressure Sensitive Releasable Adhesive as this is a permanent installation.
Step 3
Fold back half of the material and apply Roberts 2310 Adhesive to the substrate using the appropriate trowel. If a seam is required, leave an 18” dry zone at the
edge of the seam. Then follow the Seaming Instructions in the Permanent Full Spread Residential Installation section found below.
Step 4
Do not immediately place the material into wet adhesive. To avoid bubbling, allow time for the adhesive to ash before positioning the material.
Step 5
Slide the material in place and remove air and vapors under the material using a vinyl oor roller over the entire adhered vinyl.
Step 6
Repeat steps 3-5 for the remaining half of the ooring material.
