The following items may be purchased from a local carpet wo rkroom supplier:
 Razor Blades Razor Knives
 Straight Edge Chalk line
 Mohawk Group’s Adhesives Scissors
 Framing Square Floor Scraper
 Cushion Back Cutter 75 lb. Roller or 100 lb. Roller
 Tape Measure Portland Patching Compound
 1/16” x 1/16” x 1/16” square notch trowel (Ecoflex AIR Cushion)
 Heavy Duty Frame Paint Roller with 3/8” Nap Roller or a 1/16” x 1/32” x 1/32” U-notch
trowel (Ecoflex ICT and Ecoflex NXT)
Floor Priming
Concrete: Prime if floor is extremely porous or has excessive dust. Note: Any existing sealer
or primer must be tested for compatibility with Mohawk Group’s adhesives. Terrazzo, Marble,
Vinyl Tile (VAT or VCT), Linoleum and other smooth nonporous surfaces do not require priming.
Damp mop only, if patching is required on these areas, prime the patched areas if required by
patch manufacture.
NOTE: When non-asbestos containing cut-back or any incompatible adhesive is
present, existing adhesive has evidence of plasticizer migration, or EcoFlex ICT
(PVC) products are being installed, the existing adhesive must be properly
removed and Mohawk Group’s OptiSeal must be applied over the adhesive
residue. Chemical adhesive removers cannot be used to remove old existing
adhesives.
A bond test must be performed over concrete substrates with unidentified sealers or primers:
Adhere a small area of 2-3 feet of carpet and allow it to dry completely. Let it set for 24 hours.
If the adhesive is bonded tightly, proceed with installation.
Plywood Floors: Plywood Floors must be completely primed. Plywood substrates must be no
less than 3/4” thickness. Particleboard or thin plywood is not an acceptable substrate.
Site Layout
1. The starting point in a modular installation must be as near to the center of the room as
possible and must be positioned to utilize the largest perimeter cut module size.
2. Snap a chalk line parallel to one major wall bisecting the starting point. It will be necessary
to offset the center chalk line to assure perimeter modules will be at least half size.
3. A second chalk line must be snapped from the starting point at 90° to the first line. This can
be accomplished using a 6-8-10, or larger triangle, depending on the room size. (See
below) Meters or feet will be used to lie out the triangle in these proportions. Framing
square can also be used.

Pallet and Box Sequencing
It is very important to install carpet tiles in the order they were manufactured. This is easily
accomplished by selecting pallets in sequential order.
