• Concrete
• VCT (well bonded, on and above grade)
• Ceramic (well bonded) with a skim coat
• Terrazzo (well bonded)
• Self-leveling and patching compounds (latex fortied Portland cement based only)
• Resilient oor (no more than 2 layers, well bonded, non-cushioned – residential applications only)
• Radiant heat oors (not exceeding 85°F (29°C) and approved by the manufacturer for the use of their product with resilient vinyl ooring
applications)
• Gypcrete can be utilized when necessary due to radiant heat and in high rise buildings. Gypcrete must be sealed using IVC FLEX-PRIM Acrylic
Latex Primer to stabilize the surface for adhesive bond. All issues with gypcrete cracking, crumbling, powdering and resulting in the release of
adhesive bond are NOT warranted by Mohawk.

Floor Preparation
Floor must be clean, smooth, at and dry. Remove all foreign substances such as wax, grease, dirt, construction markings 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. Sand high spots to eliminate the possibility of telegraphing. Prime oor if needed with IVC FLEX -PRIM Acrylic Latex Primer to
prevent over absorption of adhesives, dust containment, and to ensure a better bond of the adhesive to the suboor.
PH must be between 5 and 9; or, if using ASTM F-2170 In-Situ Probes should be less than 75% relative humidity.
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).
