Concrete Testing
Moisture Testing: It is the responsibility of the flooring contractor and the installer to confirm 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 floor 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 iGrip adhesive.
PH LEVELS: PH must be between 5 and 9
Floor Preparation
• Remove all foreign substances such as wax, grease, dirt and any substance or chemical that
could interfere with a good bond.
• Fill all holes and cracks with a latex fortified Portland cement based patching compound. IVC US
only recommends use of latex fortified Portland cement based products as a satisfactory
patching or leveling compound.
• IVC US recommends priming the floor with FLEX-PRIM Acrylic Latex Primer to prevent over
absorption of adhesives, contain dust, and to insure a better bond of adhesive to the subfloor.
• Inspect all material prior to installation. Report any defects to the location where the flooring was
purchased
