Storage and Handling
Acclimate the flooring for a minimum of 48 hours before installation in the area where it will be installed. Conditions
between 65°F and 85°F (18°C and 29°C) are required before, during and after installation. Cartons should be evenly
stacked no more than five high on a flat surface and away from any heating/cooling ducts or direct sunlight.
Floor Preparation
Floor must be clean, smooth, flat and dry. Remove all foreign substances, such as wax, grease, dirt, construction
marks and contaminants, and any substance or chemical that would interfere with a good bond. Avoid using
sweeping compounds. Do not install over substrates that have been chemically cleaned. Wood subfloor or
underlayment must be flat, not to exceed variation of 1/4 inch in 10 feet (1/2 cm in 3 m).
The flatness of concrete subfloors must meet or exceed the requirements of ACI FF25. Fill all holes and cracks with a
latex fortified Portland cement based patching compound.
Mohawk recommends priming extremely porous floors with Mohawk PrimeCoat Acrylic Latex Primer to prevent over
absorption of adhesives, for dust containment, and to insure a better bond of the adhesive to the subfloor or
underlayment.
Suitability: Regardless of the type of concrete or cement-like material used as a base for Mohawk LVT glue down
products, the responsibility for its use or suitability rests with that product’s manufacturer or specifier and not with
Mohawk.
Moisture Testing: It is the responsibility of the flooring contractor and the installer to test all concrete substrates,
both old and new, for moisture transmission using the Calcium Chloride Moisture Test according to ASTM F1869.
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. Also test for relative humidity in concrete
floor slabs using in-situ probes, which should be no more than 90% RH per ASTM F2170 before, during and after
installation.
These acceptable moisture readings are only applicable when using MVONE for Luxury Vinyl Tile & Plank adhesive.
